The 1350OMS focuses on the Telecommunication Management Network‟s Element Management and Network Management layers. These management layers functions are accomplished by a set of different "applications”. The Element Management Layer (EML) is implemented by the 1350OMS-EML application. The Network Management Layer (NML) is implemented by the 1350OMS-SDH, 1350OMS-PKT, 1350OMS-SONET, and 1350OMS-WDM applications. The applications of the NML provide network functionalities for specific topologies. Each application has it‟s own data and database, with data shared between applications via network interfaces. By means of a unique login, the user is granted the access to the applications according to the security settings. The commands of all the applications are available in the same Graphical User Interface that also provides a unique map. Common functionalities such as alarm and performance correlation capabilities are bundled into components that are shared by the applications. Fault management and Performance Monitoring information is common to all the applications. Every application renders the alarms and the PM results according to the own management, therefore the user can retrieve the data collected for any single application. Craft Terminal is meant for commissioning and for maintenance when the Network Element is not reachable from 1350OMS.


Each application is license controlled and separately purchasable. 1350OMS-EML for the Element Layer functions such as NE creation, SW download, NE data backup/restore. The Network Physical Resource (NPR) module is also part of the 1350OMS-EML application. It manages network construction and inventory on physical resource (i.e. NE, boards, ports). It provides support for manual/automatic physical link creation. 1350OMS-SDH for the SDH technology and for the WDM technology in some equipment, e.g. 1626LM. 1350OMS-PKT for the data technologies, such as Ethernet, T-MPLS, CES (Circuit Emulation Service). 1350OMS-SONET for the SONET technology. 1350OMS-WDM for the WDM technology in some equipment, e.g. 1830PSS. 1350OMS provides users with the ease of accessing and using the eOMS (embedded Optical Management System) to provision the former Lucent legacy network. 1350OMS-eOMS accomplishes both the EML and NML functions. It is integrated with the 1350OMS GUI for single login and common GUI navigation. 

It relies on the Common Fault Management component to display alarms.



It is integrated with EML, SDH, WDM and SONET applications for sub-network management.


The slide depicts a Gigabit Ethernet service across SDH and WDM networks. Ethernet management of 1850TSS requires 1350OMS-PKT. The Ethernet/SDH network is made of 1850TSS equipment. SDH management of 1850TSS requires 1350OMS-SDH. The WDM network is made of 1830PSS equipment. 1830PSS management requires 1350OMS-WDM. While provisioning the Ethernet service, the user selects the end-ports of node A and node F. The Ethernet configurations are executed on node A and node F.

While provisioning the SDH network, the user selects the suitable points of node A and node F. All the SDH nodes between the two points are configured. While provisioning the WDM network, the user selects the end-ports of node C and node D. All the WDM nodes between the two ports are configured.


1350OMS runs on servers with an automatic download of the GUI client from the server to the user‟s P.C. In the server, the usage of the applications is accomplished by the GUI server processes which are driven by the GUI client processes that run on the PC. The PC downloads those processes from the server at the first login and whenever a feature (e.g. open the equipment view) is used for the first time. On this slide, all the applications and processes are installed in one server. The management of the network may require more servers (Master and Presentation) which we will discuss on the next slide.

The 1350 OMS GUI follows a full web-based approach. The user simply needs a standard PC Windows XP configuration with a web-browser, Java Run Time 6, and 2 gigabyte RAM. No manual client software distribution and installation procedure are required.


The type and the number of servers to deploy in the network depend on two concerns: the Network Management System load and the Network Management System constraints. The NMS load can be evaluated taking into account a number of factors; mainly: • the size/configuration of the network, that is the number and type of Network Elements. • the required applications. • the Added-Value components: Open Interfaces, High Availability.

• the number of active users working with the system at the same time.

For NMS constraints, the following rules apply. • The EML application can be split over multiple servers. • Each single NML application can not be distributed over multiple servers. • More applications can co-reside in a single server.


1350OMS-HA is the High Availability application. It requires at least two servers machines. The commitments of High Availability are: • Replication of the Core applications and their relevant data from the Active server to the Standby one. • Monitoring of the health status of the active machine and all its processes. • Triggering the switchover of network supervision from Active to Standby in case the former is unable to

carry out it‟s task. The activation of the Spare NMS in place of the Main one can be done automatically or manually. In principle the protection is provided at the application level: this means that a failure on a single process in any of the Core applications can trigger a selective switch-over involving just the affected application and not all the others. The database of the spare server is populated by the replication mechanisms, but it is kept inactive with respect to the network supervision. According to the customer requirements, High Availability is able to protect single NMS applications, whole sites or partial sites through the following different resilient configurations: •

"1+1”: the Main server is connected with a dedicated communication link to the protecting Spare server, usually located in a geographically remote site when Disaster Recovery Centers are envisaged.

•

"N+1“ [N-plus-1]: multiple servers/applications are protected by only one Spare server that duplicates the application data of all the running applications on the active servers but, upon failure, protects only one application per type.

•

“Mutual Protection”: the Main server is concurrently Active for the first application and Standby for the second one. The other server configuration is dual: the first application is OFF, the second one is ON. This solution aims at providing load balancing in the nominal situation, so better scalability targets. Upon failures the customer could pay some performance degradation while keeping full Network Management capabilities from one host.

This section presents an introduction to the 1350 OMS WDM functionality and its relationship to the Element Management Layer (EML). Futher discussion of the functionality depicted on these slides will be discussed in more detail through out the course.


WDM is a multiplexing technique used to increase the bandwidth of a single mode optical fiber, enabling simultaneous transport of several different signals on one fiber. Each signal is transported into a well-defined wavelength, usually identified as "lambda". 1350OMS WDM supports layers, such as OTS (Optical Transport Section), OMS (Optical Multiplex Section), and OCH (Optical Channel) and presents to the user an end-to-end connection management with these connection rates. 1350 OMS WDM also supports 1350 OMS generic features such as Fault Management and Performance Monitoring. The 1350 OMS WDM application is a Network Management Layer (NML) management system which supports Alcatel-Lucent 1350 OMS WDM Network Elements (NEs) and provides full G.709 model compliance. 1350 OMS WDM Layer Management provides: •

Service creation

•

Network provisioning

•

Network protection management

•

SDH/PKT interworking

•

Optical power commissioning and power balancing

•

Wavelength Tracker capabilities

•

Fault management

•

Performance monitoring


The Web Desktop is the web application which provides a central access point. From this access point, the user is authenticated and from which the user can navigate to the 1350 OMS Web Portal to access 1350 OMS Applications. To start the Web Portal, enter the Web Desktop address in the browser, then enter your login/password in the pop-up window and the Web Portal window is opened.


