3 Disabling Service-Affecting Settings Automatically

Disabling Service-Affecting Settings Automatically

This section describes how to disable the service-affecting settings automatically. Serviceaffecting operations, such as loopback and laser shutdown, can be automatically disabled. That is, when the time for performing a service-affecting operation exceeds a certain period, the operation is disabled automatically.


Impact on System l

If a port is the only way that an NE communicates with the U2000, performing loopback or laser shutdown at the port will result in loss of communication. Before performing loopback or laser shutdown, you must set automatic disabling for this NE. Otherwise, after the communication is lost, you cannot use the U2000 to log in to the NE to disable loopback or laser shutdown.

l

The IPA function is used to shut down lasers on OA boards and Raman boards when a fiber is cut, so as to avoid personal injuries. For security reasons, Auto Disabling for IPA Disable can only be set to Enabled.

l

Disabling service-affecting settings automatically does not apply to WDM-side lasers on the PID board.

Prerequisites You are an NMS user with "Maintenance Group" authority or higher. The correlative board must be created.

Impact on System None.


Background Information FEC is the short for forward error correction. The optical signals undergo quality degradation during transmission, which may lead the receiver into misjudging "1" for "0" signal or "0" for "1" signal. The FEC adds the parity bits during coding by the transmitter so that the receiver can correct the error bits in the code stream by calculating the parity bits.

Querying the FEC Mode

This section describes the basic method for querying the FEC type. There are two FEC types: FEC and AFEC.




Background Information The OTU board or line board uses FEC and AFEC (Advanced FEC) technology to perform the following functions: l

Decrease the requirements on the receiver optical signal-to-noise ratio (OSNR) in order to extend the transmission distance between optical amplifiers or between REGs.

l

Provide a greater system margin and guarantee a lower BER rate in the line transmission to improve the quality of service (QoS) in the DWDM network.

The AFEC is a new error correction technique. It adopts two-level encoding, increases encoding gain, and equally distributes the burst errors. AFEC is more powerful than FEC.

35 Setting Alarm Reversion

35

Setting Alarm Reversion

In the process of deployment, certain alarms that are reasonable but meaningless occur. For example, when you configure a board for a service but not connect cables, the corresponding LOS alarm is generated. After the alarm reversion is set, the alarm is not displayed. This does not affect the network monitoring that is performed by maintenance engineers.


Background Information The setting of alarm reversion is applicable to only LOS alarms, including the R_LOS, MUT_LOS, OTS_LOS, OTS_LOS-O, OTS_LOS-P and OSC_LOS alarms. If you set alarm reversion for a port, the status of all alarms at this port is displayed as "no alarm" even though the alarms occur.

Impact on System l

When you set the alarm reversion for a port, the alarm status on this port is opposite to the actual situation. That is, alarms are not reported even if they exist.

l

When you set the alarm reversion for a port, the alarm status of the board does not change, and the alarm indicator still indicates the actual running status of the equipment.


Setting Alarm Reversion 1.

In the NE Explorer, click the NE and choose Alarm > NE Alarm Attributes from the Function Tree.

108



Precautions

NOTICE After changing the NE IP by U2000: l

If the IP address of the NE and the IP address of the NMS server are in the same network segment, the communication between the NMS and the NE is normal. In this case, you only need to re-log in to the NE.

l

If the IP address of the NE and the IP address of the NMS server are in different network segments, the communication between the NMS and the NE stops. In this case, set a new IP address for the computer where NMS is installed to restore the communication. Ensure that it is in the same IP subnet segment as the original NE IP. Because of the restriction of the SQL database, after you have changed the IP address of the computer, you must shutdown the NMS client/server, restart the computer and start the NMS client/server again.

After changing the NE IP by Web LCT: l

If the IP address of the NE and the IP address of the Web LCT are in the same network segment, the communication between the Web LCT and the NE is normal.

l

If the IP address of the NE and the IP address of the Web LCT are in different network segments, the communication between the Web LCT and the NE stops. In this case, set a new IP address for the computer where Web LCT is installed to restore the communication. Ensure that it is in the same IP subnet segment as the original NE IP. After you have changed the IP address of the computer, you must restart the Web Lct.

57 Modifying the NE ID

57

Modifying the NE ID

The ECC protocol uses the NE ID as the unique identifier of an NE. Hence, you need to assign a unique NE ID to each NE when planning a network. If an NE ID conflicts with another NE ID, it causes an ECC route conflict and the NMS cannot manage certain NEs. During the commissioning or expansion process, when you need to adjust the original network planning and change NE IDs, you can use the U2000 or Web LCT to change NE IDs.



Background Information The master and slave subracks are displayed as one NE on the U2000. They share one NE ID and one NE IP.

