Description
Specification
Status Communication alarm (COMFAIL>set
delay 100 ms in service, 5-10 ms for
fault tracing)
Status % No of sent messages
Status % No of received messages
Time Round trip delay/2 + set asymmetric
delay
Time Actual transmission delay + measured
asymmetric delay (+or -)
Setting / GPS Asymmetric delay (Setting in echo
ms mode or measured with GPS timing)
Value Measured received optical power
Status Differential protection blocked by
communication
Status Incoming message from a non-valid
address
Received address from remote end
Configured remote address
Status Redundant channel 0=inactive 1=active
Status CRC error in incoming message
Status Transmission delay error, > 40 ms
Status Error in echo timing synchronization
Status Error in received message at remote
end
Status Error in GPS synchronization at local or
remote end
Status No carrier is detected in the incoming
message. Group signal - Logical OR for:
• LINK_LOST (no input data stream
at the optical receiver)
• SYNC_LOST (clock
synchronization is lost)
• C37 ERROR (error at the C37.94
fiberoptic receiver: faulty format)
Status No start and stop flags in the incoming
message
Status Incorrect length for the incoming
message
Status Detected error in an incoming message
at the remote end
Status Low signal level in the receive link
Status Analog channel activated (configured)