The Network Topology Map provides a graphical representation of the nodes, physical links between nodes and node and link alarm status. The network map is composed of a left panel which provides a tree of the network and the sub-networks associated with that network. Double clicking on a sub-network from the left panel, causes the map of the subnetwork to display in the Main View panel. The Icons represent the various types of objects represented on the Map.


NEs may be auto discovered or manually created. The slide displays some of the steps associated with the NE creation: WDM NE discovery is performed via the Element Management Layer (EML) Actions menu which opens a Create NE wizard. Using the 1350 OMS EML Creation Wizard, the user can manually create the NE in 1350 OMS. Population of the fields in the Creation Wizard are dependent on the type of NE, the way it is managed and the type of NE interface (TL1+SNMP, CNA, SNMP…etc.). By creating a NE, a Node is created that is used by the NML application, in this case WDM.

Supervising NEs is an essential aspect of the network management. The supervision of an NE consists in establishing a communication that allows the user to perform EML operations such as configuration and alarm management. We will further discuss discovery and NE supervision in a later module.


A physical connection is a connection that uses wires, cables, or optical fibers to connect two physical ports. In the 1350 OMS WDM application, OTS and OS rate connections are physical connections. Physical connections are commonly referred to as topological links (TLs) and are divided into two types: 

Optical Section (OS)



Optical Transmission Section (OTS) 

Optical Section connections can be either internal (provisioned within the NE) or external (provisioned between two NEs.

OTS/OS Physical connections are provisioned through the GUI and are displayed in the maps where they are animated according to the network alarms. OTS links auto discovery is supported by 1350 OMS.


Logical connections (Trails or Paths) in a DWDM network are connections typically between DWDM NEs, spanning more than one DWDM NE carrying one or more (that is, Mux OTs) client signals converted into a single wavelength (or frequency) or multiple wavelengths, with each one carrying one or more client signals. These logical connections are also referred to as optical logical layers. The rates for trail are OTUk, ODUk and the rates for path are ODUk and DSR. For optical channel provisioning there is a dedicated wizard for channel configuration. The Create Wizard provides a series of panels in order to manage the definition of : 1. Optical channel connection parameters

2. Node and port termination points 3. Routing method (Automatic, Manual, etc.) and constraints (link connection, Lambda, Termination Point/Node) 4. Alarms and Performance Monitoring (PM) settings 5. Transmission parameter settings (client ports configurations etc.) There also additional panels not displayed that also require configuration. These include; Wave Key parameters and Order assignment.


The EPT is used to design the NE configurations and traffic services through the network. The EPT data provides minimum and maximum values for span losses, port-to-port losses between wavelength tracker detect points, and amplifier gains. The EPT must be uploaded to the 1350 OMS EML application before commissioning and power balancing can be performed in the 1350 OMS.


The Commissioning and Power Balancing (CPB) software is packaged with the EML application software and is integrated into the 1350 OMS WDM photonic management capabilities. CPB enables the system to perform the following: 1. Discovers the NEs in the EPT file and gets the parameters (e.g. NE model, NE release, SNMP address, SNMP port etc.) for each NE from the EML database and stores them in the CPB database. 2. Uses the EPT commissioning file to validate the NE HW inventory comparing the planned verses installed cards. It configures the internal fiber connections (topological connections) between the circuit packs and sets target power for all amplifier outputs.

3. Enables the user to set up the target power values on the amplifier cards of TOADM NEs in order to match span losses on OTS provided by EPT. Amplified Spontaneous Emission (ASE) power is used to perform commissioning on rings and on the intermediate NEs in linear chains. 4. Applies the new target power values and power balances the optical domain with the services present. The power balancing can be done using a Plan file from EPT or by selecting a NE in the optical domain. 5. Generates a power loss report based on the current power values against the target power settings for the optical domain. Both Greenfield commissioning and power balancing operations also generate Loss reports.


Wavelength Tracker (WLT) technology is a sophisticated but simple-to-use monitoring function that optimizes OA&M tasks. 1350 OMS includes all the management capabilities to drive and exploit WLT technology  Fault connection detection at fiber/WSS level  On-demand per-channel connection (OTU) optical power levels along the route  On-demand per-span (OTS) optical spectrum  High/low optical level threshold adjustment


The Optical Power Display feature is supported for NEs that are directly managed by 1350 OMS WDM. The Optical Power Display option allows the user to access a OTS Power Display screen that reflects the power levels from either the Ingress or Egress transmission directions of a selected port. The OTS WLT power graph displays power measurements on points along one wavelength. You can “jump” from the OTS Power Display to the OTU WLT power graph by use of a cascade menu. The OTU power graph displays an optical fiber view of all wavelengths on a selected fiber. The slide depicts: 1. Access to the Optical Power Display feature via a cascade menu on the Trails list

2. The “Jump” from the Optical Path (OTS) view to the Optical Fiber (OTU) view via a cascade menu 3. The “Jump” from the OTU Fiber view back to the Optical Path view.


WDM NE alarms are correlated to the affected transport objects (OTS links, OTU/ODU trails, DSR paths etc.). The WDM manager receives alarms in real time from WDM NEs through EML layer propagation. 1350 OMS EML provides real time alarm notification processing. These alarms are called Elementary Alarms (EAs). Elementary alarms reside in a centralized repository common to all managed NEs. The slide displays access to the EML Alarm Surveillance from the EML Network Elements list via the Show NE Alarms option for a specified NE. The Alarm Sublist is a basic working window of the EML Alarm Surveillance application. Using the Alarm Sublist, you can isolate the probable cause for a specific alarm type. On the slide, the probable cause “URU-S” stands for “Underlying Resource Unavailable – Card Failure”. This probable cause code is applicable to optical transponders, amplifiers, filters and other 1830 PSS cards.


The slide displays access to the EML Alarm Surveillance window. WDM alarms can be viewed directly from the EML Alarm Surveillance application.


For additional information on an alarm, the user can right-click on any alarmed connection and access the External Applications  Fault_Localization option and navigate to the WDM Routing Display for the corresponding connection.


In 1350 OMS there is a single PM data repository database at the EML level. The generic common component used to manage PM issues for all components is referred to as Converged Performance Monitoring (CPM). 1350 OMS EML provides the following functionality related to management of performance data collected by each NE:  

Start and Stop PM on a specific TP (Termination Point) through .(User Server Manager) USM. Periodic collection of PM data from each NE.



Forced collection of all PM data of a NE through EML–USM.



Navigation to CPM GUI for display of PM historical data and graphical reports built on top of them.


