    Can you test for the presence of DSL signal on your phone line with an
    ordinary 100MHz scope? If so what do I look for?

    A big, raunchy looking signal that's clearly not audio.

    I think you could rig up some kind of inductive probe.

    Just use a two channel scope, put one probe on "tip" and the other on
    "ring", and sum them together (or subtract one from the other-I forget
    which because its been a while since I've done this kind of stuff.)

    Subtract, or flip its phase, if 'ordinary' scopes have dual inputs
    these days.
