15. Replace the same side TRMTR circuit pack at the local node as indicated by
the Source Address from Step 3 (Figure 2). For example, if Node 2 is reporting
an incoming (from OC-48) STS LOP condition on sts-1w-6, then replace
the 1w transmitter at Node 2 (local node).
Reference: DLP-514
16. Obtain another Active Alarm and Status Report (use
FAULT-Retrieve-Alarms command or F9 key).
17. Does the incoming (from OC-48) STS LOP condition still appear in the
Active Alarm and Status Report?
If NO, then go to Step 34.
If YES, then continue.
18. Replace the same side TRMTR circuit pack (just installed in Step 15) with the
original TRMTR circuit pack because the trouble still exists.
Reference: DLP-514
NOTE:
Assistance is required at the adjacent upstream node to replace a circuit pack in
the high-speed shelf.
19. Notify personnel to replace the appropriate TRMTR circuit pack at the
upstream node (Figure 2). For example, if Node 2 is reporting an incoming
(from OC-48) STS LOP condition on sts-1W-6, then the 1E transmitter at Node
1 may be the cause of the failure condition.

20. After the new TRMTR boots, obtain another Active Alarm and Status Report
(use FAULT-Retrieve-Alarms command or F9 key).
21. Does the incoming (from OC-48) STS LOP condition still appear in the
Active Alarm and Status Report?
If NO, then go to Step 34.
If YES, then continue.
22. Notify personnel to replace the TRMTR circuit pack (just installed in Step 19 at
the upstream node) with the original TRMTR circuit pack because the trouble
still exists.
Reference: DLP-514
23. At the CIT, select FAULT-Switched-Line:Reset command and execute to
retire the OC-48 Forced Switch.
