Upgrade high-speed BLSR connections at node equipped with compatible OC-48 OLIU in Main slot M2

Procedure 12-11.4: Upgrade high-speed BLSR connections at node equipped with compatible OC-48 OLIU in Main slot M2

Important!

This is not a stand-alone procedure. Perform this procedure only as directed by another procedure.

Steps

Important!

Compatible OC-48 OLIU circuit packs include LNW27 (Series 1:6 and later), LNW29 (Series 1:6 and later), LNW32, LNW76 (Series 1:6 and later), LNW82, LNW202, and LNW221–259 (Series 1:6 and later) OC-48 OLIU circuit packs.

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.

When optical fibers are connected during this procedure, Default K-bytes alarms are reported temporarily.

Complete the following steps to upgrade the in-service high-speed BLSR connections at a node equipped with a compatible OC-48 OLIU circuit pack in Main slot M2.

Are you upgrading a Very Large Fabric (VLF) multi-port, multi-rate LNW82 OLIU to a Very Large Fabric (VLF) LNW59 OC-192 OLIU (one port)?

If...

Then...

Yes

Upgrading an LNW82 circuit pack to an LNW59 circuit pack is only allowed if Port 1 of the LNW82 circuit packs is provisioned as OC-48 and and all other OC-n ports are provisioned as STNA.

Continue with Step 2.

Proceed to Step 4.

Determine the port provisioning of the LNW82, port 1 at the starting node using Reports → Equipment Lists → Ports.Click CP main-1 and then click Select. Observe the Port Type and Application of Main-1-1 and the other ports. Click Close.

What is the Port Type and Application of Main-1-1?

If...	Then...
OC48, blsr and all other ports are STNA	Continue with Step 4.
OC48 blsr and one or more of the remaining ports has a Port Type of OC3, OC12, or OC48	You must roll all traffic from the other ports to any OC-3/12/48 ports in the Function slots in the same shelf. Proceed to Procedure 10-10: Bridge and roll cross-connections to roll the traffic. For each port that you rolled traffic from, change Signal Type to STNA. Select Configuration → Equipment from the System View main menu. Expand the LNW82 circuit pack details and highlight the OCN port and click Select. For Signal Type, select STNA from the drop down menu and click Apply. Refer to Signal Type: STNA if you have issues changing the Signal Type. Repeat this procedure, Procedure 12-11.4: Upgrade high-speed BLSR connections at node equipped with compatible OC-48 OLIU in Main slot M2.
OC48, upsr and all other ports are STNA	Proceed to Procedure 12-8: Upgrade OC-48 UPSR to OC-192 UPSR.
OC48, upsr and one or more of the remaining ports has a Port Type of OC3, OC12, or OC48	You must roll all traffic from the other ports to any OC-3/12/48 ports in the Function slots in the same shelf. Proceed to Procedure 10-10: Bridge and roll cross-connections to roll the traffic. For each port that you rolled traffic from, change Signal Type to STNA. Select Configuration → Equipment from the System View main menu. Expand the LNW82 circuit pack details and highlight the OCN port and click Select. For Signal Type, select STNA from the drop down menu and click Apply. Refer to Signal Type: STNA if you have issues changing the Signal Type. Proceed to Procedure 12-8: Upgrade OC-48 UPSR to OC-192 UPSR.
OC3 or OC12 (Application does not matter)	Upgrade of Port 1 to an LNW59 is not supported. End of procedure.

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

Reference:

Procedure 12-11.5: Verify active/standby status of circuit pack to be replaced

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, 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.

For more information about the Ring Upgrade Mode, refer to Ring Upgrade Mode.

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.

Open the lower 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 replacement OC-192 OLIU circuit pack.

Result:

A transmission hit may occur after the 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 replacement OC-192 OLIU circuit pack in Main slot M1 is tested and autoprovisioned.

The system reports an unexpected circuit pack type condition, an inc. OC48 LOS alarm, and a Line Automatic Switch condition for Main slot M1.

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

At both ends of the optical span to be upgraded, perform the following to connect the replacement OC-192 OLIU circuit pack in Main slot M1 and the required OC-192 circuit pack/port at the opposite end of the upgraded OC-192 optical span:

Clean and connect the transmit optical fibers.
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-192 circuit packs.)
Clean and connect the receive fibers.

Result:

The inc. OC48 LOS alarm and Line Automatic Switch condition clear. Transmission is now supported on the upgraded optical span.

Procedure 14-4: Perform connection and verification of optical facility

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

If required, verify the active/standby status of the OC-48 OLIU circuit pack in Main slot M2 and perform manual switches to switch traffic away from an active circuit pack.

NOTICE

Equipment damage hazard

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!

Open the lower 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. Then replace the OC-48 OLIU circuit pack in Main slot M2 with the replacement OC-192 OLIU circuit pack.

Result:

A transmission hit will occur after the OC-48 OLIU circuit pack is removed. The transmission hit is the result of an internal system timing adjustment to accommodate different line rates in the two Main slots.

The replacement OC-192 OLIU circuit pack in Main slot M2 is tested and autoprovisioned.

The unexpected circuit pack type condition for Main slot M2 clears. The system reports an inc. OC192 LOS alarm and a Line Automatic Switch condition for Main slot M2. Alarms may also be reported at other nodes in the ring.
