-> Just use modems like USR Courier and switch them to leased line operation.
-> It requires a direct 2-wire connection such as a leased line.

Actually for the distance involved, he would get a 4 wire analog circuit
which would require a 4 wire modem at each end (i.e. Paradyne, Racal
Datacomm, USR Courier's configured for 4 wire leased line operation etc..).
These are commonly used for ATM machines and otehr low bandwidth solutions.
In the US many of these are being replaced by Frame Relay circuits using
digital DSUs because the phone company tarrifs make the digital lines
more attractive. This is because the carriers and LECs want to dismantle
their TDM (time division mutliplex) networks and get rid of all of
those large D4 channel bank frames. But make no mistake, there are
thousands of these currently in use today.