1350 OMS PM operates at the Network Management Layer in conjunction with EML. The WDM manager uses the PM data retrieved from the EML as it relates to the services under measure and presents this data with graphs and tabular reports. 1350 OMS WDM provides the following functionality related to management of performance data collected by each NE: 

Automatic and manual PM data start and stop



Periodic collection of PM data from each NE



Threshold Crossing Alert profiles



Navigation to CPM (Converged Performance Monitoring) GUI for display of PM historical data and graphical reports built on top of them










To gain full access to the 1350OMS GUIs through the Web Desktop, the PC must be configured so that the 1350OMS‟s server can be reached using the server‟s hostname. If the Domain Name Server (DNS) is configured on the PC, it should be configured so that the server‟s hostname is managed. If such a configuration is not feasible, the “server‟s hostname”  “IP address” association must be manually inserted in the following file: 

C:\WINDOWS\system32\drivers\etc\hosts in case the PC runs the Windows® Operating System



/etc/hosts in case PC runs the PC-Linux Operating System


Java Version 6 is required. The system can be invoked from any web browsers.


On the first log in, the user will be asked to change the password. The user password is subject to the following constraints: 

At least 24 hours should lapse since the last change



The new password should contain at least one digit [0-9]



The new password should contain at least eight characters



The new password should contain at least two special characters



The new password should contain at least one uppercase letter



The new password should not contain the user identifier


The web Portal provides the user with a view of all the 1350OMS‟s applications. The Left Tree Panel is a navigational panel which is organized with a hierarchical tree that lists the 1350OMS‟s applications. The applications are grouped as Operation (Management, Alarm, Network Tools) and Administration (System, Data Management and Security Administration). When a folder is selected from the Left Tree Panel, the subtended applications‟ icons are displayed in the Application List Area. The Application List Area allows to start an application, double click an icon or right click the icon to display a Start button. The Message Area displays application‟s and Web Portal‟s messages. The Status bar displays the last application or Web Portal‟s message.


The user can add or remove preferred applications to the Tool bar by means of “Edit  Customize the toolbar” or double click an application and then “Add to toolbar”. The applications added to the toolbar can be listed by issuing “View  Preferred Application List”.


Common system applications are grouped by their logical function as follows: The applications are grouped as: 

Operation - (Management, Alarm, Network Tools) 

Management - contains the MS-GUI Network Management.



Alarm - provides presentation functions for all managed network Alarms.





Network Tools - provides access by cut-through functionality to the Data Communications Network (DCN ) Tunnels EML.

Administration - (System, Data Management and Security Administration) 

System – provides system (machine)Process Monitoring and Control (PMC) and scheduled execution of jobs based on application.



Data Management – includes Backup and Restore operations and NE SW packages EML.



Security Administration – manages user privileges and provides command log file manipulation.


The Network Management application provides the Multi Service Graphical User Interface (MS-GUI), to create, modify, delete, retrieve and provision the NEs and the SDH, SONET, WDM and PKT network. It provides inventory lists for querying the content of the management applications‟ databases. It also provides a map of the managed network on which various network objects are displayed, such as Subnetworks, Nodes, Links, etc. Performance Monitoring is also issued by the MS-GUI.


The Alarms application is the single common fault management GUI which provides presentation functions for the alarm of all managed NE‟s and network. The GUI presents a dynamic view of all current and historical alarms in the managed network. Besides the Global Alarm Management, which consolidates all the NE‟s elementary alarms and SNCP switching events and the network correlated alarms of the whole system, the user can choose to start the applications dedicated to the alarms filtered per single application (EML, SDH, WDM, PKT). The NEAD_USM (Network Element Auto Discovery User Service Management) opens the GUI for the creation of the auto-discovered NEs. The Current Events log opens a GUI for handling the SNCP switch events for 1850TSS-100, 1850TSS-160/320 and 1830PSS.


In previous releases, Network Tools provided the “IP over OSI” tunnels configuration. In 1350OMS R9.5, the “IP over OSI” tunnels configuration is available in MS-GUI.


The Task Scheduler enables the administrator to schedule the execution of jobs that typically include backups of data, purges of data, clean ups of data, and PM data collection. The System Monitor is the graphical interface that allows the user to perform process monitoring functions (start, stop, view the status, view the traces, etc.) on items that appear in a tree structure.


From the Process Monitoring and Control window, administrators can view and perform process monitoring functions on items that appear in a tree structure on the left of the window, directly below PMC. The slide displays: The Node item is made up of three icons and a node label. The node label displays the host_name or the IP address of the machine where the Process Monitoring server is running. The System Instance consists of an system instance icon and a label. The System instance icon displays the state of the application. The label displays the name of the application and its instance which is defined in the Process Monitoring configuration. The run level (RL) is also displayed. The Process Group is made up of one icon and a label. The label displays the name of the Group as defined in the Process Monitoring configuration. In this case Emlims. The Agent is composed of one icon and a label. The icon displays state of the Agent and the label displays the name of the Agent as defined in the Process Monitoring configuration. The Information area displays the application instance name and current state. From a global perspective, the System Monitor GUI enables the administrator to retrieve and to view information about the functional state of the machine on which an Application_Instance is installed and managed. In addition, the System Monitor enables the administrator to issue commands to the machine for the managed Application_Instance along with its respective and/or selected items. Consult the Alcatel-Lucent 1350 OMS Getting Started Guide, for additional information on Processing Monitoring and Control.


The Backup and Restore applications allow the administrator to dump and restore a copy of the application data to a disk or a tape. Examples of jobs: •Ntw: which is all management system data and NE backup data, meaning, network data •AS: which is all alarm surveillance data •PM: which is all performance monitoring data

•Swdl: which is all data pertaining to NE software downloads •Log: which is all log file data •System Configuration: which is all system configuration data •Operator: which is user data that includes the home directory of all created and predefined 1350OMS-EML users

The NE SW Packages allows the administrator to install on the EML the NE software packages to be downloaded to the NEs for possible upgrades.


There are three GUIs associated with the 1350 OMS Administration application which is used to administer and maintain user security throughout the 1350 Optical Management System. These GUIs include User Session, User Accounts, and User Profiles. These three Security Administration GUIs are explained in detail in the 1350 OMS Administration Guide, Vol 2: Common GUI Functions.


User preferences are customized attributes of the main windows, such as position, size, visible areas, and area size . These preferences are saved in the in the User Data Manager server for later reuse. User preferences may also be viewed and customized from the Tools > Options command displays the Preferences window.












