The NE declares an SSF-L failure against an STM-n line if one of more of the following defects persists for the alarm processing ± 0.5 seconds. Refer to SET-ATTR-ALM:almdel in Alcatel-Lucent 1850 Transport Service Switch (TSS-5) TL1 Command Guide for MSPP.
inc. STMN LOS . Refer to inc. STMN LOS.
inc. STMN LOF . Refer to inc. STMN LOF.
Note: While a typically default alarm delay is 2.5 (±0.5) seconds, the NE default alarm delay is 2 seconds. Upon declaring and the failure, the NE sends an alarm message to the appropriate OS(s). The NE clears an SSF-L failure when all defects that contribute to the alarm are absent for 10 (±0.5) seconds. After clearing the failure, the NE also sends an alarm message to the appropriate OS(s).

|
Description |
server signal fail |
|
Likely Cause |
The SSF-L alarm(s) is declared coincident with a inc. STMN LOS or inc. STMN LOF alarm. An unprotected STM-n line has a coincident LOS or LOF alarms: MJ (SA). A protected STM-n line has a coincident LOS or LOF alarms: MN (NSA). |
|
Visible Indication |
Lighted CR/MJ or MN/ABN LED on SYSCTL faceplate and a flashing FAULT LED on the failed circuit pack. |
|
Action |
In the alarm list, find the associated inc. STMN LOS and/or inc. STMN LOF alarm, and proceed to Procedure 5-36: Clear "inc. OCN/STMN" conditions/alarms. |
