You need one of the following in a 2600 or 3600 (you can also get them as port adapters for larger routers). The configuration that you have right now is not going to work.

I have a main office, and 4 remote offices. The local telco has created a point to point setup for me using a DACS. Basically, it takes a full T1 from the main office and splits it into four 56k links (each on only one timeslot) which go to the remote offices. There are plans to add more remote offices later. I have installed a 805 with an Adtran 56/64 DSU at the remote sites (set to 56) and a 1721 at the main office, with a T1 DSU WIC in it. My configs are at the end... The problem is, it does not work. When I use a loopback plug on the 1721, or the adtran, I can ping my serial interface properly. When the loopback is removed, and the line installed, I cannot ping my local serial interface, nor anything else. Please help! Thanks!
