When I had my second line installed, I specifically requested a
completely separate line coming off the pole because I had heard of
problems like the above.  The phone company didn't seem to mind, and
there was no additional charge either.  Some months later, someone
pointed out that once my two lines connect to the pole, they're
connected back to a single line -- with everyone else's in the
neighborhood to boot.  Makes sense to me, but then I know next to
nothing about phone systems.

I've never had a problem with crosstalk on either line, but that may
only be coincidence.  Does having the separate line really make a
difference?
