Each POTS (Plain Old Telephone Service) line takes one copper pair. The
wiring inside your house probably has two pairs, which can either be
used for 2 lines or for 1 line plus power to light the dial of your
Princess phone. If your wiring is of the right vintage you might even
have the old transformer for providing the power dangling somewhere. The
wiring up to your house probably has some even number of pairs. I think
I have a 4-pair and a 6-pair at this point, though most are no longer
used (I'm down to a single POTS and a single T1, way down from my high

Well, pretty much unchanged other than that all the local exchange
carriers that actually run copper wire to houses are eager to get out of
that business to one extent or another. I don't follow this closely,
but I think AT&T is the only one to have actually gone public with a
request to the FCC to set a date when they can drop POTS lines forever.

Hmmmm....if you're doing the standard thing, and porting your phone
number to the cable company, they'll have to put some equipment of their
own on or in your house. They don't really take ownership of the
"line", just the number.
See if you can get the tech to make real sure that your two inside pairs
are well isolated so maybe you can get rid of the problem of ring
voltage leaking from one to the other. He'll probably just detach one
of your inside pairs from Qwest and hook it up to his box, assuming he
doesn't just wave his hands and tell you plug your phone in "here" and
