Matt,
Note: if the carrier will only give you a G703 (balanced or
unbalanced) interface, you may want to order a G.703 network module
(NM-1CE1B or NM-1CE1U). In the U.K., we got an X.21 handoff from the
carrier; however, the Promina conversion unit they used to convert from
G.703 caused us to lose two DS0 channels on the E1. Int this case, the
carrier was Concert and the E1's were between France and the U.K. The
French side of the circuits were able to give us all channels with an X.21
handoff. So, bottomline, I recommend finding out what the carriers
prefers and configuring your router with the appropriate interface to
match. I.e. for X.21 and V.35 standard old serial module (NM-4T, WIC-1T,
WIC-2T, etc.) or for G.703 use a channelized E1/ISDN PRI interface
(NM-1CE1B, NM-2CE1B, NM-2CE1U, etc.).

Matt,
WIC-1T will do the trick. Just make sure of how the provider will terminate
the circuit. You can usually ask to have it terminated as X21 - 15 way
D-Type, so a standard CABX21MT cable will do.
Another alternative is that they terminate it G703 coax and you use a G703
to X21 converter.
