Hello ,
We are using channelized E1 on a PRI card of cisco3600 , for multiple 64K
ckts coming from a MUX which is placed at the TELCO .
1) Is it possible to get a loop on the channelized PRI controller( show
controller e1) by giving a 4 wire physical loop ? I did not get the loop on
the E1 controller of cisco router , by giving a four wire loop or by taking
a loop from TELCO . Loop is ok if tested on BERT meter .
2) All connectivity/media is ok but the TELCO person observes an alarm on
the MUX when the channelized E1 is terminated at the Cisco PRI card on a
3600 router.
3) The o/p of the controller is given below :
show controllers e1 1/0
E1 1/0 is down.
Applique type is Channelized E1 - balanced
Transmitter is sending remote alarm.
Receiver has loss of signal.
alarm-trigger is not set
Framing is NO-CRC4, Line Code is HDB3, Clock Source is Internal.
Data in current interval (29 seconds elapsed):
0 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 29 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 29 Unavail Secs
Data in Interval 1:
1 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 827 Fr Loss Secs, 1 Line Err Secs, 0 Degraded Mins
...................................................
If anyone knows how to resolve this pls help me out.
Thanks & Regards,
Vijendra.