Precautions

NOTICE l

Changing the NE ID is a dangerous operation, which may interrupt NE communication.

l

Before changing the NE ID, delete the service and function connected with the NE ID, for example, the protection group, IPA, ALC, fiber connection and so on. After changing the NE ID, reconnect the fiber connection and re-configure the protection group, IPA, ALC and other function connected with NE ID on the U2000.

l

Before changing the NE ID, delete the manually added monitoring relation between the WMU board and the OTU or line board on the NE. After changing the NE ID, restore the deleted monitoring relation on the U2000.

Issue 02 (2013-12-31)

97 Creating Fibers in the Synchronization Mode

Creating Fibers in the Synchronization Mode

After the equipment commissioning is completed, the fiber connections might exist on the NE. You can synchronize on the U2000 the internal fiber connection data of the NE with the U2000 side.

Prerequisite l


l


l


l

Before the creation of fibers, it is recommended that you set Planned Wavelength No./ Wavelength(nm)/Frequency(THz) of the port on the tunable OTU board or line board as the designed wavelength.

l

Applies to WDM equipment.


Background Information After the equipment commissioning is completed, the fiber connections might exist on the NE. You can synchronize on the U2000 the internal fiber connection data of the NE with the U2000 side. Conflicting fibers refer to the different fibers configured on the NE and U2000 sides. Click Synchronize and Create Fiber/Cable, and then the conflicting fibers are displayed in the Uncreated Fiber in NMS and Uncreated Fiber in NE user interfaces. The conflicting fibers cannot be synchronized between the U2000 and the NE. In this case, based on the networking design, delete the incorrect fibers. After that, click Create Fiber/Cable and re-create the remaining fibers. NOTE

The U2000 supports the ability to synchronize WDM fibers in batches. To do so: In the Main Topology view, choose Inventory > Fiber/Cable > WDM Fiber/Cable Synchronization from the Main Menu.

98 Creating OCh Trails by Trail Search

Creating OCh Trails by Trail Search

After you create fibers and configure services for WDM equipment on the U2000, the trail information does not exist at the network layer of the U2000. To manage OCh trails, search for the cross-connections and fiber connections data over the network to generate end-to-end WDM trails at the network layer of the U2000.

Prerequisite l


l

Fiber connections must be correctly created for the WDM equipment.

l

If certain cross-connections exist, you can create an optical-layer trail by using any of the following methods:

Precautions

– Delete the original cross-connection and create the optical-layer trail by using the trail function. This method affects services. – Complement cross-connections on NEs and search for the trail. l

You can create only single-NE optical cross-connections from the AM port to the OUT port of the RMU9 board and from the IN port to the DM port of the WSMD9/WSMD4/ WSMD2 board. In this case, the board optical cross-connection is not supported. These types of single-NE optical cross-connections do not impact services. You need to create these types of single-NE optical cross-connections and search for trails if you want to manage the services transmitted in the cross-connections by using the trail management function.


Procedure for the U2000 1.

In the Main Topology view, choose Service > WDM Trail > Search for WDM Trail from the main menu.

2.

Under Advanced settings, set the search policies.

Issue 02 (2013-12-31)


174


98 Creating OCh Trails by Trail Search NOTE

In the searching by subnet mode, the selected subnet range should be independent from the networking. That is, no fiber connection exists between the selected subnet range and the area beyond the selected subnet range.

3.

Click Next to begin the search for trails. The U2000 takes a while for searching, depending on the number of services. NOTE

l If there are cross-connections that are collisions and these cross-connections cannot form end to end trails, the U2000 shows the conflicting trails after you perform the search operation. l The principles of verifying a conflict trail are as follows: If the networking changes, the trail may cause interruption of service flow. For example, the key information for the trail, including deleting a cross-connection or fiber, is verified.

4.

Click Next after searching, you can browse all trails found. If you want to set a trail management flag, right-click it and select the management flag. NOTE

Skip this step if you selected the "Automatically create trails after searching" policy in Step 2.

5.

Click Next to view all discrete services in the network. NOTE

If Step 4 is performed, the U2000 deletes trails that do not have the management flag from the network layer. This does not affect services for the actual NE or the data for an individual NE on the U2000.

99 Creating Single-Station Optical Cross-Connection

Creating Single-Station Optical CrossConnection

Optical cross-connection defines the routes of wavelengths. Through the creation of singlestation optical cross-connection, the routes of inter-board services are configured.

Prerequisite You are an NMS user with "Operator Group" authority or higher. The logic fiber connection inside a single station has been set up on the U2000/Web LCT. The edge port must be configured. When creating an optical cross-connection of a single station, make sure that the optical crossconnection of a board in this single station does not occupy the wavelength that the optical crossconnection of the single station uses.


