My comment was home phone "wire" (singular) + DSL wire (singular) = 1
standard household phone wire pair. Maybe could have been more clear. I
meant "each" wire inside the pair. You (and Peter Gottlieb) read 2 separate
pair of wires - I think.

There's no way any phone service can use a single wire. Phone service, like
electrical service, requires two or more conductors. In phone parlance, this is
a "loop". In electrical parlance, this is a power and neutral. Now. The typical
"drop", that is, the cable coming into your house, contains four wires. Enough
for two telephones.

Now I'm confused. Is my DSL running at higher frequencies, over the same
(single) wire strand that my voice is running on?

Most (or all) DSL uses higher frequencies than voice and runs on the same wire
pair as your voice connection. I have never heard of a subscriber DSL line that
requires 4 wires, though some other types of digital lines do.
