The 1830 PSS Engineering and Planning Tool Introductioon to 1830 PSS EPT
The 1830 PSS Engineering and Planning Tool (EPT) is a software tool for automated design and planning of photonic networks based on the 1830 Photonic Service Switch PSS portfolio of WDM products. The EPT is one key component of Nokia’s Zero Touch Photonics networking innovation, which enables easier operations, accelerated time-to-market and optimized total cost of ownership (TCO) of wavelength services. The EPT runs on a windows-based platform and employs a graphical user interface (GUI) to simplify the network design process. EPT integration with the 1830 PSS management systems and WaveTracker OA&M support both initial system turn-up as well as incremental network growth. The 1830 Photonic Service Switch PSS-36 and PSS-64 are supported by Nokia 1390 Network Planning Tool (NPT). The Nokia 1390 NPT application provides integrated planning and design capabilities for the Nokia 1830 PSS family equipment. Nokia 1390 NPT has the capability to plan across both the photonic and electrical layers. The complete 1830 Photonic Service Switch PSS Engineering Planning Tool (EPT) is embedded within the Nokia 1390 NPT. For further information on Nokia 1390 NTP, refer to the latest Nokia 1390 Network Planning Tool (NPT) User Guide. Note: The 1830 Engineering and Planning (EPT) tool should be used to design the equipment and commissioning data for the network. It is important that traffic is entered into the EPT design before the network design is complete and before the commissioning file is created, as traffic type and amount affects choices such as inclusion of the optional egress Line Driver, DCM Type, power targets for the Software Control of Transmission (SCOT), and so on. In particular, factors such as the type of Optical Transponder (OT), whether alien optics interfaces would be used, and whether OPS protection is needed for demands in the future should be considered at design time. New traffic designs can be added after the network is deployed, but may require power adjustments, equipment additions, or equipment type changes. Equipment additions and type changes may be service affecting. Purpose of the 1830 PSS EPT
The EPT is used for network planning, design, installation and commissioning as described in this section. Network Planning (Customer Capacity Planning Organizations, Customer Route Planners, Customer and Nokia Network Designers)

EPT Features in Release 9.0
....................................................................................................................................................................................................................................
EPT Features in Release 9.0 PSS-24x Support including 2UC400-compatible, 4UC400-compatible and 130SCUPH-compatible and 2UC400-compatible and 4UC400-compatible Support for FOADMs

Support 1830 PSS-24x 10T Switched DWDM Shelf. These are switching shelves that are not compatible with today’s 1830 I/O packs. From the NE’s perspective, the PSS-24x is a shelf that can be intermingled with other shelf types (PSS8, 32, 16II and even 16). It can be located in the same rack as another PSS-32 shelf, for example. 1390 NPT fully supports the 24X, including BOM, equipment view, and rack placement. The PSS-24x shelves are only allowed as extensions to PSS-32 and PSS-16II master shelves. In R9.0.1, EPT forbids a PSS-8 or a PSS-16 from being a master shelf. Shelf reservations only apply for legal master shelves, the PSS-32 or PSS-16II. EPT does not show the PSS-24x in the Equipment View. The PSS-24x’s are entities residing in separate rack(s). Support signals from the 2UC400-compatible and 4UC400-compatible on the PSS-24x and the 130SCUPH on the PSS-64/-36. The PSS-24x shelf and the 130SCUPH also support signals from the D5X500. Allows 2UC400-compatible and 4UC400-compatible on FOADMs. Some assumptions made for this feature: – PSS-24x shelf is treated by EPT as an OCS shelf, similar to how it handles the PSS-36 and PSS-64. Management of the OCS shelves is the responsibility of 1390 NPT. – EPT currently allows the user to skip shelves, meaning that after the master shelf (always shelf #1), the next sub-shelf could be #2 through #24, and it could be of any type (PSS-8, 16, 16II or 32). So, in this example the PSS-24x could be shelf #3 in the chain of shelves. – Shelf 1 may not be a PSS-24x. EPT does not allow the PSS-24x as a shelf 1 even though the NE supports this. – 1390 NPT provides the shelf and slot number of the uplink cards, which is needed for EPT to put the connecting cables into the BOM and for the Installation Report. EPT restrictions: – EPT does not keep track of PDUs – Jumpers are all custom for the uplink cards – – – –
EPT does not keep track of attenuators. There are only 2 uplink cards from the PSS-24x; neither need an attenuator. EPT does not keep track of PSS-24x shelf covers or rack doors. No BOM support (no fan, no power filters, and so on). EPT does not handle the client cards or the switch EPT does not change how it handles fiber storage trays

– –
EPT does not change EC LAN cable handling EPT does support the signals from the uplink cards (2UC400, 4UC400, and 130SCUPH), but EPT does not carry any other information about them like placement in the PSS-24x shelf, except shelf/slot location.
D5X500 R9.0.1 Feature List OTU4 Client Support
EPT R9.0.1 supports the following pluggables for the D5X500 for all OT modes: • •
C4CLR4d: Supported in R8.2 for D5X500 (10505) client signal types: 100G LAN PHY & OTM-0.4 C4CLR4e: Previously supported on 260SCX2 only (11100 for D5X500 in R9.0.1) client signal types:100G LAN PHY Note: EPT supported OTU4 client signals in R8.2. The NE did not. Note: NE supported C4CLR4e in R8.2. EPT did not. The D5X500 does not support a mix of 100GbE and OTU4 client signal types in the NE. This is not restricted in EPT R8.2. EPT R9.0.1 continues to allow mixing of 100GbE and OTU4 clients on the same D5X500 pack.
New Modulation Formats (QPSK and SPQPSK)
EPT supports two new modulation formats (OT Modes) for the D5X500 in R9.0.1: • •
QPSK (Mode 3) SPQPSK (Mode 4)
Both modulation formats support only OTU4 line rates for a total line rate of 260G for the OT. In R9.0.1, the modulation format used on the L1 and L2 ports are the same. A new line type is supported in R9.0.1 for the D5X500. Line ports now support: •
OTU4x2 (used only for 8QAM, 16QAM, and 8QAM-SC)
•
OTU4 (new – used only for QPSK and SPQPSK)
In R9.0.1, the line type used on the L1 and L2 ports are the same. Client Port Mapping
The D5X500 in R9.0.1 support a fixed client port to line port mapping. When the port type is set to OTU4x2, it sets up the following fixed transmission paths inside the card: • •
Signals from client port C1 and client port C2 are sent to L1. Signals from client port C3 and client port C4 are sent to L2.
•
Client port C5 is not used.

When the port type is set to OTU4, it sets up the following fixed transmission paths inside the card: • • •
The signal from client port C1 is sent to L1. The signal from client port C3 is sent to L2. Client ports C2, C4, and C5 are not used.
Protection, GMPLS, FEC
Protection types supported: • • • • •
Unprotected Diverse Path Dual Homed Y-Cable OPS Single Interface (GMPLS disabled, not Configurations D/D’/D”)
All D5X500 OT modes are supported in GMPLS networks in R9.0.1. All OT modes support the SDFEC-G2 FEC type. D5X500 PSS shelves
The NE supports the D5X500 in the following shelves: • • •
PSS-32 PSS-16II PSS-8
All OT modes are supported in the 3 above shelf types. (EPT has supported all 3 shelf types since R8.2). Unidirectional Regeneration
Since the D5X500 has two line ports, unidirectional regeneration should be supported with a single D5X500 OT. The D5X500 may also be used as a 3R regeneration in GMPLS networks. The regeneration can be any OT mode, but only support regeneration of signals using the same OT mode. Photonic Line Support on CDC-F and C-F
The D5X500 when configured with a modulation format of 8QAM,16QAM, QPSK or SPQPSK support the following node configurations: • •
CDC-F C-F (former AC-D-C)
•
C-F Add/Drop Block as a separate NE connected to a WR8-88AF in a different site
EPT does not restrict the usage of the D5X500 with any modulation format in these configurations. ....................................................................................................................................................................................................................................

Node Scalability
Single-site/multi-node (NE) clusters provide flexible and scalable growth options: • • • •
• • •
Multiple independent 1830 NEs participate in a “cluster” arrangement NEs with SWDM optical line resources (Optical Node NEs) perform auto power management for OT line ports on other SWDM NEs (OT NEs) Flexible mixing of Optical Node and OT NEs (OCS Tributary NEs can be connected to Optical Node NEs as well in a “cluster” fashion from some releases) Supported shelves from Optical Node and OT NEs: – Main shelves: PSS-32, PSS-16II (equipped with 32EC2) – Extension shelves: : PSS-32, PSS-16II, PSS-16, PSS-8, PSS-24X Each 24-shelf maximum size NE is managed separately, via its own management interface All the cluster NEs at a location should be directly cabled together in circular daisy chain fashion WLT on and auto power-managed lines only
Single Blade with WR20 as DGE
The single WR20-TFM DGE uses only one WR20-TFM card instead of two to equalize channels. The WR20-TFM card contains two WSSs. One WSS is used per direction of transmission. The WR20-TFM DGE node is comprised of the following cards: • •
Line drivers, ingress and egress for each degree A single WR20-TFM
The following cards provide monitoring and diagnostic functions: WTOCMA or WTOCM-F card can monitor up to two degrees. Additional cards, such as OTDR and RA2P, can also be used with this DGE node. Special breakout cables, providing fiber connectivity between MPO ports on the WR20-TFM and LD ports, are also used. To connect the WR20-TFM to the line amps, a special MPO-LC breakout fiber is required. It is a unique simplex 2.3m length cable with two APNs for EIA/ANSI and ETSI shelves. On Network Parameter/Site/Multiple Site windows, a new option for single blade DGE is displayed, which is used by auto-design to select which type of DGE should be created. New option of possible DGE type is extended also in Node Detail panel.

Upgrading the node to an OADM node would require service interruption and re-configuration of the node. NE software routes channels through from an incoming degree to the exit degree as individual channels. Colorless IROADM for Add/Drop All Coherent Channels
This functionality extends the support of IROADM to carry coherent channels, bypassing the fixed grid SFDs. The configuration connects the add/drop ports of the IROADM to the PSC1-6, supporting up to 18 coherent OTs per direction (36 OTs total) in a two-dimensional IROADM system. The new IROADM configuration is a PSC (IROADM+PSC): “pure” colorless IROADM configuration, only PSCs are attached. It is valid in R9.0.1 to have a composite CLS IROADM with a PSC on one optical line and SFD on another. The restriction is that the same IROADM degree cannot have PSC and SFD together on it as described in GMPLS L0 CP Support for Metro Applications CLS IROADMs; this is not supported in GMPLS. Flex Grid Phase 1, PM-8QAM and SPQPSK signals permitted through WR8-88AF ROADM lines in DWDM-FLEX links
This feature refers to the second part of Phase 1 (the first part was in Release 8.2). In Release 9.0.1 the signals that this applies to are: •
D5X500 OT PM-8QAM and SPQPSK mode (modulation) signals
•
2UC400 “off shelf uplink card” as a 2UC400-compatible, PM-8QAM and SPQPSK modes
InRelease 9.0.1 the PM-8QAM/SPQPSK modulation format signals are 62.5GHz wide and correspond to the following modes on the Trail/Services window: •
PM-8QAM (introduced in Release 8.2)
•
SPQPSK (introduced in Release 9.0.1)
This functionality has the following dependencies: 1. DWDM-FLEX Link support between WR20-TFM ROADM and WR8-88AF ROADM 2. SPQPSK on the D5X500 3. SPQPSK and PM-8QAM on the 2UC400-compatible signal PM-8QAM and SPQPSK mode signal routing is enhanced to allow routing through the WR8-88AF ROADM lines, on DWDM-FLEX link types only. This signal is not permitted to add or drop on the WR8-88A ROADM lines (even for regeneration). ....................................................................................................................................................................................................................................

Introduction
EPT Features in Release 9.0
....................................................................................................................................................................................................................................
In Release 9.0.1 EPT retains the restriction that WR20-TFM and WR20-TF ROADMs are only permitted in DCM-free (or externally verified) networks. Channel Adjacency Restriction: The routing of these signals in Release 9.0.1 requires that neighboring channels, 50 GHz from the center channel used for the route, are unused for the length of the route. The routing of trails using these OT/Mode combinations are available in GMPLS-enabled and disabled networks, on: 1. DWDM-FLEX EPT Link types, given the channel adjacency restriction above, with the following endpoint nodes: •
WR20-TF/M ROADMs or WR20-TF/M ROADM (DGE)* (EPT R.2.2) (as already supported in previously releases): Add/drop, Thru, Regen • WR8-88AF ROADM lines (Release 9.0.1) - Through only 2. DWDM-100GHz EPT Link Types on CWR8/CWR8B TOADMs support add/drop, through and regen (EPT R.2.2 The EPT DWDM-FLEX links above may have ILAs or GlassThroughs (splices) in them. *In the above, ROADM (DGE) refers to a ROADM with the Optimized as DGE flag set or the new Release 9.0.1 single WR20-TFM card DGE. This functionality also has an implication/restriction for the routing of ordinary 50 GHz wide signals on a DWDM-FLEX link: these signals must be designed only within 100 GHz of the center frequency of a PM-8QAM/SPQPSK 62.5 GHz routed channel. EPT does not require a separate width parameter (75 GHz or 62.5 GHz). EPT: • • •
restricts adjacent channels in the design, designs FLEX equipment on the routes (or alter/restrict route paths), designs FLEX Link types (or alter/restrict route paths)
as required for the width of the signal it is designing. In Release 9.0.1 the center frequencies remain the same as in previous releases, for all link types. R9.0.1 Interworking Configurations

This group contains new interworking requirements for 1UD200 and 130SCUPCcompatible. D5X500 Cascading
EPT R9.0.1 supports a D5X500 cascaded with a 112SDX11 OT. The D5X500 uses the dual rate pluggable (C4CLR4d) on the client port for cascaded OT configurations. Up to 4 112SDX11 OTs can be cascaded onto a single D5X500 OT in PM-8QAM or PM-16QAM mode. A maximum of two 112SDX11 OTs can be cascaded using QPSK or SPQPSK modes. Note: Although the 112SDX11 is not a coherent OT, it can be used in DCU Free networks as a cascaded OT because it is not line facing. PSS-24X OTs
These configurations are covered by the functionalities described in “PSS-24x Support including 2UC400-compatible, 4UC400-compatible and 130SCUPH-compatible and 2UC400-compatible and 4UC400-compatible Support for FOADMs” (p. 1-4).

Figure 1-1 Interworking between CDC ROADMs and Legacy
In Figure 1-1, “Interworking between CDC ROADMs and Legacy ” (p. 1-13), NE1 and NE2 are in separate EPT Sites. EPT auto-design does not automatically add additional WR20-TFM ROADMs. Attenuation might be needed between the two ROADMs to: •
prevent overloading the input to the ingress amplifier in the CDC-F ROADM if the WR8-88A(F) ROADM uses an egress amplifier.
•
prevent OSC overload, even if the WR8-88A(F) ROADM does not have an egress amplifier.

EPT models this (for submarine link configurations) as a DWDM-FLEX or DWDM-50GHz Link type, with no OSC, between two WR20-TF ROADMs (no restriction on ROADM degree count is enforced by EPT). EPT does not support a special flag for this link to indicate it is a submarine link. GMPLS L0 CP Support for Metro Applications CLS IROADMs
•
In GMPLS designs: support only ROADMs with the exception of 1621SLE Link (ROADM + DFOADM in the same NE)
•
Support interworking with legacy ROADM configurations (D,D’,D”) and CDC-F nodes. – AC-D-C (C-F) nodes are not currently supported in GMPLS by both NE and EPT – Support PSS-32,PSS-16,PSS-8,PSS16-II as master and extension shelves – – –
Support of colored directional architecture (SFDs) architecture (No PSCs) in IROADM nodes. Support of single matrix per node: mixed node WR-xx/IROADM is not supported Resource Administrative coloring is still not yet supported by EPT.
In R9.0.1 EPT GMPLS designs support only one IROADM architecture: the one that foresees add/drop using SFD filters connected via ITL unit. Client/Line are supported by GMPLS in GMPLS designs assuming that trails that are part of a ring cannot be neither protected nor restorable. .--- Trails should also be manually routed otherwise we will not show them create ring option. Trails that do not satisfy requirements above are not added to a ring. Modifications of trails in such a way that the above requirements are not satisfy cause the removal of the trail from the ring and also the removal of the route. 4UC400-compatible and 130SCUPH-compatible cannot be regenerated in GMPS designs. The conversion from non-GMPLS to GMPLS design is not done in case a design contains IROADMs with PSC1-6 add drop blocks.

