8125 Loss of synchronization signal(s)

Severity:	Object affected:	Object state:	Module/Unit:
Critical	TRE	Enabled	FIxx
Fault reason:	Instruction:
Field not  used.	All defined synchronisation sources in the synchronisation priority list are invalid or the list is empty. Node is running on its internal clock. 1. Check that synchronisation priority list has Rx clock entries for used interfaces. 2. In case FIFA PIU is used, check that the microwave link is commissioned and operational. Refer to FIFA product documentation for further instructions. 3. If any of the alarms 8050, 8066, 8081, 8099, 8056, 8073, 8277,8278, or 8282 are active, follow the instructions on them.. 4. Check that interface cables are correctly mated to FIxx. Check also condition of the connectors. 5. With FIQA or FIYA and using adaptive clock recovery at a PW as synch source, check if packet switched network is of sufficient quality. Refer to documentation about synchronization of BTS with FIQA, FIYA. 6. Replace FIxx.
