Whenever I activate my DDR line it connects just fine until I try to send traffic across it. Then it disconnects the line. Config and debug below - any help would be appreciated.

The problem is with the dialer map..In the dialer map you need to configure the ip address and the exact name of the host receiving the call..
In your config the hostname MONTGOMERY belongs to the router dialing out..and hostname JSSB-MAIN belongs to router which is receiving the call.
as per the debug line
3w4d: As2 DDR: Remote name for JSSB-MAIN
3w4d: As2 DDR: Authenticated host JSSB-MAIN with no matching dialer map
So on this MONTGOMERY router the dialer map should look like this
dialer map ip 10.1.4.1 name JSSB-MAIN broadcast 1111111
So once you will change the dialermap, it will work fine.

Does this work differently for an async than an ISDN connection? I've got a very similar config using ISDN as opposed to the ASYNC, and it works perfectly. The BRI in the router config listed below is dialing into a PRI on the same router that MONTGOMERY is attempting to access on a WIC-2AM without any problems.

dialer load-threshold 1 outbound
dialer watch-group 1
dialer-group 1
isdn switch-type basic-ni
isdn spid1 11111110101
isdn spid2 11111110101
ppp authentication chap
ppp chap hostname DUBOISTOWN
ppp chap password xxxx

This worked just fine. I had a second problem as well, and that was the chat script was timing out too soon. I increased the timeout from 30 to 60 seconds and everything worked great. Thanks for the reply.
