Procedure 12-12: Upgrade cross-connect capacity/port density of high-speed OLIU circuit packs at a node
Overview
Use this procedure to upgrade in-service, the cross connect capacity of the following high-speed OLIU circuit packs at a node in a 1+1/UPSR network:
-
small fabric LNW40, LNW302, or LNW601 OC-3 OLIUs to Very Large Fabric (VLF) multiport, multirate LNW84 OC3/OC12/OC48 OLIUs
-
small fabric LNW38, LNW51, LNW380, or LNW382 OC-12 OLIUs to Very Large Fabric (VLF) multiport, multirate LNW84 OC3/OC12/OC48 OLIUs
-
large fabric LNW41 OC-48 OLIUs to Very Large Fabric (VLF) multiport, multirate LNW84 OC3/OC12/OC48 OLIUs
This procedure may be performed with or without the following circuit packs equipped in the Function A/B slots.
If the Function A/B slots are equipped, the traffic on the original LNW111/LNW112/LNW39/LNW391 circuit packs is migrated to the upgrade LNW84 circuit packs.
Important!
To upgrade the OC-n bandwidth capacity of UPSR networks, refer to the following:
The small fabric LNW40/LNW140/LNW302/LNW601 OC-3 OLIU circuit packs can cross-connect VT1.5 signals in up to 6 STS-1 signals.
The small fabric LNW38/LNW51/LNW380/LNW382 OC-12 OLIU circuit packs can cross-connect VT1.5 signals in up to 12 STS-1 signals.
The large fabric LNW41 OLIU circuit packs can cross-connect VT1.5 signals in up to 48 STS-1 signals.
The VLF multiport, multirate LNW84 OC3/OC12/OC48 OLIU circuit packs can cross-connect VT1.5 signals in up to 192 STS-1 signals.
Important!
The LNW84 OC3/OC12/OC48 OLIU circuit packs are only compatible with the Alcatel-Lucent 1665 DMXtend Shelf with removable center dividers (DMXTEND-RCD-CE Shelf Type). The LNW84 OC3/OC12/OC48 OLIU circuit packs are full-length circuit packs installed in the Main and Function A/B slots.
To determine the shelf type, select View → Equipment, highlight Shelf, and click Select to obtain the shelf details.
Important!
This in-service upgrade is intended to be used with only circuit packs carrying service protected traffic.
Upgrades to multiport circuit packs
When upgrading to a circuit pack with more ports, the cross-connections on the original port are mapped to the same port number on the upgrade circuit pack. The upgrade circuit pack must also be configured with compatible pluggable transmission modules that match the port signal rates on the original circuit pack.
The additional ports on the upgrade circuit pack cannot be used until after the upgrade is completed. After the upgrade is completed, the remaining ports may be configured for any of the available port signal rates allowed for the circuit pack.
Privilege level
You must log in as a Privileged user to complete this procedure.
Required equipment

NOTICE Service-disruption hazard |
Transmission hits (up to 3 seconds) will occur as traffic on LNW20 TMUX circuit packs is switched.
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.
Before you begin
Prior to performing this procedure:
-
Refer to Laser safety and Electrostatic discharge information in Chapter 1, Safety.
-
Obtain the work instructions for this procedure, and verify that the affected circuit pack/protection group AIDs are specified.
-
If required, verify that the LNW111/LNW112/LNW39/LNW391 circuit packs to be upgraded are protected. If only one Function A/B slot is equipped, install the companion circuit pack. Refer to Procedure 4-6: Install DS1/DS3/16/3 circuit packs, Procedure 4-9: Install DS1/E1 circuit packs, or Procedure 4-7: Install DS3/EC1 circuit packs.
-
Review the applicable office records and verify that each fiber span is capable of supporting the replacement circuit pack/pluggable transmission module. Refer to Alcatel-Lucent 1665 Data Multiplexer Extend (DMXtend) Applications and Planning Guide, 365-372-324 for the SONET optical specifications of the replacement circuit packs/pluggable transmission modules.
-
Review the applicable Alcatel-Lucent 1665 Data Multiplexer Extend (DMXtend) Software Release Description for any detailed procedures or cautions that may apply to this upgrade procedure.
-
If the provisioned Timing Source is external, verify that both timing references (REF-1 and REF-2) are in-service (IS) before beginning this procedure.
-
Determine the local operating procedures for removing a circuit pack. Local operating procedures for removing a circuit pack may vary. One method is to disconnect the optical fibers and remove the circuit pack. Another method is to verify the circuit pack active/standby status, perform manual switches if the circuit pack is active, and then disconnect the optical fibers and remove the circuit pack.
Steps
Important!
When optical fibers are disconnected during this procedure, inc. LOS, section DCC channel failed, and neighbor SYSCTL CP unavailable alarms are reported. The holdover mode active condition may also be reported depending on the provisioned system timing mode.
Complete the following steps to upgrade in-service, the cross connect capacity of the high-speed OLIU circuit packs at a node in a 1+1/UPSR network.
