With that short a circuit, you can run LADD modems (Local Area Data
Distributors) which are meant for four wire metalic circuts.  Over
three miles of wire you can easily do 19.2kb.  Modems of this type are
rather in-expensive.  I ran two offices tied together by this method
for several years and it worked just fine (Note, LADD modems come in
both sync and async models.)