Commissioning File Interface with CPB App within OMS
The Commissioning File Interface in R9.0.1 is a new format and the interface is with the new CPB App within OMS Release 14. The old Commissioning File Interface with the old standalone CPB or older versions of the OMS releases is no longer supported. Upload Application from OMS (Without Upload of Trails and Services)
In R9.0.1 discrepancy reports are supported, while the Traffic Upload is not (it will return in R9.1). GMPLS Support of Network Evolution (Supporting Projects)
Support of network evolution – only Current and Deployed projects are supported in GMPLS designs (not Future). Projects allow incremental or phased design and growth of an installed network’s design. Highlights: • •
Restoration routing is project-less (it is always calculated on whole design) Restoration regenerators can be deleted – Only restoration regenerators in the current project can be removed if not used in a nominal path – Deleting deployed regenerators is not allowed
•
Restoration regenerators can be un-deployed – All restoration regenerators can be removed from a deployed project. They are automatically placed back in the current project. – Nominal regenerators can be removed only by removing trail (or its routing)
Greenfield: •
• •
Nominal regenerators are placed by EPT GMPLS Engine as part of the automatic routing of a trail as well as by manual routing, restoration regenerators are created by a dedicated panel on a given NE. Restoration regenerators can be created automatically by EPT GMPLS Engine, in addition to creation by the panel. User-defined regenerators are reused by EPT GMPLS Engine as much as possible on both nominal and/or restoration routes Only restoration regenerators can be manually removed from the design
Brownfield: Run design options 1 and 2 preserve regenerators placed by user and try to reuse deployed regenerators. Option 3 will remove user-defined regenerators if not deployed or used. EPT GMPLS Engine can use a user-defined restoration 3R that is optically compatible with a trail, even if the 3R is not the pack that EPT GMPLS Engine would place by default. ....................................................................................................................................................................................................................................

Upgrade EPT Design from Non-GMRE to GMRE and Vice Versa
The EPT supports a network design upgrade from non-GMRE to GMRE and downgrade from GMRE to non-GMRE. A new Convert Design option on the Action menu will convert the design to GMRE or non-GMRE depending on the current design. The EPT will check that configurations are valid before doing the conversion. It is strongly recommended to perform a backup of the of the original file before applying a non-GMPLS to GMPLS (and vice versa) conversion. Channels already assigned don’t move. New channels are added using current channel assignment plan (not necessarily the one that was used before the upgrade/downgrade). An upgraded design may not follow the GMPLS channel plan. The design state will change to “Incomplete” and the user are prompted to execute a Run Design with option 2 recommended (see Step 1). As new trails are added to the GMPLS design, Run Design option 2 will need to be done to recalculate restoration and feasibility. For a detailed list of prerequisites to converting a design to or from GMPLS, refer to “Prerequisites When Upgrading From non-GMPLS to GMPLS” (p. 10-24) and “Prerequisites When Downgrading From GMPLS to non-GMPLS” (p. 10-26). Allow Mixing of Standard Noise OT’s on Colored Ports, While Also Supporting Enhanced OT’s on Colorless Ports
EPT R9.0.1 allows the mixing of OTs as follows: •
Any mix of OTs (Standard OT, Low Noise OT, No Noise OT) can be placed on the colored ports (SFD) of a configuration D, D’’, D‘, ROADM, IROADM with SFD, and TOADM.
•
Only OT of Noise Class coherent with choice set in Network Parameter “Amplified OT Usage” can be placed on the colorless ports of the configuration D, D’, D’‘ ROADM. “Amplified OT Usage” does not apply to the colorless ports of the TOADM because only No Noise OTs are allowed in regular TOADMs.
•
The e-rules for these No Noise and Low Noise OTs are not degraded by the presence of the standard OTs in the colored ports.
•
Allow mixing of Standard noise OTs on colored ports do not apply to IROADM with PSC, CDC-F, C-F node types because they do not have SFD colored ports.
This functionality is not applicable to GMPLS in R9.0.1. Merging Two EPT Files in a Single File
EPT allows the merge of a second EPT design file into an open EPT file (primary file). The two files to be merged must be created using the same build number as the installation of EPT. Older files must be opened and saved to update the build number for that design.

In some optical nodes and network design situation is possible to avoid any optical attenuation or deploy a Fixed Attenuator LBO. This attenuator is remarked via a specific message following an automatic power level check. In the BOM is reported the ATTEN-TBD (Attenuator value TBD upon Link Test) item. The Create Trail window contains the parameter “DWDM Line Pluggable,” which has the new option XL-64TCWint, with the same BOM acronym, description, and APN. In case of the Fixed (that is, nothing or ATTEN-TBD) attenuator preference, EPT provides the best solution looking at the Nodal configuration and related matrix in Figure 1-3, “Nodal Configuration Matrix” (p. 1-18) and some warning messages. Figure 1-3 Nodal Configuration Matrix
Note: Electronic, variable = sVOA in the BOM Fixed = nothing or ATTEN-TBD in the BOM LBO=Line Build Out, also called an attenuator (ATTEN-TBD in the BOM) EPT Support for Designs with Nodes and Trails that Mix Unamplified and Amplified Spans
This feature updates the power setting of channels propagating over unamplified spans. Current power setting forces all the channels to be launched into the fiber at a the same optical power (flat power spectrum), thus most of the channels are attenuated to the power of the channel with the lower power value. This constraint is needed when optical amplifiers are present to regulate the power divergence. However, channels running over unamplified spans can run at a higher power setting. ....................................................................................................................................................................................................................................

Node Renaming and Synchronization
This feature allows a node that is renamed by NPT to retain its name in EPT after Line Design. Run Design option 2 (see Step 1) will keep NE names and SID that have been modified by EPT or NPT (also for Network Element in "Auto" status). Node names for nodes in "Auto" status are calculated by Run Design option 2 and 3 based on the new NE name. A network element is treated as “user modified” if NPT or a user changes NE attributes that need to be preserved. A “user modified” NE will not be deleted when the user or NPT removes auto-designed equipment (Run Design option 2). If the user or NPT forces the NE to be deleted by doing a run design with removing both user and auto-designed equipment (Run Design option 3), shelf reservations and other saved NE attributes are deleted. Removal of Virtual Demands in EPT
From EPT R9.0.1 on, virtual demands are no longer supported. Upon opening an EPT design file that contains virtual demands, an error message is displayed and the EPT design is not loaded or imported. You must remove the virtual demands using a previous release of EPT. Removal of PSS-1 Support
From EPT R9.0.1 PSS-1 is no longer supported. Upon opening an EPT design file that contains a PSS-1 NE, an error message is displayed and the EPT design is not loaded or imported. You must remove the PSS-1 using a previous release of EPT. Removal of 130SNQ10
From EPT R9.0.1, the 130SNQ10 OT is no longer supported. Upon opening an EPT design file if the source or destination OT for any trail is 130SNQ10, an error message is displayed and the EPT design is not loaded or imported. You must modify the OT type or remove the trail with the 130SNQ10 using a previous release of EPT. EPT support of Windows Server 2012

Software Upgrade to Release 9.0
....................................................................................................................................................................................................................................
Software Upgrade to Release 9.0 EPT Software Upgrade to Release 9.0
EPT software upgrade to Release 9.0 is supported from any EPT release subsequent to and including R3.6.50. You cannot move a design from Release 9.0 to Release 6.0.6 or any other previous release. For additional software upgrade considerations, please refer to the 1830 PSS Engineering and Planning Tool Customer Release Notes for the respective EPT release. EPT Design Migration to Future Releases
The following are software considerations when upgrading to EPT Release 9.0 from previous EPT releases. Designs created with previous EPT releases opened in EPT Release 9.0 will initialize new Release 9.0 field parameters to their default values. Note additional upgrading considerations for your EPT software release in the sections below. EPT Release 9.0 Designs
A design cannot be upgraded when it contains deployed site(s) with “CDC-F Special” field value of Shelf placement in Rack or Pack placement in Shelf or if the design has the Integrated Bay field enabled. You must return to the old release to change these values. Note: This will/may change the rack layout of the deployed racks. Due to the removal of the CDC-F network design concept, the following additional changes are implemented: •
•
•
•
Upgrade of a CDC-F network design to Release 9.0 should default the Network Parameters and Site Equipment Options tabs, and per shelf NE Details called “PSS-32 ANSI Shelf Installation Kit” = Extra Depth (this corresponds to INSTNAREXT14 in the BOM). Non-CDC-F network design upgrades should retain the value in the EPT design file. The “PSS-32 Shelf Depth” field value to 13-Inch on the Network Parameters Equipment Options tab, Site Details Equipment Definition tab, and the NE Details window (per shelf). Non-CDC-F network designs will retain its value. Non-CDC-F network designs default the CDC-F specific fields “MCS Add/Drop Block auto creation sequence” and “Specialty FOC MPO Jumpers” to their default values. CDC-F network designs created in Release 8.0.0 and earlier will initialize the new “Specialty FOC MPO jumpers” field value to Yes (FOC type).

EPT Installation and Setup
Software Upgrade to Release 9.0
....................................................................................................................................................................................................................................
•
CDC-F network designs created in Release 8.1 or later retain the “Specialty FOC MPO jumpers” field value. New designs starting in R8.1 already default the value to “No” (non-FOC).
•
Field values that were hidden in the old CDC-F design file, and are now supported in the network with WR20-TFM ROADMs, will have the default values for a standard network. Field values that exist in the CDC-F network design file will retain their values after the software release upgrade to Release 9.0.0. Configurable options previously exclusive to CDC-F network designs will now be displayed and set to their proper default settings, which are dependent on the WR preferences at the site, when the design file is opened in Release 9.0.
• •
In the Node Details window, the “Optimize for DGE” field name will change to “DGE Type” with new options. Any part numbers in the reports or price file that were previously displayed with “ALU” in the name will be renamed. Upgrade of GMPLS designs containing 12P120 packs: S-EFEC is not supported in GMPLS designs; therefore if the default OT is a 12P120 with S-EFEC, or if trails with 12P120 on A-End or Z-end and S-EFEC as requested FEC are present, the design cannot be upgraded. You will have to make modifications in the last EPT version used. C4CLR4d client interface name: When opening a design from Release 8.2.2 or earlier, if EPT discovers a D5X500 OT using client pluggable C4CLR4d (part number 3AL82023AA) the client interface name will be automatically changed from 100GBASE-LR4(CFP4) to 100GBASE-LR4-dualrate(CFP4). EPT Release 8.2 Designs
Updates when upgrading from EPT Release 8.1 to Release 8.2: During the design loading file: •
If deployed cards exist in the network design with a “Not Orderable” Nokia Part Number in the Price file, EPT will maintain those cards. A warning message window will be displayed to advise you of this scenario.
•
If undeployed cards exist in the network design with a “Not Orderable” part number in the Price file, you have the option to manually replace these cards with the orderable part number. This includes the 11DPE12A OT card with part number 8DG59340AC, which has been discontinued and substituted with the part number 8DG59340AD. By default EPT changes any un-deployed old card with the new one. A warning message window will be displayed to advise you of this scenario, which will allow you to change the discontinued equipment as desired in the Network Element Details window (see Figure 5-25, “Network Element Details Window” (p. 5-96)).
In addition, in all DWDM links, the Do not auto-design 50 GHz flex-grid channels below field will be set to Use Global Value. ....................................................................................................................................................................................................................................

....................................................................................................................................................................................................................................
When opening a GMPLS design that was created in EPT R3.6.50, R5.n. R6.n or R7.n, with an EPT R8.0 or later release, it is recommended before generating any report, to run the design. Be sure to select the Remove all auto-designed elements option (see Figure 8-1, “Run Design Options Window” (p. 8-5)). 1UD200 Packs: R8.1 designs that have the 1UD200-100G OT change to the 1UD200 100G linerate mode when the design file is first opened in Release 9.0. Equipment Controller (EC) Types: •
EPT will retain the EC type and part number for all current, future, and deployed designed PSS-32 and PSS-16 shelves.
•
New PSS-32 shelves added to the design in Release 8.2 will use the EC type EC if the main shelf (shelf 1) of the NE contains an EC. New PSS-32 shelves added to the design in Release 8.2 will use the EC type 32EC2if the main shelf (shelf 1) of the NE contains a 32EC2.
• •
If this is a redesign or addition of the main shelf (Shelf 1), EPT will use the EC type 32EC2 in a PSS-32 shelf.
EPT Release 8.1 Designs
Updates when upgrading from EPT Release 8.0 to Release 8.1: •
•
•
In CDC-F network designs, the EPT will select the default value of Yes in the Specialty FOC MPO Jumpers field on the Equipment Options tabs of the Network Parameters and Site Details windows. If the design file contains SXS64.2C pluggables, EPT will update the part numbers to remove the “AA” at the end of the string so that the part number is 10 characters in length. If the design file contains pluggables with the name “S10GB-SR(DCI),” EPT will convert them to “S10GB-SR.” This pluggable is only applicable to 112SDX11 and 11OPE8.
Exclusions when upgrading from EPT Release 8.0 to EPT R8.1: • •
EPT Release 8.1 will not upgrade or open an older design file containing a PSS-16II shelf. EPT Release 8.1 will not upgrade or open an older design file containing one or more OMSP links, as they are in an unsupported format. All OMSP links must be removed from the design and recreated in EPT Release 9.0.
For EPT designs created in releases prior to R8.1 and opened in R8.1, EPT will default the new Specialty FOC MPO jumpers field on the Network Parameters and Site Details windows (Equipment Options tab) to use FOC MPO jumpers, because that jumper type is what those networks were using.

•
11STAR1A, 11DPE12E, 11DPM12, 11QPA4, 11QPEN4 no longer support S-EFEC
EPT Release 7.0 Designs
Designs created with EPT Release 7.0.2 will be migrated to EPT Release 7.0.4 as follows: •
New Release 7.0.4 configuration parameters will display their default values.
Designs created with EPT Release 7.0.0 will be migrated to EPT Release 7.0.2 as follows: • •
New Release 7.0.2 configuration parameters will display their default values. High ASE OTs: –
If the design file does not contain any high ASE OTs, the default OT is not a high ASE OT, and OSNRmin attribute of any OT has a non-default value and has format dd.27, then EPT will open the design file in prohibit medium ASE OTs mode. Reset the OSNRmin to its default value.
–
If the design file does not contain any high ASE OTs, the default OT is not a high ASE OT, and OSNRmin attribute has its default value then EPT will open the design file in Allow Mixing mode. If design file has a high ASE OT or high ASE default OT, then EPT will open the design file in Allow Mixing mode. If the OSNRmin attribute of any OT has a non-default value and has the format dd.27, then reset it to the default value.

NOFEC is not supported with the XL-64TCW tunable zero chirp pluggable; if the source or destination OT for any demand is 11QPA4 and the selected XFP is XL-64TCW (tunable zero chirp) and the FEC mode is NOFEC, the EPT design will not be loaded or imported. Either modify the FEC type, modify the pluggable to XL-64TU, or remove the demand using a previous release of EPT. If the older EPT design file contains any 260SCX2 (Muxponder) demands in a GMPLS enabled design, the design will not be loaded or imported because the OT is not supported in GMPLS designs. Modify the OT type or remove the demand with the 260SCX2 (Muxponder) using a previous release of EPT. All EPT designs created prior to Release 7.0.2 will have the Shelf Voltage Floor fields in the Network Parameters and Site Details windows set to 39 by default. Any design files with DCU Free and a mix of coherent and non-coherent OTs will not be loaded or imported. Release 7.0.2 design files will default to the PSS-32 high capacity fans, but designs upgraded from Release 7.0.0 will retain their current values as configured with the PSS-32 FAN Capacity field on the Network Parameters Equipment Options window. Design files from previous releases of EPT with existing WDM demands will be converted to trails or services as follows: –
–
–
Each non-cascaded demand will be converted to new a trail (from Line to Line) and a new service composed of all selected client ports for the demand. The service will be routed over the newly created trail. If an OT has the Allow Sharing field enabled and multiple demands use the same line port on the OT, only a single trail will be created. The services created will all use the same trail. Each cascaded demand will require two trails: one OCh Trail and one Cascaded Trail. The cascaded trail will be routed over the OCh trail. A new service will be created for all client ports for the cascaded OT. In both cases, if no client ports are selected, then a service will not be created. If a cascading OT is shared across multiple demands, only a single trail per line port in use is created. No new equipment will be added or removed in the upgrade process. No equipment will change location in a shelf. Trail and Service design states will inherit the design state of the former WDM demand.
EPT Release 6.2.0 Designs
Designs created with EPT Release 6.2.0 will be migrated to EPT Release 9.0 as follows: • •
•
New Release 6.2.0 configuration parameters will display their default values. The names for the High Performance Amplifier choices in the Network Parameters Amplifier Auto-Placement tab have changed in Release 9.0. Upgrading old design files into Release 9.0 map the old names to the new names. If the source or destination OT for any demand is set to 520SCX4-compatible, the EPT design will not be loaded or imported because the OT is not supported. Modify the OT type or remove the demand with the 520SCX4-compatible using a previous release of EPT.

