I'm trying to configure a 1721 using the AUX port with external USR modem to dial up to a MS-RAS server as a backup. Everything dials fine and it goes through the necessary modm handshake etc.. but my async interface just disconnects/resets for somereason. Not sure if I'm missing something in my config or I have something misconfigured. Any assistance would be appreciated. I have pasted the config below with some debug outputs.

Hi,
It looks like the modem is dropping the connection, see the DSR

00:17:41: TTY5: DSR was dropped

00:17:42: TTY5: dropping DTR, hanging up
00:17:42: TTY5: Set DTR to 0
Moreover I shall request you to paste output from following debugs:
1. debug modem
2. debug ppp authe
Kind Regards,

Hello I just tested changing the async int to autodetect encap ppp and it looks like it's holding up a little bit longer but it then goes back down. I ran the same debugs and the output it a little different. Still cant' figure it out. Do you think my modem might be bad? It's a new modem fresh out of the box.
