can any one explain the cause for the faults code mention below for RBS2204 Ericsson.
PCM SYNCH (NO USABLE PCM REFERENCE)
The synchronisation reference from the PCM network is faulty
(for example too much jitter/wander) or missing. The fault
message is raised if:
– TF has been trying to synchronise towards the PCM reference
for more than 5 minutes.
– TF did not recover before the holdover timeout, that is the
fault message AO TF EC2:1 was active for too long.
Note: Only when TF mode is master or stand-alone.