Design Process Workflow 4
Design Process Basic Recommended Design Process
1. Draw all equipment sites. 2. Rename sites with customer names. 3. 4. 5. 6.
Draw the fiber segments between sites. Add the trails and services. Route trails. Route cascaded trails, as applicable.
7. Route services, as applicable. 8. Run the design. Tips: • •
The first two fiber segments drawn at each site will be used as “express paths” for the design. Subsequent fiber segments will be assigned as mesh connections. When in the Add Site mode, press Ctrl and left-click to automatically create a segment connecting the two sites. The first two fiber segments drawn at each site will be used as express paths for the design. Subsequent fiber segments will be assigned mesh connections. This segment will be considered the express path for systems creation (SFD5 and WSS through connections). However, the segment name will be automatically named based on the default site names (for example, siteN-SiteN+1) rather than using a name that has customer meaning.
Design Process Overview and Reference
The EPT supports two methodologies to design 1830 networks: automatic and manual. The automatic design feature is the most efficient way to design most networks, but in certain configurations a manual design is required (see Figure 4-1, “Network Design Flowchart” (p. 4-2)). ...................................................................................................................................................................................................................................

Figure 4-1 Network Design Flowchart
Note: At the beginning of the network design process are several Network Parameters preferences to consider before running the design, although all have defaults. Refer to Chapter 5, “Site and Topology Definition and Configuration”. The following sections describe each step before their detailed procedures. Define Sites
A site contains one or more NEs. The EPT allows you to constrain what types of equipment may be placed at a site. These constraints include: • • • •
the filter architecture (FOADM, ROADM, TOADM) the number of fiber connections (1-8) power limitations (20A, 30A, 50A, 60A or 70A) power feed limit
• •
shelf power margin whether the site environment is subject to the extended temperature range (-40degC/+85degC ), clusters DGE Type preferences ROADM preferences
• • •

• •
Shelf type preferences Equipment Definition (controller and power filter protection options, how to place cards into shelves, shelves into racks, and so on)
Define Topology
This step defines the fiber segment interconnection between sites, and the fiber type and characteristics (or use the defaults). The EPT allows the user to select fiber types (SSMF, LEAF, TW-RS, TWC, TW+, DSF and LS) and specify characteristics of each fiber segment (length, loss, margin, dispersion, and so on). If a segment carries 1588 timing distributed from the PTPCTL card, it is needed to create PTPCTL and PTPIO . Timing Distribution
If a segment carries IEEE 1588v2 timing distribution, the Timing Distribution cards PTPIO, PTPCTL and/or 11DPE12A cards should be added at the Sites at either end of the span manually. Note: At this phase (and until the Run Design command is used), no PTPCTL, no PTPIO physical packs will be created. A different procedure will need to be followed if synchronization is distributed with 11DPE12A acting as controller. Define Traffic Matrix
You can specify a set of trails and services between source and destination sites. Each trail and service defines the following: •
transponder type (such as 11STAR1, 11STAR1A, 11STMM10, 4DPA4, and 43STX4)
• • •
traffic client signal type (such as STM16, 10GbE, and 4G FiberChannel) client interface (such as 10GBASE-LR, S.64-2b, 1000Base-LX) protection options (such as diverse path, Y-Cable, OPS, and ENSCP 1+1)
Design Process
For EPT-enabled automatic design, click Run Design and the optimizer configures the network based on the site, topology and traffic matrix. Automatic design is available for most 1830 network configurations. Define NE Configuration
When performing a manual design, you must create an NE at a site and equip the NE with the appropriate amplifiers and optical filters. This is a two-stage process involving the Create Network Element and Create Node context menu options as follows.

Create Network Element allows you to specify:
•
NE type (1830 PSS or PSS-4)
• • •
first shelf type of the NE shelf width (ANSI 23 inch, EIA 19 Inch, and ETSI) system ID (used by the NE software and management systems)
•
If clustering is enabled (at least one site has Clustered selected) - two additional selections: (Optical Node, Clustered OT Connection)
Create Node supports selection of the following:
•
Optical Node type (ROADM, TOADM, DFOADM, CFOADM, or ECFOADM)
• •
maximum degrees supported on the node ROADM options [pressing the Schematic button displays parameters that support specification of the full set of optical amplifiers (OAs)]
• •
optical filters Dispersion Compensation Modules (DCMs) for up to eight fiber interfaces
Define Link Configuration
The next step in the manual design process is to link multiple optical nodes associated with different NEs or sites into a point to point link. The endpoints of a link are defined to be add/drop sites while intermediate optical nodes in the Link must be either ILA or glass-through sites. Note: An optical channel trail may traverse several links prior to needing regeneration. Four different link types may be defined (100GHz spaced channel link-channel, 50GHz spaced link-channel, CWDM 8-channel [CWDM-1F and CWDM-2F], and Single-channel). Amplifiers and dispersion compensation modules may be specified within the Link Configuration screens (an alternative to specifying them from the Create/Edit Node windows). Amplifier power levels can only be specified from the Manual Details window within the Edit Link window. 1621SLE Links (GMPLS) must be manually designed. Route Traffic
For each trail/service, you can select a path (set of links) for the optical channel trail. Your options include selecting the channel number (or have the EPT automatically assign a channel) and selecting regeneration points along the path.

Evaluate Design
As part of the automatic design process, the Run Design button synthesizes an 1830 network and verifies its design operation. When performing a manual design, click Verify Design to evaluate the design. Errors
After the design evaluation has completed, the EPT will determine if the design is valid or invalid. For invalid designs, check the Design Status report (see Chapter 11, “Reports”) and the Errors tab on the Information Bar (see “Errors” (p. 6-43)). Configure FOC
When measured fiber-optic characterization (FOC) (Loss, Dispersion, and Polarization Dependent Loss [PMD]) is available, the user updates each segment with the measured characteristics. Note: Be sure to verify the margin requirements for both fiber and connectors since many customers assign different margins for estimated versus measured fiber. Reevaluate Design
To determine if the same equipage and power levels remain valid, click Verify Design. If the design elements are not valid, click Run Design or a manual design process to make the necessary changes. Once there are no errors, then generate an updated Bill of Materials and report package. Also there may be system changes if links were deleted during the reevaluation/redesign process. Generate Commissioning File
A Commissioning File (download file) is necessary to automatically commission an 1830 network using one of the support Network Management systems (1340 INC or 1350 OMS). The losses/power levels associated with the EPT design file must be consistent with what the 1830 NE’s see in the field; otherwise the automated commissioning process will not succeed. The purpose of Commissioning is to: 1. Set the power, gain, loss, tilt, other values and ranges in the network with the designed values. 2. Provision the designed card types and locations. 3. Provision the topological connections between packs for the NE configuration designed. 4. Provision the network configuration, link topology between NEs. 5. If GMPLS is enabled, set the GMPLS data in the network used for quick restoration route calculations. ....................................................................................................................................................................................................................................

Design Process Workflow
Design Process
....................................................................................................................................................................................................................................
After the design is error-free, divide the network into a set of rings or linear systems so the commissioning information may be downloaded to the NMS. This process involves selecting a set of links (from the Links tab on the Information Bar) and selecting Create System from the Context menu. See “Creating a Commissioning File” (p. 9-6) for more
details. For relaxed rules on partitioning the network into commissioning systems, select File > Network Parameters window, then set the Commissioning Mode field to Partial Commissioning. To set strict commissioning system rules resulting in the fewest commissioning systems, leave the setting of Commissioning Mode field at its default value. Import Network Data
The Commissioning and Power Balancing (CPB) tool (part of the 1350 OMS) supports generation of an Export File which can be imported into EPT by selecting Action > Import Network Data. Some configurations are not supported by the Import Network Data feature (see “Import Network Data” (p. 12-1)). For restrictions on the Import Network Data feature, refer to the 1830 PSS Engineering and Planning Tool Customer Release Notes for the respective EPT release. Generate BOM and other Reports
The EPT produces a Bill of Materials file in Excel after the network design has been verified. You may attach pricing to each line item in the BOM or manage the pricing within Excel. Additional reports that describe the network design including fiber data, fiber utilization, circuit pack slot assignment, fibering instructions, and traffic matrix are available as well. See Chapter 11, “Reports” for more details.

Network Parameters Overview
The EPT Design Network Parameters specify global preferences. For parameters that are also supported as a Site Preferences, the Network Parameter value is used as the default when a new site is created. User Preference Profiles and Saved Defaults
The settings in the Network Parameter window tabs can be defaulted to settings on a per-user basis. To open the Network Parameters window, select File > Network Parameters, select the desired values, and click Save As Defaults. Specific designs can override the default values so that when saved, the Global Network Parameters associated with that design is saved. The Save As Defaults operation creates an eptDefaults.xml file that is stored in the EPT installation directory. These customized settings/values are then applied to each new EPT design. To restore the Network Parameters to the factory default, remove this file from the directory. Note: Cost-optimized amplifiers in the Figure 5-7, “Network Parameters Window (Amplifier Auto-Placement Tab)” (p. 5-33) are not saved with this method. The following sections detail the various tabs on the Network Parameters window. View or Edit Network Parameters (Network Parameters and Defaults)

Notes:
1.
Maximum DWDM Channels: The range of allowed values are restricted based on the Maximum DWDM channels. Since the maximum PPC grows as the number of allowed channels decreases. Reach improvements can be realized by reducing the channel count. The link capacity is based on the value of these fields when you run the design.
2.
Dispersion Compensation Modules: If you change this value, routed WDM demands using 43SCA1-compatible, or 43SCX4-AFEC, 112SCA1 and 112SCX10 OTs change to the “Complete, unverified” design state, and a warning is displayed.
3.
Bypass Wavetracker Rules: The field models transmission using internal WaveTracker Detectors (WTD) until the number channels on any link reaches the selected channel count threshold. A warning message is issued if the channel count exceeds the threshold. It is recommended to deploy the WTOCM circuit pack to grow the channel count past this threshold. If deselected, transmission is modeled using the maximum channel count per link.

Notes:
1.
PSS-32 Power Filters/Breakers: For PSS-32 NEs, the EPT will select the 50A power filter if the power consumption of the packs in the shelf is more than 30A and less than or equal to 50A. Selecting 20A forces the 20A power filter to be used unless the current draw exceeds 18A, whereupon a 50A power filter is used. Selecting 30A forces the 30A power filter to be used unless the current draw exceeds 27A, whereupon a 50A PF is used. Selecting a 70A power filter forces the 50A power filter to be used unless current draw exceeds 45A whereupon the 70A power filter is used. If the current draw beyond 63A requires packs to be installed in a separate shelf draw exceeds 27A, then 50A is used until current draw exceeds 45A when the 70A power filter is used. Checking both 30A and 70A power filters results in the 30A power filter to be used until current draw exceeds 27A, then the 50A power filter is used until current draw exceeds 45A when the 70A power filter is used.
2.
For PSS-16, power is chosen based on power consumption of shelf exceeding 90% of the rated power filter. PFDC35K is chosen if power draw is more than 18 Amps.
3.
By default, the EPT picks the PFDC50 power filter type for each PSS-32 shelf (two for every PSS-32 shelf). Each time a pack is added, the resulting sum of power for all the packs in the shelf is verified to be under 50A. If the power is exceeded when adding a pack, then a new shelf is created for the pack.
4.
PSS-4 Power Filters: When the power dissipation exceeds the capacity of the power filter type requested for the PSS-4 shelf, the EPT will add another shelf to the design.
Note: If only the 20A power filter is selected, the EPT will add a second shelf when the current draw on the first shelf exceeds 17.5A. ...................................................................................................................................................................................................

Regen Mode
Applicable for GMPLS networks, for auto-designed regeneration in nominal and restoration paths.
Unrestricted 3R (default): Specifies that a site is available to be selected (unrestricted) based on the standard algorithm for auto-regen placement when considering this site.
Note: Regarding the Favor 3R value, consider that the total number of regenerators in the network could increase or change (reduced), based on sharing optimization interaction with favored sites. Therefore we recommend this value only expert users to use this value; some experimentation with this may be needed to confirm that results are acceptable.
Favor 3R: Specifies this site as “favored” for auto-designed regen placement (for restoration and nominal paths). If the auto-design function needs to place a regenerator along a restoration or nominal path, it will choose a favored site to place it, if that does not cause the total number of regenerators to increase along the path. If there are several favored sites to choose from, the EPT will pick one that will to minimize “cost” in the design, where cost is a multipart criteria including the least number of regenerators for the design, best performance (feasibility) and other factors. There is a small cost subtracted if the site is favored (if chosen over an unrestricted site which would have been chosen). If there is an existing regen that the path can use, it may not add a regen to the favored site, but instead share the regen. Forbid 3R: Specifies the site as “forbidden” for auto-regen placement (for restoration and nominal paths). The auto-design function will never place a regen at this site, even the design fails. Manual regens for nominal paths can be placed at this site.

Notes:
1.
OADM Main Shelf: When both PSS-32 and PSS-16 are checked, the EPT will place the solution that can meet the maximum degree requested, with the fewest blank slots. The solution is based on the packs and configuration requested, and the rules of what elements are allowed to be placed in each shelf type. In addition, each time Run Design is selected, the current autonomous design is deleted, and the first shelf type of auto-configured NEs in the current project at this site may change, based on the current line, link and demand configurations. However, the first shelf type of user-configured NEs will not change.
2.
Extension General Use: The NE Details has this same field and defaults to the values set above, at the time the NE is created. When ILA extension shelves are automatically added, will default to be the same type as the main shelf. When they are added manually, they will follow the same rules as an OADM. ILAs can need more than one PSS-8, PSS-16/PSS-16II main shelf if they have Raman/WTOCM/OTDR and use separate cards per degree.

Long Haul WaveTracker Decoder (WTOCM) Usage: Changing the value on the Network Parameters window affects segments only in the current project (see Table 5-1, “Network Parameters Window (Network Parameters and Defaults Tab)” (p. 5-5)).
4.
Changing the Capacity or Long Haul WaveTracker Decoder (WTOCM) Usage removes the WDM link using that segment (which also removes the routing of any trail using the segment). Link editing or right-clicking on links in the Links table (see Figure 6-9, “Links List” (p. 6-24)) allows you to change the WTOCM setting without removing the WDM link.

When line protection creation is successful, selecting the primary path on the map highlights it in red, and selecting the secondary path on the map highlights it in blue. Note: You can also create line protection by selecting contiguous segments on the network map. In addition, to create a valid path, the following criteria must be met: • • •
The Primary and Secondary paths must use a disjoint set of segments. The Primary and Secondary paths must start and end on the same site. One path (primary or secondary) may not have the same site between segments occurring more than once (that is, no loops). The same site is permitted to occur on both the primary and secondary paths.
• •
The segments cannot contain previously-configured links. The segments have the same value for WTOCM Type (either WTOCMx or WTD(no WTOCMx)).

Allowed Values {Comma-separated list of shelf numbers} Note: The number 1 is not a valid value since a PSS-24x may not be the master shelf.
Shelf numbers may be persistent. Reservations are preserved unless the NE is deleted. NE attributes such as Name and Shelf Number will be ‘user-defined’ so that they will persist through Run Design option 2. Note: All shelf reservations are triggered from an EPT or NPT user operation. Thus, once a shelf is reserved, the NE is considered user-defined. Run Design option 3 will remove all reservations, but Run Design option 2 will not remove reservations because an NE with some reserved shelves is user-defined (see Step 1). Optical Node

Links Before you begin
Before you can create a link on a site, you must first configure an appropriate NE for the kind of link you want at each site (see Chapter 5, “Site and Topology Definition and Configuration”) and a segment between them (see “Create Segments” (p. 5-78)). Observe the following rules before you begin configuring links for your network design: •
DWDM links are supported on ROADM, TOADM and DFOADM nodes. The EPT can design either 44- (100 GHz) or 88-channel (50 GHz) links. You can configure the link capacity by editing the capacities of the individual segments on each link. To configure only the odd-numbered 44 channels associated with the SFD44B, you must use a manual design. 88-channel (50-GHz) links must use TOADM filters at pass-through sites. FOADM configurations are supported for point-to-point connections only, and must use SFD40/SFD40B or SFD44/SFD44B filters. DWDM links are also supported at the intersection of the set of the WTOCMx supported at either end of the link.
•
CWDM links are supported on CFOADM and ECFOADM nodes. CFOADM can terminate/originate CWDM links with ECFOADM. CFOADM-to-CFOADM CWDM links are supported.
•
Single Channel links are supported on TOADM, DFOADM, CFOADM, and ECFOADM nodes.
Some tips when configuring links are as follows: • •
Set power levels based on link loss – Amplifier gain is 2 to 3 dB higher than the fiber loss for ILAs Dispersion map requires using 30KM DCM on egress amp for [SSMF] G.652 fiber whenever the fiber length is greater than 30 km. When selecting an amplifier, consider: – Flat gain region and minimal power input of the amplifier – Small channel count and Booster Amp (only increases OSC reach)
Create DWDM Links
Perform the steps in the following procedure to create a DWDM link and configure OAs or DCMs.

