Procedure 12-19: Upgrade non-VLF OC-48 UPSR to VLF OC-192 UPSR
Overview
Important!
The UPSR must be equipped with Alcatel-Lucent 1665 DMX nodes only. This upgrade procedure does not support upgrading UPSRs equipped with nodes other than Alcatel-Lucent 1665 DMX.
Use this procedure to upgrade an in-service non Very Large Fabric (VLF) OC-48 UPSR to a VLF OC-192 UPSR. To upgrade an in-service non-VLF OC-48 UPSR to a non-VLF OC-192 UPSR, refer to Procedure 12-8: Upgrade OC-48 UPSR to OC-192 UPSR.
This procedure supports upgrading UPSR nodes equipped with non-VLF LNW27, LNW29, LNW32, LNW56, LNW57, LNW58, LNW76, LNW202, and/or LNW221–259 OC-48 OLIU circuit packs to VLF LNW59 and LNW504 OC-192 OLIU circuit packs.
Any UPSR nodes equipped with LNW26B, LNW28, LNW77, or LNW121B–159B OC-48 OLIU circuit pack must be upgraded to LNW27, LNW29, LNW32, LNW76, LNW202, and/or LNW221–259 OC-48 OLIU circuit pack before performing this procedure. Refer to Procedure 12-1: Upgrade cross-connect capacity/port density upgrade of high-speed OLIU circuit packs at a node.
The non-VLF OC-48 OLIU circuit packs in the Main slots are upgraded at each node. This procedure assumes that in the UPSR, the circuit pack in Main slot M1 is always connected to the circuit pack in Main slot M2 of the adjacent node. (Refer to the UPSR example at the end of the procedure.)
Important!
The Very Large Fabric circuit packs are only compatible with the Alcatel-Lucent 1665 DMX High Capacity Shelf (DMX-HC-20A, DMX-HC-30A, or DMX-HC-30A-CE Shelf Type). The Standard Alcatel-Lucent 1665 DMX Shelf does not support upgrades to Very Large Fabric circuit packs.
To determine the shelf type, select View → Equipment, highlight Shelf, and click Select to obtain the shelf details.
Ring Upgrade Mode
During the upgrade, each node connected to the UPSR using the Main slots must be provisioned in the Ring Upgrade Mode. The Ring Upgrade Mode allows cross-connections and provisioning data to be mapped to the replacement circuit pack and prohibits the following operations:
The node remains in the Ring Upgrade Mode until it is manually provisioned back to the Normal mode. While in the Ring Upgrade Mode, the upgrade may be temporarily suspended or backed out. To prevent errors in the upgraded ring, keep all nodes in Ring Upgrade Mode until all nodes have been upgraded.
The Ring Upgrade Mode is an abnormal condition. Therefore, the ABN LED is lighted on the SYSCTL circuit pack faceplate and the WaveStar® CIT Alarm List shows the Ring Upgrade Mode as Not Alarmed.
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. For example, do not replace a circuit pack that has long reach optics with a circuit pack that has intermediate reach optics.
The additional ports on the upgrade circuit pack cannot be used until after the upgrade is completed.
Reported alarm severity levels
The alarm severity levels are reported using the Alarm List and the SYSCTL circuit pack faceplate LED indicators (CR, MJ, MN, or ABN).
Alarm List
The Alarm List is obtained by clicking the Alarm List button. The Alarm List reports detailed information about the current alarms on the local network element. This includes the assigned ASAP alarm severity levels.
For more information about provisioning and assigning ASAPs, refer to Chapter 6, System configuration procedures.
