Question : Can you use a VWIC-2MFT-T1 "2 port voice interface card" to terminate 2 data T1's to?  If so, how do I configure the controller 0/3/0 & 0/3/1 interfaces to accept IP addresses?

Hello, we have a VWIC-2MFT-T1 dual voice T1 card in a Cisco 2811.  I was asked to use this one and only card to configure 2 data T1's on.  The router recognizes the VWIC card as Controller 0/3/0 & 0/3/1 interfaces.  I rarely work in the voice world and have never configured this type of card.  I'm used the the router recognizing T1 interfaces as serial interfaces.  Thanks.

Yes, you can!

controller T1 0/3/0
 channel-group 0 timeslots 1-24
controller T1 0/3/1
 channel-group 0 timeslots 1-24  <== This command creates the serial interfaces

interface serial 0/3/0:0
 ip address 1.2.3.2 255.255.255.252
 no shut

interface serial 0/3/1:0
 ip address 1.2.3.6 255.255.255.252
 no shut
