Service-disruption hazard

From office records and work instructions, determine the network configuration and current status of the upgrade.

Important!

At nodes connected to the 1+1 network, the system reports the ring upgrade mode standing condition (not alarmed) in the NE Alarm List until the node is manually provisioned back to the Normal mode.

At nodes connected to the 1+1 network, click the Alarm List button in the top right corner of the System View to view the NE Alarm List and verify that no alarms or standing conditions are present (except ring upgrade mode and ABN condition).

Refer to the appropriate trouble-clearing procedures to clear all existing alarms and standing conditions (except ring upgrade mode and ABN condition) before continuing with this procedure.

Important!

If the provisioned Timing Mode is Line and the Optical Synchronization Source is either of the upgrade OC-12 ports, the Optical Synchronization Source must be reprovisioned to an original OC-3 port or to a different OC-n port not involved in backing out 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 OC-n line 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 OC-n port not involved in the upgrade.

If the Optical Synchronization Source is to be reprovisioned to an original OC-3 port, the Optical Synchronization Source is reprovisioned later in this procedure only after transmission is supported on the original OC-3 span.

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

Identify and log in to the near-end node connected to the 1+1 network using a port pair in the Function/Growth slots and repeat Step 7 through Step 10.

Reference:

Procedure 14-2: Connect Personal Computer (PC) and establish WaveStar^® CIT session

Important!

All cross-connections at the far-end node that are associated with the existing OC-12 1+1 network must be identified so that traffic can be moved to the original OC-3 1+1 network.

At the far-end node, select View → Cross-Connections. Expand the required OC-12 OLIU circuit pack in slot 2 of the Function/Growth group that is currently connected to the OC-12 1+1 network. Click on the required OC-12 port and Select to obtain the current list of cross-connections. Identify and record all add and drop cross-connections. Click Close to exit.

For each add cross-connection identified at the far-end node, select Configuration → Cross-Connections and use the Cross-Connection Wizard to bridge the add cross-connections to the original OC-3 port on the OC-3 OLIU circuit pack in slot 2 of the other Function/Growth group.

At the near-end node, repeat Step 12 and Step 13.

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 optical span being upgraded.

Important!

Do not reconnect the optical fibers until instructed to do so. The optical fibers are reconnected after the upgrade OC-12 circuit pack is backed out at each end of the optical span.

At the far-end node, disconnect the transmit and receive optical fibers from the required OC-12 port on the upgrade OC-12 OLIU circuit pack in slot 2 of the Function/Growth group.

Result:

The system reports inc. OC12 LOS alarms for the upgrade OC-12 ports. Alarms may also be reported at other nodes.

At the near-end node, repeat Step 15.

At both ends of the optical span to be backed out, perform the following to connect the original OC-3 port on the OC-3 OLIU circuit pack in slot 2 of the other Function/Growth group and the original OC-3 port on the OC-3 OLIU circuit pack in slot 2 of the other Function/Growth group at the opposite end of the original OC-3 optical span:

1. Clean and connect the transmit optical fibers.

2. Measure the optical receive power of the receive fibers 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 (DMX) Applications and Planning Guide, 365-372-300 for the SONET optical specifications of the OC-3 circuit packs.)

Important!

This completes the backout procedure, except for taking the nodes connected to the 1+1 network out of the Ring Upgrade Mode. The decision to take these nodes out of the Ring Upgrade Mode or leave them depends on the reason the back out was necessary, and what is required before again starting the upgrade. In the Ring Upgrade Mode, cross-connections cannot be created or removed.

If required at each node connected to the 1+1 network, select Configuration → Normal Mode.

Result:

A dialog box appears asking you to confirm changing the NE Mode to Normal mode. Click Yes.

The ABN LED is turned off on the SYSCTL circuit pack faceplate and the Ring Upgrade Mode will be removed from the WaveStar^® CIT alarm list.
