Errrrrr. Make sure that your signal is or is not present in the regular
telephones associated with that line. The susceptibility may be in the
modem or the telephone instruments rather than the telephone company cable
or drop.
You can check this by using a proven rf immune telephone set connected
either at the normal jack inside the house or at the customer access point
of the SNI (Standard Network Interface) mounted at the side of your house
with the inside wire disconnected.
Have someone listen while you're transmitting. If the noise is present on
that particular telephone, then you can blame the serving telephone
company's outside plant. Otherwise, the trouble is either the modem,
telephone, or inside wire.
In fact, that's probably where it is.

Subject: [CQ-Contest] Telephone Interference
Hi All.
I posted this yesterday, but it never showed up on the reflector. In
fact, in two days, I have only seen one message, K3ZO's (very
interesting one) on the cq-contest reflector.
Anyhow, after the contest, I found that I was getting into my sons
computer thru his phone line. Not unusual you say? He lives two houses
down the street from me!! Are there any good filters to go on the phone
line that I can get to keep the rf out of his (and mine) computer.
Undoubtably, it is getting into the fone lines on the pole, and going
into his house. Does the phone company make any thing like that? Thanks
and 73