Create OMSP DWDM 50 or 100 GHz Link
EPT supports Diverse path and Dual Homed Protection over OMSP links (ROADM and DFOADM). OMSP unidirectional non-revertive protection adds support for ROADM nodes and WR8-88A, WR8-88AF and WR2-88 cards on PSS-16 and PSS-32 (see additional considerations in “OMSP Considerations” (p. 6-30)). ...................................................................................................................................................................................................
1
Before you can create an OMSP DWDM 50 or 100 GHz link, you must first: 1. Configure Line Protection between the A-end Site and at least one other site in the network with segments that support DWDM 50 or 100 GHz links (see “Configuring Segments for OMSP Link Primary and Secondary Paths” (p. 5-86)). 2. Create an NE with the following node provisioning: • In the Max Degree field, select 5. •
In the Max AnyDir Add/Drop Blocks, field, select 0.
...................................................................................................................................................................................................
2
Do one of the following: • •
Right-click on a source site and select Create OMSP_DWDM-50GHz Link, and select the OMSP link start endpoint NE and the node. Right-click on a source site and select Create OMSP_DWDM-100GHz Link, and select the OMSP link start endpoint NE, the node, and Line Protection identifier.
...................................................................................................................................................................................................

OMSP Considerations
OMSP unidirectional non-revertive protection is supported on DFOADM and ROADM nodes when Wavelength Tracker is enabled. OMSP is not supported in CDC-F or GMPLS networks. OMSP is supported on PSS-16 and PSS-32 on the following OTs: 112SCX10, 130SCX10, 11DPM12, 11QPA4, 11QPEN4, 11STAR1, 11STMM10, WR2-88, WR8-88A and WR8-88AF. This includes ROADMs at the endpoints of the OMSP link and ROADM DGEs within the OMSP link. Only the following LDs are supported on OMS protected by OMSP: •
Ingress: ALPHG, AHPHG, AHPLG
•
Egress: None, ALPHG, AHPHG, AHPLG, A2325A
A ROADM supports up to 5 OMS protected links (that is, 10 bidirectional OSPF interfaces). MESH4 cards are not supported in the endpoint ROADMs of an OMSP. IROADMx cards are not supported in OMSP. All DWDM filters are supported in case of OMSP protection: •
SFD5 (supported also in cascaded configuration)
• • •
SFD8 (supported also in cascaded configuration) SFD40/40B (+ITLB) SFD44/44B (+ITLB)
Each OMS protected path may contain 0 or more ILAs and/or DGEs. Linear, mesh and ring network configurations are supported. The two paths of an OMSP link must be link diverse (that is, they must have no shared links). The two paths are not required to be Site diverse or NE diverse (for example, if there are two DGE nodes in one NE at a site, then one DGE could be in one path and the other DGE in the alternate path of an OMSP link). ROADM mesh and thru connections are only supported in a ROADM with OMSP protected optical line configurations provided that both optical lines that are involved in the mesh or thru connection are configured for OMSP. Any channel that is routed between an OMSP ROADM optical line and a non-OMSP protected ROADM optical line will be regenerated between the optically disjoint ROADM nodes within the same NE. Trail routing in the map will display the routing via both physical links included in OMSP link. Routes inside manual routing panel includes both WDM links and OMSP links.

Modifying WTOCM Usage
OMSP supports WTOCMx cards and Wavelenth Tracker Detection (WTD) monitoring. Since all optical line in a node must be with WTOCMx card or all without, the two OMSP links with the ROADM or FOADM endpoint nodes must be provisioned the same.

WSS Overhead Error
When designing FOADM networks, power deviation is the prime source of concern for keeping costs down. Once the power deviation exceeds 4 dB (or 6 dB when TOADM compatibility is removed), then additional CWR8 devices are required. The WSS Overhead error condition indicates that the power divergence (ripple) seen by the CWR8 exceeds the maximum that this device can correct (4 dB). To address the WSS overhead problem, find the source of excessive power divergence: ...................................................................................................................................................................................................

Verify that no amplifiers are operating outside the standard gain range. Additional ripple is introduced as the gain enters the extended gain region (see Figure 6-28, “WSS Overhead” (p. 6-46)).

The standard gain ranges for amplifiers is as follows: • • • •
AM2032A: {26-40} A2325A, A2P2125, AHPHG, AHPLG, AM2125A, AM2125B: {15-31} AM2318A: {7-24} AM2625A: {16-30}

The EPT often selects an AHPLG pack to improve the Noise Figure (NF) and reduce the OSNR at the expense of power divergence. Modify the amplifier selection. ...................................................................................................................................................................................................
3
Reduce the target output power of the amplifier to reduce amplifier gain and result in less ripple. (This also trades off NF and power divergence.) ...................................................................................................................................................................................................
4
Add a RA3P amplifier to reduce gain for long spans (at significant cost–and the RA3P amplifier adds additional power divergence). ...................................................................................................................................................................................................
5
Typically the EPT can support 5 ILA spans. If a design has more than 5 spans without a CWR to balance power, this may be the cause of ripple. Add a CWR.

Using the Physical Layer Report, find the amplifers that are operating outside the standard gain region under the oaname and gain columns. This will reduce the linear ripple contribution (as shown in the lin rip column) of each amplifier to approximately 0.75 dB per amplifier (see Figure 6-29, “Physical Layer Report” (p. 6-47)). Figure 6-29 Physical Layer Report
Result: After changing the amplifiers, the cumulative linear ripple (as shown in the
cum lin rip column) drops from 4.76 dB at Walker to 3.32 dB. This is sufficient for the overall design to verify without any errors.

You can clear this condition by configuring the network to use Wavelength Tracker Long Haul (WT-LH). The WT-LH technology is embedded in the WTOCM card. This card calibrates the Wavelength Tracker for high power, long span, and long path applications. In metro regional applications, the calibration offered by the WT-LH technology is typically not needed.

You can address the RAMAN tilt problem by reducing the amplifier output power. In the following example uses an 11x19dB linear network (11 spans, 19 dB/span fiber loss, 0 dB margin, 0 dB connector loss) to illustrate how to correct a moderate excursion of the RAMAN tilt by reducing the amplifier output powers. 1. Click WDM on the Information tab. Check the Src OSNR Margin value (it should be at least 1 dB).

2. Examine each link to determine if the EPT has chosen the most appropriate set of amplifiers. In this case, adding an egress amplifier increases both the OSNR (desirable) and the RAMAN tilt (undesirable).
3. The large RAMAN tilt (9.63 dB) corresponds to a NPS = 0.505617 rad (as shown on the Physical Layer report). This corresponds to an integrated power of ~13 dB. The WT integrated power limit is approximately 8 dB. Therefore, you can start reducing the output power of the amplifiers by approximately 5 dB (3.57 – 5 = -1.43 dB). By trial and error, you an increase power to approximately -1.25 to -1.2, as shown in the working design below.
Note: To maximize the OSNR, use the ALPHG amp whenever the output power is less than or equal to 0.57 dBm and the amplifier gain is greater than 19 dB.

Using the same 11x19dB network in the example above, you can address the RAMAN tilt problem using the Bypassing the WaveTracker Rules method. 1. Set the Maximum Number of Channels Before WT-LH value on the Auto Design and Verification tab of the Network Parameters window. and then simulate the network. Using our previous example yields a working design at 26 channels (WSS overhead errors require correction as described in “WSS Overhead Error” (p. 6-45)). However, this approach yields a much higher OSNR, making it more suitable for 40G traffic. Additionally, much longer designs can be supported using this technique. The example below shows a 24x19dB design that is enabled by bypassing the WT rules after the 1st ten channels are equipped.

The following lines require the minimum # chans
“The following lines requires the minimum # chans” warning is displayed for certain designs after the Run Design or Verify Design process is completed. This warning means that possible traffic patterns exist that may require more than one channel present on the link to maintain the minimum power on an ingress amplifier . The EPT determines if a minimum power warning is necessary by examining all possible traffic patterns and verifying that the nominal power minus any power ripple exceeds the amplifier minimal power requirement. If you receive this message but no errors are displayed in the Error Information Bar, there is no pending issue. ...................................................................................................................................................................................................

To determine exactly which traffic demand is causing this phenomenon, create an any-to-any traffic matrix, simulate the design and check the Error Information Bar or the Physical Layer Report for power levels less than -32.8 dBm [for AHPHG or ALPHG packs] or less than -24 dBm [for AHPLG packs].

Trails and Services Process
This section describes the process to configure and route trails and services (formerly WDM demands) as follows: 1. Configure trails and services as desired (see “Create Trail” (p. 7-4) and “Create Service” (p. 7-14)). 2. Route trails, as applicable (see “Route a Trail” (p. 7-20)). 3. Route cascaded trails, as applicable (see “Route Cascaded Trail” (p. 7-28)). 4. Route OT-to-OT trail connections, as applicable (see “Create OT-to-OT Trail Connection” (p. 7-13)). 5. Route services, as applicable (see “Route Service on a Trail” (p. 7-30)). You cannot route a service over a non-routed trail. If you are including both trails and services in your network design, see “Simultaneous Trail and Service Configuration” (p. 7-4). Simultaneous Trail and Service Configuration
You can create a service without creating a trail first. To create all parts of a demand in a single step, create a service (see “Create Service” (p. 7-14)), select New in the Primary Trail field, and leave the default values for the new trail. Create Trail

Figure 7-7 Trail Routing Window (GMPLS Designs)
The trail routing for GMPLS networks shows in both directions for each link supporting the trail the percentage of the following optical parameters as percentages, from left to right: •
osnr%: Displays the fraction of the OSNR budget of the route consumed.
• • •
nlp%: Displays the fraction of the NLP budget consumed. pmd%: Displays the fraction of the PMD budget consumed. WssCount%: Displays the fraction of the WSSs consumed.
Two sets of values are depicted on each span within arrows that indicate the transmission direction for which they apply. The values represent the budgets consumed for transmission from the head end to the end of that span. Acceptable values are shown in green. Values greater than 100% are displayed in red to indicate that the budget for that parameter has been exhausted and regeneration is needed. Note: If the route is protected, a window is displayed that allows you to change this setting. ...................................................................................................................................................................................................

The Site Selection window allows you to filter the sites considered when looking for a valid path. The default option makes all sites in the design optional, but you can move sites to the Required or Excluded columns. Sites in the Required column denote that only paths that contain those (and possibly Optional) are listed. Any path that has a site listed in Excluded column will not be listed in the search results. Note that in large networks, thousands of possible paths may exist and may take a long time to search unless you specify sites in the Required or Excluded columns to reduce the search time. The Site Selection window displays the following options when the Show Options checkbox is selected: • Show Excluded sites names on map: This shows the site name in a different form. • Allow automatic Exclude population for Protection path: When selected the Exclude list is populated with the sites used in the primary path (except Source and Destination). • Use last settings: This populates the list based on the last setting.

Packet Connections, Demands, and Links
....................................................................................................................................................................................................................................
Packet Connections, Demands, and Links Overview
This section is not applicable to GMPLS-enabled networks. Packet Connections
Packet connections are the physical client connections between packet switching OTs and equipment outside the 1830 network. A packet connection establishes a virtual port that is mapped to a muxponder physical port. This allows certain L2 flows to be associated with specific optical endpoints (different routers attached to different client ports on a muxponder, or different router ports associated with different muxponder client ports). The EPT allows you to configure packet connections at each site. A packet demand terminates on a packet connection. Packet connections are defined at a site and do not need any prerequisite equipment or provisioning at the site. Packet connections are bidirectional. Packet connections are only designed and supported on the client ports of the PSS-32/PSS-16/PSS-4 11STGE12, 11DPE12 and 11DPE12E. The 11STGE12 only supports the Fullrate mode, while the 11DPE12/11DPE12E and PSS-4 support the QinQ, Fullrate, and Subrate modes. Note: For the Fullrate mode, up to one packet demand can be associated with the packet connection. For the Subrate mode, 1 to 10 packet demands (reserved bandwidth destined to another site or sites in the network) can be associated with the packet connection, depending on the bandwidth assigned to each packet demand. For QinQ mode, each “line port” packet connection can have 1 to 100 packet demands.The number supported depends of the committed information rate (CIR), or bandwidth assigned to each packet demand. The EPT checks that the total committed bandwidth into any packet connection port does not exceed the port bandwidth, and verifies that the aggregate some of packet flows does not exceed the trail/service bandwidth. The EPT restricts the total number of flows to the provisioning system limits. In an incomplete design, the packet connection is not yet assigned to a specific OT. The Packet connection's OT is assigned a node, OT, shelf, slot, and port after running the design. Packet Demands
Packet demands support transport and grooming of Layer 2 Ethernet flows multiplexed onto a 10G channel. A packet demand runs over a set of trails/services (see Figure 7-24, “Packet Demand Illustration” (p. 7-40)).

Figure 7-24 Packet Demand Illustration
Packet demands allocate a committed bandwidth between packet connection ports. The packet flows use the underlying trails/services and connect the individual packet ports (see Figure 7-25, “Diagram of Packet Flows and Connection Ports” (p. 7-40)). Multiple packet demands can use the same packet connection. Figure 7-25 Diagram of Packet Flows and Connection Ports
Packet Links
The EPT supports the automatic and manual configuration of trails or services provisioned as packet links. Trails with packet OTs automatically become packet links and support packet demands. Trails and services provisioned as packet links carry the packet traffic between packet switching OTs. A packet demand between two packet connections is supported without the packet link having been created, in this case, one or more packet links will automatically be created when the design is run. Packet links are displayed in the Trails Information Tab, Services Information Tab, Trails Report, Trail Routing Report, Services Report, Links Information Tab, and Link Report (see Chapter 11, “Reports”). The EPT supports OT-to-OT connections for packet demands. This link type is currently supported between two 11DPE12 OTs on the PSS-4, and PSS-32 shelves only.

Design Options Overview
The EPT supports incremental design in projects, a feature that allows the user to freeze a completed design and then add new components to the design without changing the frozen part of the design. Sites, segments, connections, trails and services may all be added to a frozen design without modifying any part of the frozen design. The design must be in the Complete Valid state to initiate a new design increment. Design States
The status of a design element is defined as one of the following states: •
•
Not Designed: The network has never been processed by the EPT, has been returned to the Not Designed state by having all of the design results removed, or no links, trails or services exist in the network. For existing trails/services: route them, then run the network as a new design to it to become “Complete.” Incomplete: The following will cause the design to become incomplete: – – – – – – – –
•
One or more trails, services, WDM links, or Packet Demands are “Not Designed” “Equip unused segments with DWDM Links” is selected in Network Parameters, but any segment does not have a link on it. One or more Trail is “Routed, Incomplete” There is a PTPIO card entered via the GUI at a site which has not been connected to any Optical Line at that site. There is a PTPIO card entered via the GUI which has not been manually connected (via the GUI) to any PTPCTL or 11DPE12A card. There is a PTPCTL card entered via the GUI which has not been manually connected (via the GUI) to any PTPIO. If the network is in GMPLS mode: if one or more WDM demands, or WDM links is Complete, Unverified. If the state of the Network is one of “Complete, valid”, “Complete, Invalid”, or “Complete, Unverified”, and subsequently: If deleted a SRG in the failure scope, changed a SRG in the failure scope, or changed the failure scope for the network.
Complete, Unverified: All links, trails and services are complete, but not all have been validated. A demand is complete if it has been routed. A link is complete if the link has been routed, spans created, all OAs selected, all DCMs selected, and all link parameters specified.

Running a Design Overview
After creating the needed sites, segments, and traffic demands, trails and services, the design analysis engine can be run to determine if the design is valid, and if so, to specify the NE equipage needed to satisfy the network design criteria. Before running a design, you must specify each site as either OADM, ILA, DGE, or Glass Through (see Figure 5-11, “Site Details Window” (p. 5-50)). Manual Configuration of Design Elements
Using the Run Design feature is the recommended procedure for configuring DWDM networks. Even if manual editing is required, having the EPT define the NE, nodes, and links is faster than manually configuring these elements from the GUI. The scenarios where a network cannot be completely designed using the Run Design feature are: •
• •
Hybrid Networks consisting of multiple NE types. Use the Run Design feature for the 1830 PSS NEs. Auto-design of PSS-4 is supported only when Cost Optimized is selected in the OA Selection Algorithm field on the Network Parameters window. 88 channel systems using even channels on a portion of the network Split Shelf NEs (separating east/west fiber interfaces onto different shelves)
Design elements automatically designed by the EPT are shown as Auto in the respective Information Tab such as (NE, Node, and Link). If you manually create or edit any of these elements, the state changes to Manual. Further iterations of using Run Design have no effect on elements in the manual state. To reestablish automatic re-configuration of elements in the manual state, delete these elements by selecting them in the Information Tab, or by selecting Action > Remove Whole Design. Note: The EPT may override some manual configurations when running the design. For example, when nodes/settings are not supported in previous configurations, or to choose default configuration settings as a more cost-effective option. Simulation Time
Running a large design may take over one hour to complete. By limiting the amplifier choices on the Amplifier Auto Placement tab of the Network Parameters window, design time may be reduced since the EPT would process fewer amplifier permutations. For iterative designs (to clear errors or add additional traffic to a complete design), using the Verify Design feature “Verifying a Network Design” (p. 8-10) results in faster simulations. The Verify Design feature will not alter NE hardware, but it may result in power setting changes for elements in the Auto state.

