Hello!
Could anyone explain me why does a MN-2CE1B show up as "unbalanced"? (see the output of commands sh contr e1 and sh diag below). Acording to the specs this is balanced card.
Router#sh controllers E1
E1 1/0 is down.
Applique type is Channelized E1 - unbalanced
Transmitter is sending remote alarm.
Receiver has loss of signal.
Framing is CRC4, Line Code is HDB3, Clock Source is Line.
Data in current interval (430 seconds elapsed):
0 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 430 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 430 Unavail Secs
Total Data (last 1 15 minute intervals):
0 Line Code Violations, 0 Path Code Violations,
1 Slip Secs, 900 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins,
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 900 Unavail Secs
