Important!

For BLSR applications, the port Application parameter must be provisioned 2F BLSR.

Up to 15 BLSR protection groups may be supported by a single network element when the Main slots are equipped with Very Large Fabric LNW59, LNW82, or LNW504 OLIU circuit packs.

From the System View menu at the starting node, select Configuration → Equipment to access the Main 1 and 2 ports and provision the port parameters according to the work instructions.

Result:

The system reports a default K-bytes alarm.

Reference:

Procedure 4-4: Provision OLIU circuit packs/ports for service

Select View → Equipment to access the Main 1 and 2 ports and verify that the ports were provisioned correctly.

At each node in the 2-fiber BLSR (refer to the 2-fiber BLSR worksheet at the end of the procedure), repeat Step 1 and Step 2 to provision and verify the required main OC-n ports.

If an Alcatel-Lucent 1665 DMX is using a Function/Growth slot pair, refer to Procedure 9-9: Establish subtending low-speed UPSR/BLSR to provision and verify the required OC-n ports.

From the system view at the starting node,

1. Select Configuration → Equipment.

2. Select the Ring ID tab and expand the required ring by clicking on the plus sign (+).

3. Click on the required 2F BLSR main-1-{1, 2, 5} protection group and Select.

4. Provision the required protection group parameters according to the work instructions, then click Apply and Close. If no changes were made, click Close and go to the next step.

From the System View menu,

1. Select View → Protection.

2. Select 2F BLSR main-1-{1, 2, 5} and click Select.

3. Click on the Provisionable Parameters tab and verify that the protection group parameters were provisioned correctly. Then click Close.

At each node in the 2-fiber BLSR (refer to the 2-fiber BLSR worksheet at the end of the procedure), repeat Step 4 and Step 5 to provision and verify the main 2-fiber BLSR protection group.

If an Alcatel-Lucent 1665 DMX is using a Function/Growth slot pair, refer to Procedure 9-9: Establish subtending low-speed UPSR/BLSR to provision and verify the required 2-fiber BLSR protection group.

Determine the status of Automatic Ring Discovery.

Important!

The LAPD Role parameter must be provisioned differently at each end of an optical span. For example, if the LAPD Role parameter is provisioned to user-side at one end of an optical span, then the LAPD Role parameter must be provisioned network-side at the other end of the optical span.

From the System View menu at the starting node,

1. Select Configuration → DCC Terminations

2. Select DCC Port dcc-m1-{1, 2, 5}, provision OSI Over DCC as enabled, and the LAPD Role as user-side.

3. Click Apply to make changes.

4. Select DCC Port dcc-m2-{1, 2, 5}, provision OSI Over DCC as enabled, and the LAPD Role as network-side.

5. Click Apply to make changes.

6. Click Close.

Reference:

Procedure 6-4: Provision DCC terminations

From the System View menu, select View → DCC Terminations, verify that the DCC terminations were provisioned correctly, and click Close.

At each node in the 2-fiber BLSR (refer to the 2-fiber BLSR worksheet at the end of the procedure), repeat Step 8 and Step 9 to provision and verify the DCC terminations for the Main ports.

If an Alcatel-Lucent 1665 DMX is using a Function/Growth slot pair, refer to Procedure 9-9: Establish subtending low-speed UPSR/BLSR to provision and verify the required DCC terminations.

Important!

Synchronization Autoreconfiguration is only provisionable if the system timing mode is Line and the Sync Messaging parameter of all ports is enabled. If the Sync Messaging parameter is enabled at any port in the network, it must be enabled at all ports in the network.

If required at the starting node, provision synchronization functions according to work instructions.

Repeat this step at each node in the 2-fiber BLSR (refer to the 2-fiber BLSR worksheet at the end of the procedure).

Reference:

Procedure 6-5: Network Element synchronization provisioning

Important!

If Remote NE Status is to be used, at least one network element must be provisioned as the Alarm Gateway Network Element (AGNE) in the network. If the network element is designated as the Alarm Gateway Network Element (AGNE), the Alarm Gateway parameter must be provisioned Enabled.

From the System View menu at the starting node, select Administration → Set NE, provision the Remote NE Status, Alarm Group, and Alarm Gateway parameters according to the work instructions, and click OK.

Result:

A dialog box appears asking you to confirm executing this command. Click Yes.

Reference:

Procedure 7-9: Set NE defaults — alarm gateway, alarm group, remote NE status, FTP/FTTD, security and history log thresholds

Repeat this step at each node in the 2-fiber BLSR (refer to the 2-fiber BLSR worksheet at the end of the procedure).

Beginning with the starting optical span (refer to the 2-fiber BLSR worksheet at the end of the procedure), connect the fibers between the Main-2 circuit pack at the starting node and the Main-1 circuit pack at the adjacent East node and verify the integrity of the optical span being established.

Procedure 14-7: Perform end-to-end optical line test on Main OLIUs

Repeat Step 13 and Step 14 for each optical span in the 2-fiber BLSR (refer to the 2-fiber BLSR example and worksheet at the end of the procedure).

If connecting to a Function/Growth slot pair at an Alcatel-Lucent 1665 DMX, refer to Procedure 9-9: Establish subtending low-speed UPSR/BLSR to connect and test the optical span.

At the starting node, verify 2-fiber BLSR protection switching:

1. Select Fault → Protection Switch. Select 2F BLSR main-1-{1, 2, 5} and click Select. Choose the East or West direction with switch type Manual to Protection, Ring. Click Apply.

2. Select View → Protection. Select 2F BLSR main-1-{1, 2, 5} and click Select. Observe the Ring Node APS (Automatic Protection Switch) State, East Switch Request State, West Switch Request State, East Channel Status, and West Channel Status parameters. Verify the 2-fiber BLSR protection switch was performed.

3. Select Fault → Protection Switch. Select 2F BLSR main-1-{1, 2, 5} and click Select. Choose the required direction with switch type Clear. Click Apply.

Repeat this step at each node in the 2-fiber BLSR (refer to the 2-fiber BLSR worksheet at the end of the procedure) to verify protection switching.

At each node in the 2-fiber BLSR, click the Alarm List button and verify that no alarms are present. If required, clear any alarms that are present.

The 2-fiber BLSR is now ready for initial service to be established.

Important!

Establishing service requires that the proper slots in each terminating node be properly equipped with the correct circuit pack(s) for the type of service being established. It also requires numerous cross-connections in each of the nodes representing the path of the required service. Additionally, transmission tests should be performed to verify the continuity and quality of the established circuit.