GMPLS Design Considerations
In GMPLS designs when nominal routes are deleted, you must run the design to ensure that all associated restoration regens are removed before the design file is saved. Procedure ...................................................................................................................................................................................................
1
To run the design, click Run Design on the toolbar. Result: The Run Design Options window is displayed (see Figure 8-1, “Run Design
Options Window” (p. 8-5)). You can choose whether to retain all network design elements, remove only the EPT-design elements, or remove EPT- and user-design elements. Figure 8-1 Run Design Options Window
Do not remove any designed elements (also referred to as Run Design option 1)
allows elements that have been slotted to stay where they have been placed, and speeds processing when using the PLDM optimizers. The other options, Remove all auto-designed elements (also referred to as Run Design option 2) and Remove all user-designed and auto-designed elements (also referred to as Run Design option 3), do not remove deployed projects or objects. Segments, demands, trails, services, packet connections and OT-to-OT links that are not in the Current or Deployed Project are treated as if they do not exist. Deployed objects will not be changed by any of the design options. ...................................................................................................................................................................................................

Verifying a Network Design
....................................................................................................................................................................................................................................
Verifying a Network Design Overview
The Network Verification feature allows you to modify attributes (such as fiber characteristics), verify if the changes are valid, and decide whether to accept the changes (if valid) or revert back to the original values. If a network was designed using preliminary or estimated fiber characteristics, you can test whether the design is still valid when actual fiber characterization data is available. You can also test how much margin a design has by changing fiber characteristics and verifying that the design is still valid. For example the user can increment the loss margin and test whether the design is still valid. Note: Starting from EPT Release 8.1, Design Verification (using the Verify Design or Run Design buttons) no longer changes the OSC SFP types. This also applies when opening a Complete and Valid design configured in earlier releases, and then opening it in EPT Release 8.1. If you encounter an error, see “Demand and Design Errors” (p. 14-9). Procedure
Note: You cannot perform this procedure if the network design is in the Not Designed or Incomplete state. ...................................................................................................................................................................................................

Running an Incremental Design
....................................................................................................................................................................................................................................
Running an Incremental Design Overview
The EPT supports incremental, phased design and/or concurrent design of a network divided into several Projects (in GMPLS designs, Future projects are not supported). This feature: •
•
Allows you to freeze a completed, deployed design and then add new components to the design without changing the deployed portion of the design. Sites, segments, connections, trails, services and demands may all be added to a frozen design without modifying any part of the frozen design. The Project must be in the “Complete, Valid” state to be moved to the status to Deployed. Allows a design to be divided into projects. Some projects may be deployed, some in active rework or design, and some may be marked as Future and set aside (or are be worked on by other engineers and not of immediate concern).
Working with Projects in Incremental Design
EPT supports subdividing the network into “Projects.” Projects consist of the segments, trails, services and demands design elements, and may be in one of three Status values: • •
Future Current
•
Deployed
All other network design elements have derived status from the status of segments, trails, services and demands. For example, a link is considered deployed if all the segments it traverses on are deployed. The behavior of the project types is as follows: •
Projects with status set to Future—Elements contained in a project with status set to Future are ignored by EPT for network design. The Run Design and Verify Design functions have no effect on Future design elements. The power, gain, and other values for these elements is unchanged during a Run Design operation. If the Project is provisioned for Retain Routing set to no, trails and services are unrouted when moved to a Project with this status, so they do not take away channel bandwidth from the Current project. If the Project is provisioned for Retain Routing set to yes, trails and services retain their routes when moved to a Project with this status, then trails and services in the Current project will not be able to use the channel bandwidth that these trails and services retain.

Running an Incremental Design
....................................................................................................................................................................................................................................
The cards contained in the future Project(s) are treated as real for some aspects of the design, the shelf slots they occupy cannot be used by cards designed in the Current project, the shelf power they consume is considered when designing power filter sizes during run design, the optical line power on future links is considered when designing the current links, and so on. •
•
Projects with status set to Current—There is only one project with the status set to Current. Elements contained in the Current project are designed and validated. New cards added during Run Design are placed in the Current project. Projects with status set to Deployed—Elements contained in a project with status set to Deployed are resources available for EPT to route additional traffic trails, services, and demands, but are not modified by the Run Design function. The power, gain, and other values for these elements is unchanged during a Run Design operation (see Step 4 for the method to change power and gain on Deployed elements). In addition, elements in the Deployed state may not be modified by manual design procedures. Network Parameters that affect elements in the network (for example, Fiber Margin) may not be modified when there are projects in the Deployed state, as changes to these parameters may invalidate a design or cause changes to the Bill of Materials for these elements which have already been installed or deployed.

Modifying Projects
Table 8-2, “Changing Project States” (p. 8-18) describes restrictions when moving elements from one project status to another. Table 8-2
Changing Project States
Design Object Segment
Status Change
Result
Add to a Future Project
The segment is now a member of this additional project, it retains its membership in any other projects where it is already a member.
Delete from the Current Project
Any current trails and services routed over the segment will be unrouted after confirmation; Current project trails and services cannot be routed over segments in Future projects. If the segment is a member of the Current project only, this action will move the segment to the project named “None” (the segment is never left as a member of no project).
Trails, Services, and Packet Demands
Deployed to Current
The state and route remain unchanged. (If a packet link is moved from a Deployed to a Current project, the packet demand routed over it also moves to the Current project.)
Current to “Future”
The route will be retained only if the project is provisioned for Retain Routing set to yes; otherwise the route will be removed. (If a packet link is moved from the current project to a Future project, the packet demand routed over it will also be unrouted.)

The branches of the tree root are: •
Design History
•
Site - Sites have child nodes in the tree for Network Elements, Nodes, L2 Packs, Glass-Throughs, and Packet Connections. Each child of a site is listed in the tree. A merge will be performed if site names are identical. NEs with common names, and nodes within NEs with common names will be merged. However, all sites, NEs, and nodes that do not have an exact name match in both files will be added to the destination file with no additional merging functions performed on those entities. Segment - The Primary and Secondary files should not have common segments. Segments with the same A-end and Z-end in both designs will be added during the merge as a new segment between those two sites.
•
• •
Trail Project - All project names must be unique, else they must be renamed (see Step 6). Objects in the “Current” project in the Secondary file are merged to the “Current” project in the Primary file. If the name in the Secondary file is unique, then the “Future” project will be merged to the destination file. “Deployed” projects in the Primary file are allowed, but if any project in the Secondary file is “Deployed,” the merge cannot be performed. (All objects in the secondary file are merged to 'current' or 'future' and therefore doesn't interfere with any deployed object in the primary file.)
• •
• •
Span Link - Links are not merged. Instead, links from the secondary file are added as new objects in the destination file. All OA, DCM, PTPIO, LBO, and other entity details in the Link Attributes Selection window are preserved for primary links and secondary links during the merge process. Transparent Link SRG (GMPLS designs only) - All SRG names must be unique, else they must be renamed (see Step 6). Any failure scopes in GMPLS designs are not merged; the failure scopes from the Primary file will be used. Destination's restoration routes, feasibility calculations, and 3R resources are removed during the merge.
•
System - Any defined system that is invalid must be deleted.
•
Network Configuration is a child node that displays a summary in the main panel of the parameter conflicts.

The Primary design is the source of the global Network Parameters. The Secondary design will adopt the global Network Parameters from the first design. If the parameters in the Secondary design preclude merging, an error will be displayed explaining why the merge is not possible. If the parameters in the Secondary design are different than in the first and the merge is possible, a warning will be issued and a difference list presented. You will have then be able to correct the issues as indicated, or abort the merge. Lines: If the number of lines exceeds the limit for a node or an NE, an error will be displayed in the merge UI and the merge will fail. AnyDir Add/Drop blocks cannot be merged; they can only be added to the destination file. When merging lines, the line number for any line cannot be higher that the maximum DWDM lines per node for that site. If so, the lines must be renumbered. The Line Isolation field value should be considered when renumbering lines. ILAs and Glass-through nodes cannot be merged, but they can be added to the destination file if no name conflict exists (to rename duplicate names, see Step 6). Nodes are color-coded depending on their merge status: •
Green: The merge can be completed successfully.
•
Yellow: A problem exists that is preventing the merge from completing. This is usually a naming or shelf numbering conflict. Yellow warnings can be corrected within the Merge window. Red: A conflict exists that prevents the merge from completing, and cannot be fixed within the Merge window. Grey: This node could not be merged because the parent node failed to merge. It is incomplete.
• •
EPT Merge Main Message Panel
The main panel of the Merge window (on the right) displays details on the selected object in the tree, including a successful merge, or warnings. If the object cannot be merged, details of why the merge failed are listed. Naming Conventions
Except for common sites, NEs and nodes, all names must be unique. If a naming conflict is preventing the merge from completing, you can rename an object (see Step 6). Before you begin
The files to be merged must be created using the same build number as the installation of EPT. If not, you must open and save the older file to update the build number for that design before you can proceed. And in general, all sets of parameters of the NE will be required to match to move to Shelf and Shelf Set merging phase.

1830 PSS Commissioning Support in the EPT Overview
This section describes how to use the EPT design with the Portable Provisioning Tool (PPT) (described in this chapter) to provision each 1830 PSS NE in the network according to the EPT design. The EPT supports generation of Commissioning Files (one file per commissioning system) which are used to provision the following to the 1830 NEs: • • • • • • • •
Network Element type, System Identifier, shelf types, node types (ROADM, TOADM, DWDM FOADM, CWDM FOADM), shelf numbers, and so on All card types, slot locations, SFP, XFP, CFP pluggable types/location All topological connections between card ports Amplifier target power, nominal gain, power and gain ranges, tilt, ripple, and other parameters used by the transmission software on the NE Network Topology; that is, the NE to NE fiber links and orientation with respect to each other Port to Port and fiber span loss information Optical Channel Power Offsets Feasibility information for the network GMPLS software for decisions regarding restoration path routing (in GMPLS designs only)
System Commissioning Files created by the EPT are used as inputs to the PPT, which converts the file contents to commands sent to each NE in the system. (See also “Commissioning Alternatives” (p. 9-10), for commissioning without the PPT.) For information on how to use the commissioning files created with the EPT to provision/commission an 1830 network, refer to the Nokia 1830 PSS Portable Planning Tool (PPT) User Guide.

Commissioning Systems for Commissioning File Creation
Divide the EPT network into a set of commissioning systems. Each system is a subset of Links that comprise a linear or ring topology path extending along the THRU path (also known as express) of each node: •
A mesh topology must always be divided into linear or ring systems for commissioning and maintenance.
•
The THRU path uses the jumper between two CWR/WR THRU ports to get through the node. This is also sometimes referred to as the express path. On FOADMs this is the jumper between SFD EXP ports or ITLB E or O ports through the node. For a valid system, a node cannot exist in the linear path or ring more than once (except to close the ring). The EPT will produce separate commissioning files for each of the systems that comprise the network.
• •
The EPT will confirm that the selected system is valid. EPT commissioning files are used by the PPT tool to commission and power balance each system individually. See also the Nokia 1830 PSS Portable Planning Tool (PPT) User Guide. Full Commissioning Systems
To use Full Commissioning Systems, the system must contain the linear or ring path extending on the THRU path through each node until it connects to a node degree without a THRU path, or a one degree node or circle back on itself in a ring. In a system that has no rings, if you follow the THRU paths through every node, and the THRU path traverses one node several times, you must use Partial System Commissioning. Partial System Commissioning
Note: Partial System Commissioning should be avoided when possible, as it requires additional manual procedures to perform NE power commissioning. When using the Partial System Commissioning feature, you can specify a set of links to create a commissioning file, and the set can end in the middle of an NE's THRU path. When selecting links for a commissioning file, the two cards can reside in different commissioning files if the cards form a THRU path in an NE. Partial System Commissioning may be used to commission an incremental component of an existing network. ...................................................................................................................................................................................................

Some networks have no valid Full Systems, for example a “figure eight” network. Use Partial Commissioning for such networks. Each Config D’ (ROADM/TOADM with two NEs) and Config D” (ROADM and TOADM with one NE) AnyDirection Add/Drop Block that consists of an AnyDirection Add/Drop line on a ROADM, and a AnyDirection Add/Drop Line on a TOADM and a DWDM link in between, must be in a system alone without any other links. When provisioning/commissioning a network, the network provisioning must match the provisioning in the EPT, or the PPT provisioning may not work. After provisioning and/or commissioning of a system using the PPT, any change made to the provisioning of the system must be reflected back in the EPT design and new system commissioning file(s) generated before running the PPT again. (For example, changing an OT line port ITU channel in the NE.) You cannot create a commissioning file unless the design state of your network is “Complete, Valid” (see “Design Options” (p. 8-2)). You should save the design before creating a commissioning file. You should enter the EPT System Identifier (SID) for the NEs that are used in the system (see Table 5-10, “Network Element Parameters” (p. 5-92)).

Commissioning Alternatives
Alternative methods for network commissioning that do not use the PPT include the following: 1. The 1830 WebUI supports import of an EPT-created Commissioning File, which it uses to pre-populate commissioning values to the current Power Commissioning screen or GMRE Commissioning windows (only applicable if the EPT design is GMPLS-enabled). Note: The WebUI has three GMRE Commissioning windows. For example, on the WebUI, you can select Administration > Power Commissioning, click on the arrow icon at the top/right of the Power Commissioning window, browse to the EPT Commissioning file on your PC, and the values from the EPT file will be pre-populated into the WebUI screen. (Some of the GMRE Commissioning screens on the WebUI have an explicit Import button instead.) 2. The EPT Power Commissioning and GMPLS Commissioning Reports (see Figure 11-51, “Power Management Report” (p. 11-76) and Figure 11-55, “GMPLS Commissioning Report” (p. 11-79) respectively) can be used to manually view the EPT design values so that it can be manually typed into the 1830 WebUI Power Commissioning screen or GMRE Commissioning windows. Re-Commissioning
Re-commissioning may be applied in the following cases (this is not an exhaustive list): • • •
Change amplifier type (possible new EPT file) Add/remove node in ring/linear chain Fiber segment replacement
•
Change the number of channels (migrate from 44 to 88 channels)
Once the EPT design modifications are made, run the design to bring the design into a Complete, Valid state again. If the network has had trail or service deployments that are not reflected in the current EPT design file, you can use the Upload feature (see “Import Network Data” (p. 12-1)) to check the EPT design against the physical network, and add the additional trails or services from the physical network to the EPT design file. Create the new Commissioning Files. ....................................................................................................................................................................................................................................

GMPLS Concepts in the EPT Overview
The EPT, when set to GMPLS-enabled, is used to design the network to ensure the capacity to support the route restoration required for the specified GMPLS failure scenarios. For more information on GMPLS, and its use in the 1830 network, refer to the Nokia 1830 PSS GMPLS/GMRE Guide. Basic GMPLS concepts supported by EPT are: • • • •
•
•
GMPLS Failure Scope are definable in EPT. For example: all segments, all segments and all sites, or a custom defined set of segments and sites. Shared Risk Group (SRG): A grouping of segments and/or sites that are treated as one, failure risk, when choosing diverse paths and restoration paths. Failure Count: The maximum number of simultaneous failures that need to be protected/restored (accessed from Action > GMPLS Failure Scope. A failure scenario is one or more (up to a maximum of Failure Count) segment and/or sites, from the failure scope, that fail simultaneously. A route can be restored, for a given failure scenario, if it can be rerouted to avoid all failed segments and sites in the failure scenario. You can specify for each trail, whether the route(s) should be restorable. EPT will pick the nominal path for each trail definition, and report on whether this path can be restored in all failure scenarios. Services are not explicitly restorable, but will use restoration routes based on the settings of the trail(s) the services use. EPT will design the equipment so that each trail specified as requiring Restoration can be restored. Equipment such as AnyDirection Add/Drop Blocks, 3R OT regeneration equipment necessary for route restoration paths, and so on will be added to the design.

•
The EPT Commissioning File includes, per OT category, the threshold values for OSNR, PMD, and so on for the GMPLS algorithms to use in feasibility decisions when choosing valid restoration paths at any time.
•
The EPT Commissioning File also includes line feasibility information, per OTS in the network for the GMPLS algorithms to use when choosing valid restoration paths at any time.
Regen Placement Guidelines
The following are guidelines to be used to place regenerators in manual routing for GMPLS designs. OSNR depends on both NLP and PMD, but while the dependency from NLP is of f(NLP), the dependency from PMD is of (PMD^3). This means that OSNR budget can assume very high values if PMD is high. WSS budget is an independent value and increases with the number of traversed nodes dependently from the kind of WSS equipped on each node. When the budget is RED, the route is traversing too many nodes. As a generic rule the order in which to address the physical issues is PMD,NLP,OSNR and WSS count. For example, if in one direction both OSNR and PMD percentages are red and other values are green, then evaluate PMD first. The first site in which a regen can be placed is the last site with PMD lower or equal to 100%. If the OSNR budget is the only red value, the first site in which it is possible to place a regenerator is the last one in which the OSNR is less than 100%. Regenerators must be placed in positions that have a WSS count lower than 100%. So if for example, WSS count and OSNR percentage are red and the other values are green, the first site in which it is possible to place a regenerator is the one in which both the OSNR and WSS budget are lower or equal to 100%. It is possible that the placement of regenerator is not enough to obtain budgets below 100% in both directions. The general guidelines provided in this section must be applied per direction. Restoration Options
For more information on this topic, see the Restoration field description inTable 7-2, “Trail Parameters” (p. 7-6). Restoration = Pre-Calculated: Trails specified with the Restoration field set to Pre-Calculated require that the trail is restorable for all failure scenarios affecting that trail. The Run Design command will fail and an error message is displayed in the Errors section of the Information tab (see “Errors” (p. 6-43)): Demand Demand1 Cannot guarantee restoration for demand with pre-calculated restoration.

