and cause signal reflections (near-end echo) which can interfere
with the incoming signal. My guess is that near-end echo which is
inaudible or unobjectionable to the human ear (too low in
amplitude, too near in time to the original transmission) can still
degrade signal quality in a full-duplex modem transmission.
Oh, yeah. They give you some "phone filters" with the DSL modem. What
you should do is install the DSL modem near the place the phone line enters
the house. Cut the wire, connect the DSL modem with short wire to the
incoming line, and put the filter right there, and connect the rest of the
house to the filter. This should greatly help the DSL modem to work.

Of course, this won't do any good for dialup. But, then, I can't even
IMAGINE going back to dialup today. With the typical web pages offered
today, you might take 2 hours to get the first page load from Google!