The MS-GUI presents maps, lists, queries, and graphical views of network‟s objects. It provides a central point supporting comprehensive functional navigation across the whole managed network. The MS-GUI is the unique interface to access to the features of all the Element Management (EML) and the Network Management (SDH, WDM, PKT, SONET) applications of the 1350OMS. The Map of a network is a graphical view of the network upon which various network objects are displayed (e.g. sub-networks, Nodes, and Links). The Map enables the user to perform actions on these network objects, such as, creation, modification, deletion, retrieval, and provisioning. From the map of the MS-GUI the user is able to: 

View all nodes and physical links between them, animated by their alarm status



Retrieve lists of network entities



Organize nodes into recursive sub-networks, so having a partitioned map view of the managed network (see the Module “Map Management”)



Use menus contextual to the selected entity and the user profile



Start the provisioning wizards


The Map enables the user to perform actions on these network objects, such as, creation, modification, deletion, retrieval, and provisioning. The left panel is a hierarchical tree composed of the main (root) network, sub-networks at the various levels and a second level toolbar. The Map Contextual menu is composed of icons that are active at the opening of the map and icons that are dependent on the selected object.


The GUI server connection status synthesis icon shows if all the GUI servers are connected (plug close) or if some of them are disconnected (plug open). If a GUI server is disconnected, the execution of its operations is not available or fails. Unavailable Menu options will be grayed out. The PC Date and Time is displayed. This is not the 1350OMS server‟s date and time. It is necessary for the PC‟s date and time to be aligned to the server, so that the difference is lower than 5 minutes, otherwise some applications (e.g.: Processes Monitoring and Control GUI) will not start and/or will not work correctly.


The slide displays the Graphical Routing display which provides a pictorial representation of a managed connection including the NEs. ports, connections, alarms and directional and protection scheme. There are two other types of Routing Display windows: 

The Server Routing Display is a pictorial representation that displays the underlying optical connections.



The Text Routing Display presents the same information as the Graphical Routing display in text format.

The Reload icon is used to refresh the Routing Display from the application database after a change has been performed on the ports menu or when fault conditions change. There are many icons associated with the Routing Display. A mouse over of the icon provides a tooltip describing the purpose of the icon (directionality, protection type, alarm level etc.). The Connection Icon symbol varies depending on the whether the Routing Display is for a Physical, Trail or Path Connection. The connection name is displayed beneath the icon. The Connection icon is color coded to the connection configuration state: pink indicates that the service has been defined but provisioning is incomplete, lime green indicates that the provisioning is complete but the service has not been activated and sea green indicates that the connection configuration has been activated. The Network Element icon is represented by a color coded rectangle. Managed NEs with no fault indicators are represented by a green rectangle. Non-managed NEs (ENEs) are represented by a gray rectangle and NEs in maintenance or experiencing a loss of communication are represented by a magenta rectangle. Note External Network Element (ENE) is a set of NEs that are outside the managed domain. These may represent non-supervised adjacent sub-networks or Customer Edge devices.

The NE port icon is a square containing two triangles and is located to either side of the NE rectangle. Each port is labeled with the address of the port. Ports are color coded to indicate the highest severity alarm on the port. All Rights Reserved © Alcatel-Lucent 2012 1350 OMS WDM Operation and Maintenance Page 67

At the bottom left of the window are two Log icons: Servers log provides a list of the type and the connection time of all servers. Operations provides a list and description of all operations that have been performed by the user. The description covers the following information: Operation, Involved Object (performed action), Status (executing, completed, failed), Start-Time, and End-Time. When an Operation is selected from the list, it is possible to see the Filter, Details, and Parameters. This is helpful in the resolution of failed procedures.

By the Search Menu the user can retrieve lists of the network‟s objects and information related to the power adjustment procedures on WDM NEs. In addition, the Performance Monitoring domain can be accessed. Because query options for the Search command are dependent on the 1350 OMS installation parameters. Menu options may vary for individual applications and systems. OTN: commands for 1350OMS-SDH Packet: commands for 1350OMS-PKT


From the Actions Menu the user can: 

Perform tasks on the network‟s objects (create, delete, discover, synchronize, …)



Schedule jobs on File Transfer Scheduler



Set the Performance Monitoring (PM) report options



Retrieve and modify objects properties, etc.

Because query options for the Actions command are dependent on the 1350 OMS installation parameters. Menu options may vary for individual applications and systems.



Using the Find operation, the user can search the information that appears in the Main View panel. A Sub-network is an arbitrary collection of ports into a group. Each sub-network is linked up with a sub-network or with the main network. A sub-network contains other sub-networks, NEs and/or ENEs. Typically sub-networks are defined to include entire NEs, but is not a requirement. The Parent sub-network of a sub-network (or a NE or an ENE) is the sub-network that contains it.


The Search icon located on the tool bar at the bottom of the left tree panel allows the user (with or without a list being displayed) to locate a specific item on a list based on user provided criteria. The Contains field is optional. You can enter text information in this field to limit the search operation. The Advanced area of the Search Criteria panel is optional and can be performed with the initial search or after the initial search has been executed. The Reset icon refreshes the Advanced area. The More icon opens and additional filter panel.


Search for specific criteria in a system-generated list by applying filters to your search action. This filtering is only performed for the displayed list.


You can also search for specific criteria from a system-generated via the filter (Change Search Criteria) icon on the toolbar at the top of the list. Remember to click on the Modify icon to initialize the filter panel.


You can perform a search from the query area beneath a list. The first graphic displays 18 objects in the All Paths List with zero objects selected and no filter applied. When you type search criteria in the filter bar (in this case DSR), 1350 OMS will automatically filter out all objects that do not meet the criteria provided. The second graphic displays this filtered results. Deleting the search item from the filter bar, returns you to the original list (i.e. all Paths and rates are displayed).


The Windows Manager mode icon on the left tree panel allows navigational functionality among the open windows. In the left panel, a hierarchical tree is displayed that lists the MS-GUI open windows grouped by category. Select an item from the list and click on the Undock icon in the Windows tool bar. The Window can be sized, and moved around on the screen. To dock the window, click on the Dock

icon.


Using the Windows Manager, Undock icon, you can also split the screen between two open windows. This is useful for viewing more than one list at one time. To return to the original window format, double click on a list title bar.


When the Operations icon is slected a hierarchical tree is displayed in the left panel. Selection of this icon enales shortcuts to certain operations to be displayed in the left panel. The GUI provides commands that are pre-loaded with the system. You can also define your own categories and populate them with their own preferred commands. The commands that are placed in the tree cannot be customized. For example, a shortcut for a list runs the list request without filters.

To remove an added category, select the category from the Remove Category drop-down menu a confirmation message will be displayed. Click on “Yes”.


