I am a "data guy" and don't have access to the csu/dsu. The company in charge of the phone system has configured two 100 dcd cards for a point to point t1 line. The voice portion of the line is working fine. The data side is down, but works while someone make a call across this line. The company that does the phones is telling me that I need to send something to start the connection but I/them don't know what that would be. I have cisco routers connected on both ends with v35 cables. The routers are running hdlc but none of the keepalives go thru unless someone is on a voice channel. Any suggestions on possible config problems on either the ciscos or csu/dsu would be appreciated.
