Analog dial-up to ISDN BRI on a 2620 router

[lee.alexander]

I am trying to set up my 2620 router with a 4 port ISDN NT1 card to allow analog modems to dial-in. Anyone do this now and know any pointers for me?

Its not possible. Once you have the NM-4B-U in the lone NM slot in your 2600s, there is no place

left for the NM-AMs. If you had a 3600 instead, you could have used the 12.0(3)T feature of modem over BRI :

2600 router will not support the analog calls over isdn line at all. 3600 does that with mica as digital modem in the router..So what you are trying to do need 3600..Thx..Tejal
