Vol. VI-B-56
Signal source for this container is not present.
Check for other alarms that may indicate a loss of signal or a weak/degraded
signal, such as LOS, OOF or Signal Degrade/Fail BER.
Check to see if alarms are present on the remote-end mux, which may indicate a
both-way cable-related fault. If one way (far-end Tx, local-end Rx), check/
replace the optical transceiver or complete mux card at each end.
LOP is raised when invalid STS-1 pointers are received for 8 consecutive frames
of 8 consecutive enabled NDFs were detected. It indicates loss of synchonization
and/or excessive jitter.
Loss of Multi-frame (LOM) detected in container x. This is a minor alarm.
The multi-frame indicator is missing or invalid.
Check for other alarms that may indicate receipt of an errored signal, such as
LOS for a weak signal and LOP for loss of sync through excessive jitter.
If all other indicators are OK, replace the DAC 155oM.
Alarm is raised for incorrect H4 value for 8 frames. The correct 4 frame sequence
was not detected for 8 frames.
Remote degrade/defict indication (RDI) in container x. This is a minor alarm.
There is a problem with the transmitted signal in this container.
Check for other higher-level alarms, such as RDI-in.
