I would never run phone lines within the same 4pr cable as a network.
the problem is not the ringing current, which is low freq and is usually
a sine wave. The problem is lightning and other fault currents getting
in from outside and ruining your NIC or hub. And then there are the
numerous radio stations that use the phone line as an antenna to get
Remember that ringing current is a differential mode signal, so twisted
pair should balance it out. But lightning and RFI is common mode, and
is not balanced out, it's between both conductors and ground. That gets
into the other pairs by capacitive and inductive coupling.