When the Favorites icon is selected, the left panel switches to the Favorites mode. The Favorites mode allows you to display a hierarchical tree in which user defined bookmarks are listed. Each bookmark is composed of a set of query or search operations that can be stored with filters and options.


To delete Favorites, highlight the Favorites item to be deleted and click on the “Remove Selected Favorites icon. A confirmation message box is displayed, click on “Yes”.



The slide displays all of the icons associated with the First Level Toolbar. The First Level toolbar is located under the Main Menu and contains icons representing non-contextual functions. The toolbar is composed of icons which are independent of the selected object instance and icons that are dependent on the selected object instance. The independent icons include: The Enable Filtered Searches allows the user to enable or disable the filter for the Search operations. If this button is enabled and the user launches a retrieval operation using the Search menu, the system provides an additional window from which to set the filter criteria for the selected object class to be retrieved.

The Operate in Normal Mode icon allows the user to switch between normal and advanced profile. The profile can only be applied to the open windows related to the list view and Physical Map categories. The advanced profile includes all commands related to the active window. The Help for active view icon provides access to topics on MS-GUI navigation. The Backward icon returns to the previously selected window. The Forward icon proceeds to the next selected window list.


Reload Data reopens the Map related to the involved sub-network. Zoom Best Fit modifies the object sizes and the background picture size so the entire sub-network appears in the Main View panel. Normal Size restores the default dimensions of the objects and the background picture on the Map. Change Background changes the background picture of the Map. Before changing the background, the system allows the user to preview the available background pictures from a pop-up “Background Selection” window. Go to the parent view allows the user to view from the current Map the associated sub-network and/or network to which the current view is linked.

Save Map Configuration saves the background picture and the position of the objects on the Map. This feature does not save any modification to the original size of the objects and background picture when the Zoom in or Zoom Out are used. Technology options are dependent on the applications installed in the server. Layer options are dependent on the selected Technology.


Dependant icons rely on the selected layer and object instance therefore, Dependent icons will vary based on the current map view and the object selected.


A list is a presentation form that is displayed as a result of a query request from the user. Lists are displayed in tabular format. You can move the columns of the table forward and backward in the list. Click on the Reload Data icon to return the table to the default settings. A right-click on a column header provides a contextual menu used as a shortcut to the possible commands and queries of a selected object. The table data may be exported as a .CSV file to your desk top. The modified table may be saved upon exit of the MS-GUI by answering “Yes” to the “Do you want to save working session before exit MS-GUI?” message box.




































This section presents an introduction to the 1350 OMS WDM functionality and its relationship to the Element Management Layer (EML). Futher discussion of the functionality depicted on these slides will be discussed in more detail throughout the course.


When a Q3 interface is used, the NE needs to be configured with a NSAP OSI address. When a SNMP or TL1 interface is used, the NE needs to be configured with an IP address.

Note This module will discuss the creation of an 1830PSS (4G TL1) NE. The 1350 OMS EML R 9.6 Operation course (TOS63017) provides creation procedures for the different families of equipment based on their management interfaces (Q3, TL1, SNMP, Q3 CNA etc.).


The SID is known as the Target Identifier (TID) in 1830 PSS. The SID/TID is composed of a string of up to 32 (for ETSI) and 20 (for ANSI) non case-sensitive alphanumeric characters, including the hyphen (-) character or a quoted string up to 32 (for ETSI) and 20 (for ANSI), including any special characters. In the non-quoted string, the SID/TID must start with a letter and end with an alphanumeric character. Consecutive hyphens (-) are not allowed. The number of hyphens used in the string must not be greater than four. The OSPF routing for the OAMP port should be set to redistribute if the routing table of the Gateway NE is not to be advertised externally.







OSPF Areas is for an OSPF configuration where automatic routing is required. OSPF is a form of dynamic routing which uses a routing table to determine the best route path. Static routes are routes through a data network described by fixed paths (statically).


This slide and the next two slides focus on the creation and addressing of an 1830 PSS without security.



The NE can connect to the Network Element Management System (EMS) via the OAMP port if it is configured to act as a Gateway Network Element (GNE). The IP address must provisioned and the OAMP port enabled to use this port. In addition, and IP route must be established to route connections to the Remote Network Elements (RNE).

Check the correct configuration and process status with the System Administrator.


If the operator doesn‟t select the Supervision Area and the EML Domain, in the above procedure, EML will automatically chose these two parameters. The system takes account of each available “EMLIMSNA” and tries to make their load homogeneous. The Directory Field refers to the Physical Network Management GUI server (PNMIM) of the EML instance in which the NE must be created. Normally there is only one EML instance installed in 1350 OMS and the field is automatically completed with the proper value. If more than one EML instance is available, the operator must select the desired PNM GUI Server from the drop-down list.



The GNE Flag enables a TL1 command line interface operator to act on a Remote NE (RNE) through a Telnet access to he Gateway NE (GNE). This feature is applicable only to the ANSI environment. If the “FTAM” parameter is set to “Use GW”, the NE under creation can be used as a repository to download the SW to its Remote NE. This feature will be available in future releases. The TID (Target Identifier) i.e. the NE identifier used in the messages exchanged between the NE and the EML, must be equal to the “System IDentifier” (SID) set into the NE. 

SID (or TID) is a string of up to 32 (for ETSI) or 20 (for ANSI) non case-sensitive alphanumeric characters, including the hyphen (-) character, or a quoted string of up to 32 for ETSI (20 for ANSI) characters, including any special character. If it is a non-quoted string, SID (or TID) must start with a letter and end with an alphanumeric character. Consecutive hyphens (-) shall not be allowed. Number of hyphens shall not be greater than four.

The NE address can be modified only if the NE is not supervised (i.e. in the "declared" state). The SNMP address setting is not required.

Note For the creation of 1830 PSS NEs, the GNE/RNE flag setting is not critical and should be left in the default state. 1830PSS GNE/RNE roles are defined at the IP DCN level and transparent to 1350 OMS. 1350 OMS treats all the PSS NEs as GNEs. However, the GNE/RNE flag is critical for other NE types thought. For example correct settings are mandatory for TL1 NEs.


Prior to starting supervision, check to see if the NE is reachable. 

Ping (Packet Internet Grouper) tests the DCN parameters (address, DCC, LAN interfaces etc.)



Supervision tests the supervision rights

The Ping NE function of the Telecommunication Network Management OS enables the administrator to test the communication link with an NE. The Ping NE function is managed by the Middleware Interface (MW-INT) application, which is the platform on which the 1350 OMS is built.



