The first thing you need to do is reset all the counters on the router to determine how bad your errors are. You are receiving (or have received) input errors on the serial 0 interface. Try doing a SHOW CONTROLLERS SERIAL 0 command to look at the layer 1 statistics of the T-1. It will show you the alarms and errors on the T-1 itself. Also re-verify that you have all your DS0's configured correctly. Make sure that if you are supposed to be using a full T-1 bandwidth then you should have 24 DS)'s configured. Make sure that your Coding and Fraing for the T-1 are also configured correctly. Try performing a T-1 loopback onto yourself to verify if the errors are coming from within your building or from the carrier. Verify that the remote end is receiving errors or not. Once you have determined most of this information then you can start to pinpoint your point of failure...Good Luck...Pls rate...
I reset the counters as mentioned above.. A little history on this T-1 line though is needed. At one point in time we had issues and bell south came out and checked it out. I believe the issues are gone now and were reflected in the counters since they have most likely never been reset. Reset the counters now i have the below..
