The reason the FCC does not let you connect customer-provided
equipment (voice or data) to 2 party lines is that the central
office equipment on such lines relies upon some jumper wiring in the
individual telephone set for originating party identification.  If
your equipment fails to identify which party it is, your outgoing
calls may be billed to the other party -- toll fraud!  A further
complication is that for incoming calls on two-party lines, your
bell (or ring detector, if it's a modem) must be able to determine
which party is receiving a call.  If your does not, you'll
auto-answer a call intended for the other party.

The prohibition regarding pay phone lines is similar:  If your modem
or customer-provided phone does not collect a dime (or whatever the
initial period charge is in your area) then you are stealing something!