Supervising NEs is an essential aspect of the network management. It enables the gathering of information concerning the behavior of the NE with respect to its functional state. The supervision of an NE consists in establishing a communication that allows the user to perform EML operations such as configuration and alarm management. The NE address must be declared before starting the supervision of this NE. After supervision is started, the “Supervision State” attribute changes from DECLARED to SUPERVISED.




All the procedures on networks and sub-networks described in the present Module can be issued as well from the MS-GUI networks and sub-networks lists. To open the network list: “Search  Map  Networks” (only ROOT is shown). From the ROOT object in the list it is possible to create sub-networks (“Actions  Create Sub-Network”) or list the first-level sub-networks (Search  Sub-Networks). From the Sub-Networks in the Sub-Network lists, it is then possible: 

To search the contained Sub-Networks or other Physical or SDH (OTN) objects.



To create a new contained sub-network.



To modify (or even delete) the selected sub-network


“ROOT” is always configured by default as the root network under which all managed sub-networks must be created, based on the desired hierarchy. “ROOT” cannot directly contain nodes.



If the creation is successful, the header window of the Create Sub-network panel turns green for success; red indicates a failure.

The operator is optionally allowed to enter a filtering criteria defined in terms of a list IP Address/Mask pairs. Only the filtered list of NE belonging to the “subnets” defined by any of the masks will be given back to the GUI. In case of the operator is not filling in any filtering criteria, the discovery scope will consist of the overall subset of 1830PSS network elements that are reachable from the NE where the action is triggered.


The discovery process can last several minutes, depending on the number of NEs to be discovered. Location Name and Supervision area are populated based on the gateway NE by which the process has been started. In the case of an „Abort‟ request, the NEs discovered up to the time the discovery was interrupted can be created by clicking on “Next”.


The address and User ID and password of the auto discovered NEs are automatically set during the discovery procedure. 

Address is set based on the info sent by the discovered NEs.



User ID and password are the same as the ones of the Gateway NE.

Eventually change the location name, check NE IP address, User ID and password, and start supervision.

































Deletion of Correlated Cross Connections is not allowed. Uncorrelated Cross Connections may be deleted. Fixed cross Connections can neither be created nor deleted. Inconsistent Cross Connections can be reconciled.



A cross connection with a state of “partial” can result from: • Deletion of a Cross Connection from the NE Cross Connection Page which partially fails • Create/Modify/Delete of a Cross Connection on a Network Connection Provisioning Order partially fails



Only correlated cross connections have a Connection Name displayed in the list. Correlated Cross Connections cannot be manually deleted.
























Depending upon the status of the ASAP (enabled or disabled) the following occurs: • If ASAP is currently enabled, Manual Disable ASAP is available • If ASAP is currently disabled, Manual Enable ASAP is available




Inconsistent Trails or Paths with SNC Mismatches, Parameter Mismatches, and ASAP Mismatches can be acknowledged.


















Internal Optical Section (OS) - is a physical fiber connection that is provisioned within the NE and established as bidirectional connections either automatically by the NE when it detects a valid signal, or explicitly through a TL1 command. The OS connection can be either discovered, provisioned by the user, or created by the user during Path/Trail connection provisioning in 1350 OMS as Optical Sections. External Optical Section connections are physical fiber connections configured between two nodes (a physical connection between the TDM NE OC-n port and the WDM OT client side port). Internal Optical Transmission Section connections are physical connections between 1830 PSS Nodes. These connections are created in EML and auto-discovered in WDM based on the connection tables of the NEs. External Transmission Section (OTS) connections are physical fiber bidirectional connection between two high speed lines of DWDM NEs which consist of two unidirectional fibers making up a bidirectional connection. These can be discovered ONLY.



The Job Updates window is used to view the progress of orders created, and monitor background tasks that are running. The Job Updates page can be left open while tasks are performed so that the progress of each connection can be monitored.


Connection Panel options: Configuration Rate; OS, OTS Source Type; Not applicable Protection Type; Unprotected, Protected Connection Shape; Simple (bi), Double Simple (bi), Simple (uni) Domain Type; NA Name Format; Free Format, Telcordia, M14000 (If Telcordia or M1400 are selected, additional fields are displayed for input). Connection Name; 83 character name for the connection following Name Format rules (Telcordia, M1400 or Free Format Connection Alias; 83 character alternative name for the connection (optional)



The Supplemental Panel is only displayed for WDM Physical Connections. The VA port field is applicable only for 4DPA4, 11DPE12 and 11QPA4 circuit packs. For all other circuit packs select NA. For keyed service on the 4DPA4 circuit pack select the eVOA port on the OT which will provide the Wavelength Tracker encoding (WTE) and monitoring functionality. For unkeyed service on the 4DPA4 circuit pack select NA. For the 11DPE12 and 11QPA4 circuit packs, if an optional sVOA port on the OT will be used to provide attenuation and monitoring for DWDM configurations select the sVOA port in the VA port field. Otherwise select NA. For CWDM configurations select NA.

VA1 and VA2 ports are applicable for 4DPA4, 11DPE12 and 11QPA4 circuit packs. VA3 and VA4 ports are applicable only for the 11QPA4 circuit pack.


Most of the Performance Monitoring (PM) options are self explanatory. In the 15-minute PM and 24-Hour PM fields selecting “Yes” from the drop-down menu enables the subsequent fields. If “No” is selected the fields remain inactive. You can select both 15-minute and 24-hour PM data collection on this panel.


Starting in 1350 OMS WDM R9.5 the Transmission Parameters shall be displayed if for the selected connection rate and service type any one of the end points supports the parameter. As with this scenario, if one of the end NE/port supports a transmission parameter (11DPE12-1-7-L2) but the other end NE/port does not the system will send the command to the NE that supports the transmission parameter.

Note If the user types in the NE name on the End Points panel instead of selecting it, the transmission parameters panel shall not be enabled. I.e., the system shall treat the scenario as “use NE values”.


Order Panel parameters: Order Number – Is a unique number that identifies the order. This is an optional field as you can either manually enter an order number or allow 1350 OMS WDM to generate it. Order Step - During its life, an order goes through a list of successive steps (Defined, Allocated, Implemented or Commissioned). 1350 OMS WDM validates the connection and then moves it through the steps of the order management process. Order Type - Each order type corresponds to a type of provisioning task (Add, Discover, Delete etc.). Due Date - The date and time the Order completed and moves to the Commissioned order Step.

Ignore Alarm For Completion - The possible values are “Yes” and “No”, with a default of Yes. Pertains to the movement of an order from the Implemented to the Commissioned step. If Yes, no special processing will be performed. If No, any alarms on the end ports or any fault states other than (Working) on the direct servers of the object will prevent the transition to the Commissioned step and the order will remain in the Implemented step. Comments – Manually enter any notes associated with the connection. This is an optional field.