Background Information When you create an optical cross-connection, the optical power can be adjusted automatically or manually. If you select Auto, the dynamic optical add/drop multiplexer board automatically adjusts the attenuation range of the optical attenuator in the board. If you select Manual, you need to manually adjust the attenuation range of the optical attenuator in the dynamic optical add/drop multiplexer board. The Auto option is available for the several types of optical crossconnection trails. For details, see Feature Description. NOTE

The WSMD4/WSMD2 can be used to replace the WSD9 or the WSM9. OA indicates the optical amplifier boards such as OAU1 and OBU1. The FIU can be added before or after the OA. In drop networking, the demultiplexer boards such as D40, D40V and MR2 can be added between the WSD9 and OTU. In add networking, the multiplexer boards such as M40, M40V and MR2 can be added between the OTU or line board and WSM9.

OSC/ESC Conflict

This section describes workarounds and solutions to the problem associated with frequent switching between OSC and ESC channels during the deployment commissioning phase.

Prerequisites You must be an NM user with "NM operator" authority or higher.


Background Information During the deployment commissioning phase, the commissioning of optical power for an OTU board or a line board is not complete. When this occurs, the ECC link is unstable and the OSC and ESC channels may be frequently switched. The symptoms are as follows: l

As shown on the NMS, the NE is occasionally unreachable. A query of the WDM-side alarms for the corresponding OTU or line boards shows that the power_high or power_low alarm is reported.

l

Switching between different channels on the ECC link frequently occurs.

1.

On the U2000, check the value of Communication Status. Then determine which port fails in ESC communication after a check of the value of Port.

136.1 Overview Overview of the purpose and procedure of cleaning optical fiber connectors, the items that may cause pollution to optical connectors are also described here. Cleaning optical components is to remove dust or other dirt to avoid performance degradation of optical transmission systems. Here describes how to inspect and clean fiber connectors used in fiber optic connections. Figure 136-1 shows the optical fiber connector. Figure 136-1 Optical fiber connector

The following items should be removed because they pollute optical connectors that are extensively adopted in optical transmission systems: l

Dust

l

Oils (frequently from human hands)

l

Film residues (condensed from vapors in the air)

l

Powdery coatings (left after water or other solvents evaporate)

Dust is the most common dirt in optical connectors. Even small dust that can be seen only under a microscope can affect the quality of optical signals, degrade the system performance and cause potential instability in network operation. A one-micrometer dust granule on an optical connector of a single mode fiber can block 1% light and cause 0.05 dB lost. A nine-micrometer dust granule that cannot be seen by human eyes can block an entire fiber core. Therefore, small dirt even that cannot be seen by human eyes should be removed. NOTE

Before you connect any optical component, make sure that you have inspected and cleaned the component.

General Procedure Table 136-1 below describes the general procedure of how to inspect and clean the optical fiber connectors. Issue 02 (2013-12-31)

Precautions

CAUTION Laser is dangerous. The light is not visible to the eyes with or without laser protective glasses. Do not look into optical connectors or ports. Failure to follow this warning can cause damage to the eyes, or even blindness. Use a fiberscope equipped with a safety device or a desktop video fiberscope when you inspect the optical connectors. If one is not available, turn off the lasers and disconnect both ends of the fiber before you inspect the optical connectors

NOTICE Electrostatic discharge (ESD) damages the equipment. Before touching the equipment, board, or integrated circuit (IC) chip, to prevent the ESD on human body from damaging static-sensitive components, you must wear the ESD wrist strap and ensure the other end of the strap is properly grounded. Otherwise, the equipment may be damaged or the service may be interrupted.

Procedure Step 1 Turn off the lasers before the inspection. Disconnect both ends of the fiber to be inspected. Step 2 Test the optical power using a power meter. Ensure that the laser is turned off. Step 3 Use a fiberscope to inspect the fiber to check if there is any dirt or damage. See the examples shown below. l For an image of the intact fiber optic surface through a fiberscope that can be used successfully in the equipment, see Figure 136-7.

Severely damaged fibers must not be used in the system equipment. Otherwise, permanent and severe damage to the assembly can occur. The image on the right shows a fiber that is suspect. If the output power is within an acceptable range, the fiber might not cause any damage to the assembly. If the output power is unstable or falls outside the acceptable range, however, the fiber can cause damage to the assembly and must not be used. Figure 136-8 Damaged or suspect fibers

NOTE

The views shown do not represent the entire surface of the fiber optic. Much of the surface is the metal connector and only the 800-micron core is the actual fiber.

l For details on acceptable and unacceptable fibers, see Figure 136-9, Figure 136-10 and Figure 136-11. Issue 02 (2013-12-31)

136.5 Cleaning Optical Fiber Connectors Using Cartridge Cleaners Clean the fiber optic only in the case that there are flaws on it. The following describes how to clean the fiber optic with a type of CLETOP cassette cleaner.

