I've got about 1000m of multiple-twisted pair PhoneNet cabling with
some segments over 250m. Farrallon says you can go up to appprox.
1000m depending on quality of copper wire (24 guage or better),
and topology ("bus" or "backbone" design is best, passive stars
are a no-no). The only problem I've had is with one long segment
of 3-twisted pairs where each pair was inducing interference on
the others. Apparently this can occur when running the same
bandwidth on all pairs. Solution: run more cable, use some
pairs for voice or ethernet.

As far as I know, both LocalTalk and PhoneNet standards call explicitly
for *UN*shieled cable.