Technical Reference Consult the Alcatel-Lucent 1350OMS WDM Guide, Order Management chapter for additional information on the topic being discussed.



The Job Updates window is used to view the progress of orders created, and monitor background tasks that are running. The Job Updates page can be left open while tasks are performed so that the progress of each connection can be monitored.


Connection Type – Select the connection type (e.g. SDH (default), WDM, SDH,SDH/WDM/Interworking etc.). Transport Alarm Enabling Rule – On Definition, On Implementation, On Set in-service, Manual Implement Rule – Automatic, User Allocation Cost – Physical connection cost used in the routing algorithm (range is 0-100). This is the nominal cost of the physical connection which will be used by the allocation algorithm (Dijkstra static). Allocation sets a cost threshold and is used to limit resources exceeding the upper threshold. Show created Physical Connection – (Yes (default) or No) If the user selects “Yes” after creation, a view containing the created physical connection will automatically appear.


You must click on the selection icon to the right of the “A Node” field to generate the selection options. Selection options: Nodes for Physical Connection creation (Filtered) – provides a filtered list from which you can select a specific Node.

Use this option, to filter the “Node” list based on your criteria. Clicking on the “Ok” button of the Filter form presents the “Node” list displaying only those nodes that meet your criteria. From the “Node” list highlight a node and click on “Ok”. Nodes for Physical Connection creation – provides the entire list of available nodes. Select the desired node from the “Node” list and click on “Ok”. This is the option displayed in the slide.



On the successful submission of the creation request, the status bar of the Create Physical Connection wizard will turn Green. The order to create a physical OTS connection is processed. 1350 OMS will automatically provide the Order parameters such as order number, date and time, and completion information.



OTS graphical view presents the list of supported lambdas (LC at OCH layer) and for each of them the related (if provisioned) OTU trail and supported DSR path(s). This graphical view summarizes in a single window the OTS/OS link characteristics suc as: OTS alarms OTU trail name, state and alarms Used and free channels(frequencies) Related services (DSR paths) state and alarms

Technical Reference Consult the Alcatel-Lucent 1350OMS WDM Guide, Internal OS Physical Connections chapter for additional information on the Physical Connection Structure graphical feature.












The slide features the creation of a CWDM OTUk Trail using the Double-Simple (uni) connection shape to illustrate the complementary port pairs concept.




Connection Rate – OCH (default) ensure that you select rates that are based on the circuit packs capability. Service Type – Not Applicable for trails Routing Field – Automatic, Manual, Cross Connection Based, in this example we have selected “Automatic” hence we select the “Automatic” tab in the routing panel. Protection Type – only appears in Automatic routing Automatic Provisioning Server Layer – the system automatically provisions the server layer (Och, OTUk, ODUk) when a client is provisioned. Automatic provisioning of the server layer is not available for all NEs. Connection Name –138 character string (optional) If you do not specify a connection name, 1350 OMS WDM will automatically generate one. Connection Alias – 138 character string (optional) Server Rate – must be compatible with the Connection Rate.


Section 4, Module 1 Physical Connections provides an explanation of the End Points panel.


Transmission parameters have two behaviors: 

AZ trail trace parameter will be displayed only if both the From NE, and To NE support AZ trail trace for that connection rate and service type (same for ZA trail trace).



The Payload AZ trail trace parameter will be displayed only if both the From NE, and To NE support Payload AZ trail trace for that connection rate and service type (same for the Payload ZA trail trace).



Other parameters will be displayed only if one of the end NEs supports the parameter for that connection rate and service type.

Starting in 1350 OMS WDM R9.5 the Transmission Parameters will be displayed if any one of the end points supports the parameter for the selected connection rate and service type. In previous releases the parameters were displayed based on the From Port ID1 port only.



The Routing Effort field drop-down menu contains two options. Best Effort (default): ●

The system will at first attempt to find a route with the protection type selected by the user.

●

If a route of the requested protection type is not found, the system will find a higher or lower protection type.

●

If necessary, the protection type selected by the user will be updated by the system.

Enforce Protection Type: ●

The system will attempt to find a route with the protection type selected by the user.

●

If a route of the requested protection type is not found, the system will reject the provisioning request and send an error message.

The Ignore Alarm For Route field is only visible when the routing mode is Automatic. This option is used by the system to move a network connection from the Defined step to the Allocated step (find the route). The drop-down menu contains two options. ●

Yes- the system will not consider the fault state of the direct servers to find the route.

●

No (default) - the system will select only those link connections whose servers are not alarmed.



Port Constraint Node Name – allows you wish to include a Port as a routing constrain by selecting the node that contains the port.


You can also populate the Auto Routing Constraints Table using the “Send To” menu item when you have a list of Trail Connections, Link Connections and Nodes.


When Alarm Enabling is set to “Not Set”, no Alarm Severity Assignment Profile (ASAP) is set on the connection. When set to Enable, the ASAP on a connection implies that the alarms are reported by default based on the ASAP rules for that particular path/trail/physical connection. When set to “Disable”, the ASAP is set to “None” where no alarms are reported and all alarm severities are set to “Not Reported” (NR). This feature is not available for all Network Elements, Enabling or Disabling ASAP could take several minutes to complete. Alarm Severity Assignment Profile is the function that allows the assignment of severities to the alarms depending on their probable causes.

Note Check the Job Updates window and the Operations log for completion information.












Note Check the Job Updates window and the Operations log for completion information.




Oder Sensitive – indicates whether or not the exact order of the selected links should be used when using fully constrained routing (manual routing). This will be discussed in detail later in this section.


Show All Link Connections - allows the user to view all of the link connections with system link ownership independently of the link connection state. No indicates that not all links are shown. The Link Connection Selection window displays only the link connections with system link ownership in the Available or Connected link connection state. Yes indicates that all links are displayed.















































The Optical Data Unit1 (ODU1) may be multiplexed into an ODU2 or ODU3 (e.g. 4 ODU1s = ODU2, 16 ODU1‟s or 4 ODU2s = ODU3). The termination of the OPU, ODU and OTU is performed at the electrical level as referenced by ITU-T G.709. The termination of the Och, OMS and OTS is performed at the optical levels as referenced by ITU-U G.872.




Y-Cable Protection is also known as Optical Sub-Network Connection Protection.



The graphic does not display the Z end which is between two routers.

On the graphic, following the left to right signal path, an unprotected client signal is passively head-end bridged by the Y-cable to a pair of redundant transponders. 

Each transponder transmits a WDM line signal onto a diversely routed fiber. One signal is the primary, and one signal is the secondary. At the far end, the primary and secondary signals are received by another pair of redundant transponders. 