Prerequisites Before cleaning, inspect the fiber optic surface with a fiberscope or a magnifier to determine the extent to which the fiber optic might be damaged or dirty. Clean the fiber optic only in the case that there are flaws on it. If there are not, do not clean it. That is because the cleaning itself might introduce dust, dirt, or cause potential damage to the fiber optic. The following procedure provides the steps to clean the fiber connectors using cartridge type cleaners. There are several types of cartridge cleaners. The following describes a type of CLETOP cassette cleaner.

Procedure Step 1 Turn off the lasers before the inspection. Disconnect both ends of the fiber to be inspected. Step 2 Use a power meter to measure and ensure that there is no laser light on the optical connector. Step 3 Press down and hold the lever of the cassette cleaner, and the shutter slides back and exposes a new cleaning area. See Figure 136-12. Figure 136-12 Using the CLETOP cassette cleaner

Step 4 Place the fiber tip lightly against the cleaning area so that the end face is flat on the cleaning area Step 5 Drag the fiber tip lightly on one cleaning area in the direction of the arrow once. See Figure 136-13. Do it again on the other cleaning area in the same direction as the first time once. See Figure 136-14.

NOTICE Do not scrub the fiber against fabric or clean over the same cleaning area more than once. Otherwise, the connector can be dirtied or damaged.

Step 6 Release the lever of the cassette cleaner to close the cleaning area. Step 7 Use a fiberscope to inspect the adapter to check if there is any dirt. For details see the examples shown in 136.4 Inspecting Optical Connectors. If the optical adapter is still dirty, repeat the Step 1 to Step 6. Step 8 Connect the fiber connector to the board. Step 9 Turn on the lasers after you connect the fiber to the board. ----End Issue 02 (2013-12-31)

136.6 Cleaning Optical Fiber Connectors Using Lens Tissue Clean the fiber optic only in the case that there are flaws on it. The following procedure provides the steps to clean the fiber connectors using lens tissue.

Prerequisites Before cleaning, inspect the fiber optic surface with a fiberscope or a magnifier to determine the extent to which the fiber optic might be damaged or dirty. Clean the fiber optic only in the case that there are flaws on it. If there are not, do not clean it. That is because the cleaning itself might introduce dust, dirt, or cause potential damage to the fiber optic. The following procedure provides the steps to clean the fiber connectors using lens tissue. Use only the special materials for cleaning the fiber connectors. See the local site practices.

Procedure Step 1 Turn off the lasers before the inspection. Disconnect both ends of the fiber to be inspected. Step 2 Use a power meter to measure and ensure that there is no laser light on the optical connector. Step 3 Place a small amount of cleaning solvent on the lens tissue. Step 4 Clean the fiber tip on the lens tissue. See Figure 136-15 and Figure 136-16.

NOTICE Do not scrub the fiber against fabric or clean over the same cleaning area more than once. Failure to comply can result in connector dirt or damage.

NOTICE Move the fiber connector in the same direction when you wipe the fiber connector on the lens tissue.

Step 5 Repeat Step 4 several times on the areas of the lens tissue that have not been used. Step 6 Use the compressed air to blow off the fiber tip. NOTE

l When you use the compressed air, keep the injector nozzle as close as possible to the fiber connector surface without touching it. l When you use the compressed air, first spray it into the air as the initial spray of compressed air can contain some condensation or propellant. Such condensation leaves behind a filmy deposit. l If the compressed air is not available, a clean roll can be used.

Step 7 Use a fiberscope to inspect the adapter to check if there is any dirt. For details, see the examples shown in 136.4 Inspecting Optical Connectors. If the optical adapter is still dirty, repeat the Step 1 to Step 6. Step 8 Do not touch the fiber connector after you clean it. Connect it to the optical port board at once. If it is not used for the time being, put a protective cap on it. NOTE

A piece of lens tissue can be used for only one time.

Step 9 Turn on the lasers after you connect the fiber to the board. ----End

Step 4 Place a small amount of cleaning solvent on the optical cleaning stick. Issue 02 (2013-12-31)


266



Step 5 Place the optical cleaning stick lightly on the optical adapters so that cleaning solvent is against the fiber tip. Hold the stick straight out from the adapter and turn the stick clockwise one circuit. Make sure that there is direct contact between the stick tip and fiber tip. Step 6 Use the compressed air to blow off the fiber tip. NOTE

l When you use the compressed air, keep the injector nozzle close to the connector surface without touching it. l When you use the compressed air, first spray it into the air as the initial spray of compressed air can contain some condensation or propellant. Such condensation leaves behind a filmy deposit.

Step 7 Use a fiberscope to inspect the adapter to check if there is any dirt. For details, see the examples shown in "136.4 Inspecting Optical Connectors". If the optical adapter is still dirty, repeat the Step 1 to Step 6. Step 8 Connect the fiber to the board, or put a protective cap on the port. Step 9 Turn on the lasers after you connect the fiber to the board. ----End
