If you really want a wire circuit, for long-haul or short-haul,

Sorry, I meant "short-haul" and "long-haul" in the electrical sense
for the length of the cable line between two devices speaking the T1
line format (B8ZS).  Some documentation I have read refers the to the
two T1 types DSX-1 and DS-1 as short- and long-haul.

Going Wireless is not an option since the distance will be the same as
between major US cities.  Going ADSL is not an option because of
reliablility issues and its 'hackish' implementation.
