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

Important!

This procedure assumes that the far-end node is still equipped with the original OC-12 OLIU circuit packs/pluggable transmission modules.

To verify that the original OC-12 port parameters are provisioned correctly, select View → Equipment and expand the required circuit pack. Click on the original OC-12 port and Select to obtain the port parameters. Click Close.

If required, provision the original OC-12 port pair according to the work instructions using the Configuration → Equipment command.

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

To verify that the original OC-12 port DCC parameters are provisioned correctly, select View → DCC Terminations to obtain the DCC channel status. Click Close.

If required, provision the original OC-12 port DCC parameters according to the office records using the Configuration → DCC Terminations command.

Reference:

Procedure 6-4: Provision DCC terminations

Important!

If the provisioned Timing Mode is Line and the Optical Synchronization Source is either of the upgrade OC-48 ports, the Optical Synchronization Source must be reprovisioned to an original OC-12 port or to a different OC-n port not involved in backing out the upgrade.

At the far-end node, 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 backing out the upgrade.

If the Optical Synchronization Source is to be reprovisioned to an original OC-12 port, the Optical Synchronization Source is reprovisioned later in this procedure only after transmission is supported on the original OC-12 span.

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

Reference:

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

If required at the near-end node, verify the active/standby status of the OC-48 circuit pack in Main slot M1 and perform manual switches to switch traffic away from an active circuit pack.

If the working card (slot 1 card) is to be upgraded and is active, perform an optional manual transmission switch.

1. Select Fault → Protection Switch.

2. Select the required 1+1 Line and click Select.

3. Select the "Manual to Protection" Switch Type and click Apply.

If the protect card (slot 2 card) is to be upgraded and is active, perform an optional manual transmission switch.

1. Select Fault → Protection Switch.

2. Select the required 1+1 Line and click Select.

3. Select the "Manual to Working" Switch Type and click Apply.

Procedure 12-23.4: Verify active/standby status of circuit pack to be replaced

At the near-end node, open the faceplate latch on the OC-48 OLIU circuit pack in Main slot M1. Disconnect the optical fibers from the OC-48 OLIU circuit pack in Main slot M1. Then replace the OC-48 OLIU circuit pack in Main slot M1 with the temporary replacement OC-48 OLIU circuit pack.

Result:

The system reports an unexpected CP type alarm for Main slot M1 . Alarms may also be reported at other nodes.

Reference:

Procedure 4-2: Install OLIU circuit packs in Main slots

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 OC-48 OLIU circuit packs.)

Clean all fiber connectors, and connect the transmit and receive optical fibers to the temporary replacement OC-48 OLIU circuit pack in Main slot M1.

Procedure 14-3: Clean optical fibers, dual LC adapters and LC lightguide buildouts (LBOs)

NOTICE Service-disruption hazard

If the OLIU circuit packs being upgraded carry Ethernet traffic with LCAS enabled, transmission hits (up to 6 seconds) may occur as Ethernet traffic is switched.

The length of the service hits varies based on shelf equipage and TDM/Ethernet service provisioning.

Important!

The UPD/INIT button does not work during this upgrade.

At the near-end node, select Configuration → Update System → Upgrade. Select main-1 (default) as the Directed Slot Choice and click OK.

Result:

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

The temporary replacement OC-48 OLIU circuit pack in Main slot M1 is tested and autoprovisioned.

The system performs an automatic path protection switch, and all traffic is now active on Main slot M1. Transmission hits (less than 60 ms) occur as traffic switches from the circuit pack in Main slot M2 to the circuit pack in Main slot M1.

The unexpected CP type alarm for Main slot M1 clears, and the system reports an unexpected CP type alarm for Main slot M2. Alarms may also be reported at other nodes.

Transmission is now supported on the optical span between Main slot M1 and the OC-48 circuit pack at the far-end node.

Important!

Do not reconnect the optical fibers until instructed to do so. The optical fibers are reconnected after the OC-48 circuit pack is backed out at each end of the optical span.

At the near-end node, open the faceplate latch on the OC-48 OLIU circuit pack in Main slot M2. Disconnect the optical fibers from the OC-48 OLIU circuit pack in Main slot M2. Replace the OC-48 OLIU circuit pack in Main slot M2 with the original OC-12 OLIU circuit pack.

Result:

The original circuit pack in Main slot M2 is tested and autoprovisioned.

The unexpected CP type alarm for Main slot M2 clears. The system reports an unexpected circuit pack type condition and an inc. OC48 LOS alarm for Main slot M2.

Reference:

Procedure 4-2: Install OLIU circuit packs in Main slots

Important!

All cross-connections at the far-end node that are associated with the existing OC-48 1+1 network must be identified so that traffic can be moved to the original OC-12 1+1 network.

At the far-end node, select View → Cross-Connections. Expand the required OC-48 OLIU circuit pack in slot 2 of the Function/Growth group that is currently connected to the OC-48 1+1 network. Click on the required OC-48 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 (Main to Function/Growth) 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-12 port on the OC-12 OLIU circuit pack in slot 2 of the other Function/Growth group.

Reference:

Procedure 10-10: Bridge and roll cross-connections

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.

Disconnect the transmit and receive optical fibers from the upgrade OC-48 port on the OC-48 OLIU circuit pack in slot 2 of the Function/Growth group.

Result:

The system still reports an inc. OC48 LOS alarm for the OC-48 port.

At both ends of the optical span to be backed out, perform the following to connect the original OC-12 port on the OC-12 OLIU circuit pack in slot 2 of the other Function/Growth group and the original OC-12 circuit pack in Main slot M2 at the opposite end of the original OC-12 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 Extend (DMXtend) Applications and Planning Guide, 365-372-324 for the SONET optical specifications of the OC-12 circuit packs.)

3. Clean and connect the receive fibers.

The unexpected circuit pack type condition for Main slot M2 clears, and the system reports an unexpected circuit pack type condition for Main slot M1.

Important!

If the circuit pack is active for timing and/or transmission, opening the latch causes timing and/or transmission switches. Transmission hits (less than 60 ms) will occur for each separate protection switch.

At the near-end node, open the faceplate latch on the temporary replacement OC-48 OLIU circuit pack in Main slot M1. Disconnect the optical fibers from the temporary replacement OC-48 OLIU circuit pack in Main slot M1.
