Can anyone help with diagnosing the errors I'm getting on one end of a T1? The other end is error free.

Here are the controller stats:

T1 0/1/1 is up.

Applique type is SPA-8XCHT1/E1

Cablelength is long gain36 0db

No alarms detected.

alarm-trigger is not set

Soaking time: 3, Clearance time: 10

AIS State:Clear LOS State:Clear LOF State:Clear

Framing is ESF, Line Code is B8ZS, Clock Source is Line.

Data in current interval (538 seconds elapsed):

0 Line Code Violations, 243 Path Code Violations

0 Slip Secs, 69 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

69 Errored Secs, 0 Bursty Err Secs, 69 Severely Err Secs, 0 Unavail Secs

0 Near-end path failures, 0 Far-end path failures, 63 SEF/AIS Secs

Total Data (last 6 15 minute intervals):

0 Line Code Violations, 2348 Path Code Violations,

0 Slip Secs, 727 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins,

737 Errored Secs, 0 Bursty Err Secs, 727 Severely Err Secs, 0 Unavail Secs

These are typically circuit problem for which you have to complain to telco.

The fact one side doesn't show errors does not mean anything, because circuits are not like a wire where errors must be symmetric.

That' been my experience in the past, but I'm being told by the carrier that they are detecting problems on our equipment. I just wondered if there were any simple changes I could try - such as cable length - that might attest to the errors we're seeing before thowing it back at the carrier.

Not really. Telcos have an habit of blaming cust. before doing anything else.

Paolo is absolutely correct about the Telco. I just got done doing the same thing with a telco. I did all the usual things like replacing the cable checking the config and things like that. They came out and tested and said they did not find anything but guess what all of a sudden the circuit was clear....go figure. Then the best part when they replaced the faulty equipment they took down our ISDN PRI, again blamed our equipment but when they came out to check and "did not do anything again" the phones started working again....go figure.

Telco's got to love them.