....................................................................................................................................................................................................................................
Note: In the 1830 physical network, network resources are reserved for restoration paths in this mode. Restoration = Upon Failure: Trails specified with the Restoration field set to Upon Failure allows a design status to be Complete, Valid even if the trail is not restorable for all failure scenarios. A warning message is displayed in the Errors section of the Information tab (see “Errors” (p. 6-43)) : RWA Warning--Network restoration optimization warning. Refer to Design Status Details.

GMPLS Network Evolution
Support of network evolution – only Current and Deployed projects are supported in GMPLS designs (not Future). Projects allow incremental or phased design and growth of an installed network’s design. Highlights: • •
Restoration routing is project-less (it is always calculated on whole design) Restoration regenerators can be deleted –
•
Only restoration regenerators in the current project can be removed if not used in a nominal path – Deleting deployed regenerators is not allowed Restoration regenerators can be un-deployed – All restoration regenerators can be removed from a deployed project. They are automatically placed back in the current project. – Nominal regenerators can be removed only by removing trail (or its routing)

Greenfield: •

Nominal regenerators are placed by EPT GMPLS Engine as part of the automatic routing of a trail as well as by manual routing, restoration regenerators are created by a dedicated panel on a given NE. Restoration regenerators can be created automatically by EPT GMPLS Engine, in addition to creation by the panel. User-defined regenerators are reused by EPT GMPLS Engine as much as possible on both nominal and/or restoration routes Only restoration regenerators can be manually removed from the design
Brownfield: Run design options 1 and 2 preserve regenerators placed by user and try to reuse deployed regenerators. Option 3 will remove user-defined regenerators if not deployed or used. EPT GMPLS Engine can use a user-defined restoration 3R that is optically compatible with a trail, even if the 3R is not the pack that EPT GMPLS Engine would place by default.

GMPLS Configuration Overview
Using GMPLS in a network design adds additional protection options on the trails and services created in the network (see Figure 7-3, “Create Trail Window (Clustering Enabled)” (p. 7-6)). Configuring a network for GMPLS consists of several steps: • • • • • • •
enabling GMPLS on a network design (see “Enable the Network for GMPLS” (p. 10-5)) creating (can also view and edit) GMPLS shared risk groups (SRGs) (see “Create SRGs” (p. 10-6) and “View and Modify SRGs” (p. 10-7)) creating GMPLS failure scopes (see “Create Failure Scope” (p. 10-7)) performing GMPLS restoration and path verification (see “Restoration Routes” (p. 10-10)) creating 1621SLE links (optional) auditing of GMPLS (see “GMPLS Auditing” (p. 10-13)) setting up commissioning of GMPLS routes (see “1830 PSS Commissioning Support in the EPT” (p. 9-1)) Note: GMPLS designs do not support alien demands (trails or services that interface to the 1830 PSS network through an MVAC, MVAC8B or SVAC), nor trails or services using certain OTs such as 43STX4, 43SCUP-compatible (or older compatible) demands. Note: In GMPLS designs, to avoid regenerator auto-placement on DGE sites, DGE sites must have the Allow Local Add/Drop on ROADMS disabled (deselected) on the Site Details Automatic Design Definition window (see Table 5-7, “Site Details Window (Automatic Design Definition Tab)” (p. 5-55)). Note: Certain OT-to-OT compatibility rules are stricter for GMPLS-enabled designs.
Enable the Network for GMPLS
You must begin by creating a new network design (see “View or Edit Network Parameters (Network Parameters and Defaults)” (p. 5-2)). ...................................................................................................................................................................................................

1621SLE Long Spans in GMPLS-Enabled Networks
Beginning with R5.1.0, 1621SLE links are supported in GMPLS-enabled network designs. In GMPLS-enabled networks, design of the nominal and restoration paths is supported automatically. However, for a nominal route to traverse the 1621SLE Link, the trail must be manually routed; they will not by default autonomously route across this link due. During “Run Design,” restoration paths will be autonomously designed as needed for all failure scenarios and so on defined across the 1621SLE Link or otherwise as required. All nominal and restoration paths in the GMPLS-enabled EPT design will have regenerators on either end of the 1621SLE link. The 130SNX10 OT supports regeneration onto a 1621SLE link. The following procedure is a high-level flow of steps for using the EPT with GMPLS-enabled and a 1621SLE span: ...................................................................................................................................................................................................
1
Create the design as described in “1621SLE Long Spans ” (p. 13-13). From the Create/Edit DWDM Link window, specify how many channels to be turned up over the 1621SLE link. ...................................................................................................................................................................................................
2
Create a trail and manually route it across the 1621SLE link. Result: This action provides the nominal route. If you want EPT to find the route
automatically, you may skip this step, but note that EPT will not choose a nominal path across the 1621SLE link by default. ...................................................................................................................................................................................................
3
Click Run Design and select the option “Do not remove any designed elements.” Result: EPT computes the OT types and wavelengths of 3R resources required to
restore traffic for all specified failure scenarios, including on either end of this 1621SLE link, and routes remaining trails. ...................................................................................................................................................................................................
4
Using the 1621SLE SNDP tool, design the number and OT type of the wavelengths across the 1621SLE, and the specific wavelengths per the 1621 loading plan. (More wavelengths than needed can be designed in 1621SLE SNDP tool.) ...................................................................................................................................................................................................
5
Edit the EPT design using the wavelengths picked by SNDP for each type: • •
To edit a nominal trail, right-click on the trail or service and select Editing Nominal Channel(s) on 1621SLE. To edit a 3R resource wavelength, right-click on the 1621SLE link and select Edit Restoration Channel on 1621SLE.

GMPLS Auditing Purpose
EPT allows you to create and manage Audit Scenarios in GMPLS designs. EPT uses GMRE Path Computation (GPC) to perform a GMPLS audit, which consist of the following audit scenarios: •
Trust Workflow: GMPLS audit mode is used to run restoration analysis without changing the Baseline EPT GMPLS Design (BEGD) to assess if the restoration plan determined by EPT/RWA is confirmed by GPC.
•
Robustness Workflow: GMPLS audit mode is used to run restoration analysis after some changes to the BEGD to assess if the restoration plan determined by EPT/RWA is robust to changes in the planning assumptions.
Before you begin
Before you can perform a GMPLS audit, you must run a GMPLS-enabled network design that results in a Complete, Valid or Complete, Invalid state. Running a GMPLS Audit ...................................................................................................................................................................................................

GMPLS Design Conversion Overview
GMPLS Design Conversion is a feature that allows you to change a network design upgrade from non-GMRE to GMRE and downgrade from GMRE to non-GMRE. The EPT will check that configurations are valid before doing the conversion. GMPLS Design Conversion Impact on Default Profiles
When a network design is converted to or from GMPLS characteristics, the default profiles (see Figure 2-15, “Design Options Window” (p. 2-24)) are impacted as follows: This Default Profile...
Changes to or From
Core HiPerf

Core HiPerf CDC-F
Core HiPerf CDC-F GMPLS
Metro HiPerf iROADM
Metro HiPerf iROADM GMPLS
Note: Core HiPerf C-F cannot be converted to GMPLS. Prerequisites When Upgrading From non-GMPLS to GMPLS
This upgrade is only allowed on Complete, Valid designs. Several elements are not supported in GMPLS designs. Before you initiate a design conversion from non-GMPLS to GMPLS, be sure that none of the following conditions are present in your network design. Otherwise, you will not be able to convert the design. •
• • •
The following OTs: – All OTs under 10G, including 4DPA2, 4DPA4, 4QPA8, 1DPP24M – 112SDX11, 43STX4, MVAC, MVAC8B, SFD40/SFD40B and SVACs User-defined aliens Fixed frequency line pluggables OT-OT trail connections Note: EPT supports OT-OT trail connections and OT-OT link connections. OT-OT trail connections are used in client line ring applications and are supported by GMPLS designs, OT-OT link connnections are used for packet demands and are not supported.
• •
Packet demands TOADM and DFOADMs except one degree DFOADM nodes are allowed at either end of a 1621SLE link; the DFOADM must be in the same NE as the ROADM
....................................................................................................................................................................................................................................

GMPLS Design Conversion
....................................................................................................................................................................................................................................
Even if GMPLS does not support a multi-hop 1621SLE link, since EPT allows designing multi-hop 1621SLE links, it is acceptable to allow the conversion of a one degree DFOADM node that has degree 1 and is connected to 1621SLE link even if there is no ROADM in the same site. • • • •
CWR8 and CWR8-88 CWDM and SCHAN network configurations DWDM 100 GHz links (Only DWDM-50GHz, DWDM-FLEX, and 1621SLE-50GHz link types are allowed in GMPLS-enabled networks.) Asymmetric fiber types on each side of glassthrus
• • •
DSF and LS fiber types Future projects ENSCP, OPS Dual Interface, and OMSP protection
• •
WT Keying disabled Dispersion Compensation set to Manual (Verify Externally)
• • •
Client/line rings have restrictions on trails used to create rings Protected cascaded configurations Symmetrical Add/Drop configuration on A-end and Z-end This applies only when OPS Single Interface protection is enabled and if there's a asymmetrical A/D configuration on A-end and Z-end.
•
Amplified OT usage in Network Parameters set to Prohibit Standard ASE OTs or Prohibit Low and Standard ASE OTs
• •
• • • •
•
OT modes not supported in GMPLS A site containing an IROADM node with at least one line supporting PSC1-6, or if the site is configured in such a way to force automatic PSC creation as consequence of automatic design. Network Parameters default setting for Segment Capacity is not DWDM50GHz or DWDM-FLEX. Trails with 12P120 on A-End and/or Z-end and FEC is S-EFEC, or if the default OT is a 12P120 with S-EFEC. A non-GMPLS design using FLEX links should be converted to a GMPLS design with FLEX links. NOFEC is not supported on the OT line side in GMPLS. This applies for the tunable XFP and tunable zero chirp. Note that OPS Single Interface protection uses cascaded trails over an OPSA-NOFEC. Designs using the following differential phase encoding OTs cause the conversion to fail: – D5X500-QPSK-nodcm-diff-SDFEC-G2 – 2UC400-compatible-QPSK-diff-nodcm-SDFEC-G2

GMPLS Design Conversion
....................................................................................................................................................................................................................................
Only absolute phase encoding for the D5X500 QPSK and 2UC400-compatible QPSK modes is supported in GMPLS. •
Design conversion from non-GMPLS to GMPLS is denied if there is a cluster site
Prerequisites When Downgrading From GMPLS to non-GMPLS
This downgrade is only allowed on Complete, Valid designs. Before you initiate a design conversion from GMPLS to non-GMPLS, be sure that none of the following conditions are present in your network design. Otherwise, you will not be able to convert the design. •
Deployed/user restoration regens
•
Trails with an automatic nominal regen. Non-GMPLS designs do not support automatic placement of regens, so after downgrade the design will be invalid because the trail will be non-feasible. You must manually route the trail with a user-created nominal regen.
Post-Conversion Actions
After converting from a GMPLS network design to non-GMPLS, EPT will perform the following actions: • • • •
Remove restoration routes Set Restoration to None for all Trails Set Route Disjointness to None for all Trails Set Failure Scope to default (allSegments + failureCount=1)
•
Design turns to Incomplete state, Run Design option 2 is required (see Step 1).
Restoration Routes in GMPLS designs will be deleted when converted to a non-GMPLS design. They will not be restored if the user converts back to a GMPLS design. SRGs in GMPLS designs will be deleted when converted to a non-GMPLS design. They will not be restored if the user converts back to a GMPLS design.

EPT Reports Overview
Reports are available to display network information in a clear and readable format. These reports are generated as HTML pages or Microsoft Excel spreadsheets that can be viewed, saved, and printed. Several other reports combine related information from different areas to present a unified view of the network. Reports are launched from the Reports menu. An Equipment View report is provided which shows graphics of the shelves populated with their circuit packs as designed by the tool. The entire network equipage can be viewed and you can also view individual sites and NEs. Zoom options are provided to control the display for optimal viewing. There is also a report of the details of the design status which is intended to help debug why a design analysis may have failed or not been able to be completed. Important! Most of the reports will not contain meaningful data until after you run the design. Note: When opening a GMPLS design that was created in EPT R3.6.50, R5.n. R6.n or R7.n, with an EPT R8.0 or later release, it is recommended before generating any report, to run the design. Be sure to select the Remove all auto-designed elements option (see Figure 8-1, “Run Design Options Window” (p. 8-5)). The available reports are described in the following sections.

The Current (Incremental Difference over Deployed) options contains all of the Installation Report connection types: •
•
Jumpers/cables for each connection listed in the corresponding BOM (note that in the BOM if a connection between two cards has an attenuator in an attenuator drawer, the jumper count may be more than the Installation Report’s connection rows) SFP/XFP/CFP is listed in the corresponding BOM

N D O F S T E P S
Additional Considerations Connection Type
The Connection Type column lists the name of the electrical cable or optical jumper required; XFP or SFP if the row represents which type of pluggable to plug into the port of an OT card; or FOADMINV if the row represents a cable connection to the FOADMINV part. The table provides the information about the A-end and B-end of a "connection", providing the type of card or part, the line, shelf, slot, and port that the cable or part plugs into on both the A and B ends. For the case of XFP/SFPs plugging into an OT, the line, shelf, slot and port are the same on the A and B ends, the A-end will list the OT type and the B-end will list the XFP/SFP type. Attenuators
The Attenuator column (see Figure 11-5, “Installation Report” (p. 11-10)) lists any attenuator information needed in between the A-end and B-end, including the location of the attenuator. If the attenuator value is displayed as “2 TBD”, the attenuator values are to be determined (TBD) at installation time and two attenuators are needed--one in each direction. Note: Attenuators that are NOT on the faceplate of either the A or B end card will require two fibers, one to the attenuator and one from the attenuator. The attenuator location in this case will be listed as the attenuator drawer. Note: The Installation Report does not list the two jumpers needed on either side of the attenuators on separate rows; it is listed on one row with the attenuator note in that column. The Bill of Materials Report lists a count. So the count in the BOM may be different that the number of rows in the Installation Report. The column in the Installation Report is not the jumper count, it is the connection type. Smart SFPs
Each Smart SFP will have a corresponding regular SFP for the 11QPE24 client port. Only the SFP connection between the 11QPE24 client port and the corresponding regular SFP is displayed in the Installation Report.

EPT Representation in the Installation Report
The current EPT convention for handling the cabling of unidirectional amplifiers in ILA is always to associate to the amplifier the number of the line from which it receives the signal. Considering this example, for the amplifier in slot 3, the line number 1 is reported and for the amplifier in slot 4 the line number 2 is provided instead this for both and the OSC (see Table 11-1, “OSP Fiber Connections (A-End Only)” (p. 11-14)).

The line number connected to the LINE-IN of the AM2125B in slot 3 is 1. The line number connected to the LINE_OUT of the AM2125B in slot 4 is 1 (but it receives the signal from line 2). The line number connected to the LINE_IN of the AM2125B in slot 4 is 2. The line number connected to the LINE_OUT of the AM2125B in slot 3 is 2 (but it receives the signal from line 1).
In EPT, diversely from other jumpers (which foresee both A-END and Z-End), for an OSP fiber connection, the A-End information is compiled (providing the information of the pack connected to the fiber itself). That is, the line number is the one to which the pack belongs. In the specific case of ILAs with unidirectional amplifiers, the A-END of the LINE-OUT port, accordingly to this EPT convention, provide the line number which

Physical Layer Report Overview
The Physical Layer Report is an Excel spreadsheet that presents all of the simulation data used to verify a network design, including detailed optical characteristics for each WDM demand. The report lists each demand in both A to B and B to A directions. You can run this report only after running the design. It is not saved, and thus will not be available for a design that was opened and not yet run. Note: The Physical Layer Report is only available for Current and Deployed projects (see “Running an Incremental Design” (p. 8-16)). Procedure ...................................................................................................................................................................................................

