Description (partial)

Symptom:
If Squelch is disabled , LOS-P condition   on trunk   is handled differently on cbr and gfp mapped GE clients .
Local Fault is  sent from client in case of CBR GE  clients and traffic remains down . In GFP GE clients there is a momentary LocalFault and later traffic is recovered.

Conditions:
Steps to Reproduce
==================
1) Have a back to back WSE set up with 10GE GFP mapping and encryption enabled/disabled
2) Set 10GE squelch mode to disabled
3) Create a FEND client SIGLOSS/Syncloss. GFP-CSF is raised on NEND. For squelch enabled, the port will squelch. In case of squelch disabled, momentary LF is reported by the test set connected to the NEND client port. End to end traffic remains down with the test set/device connected to the NEND WSE client, without any alarm
4) For NEND trunk faults (LOS-P), GFP-CSF is raised as expected but the test set/device doesn't receive any alarm . They just see the traffic going down
5) In case of CBR mapping, for the same scenario, LF is sent out of the client for as long as the fault (ODU-AIS) persists. Hence the FEND will know that there is a problem
