When I installed an NM-1T3-E3 module in a 3845 Router and did a sho ip interface brief or sho controllers, the module does't appear to be installed; however, upon booting up the router the following information shows:
345 0X000F6400 Clear/Fractional 1 port T3/E3
1 Subrate T3/E3 port
Can someone tell me what I need to do to configure this module? This will be a P2P DS3 connection to headquarters.
Thanks in advance,

Your configuration might look something like this:
card type t3 1
!
controller T3 1/0
clock source line
cablelength 10
! and any other controller parameters that you might need
!
interface Serial1/0
description whatever description you want
mtu 1476
bandwidth 44210
ip address 123.123.123.121 255.255.255.252
encapsulation ppp
keepalive 8
dsu bandwidth 44210
scramble
serial restart-delay 0
!
this is based on the configuration of a working router. Adjust whatever you need to fit your situation.

What you need is a command to tell the router what kind of card (T3 or E3) it is dealing with. Use the command:
card type
and then you should see the serial interface in your config.

Great! Thanks Rick. Now that I got the card recognized by the router, how do I configure the interface for a P2P connection?
In previous routers, I would use the S0 or S1 interface and configure the serial interface for a P2P connection but how do I do it with this T3 card on this newer router?
Thanks in advance,

Just bought a couple of these cards to put into my craigslist-facilitated homebrew CCNA lab, which includes a couple 2811s. Had no idea what I was doing until now. Thanks for your help!