Total integrated power for a channel maybe determined using the following fields from the Physical Layer Report: • •
NPS44: non-linear phase shift for 44 channel links NPS88: non-linear phase shift for 88 channel links
To convert the non-linear phase shift to non-linear power threshold: Power = 10*log(qNL) +k k = 16.01 for SSMF k = 15.43 for LEAF k = 14.28 for TrueWave-RS

Custom Physical Layer Report
....................................................................................................................................................................................................................................
Custom Physical Layer Report Overview
This section describes the process of creating, deleting, and editing Custom Physical Layer Report settings, which are available for non-GMPLS designs only. The Custom Physical Layer Report is a comma-separated value file that contains entries for all the demands within the current EPT design file. This report provides information pertaining to the calculation of the performance of the demand as it traverses from its source to its destination followed by the same information for the reverse path. As the EPT has evolved, many additional parameters have been added to this report in keeping with the numerical models that are used to predict the transmission performance of the different OT types. Given the increasing complexity of the report, we now offer a GUI interface that allows you to create custom reports from the EPT. Types of Custom Physical Layer Reports
There are three types of custom physical layer reports (CPLR) currently supported: • •
Comma-separated value (.csv) Excel spreadsheet (.xls)
•
Viewer
Comma-separated Value Format
The comma-separated value CPLR contains an ordered subset of the Physical Layer Report columns. As with the Physical Layer Report, each row is typically associated with an amplifier. The rows specific to a link or direction will be listed in the order of the link path in that direction from the source to the destination. When launched from the Main Menu (Reports > Custom Physical Layer > Create/Manage), a single CSV report will be shown in the default .csv viewer, containing information for each link and direction in the network. When launched from the link or demand tables, only information for the selected links or demands is displayed.

Custom Physical Layer Report
....................................................................................................................................................................................................................................
Excel Format
The Excel spreadsheet CPLR consists of a set of report sheets. Each sheet can be one of the following types: • •
•
Table: A table sheet consists of a subset of CPLR columns for a given link and direction, similar to the CSV report. Chart: A chart sheet consists of an X axis, shown in the A column, which is either cumulative distance or amp identifier, and a subset of CPLR columns for a given link and direction. Diagram: A diagram sheet consists of a drawing of the amplifiers, enclosing nodes, and intermediate spans with additional CPLR column information listed either under the amplifier or under the span, depending on which object the column describes.
When launched from the main menu, one Excel spreadsheet is displayed in the default .xls viewer for each link, direction pair in the network. Note: For a network with many demands, the .xls report will result in the generation of a large number of Excel worksheets. When launched from the link or demand tables, only the link, direction pairs associated with the selected links or demands is displayed. Viewer
The Viewer spreadsheet CPLR consists of a set of one to three report sheets. There is at most one of each type of viewer sheet. Each sheet can be one of the following types: • •
•
Table: A table sheet consists of a subset of CPLR columns for each link and direction, similar to the CSV report, which is displayed in the table area of the viewer. Chart: A chart sheet consists of an X axis, which is currently either cumulative distance or amplifier identifier, and a subset of CPLR columns for each link and direction. In addition, a subset of CPLR columns can be specified to each have an additional associated Y axis. In the case of an additional Y axis, the associated column plot will be scaled to its data values independent of the values of the other plots on the chart. The associated plots are displayed in the chart area of the viewer. Diagram: A diagram sheet consists of a drawing of the amplifiers, enclosing nodes, and intermediate spans with additional CPLR column information listed either under the amplifier or under the span, depending upon which object the column describes. This is displayed in the diagram area of the viewer.
When launched from the main menu, the viewer window will be shown with link drop-down list area populated with all the demands and links of the network. The first link, direction pair of the network will be initially displayed. When launched from the link or demand tables, only the link, direction pairs associated with the selected links or demands will be available in the link drop-down list area.

The chart area (in the middle panel of the window) displays plots of the specified column values for the selected link and direction. The values of numerical column values are displayed as the y values in an x,y coordinate plot. The x axis is either cumulative distance in kilometers or amplifier identifier. The amplifier identifier is a combination of node name, line number, oause (amplifier usage and direction), and oaname (amplifier name). One or more alternate y-axes can be added, each associated with a column. If such a Y axis is added to the chart, the associated column values will be scaled independently and that alternate Y axis will be scaled according to the range of data of the associated column. A given plot can be highlighted, which will cause it to be drawn with thicker lines, by clicking on one of its points or on its legend entry. The table area (in the bottom panel of the window) displays the data of the specified PLR columns in a table. The columns of the table can be re-sized and moved by dragging the column borders and column headers respectively. On the Control panel, selecting the Hide Undisplayed Columns field can be used to hide the PLR column list entries that are not currently displayed in the diagram, chart, or table panels. Deselecting this field causes the PLR column list to display all the PLR columns supported by the shown file (the file selected in the link and direction selection area). When a column is selected in the PLR column list, the PLR column name is displayed below the list next to PLR column, its data type and units are displayed. In addition, if it is currently shown in the diagram, chart, or table, the appropriate associated fields are selected. If the column is displayed in the chart area with its own Y axis, the associated Add New Y Axis field is also selected. You can multi-select items from the PLR column list to apply drawing area display status changes to more than one column simultaneously. However, in this case, the data and viewing information from the set of columns would not necessarily be displayed. ....................................................................................................................................................................................................................................

To specify the information displayed in the panels (link and direction), select the drop-down lists at the top of the window. There are four drop-down lists that determine the link and direction shown: the file drop-down list, the demand drop-down list, the link drop-down list, and the direction chooser. The file drop-down list initially only contains the physical layer report generated when opening the viewer of the current network design. More file options can be added to the file drop-down list by loading another physical layer report. The demand drop-down list lists the demands of the currently selected file. The link drop-down list lists the internal names of the links of the currently selected demand. Finally, the direction drop-down list has two options: AZ and ZA. The Show with field allows the user to select another link and direction to view in the chart and table areas to facilitate side by side comparison. When the Show with field is selected, the drop-down lists to pick the alternate link and direction become enabled. Once an alternate link is selected, the currently shown columns in the chart area will be shown for the alternate link/direction as well as the original link/direction (as specified by the top link selection dropdown lists). In the table area, the currently shown columns will also be shown for the alternate link/direction. Each alternate link/direction column will be next to that of the original link/direction. Note: In comparison mode the diagram will continue to display only the primary link/direction. ...................................................................................................................................................................................................

Importing Network Data 12
Import Network Data Overview
The Import Data Network feature allows you to import network information from the 1830 network using the Network Management System (NMS) and the 1350 OMS to update a previously created EPT design file. Starting from EPT R8.2.2, for GMPLS-based networks, only the Discrepancy Report is supported, without trails, services and Regenerators for restoration purposes. Note: EPT and OMS cannot support the upload of an NE unless the OMS is synchronized with the NE. The Import Network Data Operation is as follows: 1. Start with an existing EPT design (see Notes below). 2. Save a copy of the EPT design in case of error. 3. In the EPT tool, with this existing EPT design file open, select File > Import Design. 4. Compare Import Network Data File and the current EPT Design and report discrepancies if any of the following mismatch: • System Identifier (SID), shelf type, NE type, Optical Node type • • •
Non-trail/service specific card shelf-slot position EC, FAN, power filter APNs (orderable part numbers) WDM link topology
• Non-trail/service specific card-to-port “topological connections” • Segment/Span Loss comparisons 5. For the scope of the import, check that: • •
Values commissioned with ranges are within range (Raman Gain, RX EDFA gain, mid-pack eVOA). Other (non-range) commissioned parameter values from the Import file match the current EPT design values that would be commissioned.

6. Verify that the design is valid, given the values Import Network Data file (for example, Segment Loss, Optical power, EDFA gain, Raman gain, Raman hybrid mid-pack eVOA attenuation). Determine whether the design has used up the Beginning of Life Loss margin, or any of the End of Life loss margin. 7. Discrepancy Reports support conflict resolution between the physical network as determined by the Import Network Data file and the EPT design (see “Viewing the Discrepancy Report” (p. 12-3)). Note: Upload of trail and services is not supported in Release 9.0. Note: After the Import Network Data process is complete, the EPT demands added from the import file are placed into a Deployed Project. Purpose
The Import Network Data feature has the following purposes: •
•
The 1830 PSS NEs are “auto-commissioned” using a Commissioning File created from the 1830 PSS EPT. Any extension of the network or modification may require an up-to-date EPT design with which to make the modifications for the expansion, and can then be used to create new Commissioning File(s). To verify that the network (not traffic matrix) deployed is valid.
Creating the Export File using OMS 1350 for the EPT Import Network Data
To ensure that an upload file works on the EPT design: ...................................................................................................................................................................................................
1
Ensure all NEs are re-synchronized in OMS before generating the upload file. (Re-synchronizing the NE is not service-affecting.) ...................................................................................................................................................................................................
2
Re-synchronizing will resolve all missing APN, pluggable and power values on OT/LD. ...................................................................................................................................................................................................

1588v2 Configuration
....................................................................................................................................................................................................................................
1588v2 Configuration Overview
The EPT supports entry of the basic timing distribution card configuration. Time of day and phase synchronization distribution is supported on the 1830 Network Elements using the IEEE 1588v2 Precision Time Protocol (PTP); frequency synchronization is supported using SYNCE. The PTPIO card places an Ethernet signal onto a 1625nm timing channel to distribute timing over a WDM link. EPT will provide some simple sanity checks of the timing distribution, support the Bill of Materials and Installation Reports for timing distribution cards, port pluggables, and topological connections. EPT does not model external connections such as external timing clock inputs. The 1588v2 configuration has three main components: •
Configuring PTPCTLs/PTPIOs
• •
Configuring 11DPE12As Configuring PTPCTLs/PTPIOs with 11DPE12As
Before you begin, consider the overall 1588v2 synchronization network. Configuring PTPCTLs/PTPIOs
Begin with a network design (any design state is allowed). ...................................................................................................................................................................................................
1
Create PTP cards: right-click and select Create L2-Switch on each site (see Step 1). ...................................................................................................................................................................................................
2
Create PTPIOs and PTPCTLs with their client ports (see Step 2). Note: One PTPIO card includes two independent PTPIO blocks; that is, each PTPIO block has its own client port TPxW. ...................................................................................................................................................................................................
3
In each site, you must associate PTPCTLs/PTPIOs together for building the overall PTP synchronization network. For example, in Site1 (see Figure 13-1, “PTPCTL/PTPIO Blocks in PTP Synchronization Network” (p. 13-4)), you must connect one PTPIO card with two PTPIO blocks connected to the two segments, and one PTPCTL with two client ports.

Configuring 11DPE12As
Begin with a valid network design (with Complete, Valid status), including Packet Link (based on 11DPE12A OTs) and packet demands. ...................................................................................................................................................................................................
1
In each site, you must connect 11DPE12A cards together for building the overall PTP synchronization network. For example, in Site1 (see Figure 13-9, “11DPE12A Blocks in PTP Synchronization Network” (p. 13-8)), you must add one 11DPE12A. Figure 13-9 11DPE12A Blocks in PTP Synchronization Network
You should also: • •
Check that the packet demands transporting the 1588v2 timing are consistently selected according the synchronization network. Manually route 11DPE12A demands carrying 1588 timing
• •
Avoid the usage of 3R when routing the packet links. Avoid restorations of used packet links.

Select the 11DPE12A as root of the synchronization network in the site. You can distinguish the different instances of the 11DPE12A according the WDM demands (packet links) associated to it (the 11DPE12A-Site1-{Demand2, Demand3} card instance is displayed in Figure 13-10, “Edit PTP Synchronization Network Window (11DPE12A Selected)” (p. 13-9)). Figure 13-10 Edit PTP Synchronization Network Window (11DPE12A Selected)
The 11DPE12A cards used for propagating the 1588v2 timing (by data channel) are listed in the L2-Switch section of the Information Bar. The 11DPE12A has 12 available client ports; one client port is used for data transmission. In the Used/Available Client Ports column (as shown in Figure 13-11, “View L2 Switch (11DPE12A Demands)” (p. 13-9)), 0 client ports are currently used (in fact, parameter “Connected”=“NO”), while 11 client ports are potentially available. Figure 13-11 View L2 Switch (11DPE12A Demands)
...................................................................................................................................................................................................

To create the client ports and Jumpers defined in the synchronization network, use the Run Design command (see Figure 8-1, “Run Design Options Window” (p. 8-5)). Note: The Run Design option 1 Do not remove any designed elements is allowed only when 11DPE12A is used as 1588v2 timing. When 11DPE12A is selected in the PTP tree in one (or more sites, the Run Design options 2 and 3 (Remove all auto-designed elementsand Remove all user-designed and auto-designed elements) deletes the routes of packet links and the 11DPE12A packs. A warning is displayed when either of these latter two options are selected (see Figure 13-12, “11DPE12A L2 Pack Removal Warning” (p. 13-10)):

1621SLE Long Spans
....................................................................................................................................................................................................................................
1621SLE Long Spans Overview
EPT network designs allow the inclusion of a span designated using the 1621 Submarine Link Extender (SLE) to extend the reach of that span. The EPT will not design the 1621 SLE equipment; there is a separate tool for 1621 SLE equipment design (SNDP). The 130SNX10 OT supports regeneration onto a 1621SLE link. Procedure
To include a 1621 SLE long span in the EPT network design (with or without GMPLS enabled), perform the steps in the following procedure. ...................................................................................................................................................................................................
1
Create two sites, “Site2” and “Site3,” placed at either end of the submarine link. ...................................................................................................................................................................................................
2
Create a segment between Site2 and Site3, which will be reach-extended with the 1621 SLE. ...................................................................................................................................................................................................
3
Right-click the segment and select Edit Segment. Result: The Segment Details window is displayed (see Figure 5-19, “Segment Details
Window” (p. 5-80)). ...................................................................................................................................................................................................
4
In Segment Details window in the Fiber Properties panel, select 1621SLE in the Type field. In a GMPLS-enabled design, you can enable WTOCM usage if desired. Click OK.

Designing Submarine Links Support of AHPHG, AHPLG, A2325A Amplifiers on WR20-TF ROADMs for Submarine Link Configurations
The subsea TX and RX line loading modules is not modeled in EPT, nor is the submarine system within the span containing amplifiers. • •
Set the WR20-TF ROADM target power transmitting/receiving to/from the Link so that the line loading modules receive the expected power. Span or segment loss is manually adjusted to support validation of the link with these target power values.
Regarding the specified power level ranges: • •
TX Line loading modules support an incoming per channel power (transmitted from the WR20-TF ROADM amplifier) between 0 and -6 dBm. RX Line loading modules examples given from the NE HLR show the outgoing per channel power (received on the WR20-TFM ROADM amplifier) to be: – -15.8 to -21.8 dBm for a link with a maximum of 20 channels (3 dB divergence) – -12.6 to -6.6 dBm for a link with a maximum of 88 channels (3 dB divergence) Note: The EPT DWDM Link and TLINK (Trail) validation results across submarine links are meaningless and can be ignored.
WR20-TFM ROADMs are permitted in networks with the OA selection algorithm set to Cost Optimized/(Growth), but only manual selection of bidirectional amplifiers in the WR20-TF ROADM is supported (on the DWDM Link Details window or the Schematic View window). Auto-design will fail to find amplifiers for the WR20-TF ROADM if the OA selection algorithm is set to Cost Optimized/(Growth). The High Performance OA Selection algorithm will continue not to support OA selection for DWDM link over a “no OSC” segment; it will support the design of OAs on other links in the network even when a segment with “no OSC” exists in the same network. The link over the “no OSC” segment(s) will not be designed. This is needed for mixed networks with a submarine link and other node types that may require OPSYS for unidirectional OA selection. Before you begin
The following procedure is recommended only for two-degree node networks with a link between them.

3
For both sites, go to the Site Details (Automatic Design Definition Tab), select the Equip All non-WR-20-TF 1830 PSS Lines with High Capacity Filters field. ...................................................................................................................................................................................................
4
Create a segment between two sites. ...................................................................................................................................................................................................
5
On the Segment Details window, disable the Optical Supervisory Channel (OSC) supported on this segment when carrying DWDM field. ...................................................................................................................................................................................................
6
In the Length field, enter a short length so the tilt will be ~“flat.” ...................................................................................................................................................................................................
7
Manually add the WR20-TFM ROADM nodes at either end of the segment. Select amplifiers that can meet the target power needs. ...................................................................................................................................................................................................
8
Manually add the DWDM-FLEX or DWDM-50GHz link (you will need a DWDM-FLEX if you plan to route PM-8QAM or SPQPSK signals). Max degree should not be set to 1 because it may grow. ...................................................................................................................................................................................................
9
Manually set the Target power for the two site’s amplifiers to meet the needs of the line loading modules. ...................................................................................................................................................................................................
10
Manually set the loss of the segment so that the Link validates with the target power values. Note: Do not adjust the length, as it will affect tilt. ...................................................................................................................................................................................................
11
Click Verify Design.

