Answer : configuration of cisco 1800 router for frame_relay

if the CSU is internal it will need to be configured for the proper channel count, and frame type, etc.  Afterwards configure the frame-relay.

int s0/0 (your interface may be different)
 no ip addr
 description Frame Relay Connection
 encapsulation frame-relay
 no shut

int s0/0.1 point-to-point
 ip address x.x.x.x y.y.y.y

You will need to get the DLCI number from the frame-relay provider.  http://www.cisco.com/warp/public/125/12.html is a good place for troubleshooting tips.