The transponder receiving the primary line signal converts it to a client signal and passes it through the Y-cable to the client equipment. 

The secondary transponder has its client interface turned off. In the event of a primary line fiber cut, primary transponder failure, or primary signal degrade, the primary transponder in the failed path will disable client signal transmission and the secondary transponder will turn on its client signal transmission. 

A major advantage to O-SNCP vs. using an OPS card is that the transponders perform the switching. Because the transponders are O-E-O devices, protection switching can be triggered by digital performance monitoring. 



Four OS connections will be created: • An OS Connection between the Working Port on the A End Y-cable circuit pack and the OTU client port selected by the user as the A End Working Port • An OS Connection between the Protection Port on the A End Y-cable circuit pack and the OTU client port selected by the user as the A End Protection Port • An OS Connection between the Working Port on the Z End Y-cable circuit pack and the OTU client port selected by the user as the Z End Working Port • An OS Connection between the Protection Port on the Z End Y-cable circuit pack and the OTU client port selected by the user as the Z End Protection Port.

Note: When a DSR/ODUk path with Y-Cable Protection is deleted or canceled, the OS will not be removed.


The protection capabilities supported by the 1830 PSS-36/PSS-32/PSS-16 OTs is detailed in the following table.




If the user selects any value except Use NE Values for the Signal Type, the From and To Optical Transponder Working and Protection Ports, must be assigned with the user selected signal type. If the user selects any value except Use NE Values for the Signal Type, the From and To Optical Transponder Working and Protection Ports, must be assigned the same signal type.







Following the left to right signal path, an unprotected client signal is converted to a WDM line signal by a transponder. 

An Optical Protection Switch (OPS) pack is inserted between the transponder and WDM filter. 

The OPS head-end bridges (passive optical splitting) the line signal to a pair of diversely routed fibers. 



At the far end of the network, the two line signals are received by the far-side OPS.

The OPS switches (optically) a valid line signal to the far-end transponder, which forwards the signal to the far-end client. In the event of a line fiber cut on the working path, the far-end OPS switches to the alternate signal. 



The switching criteria is based on loss of optical power.

The OPS also monitors the health of the protect path so that if there is a fiber cut, the signal will be switched to a known good path. 

The reverse path operates in the same but independent manner, i.e., the OPS supports unidirectional switching. 

The 1350 OMS WDM operator selects Optical Transport Service endpoints and defines the service protection type to be OPSA protected via a Create wizard. 




Ensure the 1350 OMS WDM application can communicate with all NEs in the connection. Open the Job Updates window to monitor the status of the added connection.






Check the Job Updates and Operations windows for order completion.




Note Working and protection ports must have the same port number. Ex. OPS-2-5-SIG

See Section 4 Module 2 “Path and Trail Connections”: Create a Path w/Walker routing for an explanation of the “Order Sensitive field.









The OT performs single channel OEO to translate the CWDM signal to an electrical and the electrical signal to a DWDM signal. When a connection has CWDM-DWDM regeneration multiple OTUk trail connections are required for a single DSR/ODUk path connection. Separate OTUk connections are required for each CWDM and DWDM portion of the connection. An OTUk connection must be terminated whenever the optical signal is translated to an electrical signal at a circuit pack performing OEO regeneration. If a connection performs CWDM-DWDM regeneration two OTUk connections are required. Each OTUk connection carries a pair of transmit and receive frequencies for the CWDM Single Fiber in our example. CWDM and DWDM support different frequency ranges and the frequency of the connection must change during CWDM-DWDM or DWDM-CWDM Regeneration. For the DWDM OTUk connections a connection shape of Simple (bi) is required. For the CWDM OTUk connection, Single-Fiber a connection shape of Double Simple (uni) is required. The DWDM OTUk connections may be keyed or unkeyed. The CWDM connections must be unkeyed. All OTUk connections composing the DSR/ODUk path connection do not have to have the same value of keyed/ unkeyed.


NPR – the Network Physical Resource is part of the 1350OMS-EML application. It manages network construction and inventory on physical resource (i.e. NE, boards, ports). It provides support for manual/automatic physical link creation.
































DSR - Digital Service Rate, a layer rate that carries either SONET signals, or data services.














electrical Variable Optical Attenuator (eVOA) - Works with the Tap module to provide input for Wavelength Tracker modulation and provides optical tap for feedback signal to the Wavelength Tracker. Orthogonal coding - provides the ability to make changes in isolated areas of code with minimum impact to other parts of the system.
























































The Green field commissioning process flow is described as follows: 1.

The 1350 OMS user initiates a request to start commissioning from the integrated GUI. The user will receive a prompt to select an already transferred, (through FTP), EPT file.

2.

The CPB will obtain the IP addresses and other SNMP parameters from the Physical Network Manager (PNM) by means of a DB View.

3.

The CPB will do the necessary discovery and validations and will implement the commissioning and set the optical parameters specified in the EPT file.

4.

In case of errors, CPB will notify the GUI server and the user will be notified.

5.

When commissioning has completed, CPB will send a completion notification to the user through the GUI server.






The “CPB Plan File Upload Page” is shown in an Internet Explorer window .















ASE Commissioning – commissioning process using inter and intra-node losses to set amplifier gains and expected per-channel powers at various Wavelength Tracker detect points.






Coloring is used to indicate normal, abnormal conditions in the egress and ingress components. Yellow highlighting indicates suspect component. Red highlighting indicates defective component. The Loss Report, when displayed to the user, can be saved locally in the client PC or sent to a network printer.



























Counter Summary– groups alarms according to user defined filtering criteria Sublist Content– shows all the alarms according to the sublist selected by the user Sublist Counter –The Sublist Counter area is composed of a table that displays the counters showing the total alarms for the sublist selected in the Counter Summary table. Pagination area – allows the user to adjust the number of alarmed rows viewed at one time (max = 200) Message area – displays commands as they are performed.



















Reservation ensures that only one operator is responsible for an alarm. An alarm can be reserved only if it has not been reserved by another operator. To unreserve an alarm follow the procedure on the slide however click on the “Unreserve” icon on the Main toolbar.



To un-reserve an assigned alarm, follow the procedures on the “Reserve an alarm” slide however click on the Unreserve icon on the Main Toolbar.









































This feature is not available for all NEs. Enabling/Disabling ASAP can take several minutes to complete.
























Auto Purge – Automatic purge of measure (True/False) Collect Counter – counters belonging to the granularity period will or will not be collected (True/False). False indicates that the historical data counters will not be collected, even when the measure is activated. This implies that the goal of the measure is set to Threshold Crossing Alert profiles on the termination points.
