My first thought would be your T1 is down. =) Curious wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: Serial Interface Down [7:61220]
You are not getting any Data Carrier Detect (DCD=Down) to the interface. If it uses an external csu/dsu try a loopback from the csu back toward your router- if everything goes up then it is a most likley problem with the carrier or cable from demarc to your equipment. I assume this was up and running before, but if not try using a T1 crossover from the demarc into your csu/dsu (got burned on that before)to see if that gets it going.
