TAP-174: Trouble Clearing 365-575-102

2. Log in to the node with the incoming (from OC-48) STS LOP condition
(called the local node.) If a remote login is required and you need additional
help, refer to DLP-524.
3. From the Active Alarms and Status Report, identify and record the Source
Address (AID) associated with the STS LOP condition and note the East or
West line direction of the tributary (sts-1e-# or sts-1w-# where # is the tributary
number [value 1 through 16]).
4. At the CIT, select FAULT-Retrieve-History command and execute to
obtain a Maintenance History Report.
5. Determine from the report (in Step 4) if a repeating pattern is occurring
between the East and West TRMTR circuit packs. For example (Figure 1), a
repeating pattern is occurring between line-1e with TRMTR failure and
TRMTR failure-cleared and line-1w with TRMTR failure and TRMTR
failure-cleared.
If NO, then continue with Step 6.
If YES, then continue with Step 10.
