T1 CAS Trunk Line/Path Code Violations?

I received a compliant from an attendant of dropped calls when transferring  at a remote site. 

What I though was a PRI line at the site turned out to be a CAS trunk. I've never dealt with these before. 

I noticed a lot of line/path code violations. Could this be the cause of my trouble?

 

Does anyone see anything obvious in the config or have any suggestions to share?

 

Thanks, 

 

Phill

Line code violations are

Line code violations are usually a provider problem or a cabling problem. I would open a case with the provider and they should be able to do some tests on your circuit.

Turns out that it was

Turns out that it was improper line coding. 

Telco was set to B8ZS...my side was set to AMI. Errors went away as soon as this was set correctly. Kind of questioned that from the beginning...AMI is unusual this day and age.
