Procedure 10-2: Discontinue DS1 or E1 service
Overview
Use this procedure to discontinue DS1 or E1 service.
Important!
This procedure assumes that the Alcatel-Lucent 1850 TSS-5 is in service and that a DS1/E1 port is being discontinued.
Before you begin
Prior to performing this procedure:
-
Refer to Before you begin and Required equipment in this chapter.
-
Refer to Electrostatic discharge in Chapter 1, Safety.
-
Obtain the work instructions for this procedure.
-
Verify that the work instructions specify the terminating nodes, pass-through nodes, DS1/E1 port addresses, and cross-connections to be deleted.
Steps
Complete the following steps to discontinue DS1 or E1 service.
1 |
Using the work instructions, determine the DS1/E1 ports to be discontinued. |
2 |
At the terminating nodes, click the Alarm List button from the System View menu to obtain an NE Alarm List and verify that no alarms are present. Clear all system alarms before continuing this procedure. Reference: Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Maintenance and Trouble-Clearing Guide |
3 |
Important! This step may activate the office major, minor, or no alarm. The audible alarm may be suppressed by pressing the ACO/TST 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. |
4 |
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. |
5 |
At the terminating nodes, select Configuration → Update System → Update States to clear the DS1/E1 LOS alarms. Result: The flashing FAULT LEDs go off. |
6 |
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. |
7 |
At the terminating nodes, select View → Equipment to access the required DS1/E1 ports and verify that the Port Monitoring Mode changed to AUTO. |
8 |
Determine the cross-connections for the circuit being discontinued using the work instructions, or at the terminating nodes and pass-through nodes, select View → Cross-Connections to obtain a current list of cross-connections. Record the source addresses (SRC) of the cross-connections to be deleted. |
9 |
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.) |
10 |
If required, at each pass-through node 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.) |
11 |
At the terminating nodes and pass-through nodes, click the Alarm List button to obtain an NE Alarm List and verify that no alarms are present. End of steps |
