For those not familiar with how this stuff works - phone drop wires
consist of a number of twisted pairs - i.e. two insulated wires
twisted around each other into a spiral, before being laid next to the
others and the outer cable jacket applied.

Newer dropwire is like that, but the earlier stuff, much of which is
still in use, is figure-of-eight single pair construction, often of
copper-coated steel wires.
It was supposedly run from pole to house with a few twists - to
prevent it from whipping in the wind, rather than to reduce
interference.
