Using the work instructions, determine the DS1/E1 port to be discontinued.

At the terminating nodes, click the Alarm List button to obtain an NE Alarm List and verify that no alarms are present. Clear all alarms before continuing this procedure.

Important!

This step may activate the office alarms. The audible alarm may be suppressed by pressing the ACO push-button.

At the cross-connect panel or equivalent connection point at the terminating nodes, remove the DS1/E1 signal associated with the port being discontinued.

Result:

The FAULT LED flashes on the circuit pack with signals removed.

At the terminating nodes, click the Alarm List button to obtain an NE Alarm List and verify that the correct DS1/E1 signal was removed.

At the terminating nodes, select Configuration →Update System → Update States to clear the DS1/E1 LOS alarms.

Result:

The flashing FAULT LEDs go off.

At the terminating nodes, click the Alarm List button to obtain an NE Alarm List and verify that the DS1/E1 LOS alarm is cleared.

At the terminating nodes, select View → Equipment to access the required DS1/E1 ports and verify that the Port Monitoring Mode changed to AUTO.

Determine the cross-connections for the circuit being discontinued using the work instructions, or at the terminating nodes and non-terminating nodes (UPSRs/BLSRs only), select View → Cross-Connections to obtain a current list of cross-connections.

Record the source addresses (SRC) of the cross-connections to be deleted.

At the terminating nodes, select Configuration → Cross-Connections to access the Cross-Connection Wizard and delete the add/drop cross-connections for all DS1/E1 service being removed.

(Refer to the cross-connection source addresses recorded in Step 8.)

Important!

DS1/E1 slots cannot be unequipped without an alarm until all port cross-connections are removed.

If required, at each pass-through node (UPSRs/BLSRs only) select Configuration → Cross-Connections to access the Cross-Connection Wizard and delete the pass-through cross-connections for all DS1/E1 service being removed.

(Refer to the cross-connection source addresses recorded in Step 8.)

Important!

The LNW6/7 28DS1/DS1PM circuit packs have 28 DS1 ports. The LNW8/LNW801 56DS1/E1 circuit pack has 56 DS1/E1 ports.

If all ports on the circuit pack are being discontinued, you may remove the circuit pack, if required.

Have circuit packs been removed?

If circuit packs have been removed, update the internal equipment list. From the System View menu select Configuration → Update System → Update Inventory.

Click OK.

Insert 177D application blanks or LNW98 Detectable Blank circuit packs into the empty slots, then go to Step 16.

If circuit packs have not been removed, provision the Port Monitoring Mode of the DS1/E1 ports to AUTO, NMON, or IS, as required.

From the System View menu select Configuration → Equipment, expand the required circuit pack details, then select the DS1/E1 port.

Under the Fault Management section, select NMON (Not Monitored) or AUTO (Automatic) for the Port Monitoring Mode .

Important!

If the Port Monitoring Mode is NMON, the port is not monitored/alarmed, and the port will not automatically transition to the in service state if a valid signal is detected. If the Port Monitoring Mode is AUTO, the port automatically transitions to the in service state if a valid signal is detected and the port is monitored/alarmed. If the Port Monitoring Mode is provisioned to IS, the port is monitored and alarms are reported.

At the terminating nodes and non-terminating nodes (UPSRs/BLSRs only), click the Alarm List button to obtain an NE Alarm List and verify that no alarms are present.
