When i type: show controller e1

on the router, i find the following:

E1 0/1/0 is up.

Applique type is Channelized E1 - balanced

No alarms detected.

alarm-trigger is not set

Version info Firmware: 20070321, FPGA: 13, spm_count = 0

Framing is CRC4, Line Code is HDB3, Clock Source is Line.

CRC Threshold is 320. Reported from firmware is 320.

Data in current interval (588 seconds elapsed):

0 Line Code Violations, 584992 Path Code Violations

0 Slip Secs, 2 Fr Loss Secs, 0 Line Err Secs, 9 Degraded Mins

0 Errored Secs, 0 Bursty Err Secs, 2 Severely Err Secs, 2 Unavail Secs

Total Data (last 24 hours)

2 Line Code Violations, 85962281 Path Code Violations,

73 Slip Secs, 555 Fr Loss Secs, 1 Line Err Secs, 1418 Degraded Mins,

72 Errored Secs, 0 Bursty Err Secs, 555 Severely Err Secs, 773 Unavail Secs

If, 85962281 Path Code Violations make a problem which make the E1 flap and if it can be solved from the router side configuration or must be solved from the telco side

Hello there.

Check out using "cablelength" command. I suppose framing/line code is correct..

I would contact Telco anyway to check other side of this e1.

You have been asking this question again, please do not open duplicates.

You have a faulty circuit, even if telco says otherwise.

It does not annoys me, it is just good forum etiquette not to open thread duplicates.

Remember: forum cannot fix a faulty circuit. Telco can.

ok, i understand what do you mean, but, i am this time asking another different question.

Paolo is correct, this needs to resolved by the telco. I was also having the same issue on one of my E1 circuits and the telco kept saying it was our equipment. Please check the following document for more information and what you can do to show the telco it is on there end.

Hope this helps.

No problem. Good luck with the telco. Our circuit finally got fixed. I was getting errors every few minutes and getting drops a few times a day while they kept telling me it was my equipment. Then all of a sudden all my errors went away and no more issues with the circuit dropping. When I asked what they did they said they did not do anything, aren't telco's great... :-)

remember to rate helpful posts.

Thanks,

Mike
