The T1s just need to match settings on each side.  Same coding and framing.  The same DS0s assigned to the FXS and FXO.  One side will need to be set to provide timing and the other side to receive it.  At that point as long as dial tone and talk battery is coming in on the FXO side the connection should be fine.