SYSCTL circuit pack faceplate LEDs
The SYSCTL circuit pack faceplate LEDs report the highest active alarm severity level at the local network element or within the alarm group based on the provisioned value of the Remote NE Status parameter.
|
If the Remote NE Status parameter is... |
Then... |
|---|---|
|
Enabled, |
the SYSCTL circuit pack faceplate LEDs at the local network element display the highest active alarm severity level (if any) within the Alarm Group and the FE LED is lighted. |
|
Disabled, |
the SYSCTL circuit pack faceplate LEDs at the local network element display the highest active alarm severity level (if any) at the local network element only. |
|
Enable Far End, |
the SYSCTL circuit pack faceplate FE LED is lighted to indicate an alarm within the alarm group. However, the SYSCTL circuit pack faceplate LEDs at the local network element display the highest active alarm severity level (if any) at the local network element only. |
For more information about provisioning the Remote NE Status feature, refer to Procedure 7-9: Set NE defaults — alarm gateway, alarm group, remote NE status, FTP/FTTD, security and history log thresholds.

Required equipment
The following equipment is required to perform this procedure:
- The following lightguide buildouts (LBOs) should be available:
-
As optical spans are upgraded around the UPSR, ensure that technicians are available at each end of an optical span as it is upgraded.
-
If Main slot M1 at the first node to be upgraded is equipped with an LNW27 (pre Series 1:6), LNW29 (pre Series 1:6), LNW76 (pre Series 1:6), and/or LNW221–259 (pre Series 1:6) OC-48 OLIU circuit pack, one Series 1:6 or later version of the same OC-48 OLIU circuit pack type is temporarily required. For example if the first node to be upgraded is equipped with pre Series 1:6 LNW27 OC-48 OLIU circuit packs, then 1 Series 1:6 or later LNW27 OC-48 OLIU circuit pack is temporarily required.
-
One temporary replacement non-VLF LNW56 OC-192 OLIU circuit pack is required for Main slot M2 at the first node to be upgraded. The temporary replacement non-VLF LNW56 OC-192 OLIU circuit pack is intended for use only as the temporary transition circuit pack during ring upgrades.
A non-VLF LNW57, LNW58, LNW502, or LNW555 OC-192 OLIU circuit pack may also be used as the temporary replacement non-VLF OC-192 OLIU circuit pack. However, the temporary replacement circuit pack must have compatible optics. For example, do not replace a circuit pack that has long reach optics with a circuit pack that has intermediate reach optics. Refer to the Alcatel-Lucent 1665 Data Multiplexer (DMX) Applications and Planning Guide, 365-372-300 for the SONET optical specifications of the OC-192 OLIU circuit packs.
-
Two replacement VLF LNW59 OC-192 OLIU circuit packs for each node.
The replacement circuit packs must have compatible optics. For example, do not replace a circuit pack that has long reach optics with a circuit pack that has intermediate reach optics. Refer to the Alcatel-Lucent 1665 Data Multiplexer (DMX) Applications and Planning Guide, 365-372-300 for the SONET optical specifications of the OC-192 OLIU circuit packs.
Important!
Release 7.1.1 or later software is required to support upgrades to VLF LNW59 OC-192 OLIU circuit packs.
Release 9.0 or later software is required to support upgrades to VLF LNW504 OC-192 OLIU circuit packs.
Important!
All nodes in the existing network must have the same software release before upgrading the network.
 |
NOTICE Equipment damage hazard |
Rocking circuit packs back and forth when removing or installing them can damage circuit pack and/or shelf connectors.
Do not rock circuit packs back and forth when removing or installing them. Carefully slide circuit packs into or out of the shelf slot.
 |
NOTICE Service-disruption hazard |
Removing or installing circuit packs during a System Reset can cause system errors.
Do not remove or install a circuit pack during a System Reset. If a System Reset occurs, wait until the System Reset is complete, then remove or install the circuit pack.
| |
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.
-
Review the applicable office records for each fiber span in the UPSR and the Alcatel-Lucent 1665 Data Multiplexer (DMX) Applications and Planning Guide, 365-372-300 for detailed SONET optical specifications of the OC-192 OLIU circuit packs. Ensure that the OC-192 OLIU circuit packs are compatible with each fiber span in the UPSR. Attenuation and Dispersion may be limiting factors at longer span lengths.
-
Review the applicable Alcatel-Lucent 1665 Data Multiplexer (DMX) Software Release Description for any detailed procedures or cautions that may apply to this upgrade 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.