Sub-Network Connection Protection 1+1 Protection Configuration
....................................................................................................................................................................................................................................
Sub-Network Connection Protection 1+1 Protection Configuration Overview
The EPT supports Electrical Sub-Network Connection Protection 1+1 (ESNCP 1+1) on the WDM Demand window (using the Source Protection and Destination Protection fields). The following sample configuration involves a WDM demand between A(Site 1) and Z(Site 3); a client signal or ODU on a client port of one OT card at the A-end will be sent on two diverse paths from two of the Line ports on the same OT card. At the Z-end the signal arrives on two of the OT Line ports and one is selected for the Z-end client port. Two OT cards are involved in this configuration--one at the A-end and one at the Z-end. ESNCP Protection by OT Card Type
The following OT Types support the ESNCP 1+1 protection on the Create/Edit Trail window: • •
4DPA4 (FlexMux) 4DPA2
• • • • •

Dual Homed and Diverse Path Protection Configuration
....................................................................................................................................................................................................................................
Dual Homed and Diverse Path Protection Configuration Overview
Dual Homed protection primary and secondary paths, chosen during auto-routing, will be Node Diverse as a preference, but if the network configuration does not support node diversity, the two paths will remain link diverse. The dual homed endpoint must be on two different sites. Diverse Path protection configuration requires the endpoint to be on the same site, two different cards. The EPT permits the source and destination to mix Dual Homed and Diverse Path configurations. An example of Dual Homed protection is shown in Figure 13-21, “Routing Demands with Dual Homed Protection” (p. 13-26). In this configuration, two transponders are at Site 1, one path goes to Site 2 and the other path is diversely routed to Site 4. This protection scheme is often used when the application is protected at the IP layer (using link aggregation groups (LAG) across two different routers). Figure 13-21 Routing Demands with Dual Homed Protection
Dual Homed Protection Configuration
Dual Homed protection is shown in Figure 13-22, “Routing Demands with Dual Homed Protection at the Source and Destination” (p. 13-27). In this configuration, two source transponders are at Site 1 and Site 2, and two destination transponders at Site 3 and Site 4. The desired result is to achieve two bi-directional diversely routed paths between the two sites. To configure dual homed protection at the source and destination, from the Create Trail window and select: •
Dual Homed in the Source Protection field
•
Dual Homed in the Destination Protection field
•

OPS Protection
....................................................................................................................................................................................................................................
OPS Protection Overview
In the EPT, Optical Protection Switch (OPS) protection is supported on TOADM, ROADM, and DFOADM nodes, PSS-32 and PSS-16 Universal Shelves, and 1830 PSS NEs. OPS is the only protection type supported for cascaded trails. Note the following considerations: •
• •
When selecting OPS protection, if the protected trail’s A-end is an OPS protection, the protected trail’s other end must also be set to OPS protection. If the protected trail’s A-end has OPS protection with an alien OT (that is, an OT Type of SVAC, MVAC or MVAC8B), the protected demand’s other end must also be set to OPS protection with an alien OT. The Source or Destination primary and secondary path associated with the OPS ports A and B, must be on the same NE (site), but may be in different nodes within that NE. The trail cannot route toward or over a DWDM link if the network is provisioned with the DWDM Wavelength Tracker Keys field set to Off (unkeyed). (See Table 5-2, “Network Parameters (Auto-Design and Verification Tab)” (p. 5-15).)
OPS Single Interface Protection
This protection type has four components to be provisioned: two Och trails, one trail with OTs, and one service. ...................................................................................................................................................................................................

....................................................................................................................................................................................................................................
Cascading OTs Two-Stage Cascading Options
EPT supports different methods of two-stage cascading for encryption and/or aggregation of lower rate signals into a higher rate line wavelength. The Line signal of OT “A” is connected to one of the client ports of OT “B”: • •
Aggregation of 4DPA4(FlexMux) trails into 11STMM10 or 11DPM12 Cascade of a low speed OT to a high speed OT using one of the supported combinations listed in Table 13-1, “Cascading Configurations” (p. 13-31).
Protected cascaded OT configurations are not supported in GMPLS designs. The following nine OTs are not supported in CDC-F networks in a standalone configuration, but can be used as a cascade with the 130SNX10(LN) as line-facing OTs: The EPT supports the following cascading configurations as shown in Table 13-1, “Cascading Configurations” (p. 13-31). Compatible OTs such as 43SCX4 and 43SCX4E may be placed at opposite ends of the trail. Any configuration with the 11QPEN4 OT can be encrypted. Table 13-1

IROADMF and IROADMV Configuration
....................................................................................................................................................................................................................................
IROADMF and IROADMV Configuration Overview
This section describes configuration scenarios incorporating the IROADMV and IROADMF cards introduced in EPT Release 8.1. These cards will be referred to as IROADMX. The IROADMX cards are supported on the PSS-8, PSS-16, PSS-16II and PSS-32. Supported configurations include: • •
Manual design 50 GHz configuration: IROADMX) +ITLB+SFD44/SFD44B
•
100 GHz configuration: IROADMX) +SFD44/SFD44B
Creating WDM Links with IROADMx ...................................................................................................................................................................................................

On the Network Parameters window (Auto-Design and Verification Tab), in the Preferred ROADM Wavelength Router field, select IROADM and click OK. ...................................................................................................................................................................................................
2
On the Site Parameters Window (Automatic Design Definition Tab), in the Preferred ROADM Wavelength Router field, select IROADM and click OK. When creating a WDM link on an “empty” ROADM node (based on Site that has IROADM as preferred WR card), the EPT will place the default IROADM card, IROADMV. Note: The ROADM is created only if the “empty” ROADM node has a Max Degree field value is less than 5 and the Max AnyDir Add/Drop Blocks value is 0. Otherwise, the EPT will select the appropriate WR card that can be different as it pertains to Site Detail preference. IROADMx cards can be manually created in the Schematic Editor of the Node Details window (see “Creating Nodes with IROADMx” (p. 13-40)).

WR card types option are available after adding WRn on schematic: symbol is enabled or disabled following restriction on the WR card type. For the IROADM case, if Max Degree field greater than 4 and the Max AnyDir Add/Drop Blocks field is greater than 0, WRn is not enabled. All the standard WR cards are available only if OA is added on Line symbol. A node must use and IROADM at each degree/line or no IROADMs at all. If an existing degree in a node is a WR8-88 or WR2-88, you cannot add a new degree with an IROADM. The reverse is also true. Creating IROADMx and Filters (ITLB+SFD or SFD)
IROADM can be configured for support on 100GHz grid (SFD attached to the port) or 50 GHz grid (ITLB+SFD attached on the ADT port). Only one type of filter can be connected to card; at least one ITLB or SFD can be directly attached to the IROADMx. All the other ports can be used to create mesh connection to other IROADM.

4DPA4 Dual Transponder Configuration
In this example (see Figure 13-29, “Example Network Design” (p. 13-50)), create two trails using a single card. Both trails are from Site 1 to Site 2. But the first trail is routed directly from Site 1 to Site 2, and the second trail is routed from Site 3. Figure 13-29 Example Network Design
Procedure ...................................................................................................................................................................................................
1
Create the first trail called OC48(1) using the 4DPA4 (DualTran) pack with the following settings: •
Select Unprotected in the Source Protection field.
•
Enable the Allow Sharing field. Note: GFEC is the only type of FEC available with the 4DPA4 pack.
...................................................................................................................................................................................................
2
On the Primary Destination panel, enter the same configuration values used for the Primary Source panel. ...................................................................................................................................................................................................

Create the second trail called HDSDI using the 4DPA4 pack with the following settings: •
Select Unprotected in the Source Protection field.
•
Enable the Allow Sharing field.
...................................................................................................................................................................................................
4
Because port 1 was chosen for the first trail, choose port 2 in this step; otherwise the EPT will configure the network using two different cards. Note: If the EPT configures two 4DPA4 packs, check that you used different line ports. ...................................................................................................................................................................................................

GMPLS-Enabled Network Upload
....................................................................................................................................................................................................................................
GMPLS-Enabled Network Upload Purpose
Use the following procedure to check that the network commissioned using the EPT-generated Commissioning File matches the EPT design, to confirm that the network was commissioned properly, that physical equipment, power settings, topology, and span losses are close to the design, or to update network equipment or other characteristics in the EPT design file. No upload of the traffic matrix (trails, services and 3Rs for restoration purposes), SRG or GMPLS parameters are supported. Steps ...................................................................................................................................................................................................
1
Design the valid GMPLS-enabled network in EPT. ...................................................................................................................................................................................................
2
All nominal paths in EPT are manually routed in order to retain the route through subsequent design interactions. The Network is installed and commissioned with the EPT Commissioning File, and power balanced. Note: In external media (notebook), the location and type of 3Rs could move in the design file autonomously, but subsequent Commissioning shall not fail if there's a mismatch of equipment. ...................................................................................................................................................................................................
3
Create an upload of the whole network, or a subset of commissioning systems, using CPB/OMS. ...................................................................................................................................................................................................
4
Generate a Discrepancy Report using the upload file and the EPT design. ...................................................................................................................................................................................................
5
Are you using EPT projects? If...
Then...
yes,
proceed to Step 7.
no,

1. Make changes to the design file. 2. Recommission the whole network. Note: If you do not recommission the network using a Commissioning File generated with the new or updated EPT design file, subsequent Upload/Discrepancy Reports may not succeed because EPT will check the previously commissioned and provisioned values. ...................................................................................................................................................................................................
7
1. Ensure the EPT design in the state “Complete, Valid.” 2. Select Action > Deploy. The Current EPT Network Design will be in a Deployed Project(s), which will create an empty new Current Project X and the new Deployed Project Y. 3. Edit the segment that needs to change , so that it becomes a member of the Current Project X. 4. Make the changes to that segment or its line equipment, etc and run design in the Current Project X. (note that some changes will cause a ripple affect and neighboring spans may also need to be pulled into the current project). 5. Create a Commissioning System with the links that have changed. 6. Recommission the network links that have changed. 7. To return all of the items in the deployed Project Y to the Current Project X, you can Delete the Deployed Project Y. 8. To deploy the whole network, deploy Project X now, and a new empty Current Project Z will be created. Note: There must be at least one test channel with optical power, on each span in the export file, in order for the exported power values to be usable in EPT for that span, for Discrepncy checking.

Span or Link Power Errors and Warnings
....................................................................................................................................................................................................................................
Span or Link Power Errors and Warnings Span Loss Error
The Span Loss error occurs when the span loss exceeds the maximum of 32.75 dB required by the OSC channel.
Error Message
Cause
Design Failed. Automatic OA selection algorithm could not find a valid solution
The Run Design or Verify Design button is selected when the design state is Not Designed.
Design Failed. Please contact technical support for further assistance.
The Run Design or Verify Design button is selected when the design state is Not Designed.
Corrective Action
Verify that the worst case span loss is less than 32.75 db, including fiber loss, connector loss, glass-through loss, and fiber margin. Use RAMAN amplification to increase span distances. Minimum Number of Channels Warnings
While the maximum span loss is 32.75 dB due to the OSC, additional transmission loss limitations exist. The minimum power into an amplifier is -32 dBm. If the amplifier power does not meet this requirement, a Loss of Signal (LOS) is declared and the amplifier shuts down due to laser safety issues (IEC 60825). A minimum number of channels may also be required to meet this minimum amplifier input power.

Warning Message
Cause
The following lines require the minimum number of channels given below:
The Run Design or Verify Design button is selected when the design state is Complete, Verified.
LINE: NUMBER OF CHANNELS
Corrective Action
Verify the specified lines have the minimum number of channels. Power Divergence Error
The Power Divergence error occurs when power divergence among incoming channels is too great for OADM. Some channels are amplified more than others during the amplification process, resulting in power divergence. The ALPHG can provide up to 29 dB of gain but divergence can be minimized if the gain is limited to 23 db (known as the “flat-gain region”). In contrast, the AHPHG can provide up to 33 dB of gain and its flat-gain region extends to 26 dB.

....................................................................................................................................................................................................................................
Error Message (1 of 2)
Cause
The design automation ran to completion. However, the resulting design failed verification. See the Design Status Details report for more information.
The Run Design or Verify Design button is selected when the design state is Complete, Invalid.
Note: No error message in EPT R1.0.0. Corrective Action
Examine the Design Status Details report (see “Design Status Details ” (p. 11-75)). Look for the statement: “actual value of power divergence (VALUE) exceeds max allowed value MaxFOADMDeviation (4.00) on SPAN at NODE”. In this case, the power divergence among the incoming channels has exceeded the max value for a FOADM. Add a CWR8 circuit pack at NODE from the line SPAN. Recall the CWR8 circuit pack provides automatic gain equalization. If VALUE is just slightly above the max value of 4.00, it may be possible to replace any ALPHG amplifiers with AHPHG amplifiers but keep the target power at 0.57 dBm. It is recommended to start at last ingress amplifier on the link and work upstream. Although the AHPHG amplifiers may help because they have a larger flat gain region, they introduce more noise and could degrade OSNR performance. Error Message (2 of 2)

Examine the Design Status Details report (see “Design Status Details ” (p. 11-75)). Look for the statement: “actual value of WSSOH (VALUE) exceeds max allowed value OHmax (4.00) on SPAN at NODE”. In this case, the power divergence among the incoming channels has exceeded the max value for a TOADM or ROADM. WSSOH is amount of power that the CWR8 needs to attenuate highest power channel to equalize it with the lowest power channel. The simple solution is to add another CWR8 circuit pack upstream from NODE from the line SPAN. Recall the CWR8 circuit pack provides automatic gain equalization. If VALUE is just slightly above the max value of 4.00, it may be possible to replace any ALPHG amplifiers with AHPHG amplifiers but keep the target power at 0.57 dBm. It is recommended to

(The Design Status Details report displays:The calculated power per channel at the input of the CWR Add Amplifier at NODE-LINE on SPAN X is too low. The calculated value is VALUE. This can be resolved by reconfiguring one of the mesh connected lines by: (A) changing to an AHPHG receive amplifier, (B) reducing the maximum channel count and increasing the target output power, or (C) reducing the power divergence from upstream nodes.) Corrective Action
Follow suggestions A, B, or C listed in the error message. For suggestion A, use a per channel power of 3.57 dB for the AHPHG. Note: The error message does not specify which incoming degree has the low per channel power. In the above example, it could be either Degree 3 or Degree 4. Follow suggestions A, B, or C for one degree at a time and determine if the error message returns and if VALUE has changed.

Special Notices ID_26521: Additional check placed on fiber segments using Raman pre-amplifiers
Starting from Release 5.5, a check was placed on the loss coefficient of fiber segments that utilized Raman pre-amplifiers. The maximum loss coefficient supported in EPT on Raman amplified segments is 0.3dB/km. For releases prior to Release 5.5, designs used loss coefficients larger than 0.3dB/km on Raman amplified segments when loaded into R5.5 and later releases, the EPT will generate errors for segments where the loss coefficient limit is exceeded. To clear these errors while maintaining the existing span loss, it is recommended that the segment loss be set such that loss coefficient is at the maximum allowed (0.3dB/km). The change in segment loss required to accomplish this should then be added to the connector losses. Note: These changes may result in some Trails/Services failing validation. Such instances can be addressed on an individual case basis. ID_14950: APN 1AB375650046 not displayed in the Bill of Materials

A U.S. non-profit privately owned and operated product safety testing and certification organization. Develops standards and test procedures for products, materials, components, assemblies, tools and equipment, chiefly dealing with product safety. UNEQ
Path Unequipped UNI
User-to-Network Interface Unidirectional Path-Switched Ring (UPSR)
A survivable, closed loop transport architecture that protects against cable cuts and node failures by providing duplicate, geographically diverse paths for each service. Adjacent nodes on the ring are interconnected using a single pair of optical fibers. One fiber transports traffic in one direction (for example, clockwise), while the second fiber transports traffic in the opposite direction (for example, counterclockwise). In a UPSR, the source node bridges its outgoing traffic along opposite directions around the ring (on paths provided by SONET synchronous transport channels). In contrast to BLSR, a UPSR: •
is path-specific as opposed to line specific
•
does not allow extra traffic (because traffic is bridged)
•
requires less coordination from source to destination (because the destination network element can make all its decisions without involving the source)
Universal Time Coordinated (UTC)
A time-zone independent indication of an event. The local time can be calculated from the Universal Coordinated Time. UPSR
See “Unidirectional Path-Switched Ring” (p. GL-76) for definition. Upstream
At or towards the source of the considered transmission stream, for example, looking in the opposite direction of transmission. USB
Universal Serial Bus User Datagram Protocol (UDP)
A minimal, datagram-oriented, transport network protocol above the IP network layer that does not guarantee data ordering or delivery. Because it is datagram-oriented, each send operation by the application results in the transmission of a single IP datagram. This contrasts with the Transmission Control Protocol (TCP) which is byte stream oriented and guarantees the delivery and ordering of the bytes sent. Because it is a byte stream oriented, a single send operation may result in a no IP datagrams (buffering), a single IP datagram, or multiple IP datagrams. User Privilege
Permissions a user must perform on the computer system on which the system software runs. ....................................................................................................................................................................................................................................
