Hi,
I am going through the exact same situation as Thomas did. 4331 router with single E1 interface. My telco is Telmex (Mexico) and their E1 R2 circuit handoff was a pair of coaxial cables for which I had to use BNC-to-RJ45 converter. I had very hard time getting the configuration information from the telco which I got after so many requests. The circuit came up after applying the settings and seemed to have stayed up for a while. There were no errors in the line for a while but now I am seeing tones of slip seconds, line code violations, path code violations errors. Telco says they don't see any issues at their end. And sadly I don't see issues at my end either. Then I am trying to figure out where exactly is the issue?
I am attaching the output of sh controller e1
E1 0/1/0 is up.
Applique type is Channelized E1 - unbalanced
No alarms detected.
alarm-trigger is not set
Framing is no-crc4, Line Code is HDB3, Clock Source is Line Primary.
International Bit: 1, National Bits: 11111
Data in current interval (360 seconds elapsed):
0 Line Code Violations, 0 Path Code Violations
10 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
10 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
Total Data (last 1 15 minute intervals):
4 Line Code Violations, 241 Path Code Violations,

381 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 160 Unavail Secs
And here is the controller configuration

There are no network clock sources configured
Active source = UNAVAILABLE
All Network Clock Configuration
---------------------------------
Priority Clock Source State Reason
Current operating mode is Revertive
Current OOR Switchover mode is Switchover
There are no slots disabled from participating in network clocking
Can someone give me any insights based on above outputs and configuration where I should be looking or what configuration change is required in order to resolve this problem.
Thank you so much,