12 |
Important! If Main slot M1 of the starting node is equipped with a pre series 1:6 LNW27, LNW29, LNW76, or LNW221–259 OC-48 OLIU circuit pack, the circuit pack must be replaced with a Series 1:6 or later version of the same OC-48 OLIU circuit pack type. The Series 1:6 or later OC-48 OLIU circuit pack maintains traffic while Main slot M2 and the other nodes in the ring are upgraded. As a final step, the Series 1:6 or later OC-48 OLIU circuit pack is upgraded. If required, replace the pre series 1:6 LNW27, LNW29, LNW76, or LNW221–259 OC-48 OLIU circuit pack in Main slot M1 of the starting node with a Series 1:6 or later version of the same OC-48 OLIU circuit pack type. Reference: | ||||||
13 |
If required, verify the active/standby status of the non-VLF OC-48 OLIU circuit pack in Main slot M2 and perform manual switches to switch traffic away from an active circuit pack. Reference: Procedure 12-19.2: Verify active/standby status of circuit pack to be replaced | ||||||
14 |
Important! The Ring Upgrade Mode is required for cross-connections and provisioning data to be mapped to the replacement circuit pack. At the WaveStar® CIT System View at the starting node, select Configuration → Ring Upgrade Mode. Result: A dialog box appears asking you to confirm changing the NE Mode to Ring Upgrade Mode. Click Yes. The ABN LED is lighted on the SYSCTL circuit pack faceplate and the WaveStar® CIT Alarm List shows the Ring Upgrade Mode as Not Alarmed.

15 |
If an OC-192 OLIU circuit pack is connected to an OC-48 OLIU circuit pack equipment damage may occur. Do not reconnect the optical fibers until instructed to do so. The optical fibers are reconnected after the OC-48 OLIU circuit pack is upgraded at each end of the optical span. Important! The non-VLF OC-48 OLIU circuit pack in Main slot M2 must be replaced with a temporary replacement non-VLF OC-192 OLIU circuit pack. (Refer to Required equipment for a list of acceptable temporary replacement non-VLF OC-192 OLIU circuit packs.) The temporary replacement non-VLF OC-192 OLIU circuit pack maintains traffic while Main slot M1 and the other nodes in the ring are upgraded. As a final step, this temporary replacement non-VLF OC-192 OLIU circuit pack is upgraded 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. Open the lower faceplate latch on the non-VLF OC-48 OLIU circuit pack in Main slot M2. Disconnect the optical fibers from the non-VLF OC-48 OLIU circuit pack in Main slot M2. Then replace the non-VLF OC-48 OLIU circuit pack in Main slot M2 with the temporary replacement non-VLF OC-192 OLIU circuit pack. Result: A transmission hit will occur after the temporary replacement non-VLF OC-192 OLIU circuit pack is inserted. The transmission hit is a result of an internal system timing adjustment to accommodate different line rates in the two Main slots. The temporary replacement non-VLF OC-192 OLIU circuit pack in Main slot M2 is tested and autoprovisioned. The system reports an unexpected circuit pack type condition and an OC48 LOS alarm for Main slot M2. Alarms may also be reported at other nodes in the ring. If the provisioned system timing mode is External, the system may also report an inc. DS1 sync. ref. OOL alarm. Reference: Procedure 4-2: Install OLIU circuit packs in Main slots This completes the first phase of the UPSR upgrade at the starting node.

Reference: Alcatel-Lucent 1665 Data Multiplexer (DMX) Alarm Messages and Trouble Clearing Guide, 365-372-302 | ||||||
28 |
Important! The network must be alarm free with normal transmission before manually provisioning the nodes back to the Normal mode. After a node is manually provisioned back to the Normal mode, the node cannot be returned to the pre-upgrade state using the backout procedure. At each node in the UPSR, 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. | ||||||
29 |
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. At each node in the UPSR, back up the network element database using the Configuration → Software → Remote Backup command. Reference: End of steps |