1 |
Log in to the node where the high-speed OLIU circuit packs are to be replaced. Reference: Procedure 14-2: Connect Personal Computer (PC) and establish WaveStar® CIT session | ||
2 |
Using the WaveStar® CIT verify the status of the node to be upgraded. Reference: Procedure 12-12.1: Verify status of node to be upgraded | ||
3 |
If required, verify the active/standby status of the circuit packs in the M1 and A1/B1 slots, and perform manual switches to switch traffic away from an active circuit pack. Reference: Procedure 12-12.2: Verify active/standby status of circuit pack to be replaced | ||
4 |
Important! The OLIU circuit pack in Main slot M1 must be replaced first. Open the faceplate latch on the OLIU circuit pack in Main slot M1. (If the circuit pack is active for timing and/or transmission, opening the latch causes timing and/or transmission switches.) Disconnect the optical fibers and remove the OLIU circuit pack from Main slot M1. Result: Transmission hits (less than 60 ms) may occur if traffic exists on the circuit pack in Main slot M1. If through traffic exists (UPSRs only), transmission hits (less than 60 ms) may occur at the nodes where the traffic is added/dropped. The system reports a CP removed alarm. Alarms may also be reported at other nodes in the network. | ||
5 |
If required, open the faceplate latch on the LNW111/LNW112/LNW39/LNW391 circuit pack in slot A1/B1. (If the circuit pack is active for transmission, opening the latch causes transmission switches.) Remove the LNW111/LNW112/LNW39/LNW391 circuit pack from slot A1/B1. Result: The system reports a CP removed alarm. Alarms may also be reported at other nodes in the network. | ||
6 |
Remove the center divider between the M1 and A1/B1 sections of the slot and install the replacement OLIU circuit pack/pluggable transmission module. Result: If a circuit pack firmware update is required, the system reports the Waiting for Download and Install Program IP conditions when the replacement OLIU circuit pack is installed. After the circuit pack firmware update is complete, the system reports an unexpected CP type alarm for Main slot M1. If an LNW111/LNW112/LNW39/LNW391 circuit pack is simultaneously upgraded, the system also reports an unexpected CP type alarm for slot A1/B1. If a circuit pack firmware update is not required, the system reports an unexpected CP type alarm for Main slot M1 and slot A1/B1 (simultaneous LNW111/LNW112/LNW39/LNW391 circuit pack upgrades only) when the replacement OLIU circuit pack is installed. If upgrading to VLF OLIU circuit packs, the system reports a CP removed or CP failure alarm for approximately 4 minutes before reporting the unexpected CP type alarm. Reference: Procedure 4-2: Install OLIU circuit packs in Main slots Refer to the Alcatel-Lucent 1665 Data Multiplexer Extend (DMXtend) Installation Manual, 365-372-327, as required, when removing the center divider between the Main and Function A/B sections of the slots. | ||
7 |
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.) | ||
8 |
Clean all fiber connectors. Connect the pluggable transmission module, LBO, and transmit/receive optical fibers to the replacement OLIU circuit pack in Main slot M1. Reference: | ||
9 |
Transmission hits (up to 3 seconds) will occur as traffic on LNW20 TMUX circuit packs is switched. 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 System View 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 replacement OLIU circuit pack/pluggable transmission module in Main slot M1 is tested and autoprovisioned. The system performs automatic protection switches. Transmission hits (less than 60 ms) occur as traffic is automatically switched from the OLIU circuit pack in Main slot M2 to the replacement OLIU circuit pack/pluggable transmission module in Main slot M1. All traffic is now active on the replacement OLIU circuit pack/pluggable transmission module 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. If an LNW111/LNW112/LNW39/LNW391 circuit pack is simultaneously upgraded the unexpected CP type alarm for slot A1/B1 clears, and the system reports an unexpected CP type alarm for slot A2/B2. Alarms may also be reported at other nodes in the network. | ||
10 |
Open the faceplate latch on the OLIU circuit pack in Main slot M2. Disconnect the optical fibers and remove the OLIU circuit pack from Main slot M2. Result: The unexpected CP type alarm for Main slot M2 clears, and the system reports a CP removed alarm for Main slot M2. | ||
11 |
If required, open the faceplate latch on the LNW111/LNW112/LNW39/LNW391 circuit pack in slot A2/B2. (If the circuit pack is active for transmission, opening the latch causes transmission switches.) Remove the LNW111/LNW112/LNW39/LNW391 circuit pack from slot A2/B2. Result: The unexpected CP type alarm for slot A2/B2 clears, and the system reports a CP removed alarm for slot A2/B2. Alarms may also be reported at other nodes in the network. | ||
12 |
Remove the center divider between the M2 and A2/B2 sections of the slot and install the replacement OLIU circuit pack/pluggable transmission module. Result: The replacement OLIU circuit pack/pluggable transmission module in Main slot M2 is tested and autoprovisioned. If a circuit pack firmware update is required, the system reports the Waiting for Download and Install Program IP conditions when the replacement OLIU circuit pack is installed. After the circuit pack firmware update is complete, the cp removed alarm for Main slot M2 clears, and the system reports an inc. LOS alarm for Main slot M2. If an LNW111/LNW112/LNW39/LNW391 circuit pack is simultaneously upgraded, the cp removed alarm for slot A2/B2 clears. If a circuit pack firmware update is not required, the cp removed alarm for Main slot M2 and slot A2/B2 (simultaneous LNW111/LNW112/LNW39/LNW391 circuit pack upgrades only) clears, and the system reports an inc. LOS alarm for Main slot M2. Reference: Procedure 4-2: Install OLIU circuit packs in Main slots Refer to the Alcatel-Lucent 1665 Data Multiplexer Extend (DMXtend) Installation Manual, 365-372-327, as required, when removing the center divider between the Main and Function A/B sections of the slot. | ||
13 |
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.) | ||
14 |
Clean all fiber connectors. Connect the pluggable transmission module, LBO, and transmit/receive optical fibers to the replacement OLIU circuit pack in Main slot M2. Result: All alarms clear and service is restored. This applies to the local node and the adjacent node connected to the circuit pack in Main slot M2. Reference: | ||
15 |
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. Reference: | ||
