Install the required replacement OLIU circuit packs and pluggable transmission modules.

Important!

The pluggable transmission modules installed in the original OLIU circuit packs may be moved to the replacement OLIU circuit packs later in this procedure when the optical fibers are moved.

Reference:

Procedure 4-3: Install OLIU circuit packs in Function slots

Using the work instructions, select Configuration → Equipment to access the replacement OLIU circuit packs and provision the required parameters for the circuit packs and each pluggable transmission module/port.

Reference:

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

Using the work instructions, select Configuration → DCC Terminations to access and provision each DCC port on the replacement OLIU circuit packs.

Reference:

Procedure 6-4: Provision DCC terminations

Important!

If the provisioned Timing Mode is Line and the Optical Synchronization Source is an optical port on the OLIU circuit pack that is to be upgraded, the Optical Synchronization Source must be reprovisioned to an optical port on the replacement OLIU circuit pack or to a different optical port not involved in the upgrade.

Select View → Timing/Sync to access the System Timing parameters and observe the provisioned Timing Mode and Optical Synchronization Source. Click Close.

If required, use local operating procedures to determine which optical port to provision as the new Optical Synchronization Source.

Important!

Perform this step only if the Optical Synchronization Source is to be reprovisioned to a different optical port not involved in the upgrade.

If the Optical Synchronization Source is to be reprovisioned to an optical port on the replacement OLIU circuit pack, the Optical Synchronization Source is reprovisioned later in this procedure only after transmission is supported on the replacement OLIU circuit pack.

If required, select Configuration → Timing/Sync to reprovision the Optical Synchronization Source to a different optical port not involved in the upgrade.

Reference:

Procedure 6-5: Network Element synchronization provisioning

Important!

Traffic is moved from the original OLIU circuit pack to the replacement circuit pack one port (unprotected applications) or port pair (protected applications) at a time.

Using local procedures, determine the first port/port pair to be moved to the replacement OLIU circuit pack.

Important!

All cross-connections that are associated with the OLIU circuit packs that are to be upgraded must be identified so that traffic can be moved to the replacement OLIU circuit packs.

Select View → Cross-Connections to access the OLIU circuit pack/port and obtain the current list of cross-connections for the port/port pair being moved. Identify and record all through, add, drop, and UPSR Dual Ring Interworking cross-connections. Click Close to exit.

Important!

A UPSR Dual Ring Interworking cross-connection consists of a 1-way add, a 1-way through, and a 1-way path protected drop cross-connection. To verify that a cross-connection leg is part of a UPSR Dual Ring Interworking cross-connection, click on the cross-connection leg in the list of cross-connections and click View Graphic.

For additional information about UPSR Dual Ring Interworking cross-connections, refer to Procedure 10-11: Establish dual ring interworking (DRI) connections.

Add cross-connections allow traffic to be added to tributaries on the optical port being upgraded.

Drop cross-connections allow traffic to be dropped from tributaries on the optical port being upgraded.

Important!

If required by local procedures, manual protection switches may be performed at the terminating drop nodes and the other drop/continue node to switch Dual Ring Interworking traffic away from the node being upgraded.

If required, use circuit layouts and follow local procedures to identify the terminating nodes and the other drop/continue node for each UPSR Dual Ring Interworking cross-connection identified in Step 7. Select Reports → Path Protection List to verify the active/standby status of the required paths.

If required at each terminating node and the other drop/continue node, select Fault → Protection Switch to access the required paths and perform a Manual switch to switch Dual Ring Interworking traffic away from the node being upgraded.

For each UPSR Dual Ring Interworking cross-connection identified in Step 7, select Configuration → Cross-Connections and use the Cross-Connection Wizard to delete the UPSR Dual Ring Interworking cross-connections. Then use the Cross-Connection Wizard to create the same UPSR Dual Ring Interworking cross-connections on the replacement OLIU circuit packs.

Result:

Alarms may be reported at other nodes in the network.

Reference:

Procedure 10-11: Establish dual ring interworking (DRI) connections

Important!

Do not perform this step for a 1-way through cross-connection associated with a UPSR Dual Ring Interworking cross-connection.

For each through cross-connection identified in Step 7 that is not part of a UPSR Dual Ring Interworking cross-connection, select Configuration → Cross-Connections and use the Cross-Connection Wizard to create the same through cross-connections on the replacement OLIU circuit packs.

Reference:

Procedure 10-5: Make VT1.5 or STS-n cross-connections, single OC-3/OC-12 UPSR configuration

Important!

Do not perform this step for a 1-way add cross-connection associated with a UPSR Dual Ring Interworking cross-connection.

For each add cross-connection identified in Step 7 that is not part of a UPSR Dual Ring Interworking cross-connection, select Configuration → Cross-Connections and use the Cross-Connection Wizard to bridge the add cross-connections to the required optical ports on the replacement OLIU circuit packs just installed.

NOTICE Service-disruption hazard

Removal of wrong fiber connections will result in a service interruption.

Ensure that you remove only the fiber connections for the OLIU circuit pack/port being upgraded.

Result:

The system reports inc. LOS alarms for the optical ports on the OLIU circuit pack.

If the OLIU circuit pack is protected, transmission hits (less than 60 ms) may occur.

If the OLIU circuit pack is unprotected, service is interrupted until the fibers are reconnected and the traffic is rolled to the replacement OLIU circuit pack.

Alarms may be reported at other nodes in the network.

If required, measure the optical receive power of the receive fiber using an optical power meter. Select the appropriate LBO to attenuate the receive signal to the middle of the allowable optical receive power range. (Refer to the Alcatel-Lucent 1665 Data Multiplexer Extend (DMXtend) Applications and Planning Guide, 365-372-324 for the SONET optical specifications of the OLIU circuit packs/pluggable transmission modules.)

Procedure 6-5: Network Element synchronization provisioning

If required, remove the original OLIU circuit packs from the shelf.

Result:

The system reports CP removed or CP failure alarms.

Select Configuration → Update System → Update All.

Result:

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

All alarms clear.

Important!

It is recommended that the network element database be backed up to a remote OS (for example, OMS) after an upgrade. This creates a current backup copy that includes the replacement circuit packs. The remote OS could use this backup copy to restore the network element database in the event of a catastrophic failure. Attempts to restore the network element database using a backup copy created prior to the upgrade may result in circuit pack failures.

Back up the network element database using the Configuration → Software → Remote Backup command.
