E1 Card.

[paulk29]

Hi all,
I have a Cisco 3640 with Mica Modem Module, I want to have users RAS in over ISDN PRI using an E1 Card. Which E1 Card should I choose? Is there a particular Part code or Module I should order?
Thanks
Paul

Paul,
Depending on how many modem ports you need, the part number is :
NM-6DM
NM-12DM
NM-18DM
NM-24DM
NM-30DM

The number before the DM indicates the number of modems on the E1/T1 network module.

A good reference tool to check part numbers and their compatability between routers is the Cisco Configuration Tools website.

Jimmy,
thanks for the reply. I'm not sure I get you though, I have a Mica Modem Module that sits in Slot 2 of my 3640, this module has 12 Modems. For WAN use I want to know which model number the E1 Card is. In Ireland E1 is 2meg so I just want to configure 12 B channels one for each of the modems that will dial in/out for RAS use. I didnt know you could get an E1 Card with built in Modems.
Thanks again and I hope this a bit more clear.

Paul,
Apologies, for the confusion. You'll need a E1 module inconjuction with the modem module (Usually order it as a bundle and get both the modems and E1). There are many variations/combo of E1 modules. The basic E1 card is NM-1CE1B.

All,
just another related query, how would I configure up the E1 so that 512K is used for internet access and the rest is used for the dial in RAS?
Thanks

Hi Paul,

Required module and configuration depends on your E1 signaling type.
