You should perform local loopbacks at each end (if possible) to check your serial interfaces. You can also look at the output from "debug serial interface" and see what end of the connection seems to be the problem. http://www.cisco.com/warp/public/779/smbiz/service/troubleshooting/ts_ll.htm There are a number of troubleshooting documents on Cisco's site.
