First, do you get the hum when the DSL modem is disconnected? Second, do
you get the hum when you plug directly into the jack on the CPE (that's the
box that they should have installed that has a jack or some screws in it
into which the internal wiring from your residence is connected) with
everything else disconnected?
If you get the hum directly on the CPE when using an ordinary phone, then
it's their problem and they need to fix it and if they continue to refuse
it's time to talk to whatever organization oversees public utilities in
your state. If you don't get it when you're connected directly to the CPE
but do get it with the DSL modem completely disconnected then it's in your
wiring, which, unless you are paying them a premium to maintain said
wiring, is _your_ problem to deal with. If you're getting it only when the
DSL modem is plugged in and the modem seems to be working properly then
you've likely got a bad filter, which you can replace for a very few bucks
at CompUSA or Staples or just about anywhere else that sells phones.
Note, once you figure out where the hum is coming from, if it's their
problem then call repair service and tell them that you've got a hum on the
line, don't call the DSL support number because they don't seem to be aware
that they work for SBC--actually having the line checked is the _last_
thing on their list.
