I need to configure a 2921 router with a 1 port and a 2 port T1/E1-PRI EHWIC to replace an old AS5350XM RAS server. Trying to locate documentation for such a config is frustrating to say the least.
I took my best shot at configuring this thing, and it will answer calls, but the console just shows that an incoming ISDN call (with an associated serial interface) was answered, and then after 60 seconds, it shows a disconnect. I had debugs running for ppp authentication and radius authentication but there was no activity at all from those.
The relevant bits of the config follow. What's missing and/or messed up here? The router claims to have 36 "modems" available. Dial up configuration seems to be well on its way to becoming a lost art!
