ODU PSU : Power Supply Alarm returned from the ODU. This alarm is active when there is a
ODU Cable : ODU Cable Alarm is generated by the ODU in case of a transmit IF level below
Transmit Power : A transmit Power alarm is generated by the ODU in case of a transmitter
Transmit Frequency : This alarm is generated in case of IF or RF transmit synthesizer faults.
Receive Frequency : This alarm is generated in case of IF or RF receive synthesizer faults.
Receive Level : This alarm is generated when receive signal level is below the receive
Tributary Alarms : a tributary alarm is generated when there is a lack of input signal for a tributary
IDU Alarms
Warning 1+1 : A 1+1 warning is generated when the main or the standby units (ODU or cable
ID Code : When local and remote ID Code do not match, there is an ID Code alarm generated,
IDU : This alarm is active in case of an IDU fault, or in case of problem to recover receive data.
