Connecting two 1751 w/serial interfaces

[dal]

I am attempting to connect to 1751 routers w/serial interfaces via t1 line. Router "A" (host side) is identical to router "B" remote side. I want to keep them on the same subnet for simplicity purposes. I have performed this feat with csu/dsu modules in the past, but never with serial interfaces. Host side has an internet gateway seperate from the router itself - which the remote side will need access to also. For the life of me I cannot figure out what I am doing wrong. This is the configuration from router "A", router "B's" configuration is identical except for the BVI 1 IP address is x.x.x.22 instead of x.x.x.21. Any help is greatly appreciated.
