Just this week I have configured a similar module in a 1721 router to connect to an Internet provider. They were using Framed G703. Config like this:
controller E1 0
channel-group 1 timeslots 1-31
This auto-creates interface s0:1 on which all subsequent configuration can be done.
int s0:1
bandw 1920
ip addr ..
I assume that you should configure the interface with your standard Frame Relay config.
Please ask if you require a setup for unframed G703.
Good Luck!
