DSL phone line

We just switched over to DSL from modem on home computers. Put DSL filters
on the handsets in the house and also on the cord going to the computer
modems. When we try to receive faxes only one of the computers will even
attempt to "answer" the call. Is it possible that the two middle wires that
we are using on the wires running through the house are reversed on the
non-functioning modem? Both computers could previously do this. The
suspect line can operate a telephone no problem. Seems odd to work on one,
but not the other. The junction box on the exterior of the house has red to
red and green to green, haven't yet figured out which connection goes to
which outlet. Should I randomly try reversing some wires or does it even
matter?

The polarity of a home phone line hasn't mattered since the early 60s. You
have some other problem like a broken connection through some of the
filters. Try putting a phone where one of the non-answering computers is
connected and see if the line is really getting through that particular
filter.

I did and it does. I also swapped the filters and it did not make a
difference. Both computers are similar and I think have the same modem.

The polarity could be an issue, answering, automation machines like Faxes
and the like used to detect the phone polarity to indicate an
on/off hook on the other end.
the polarity used to flip when the party on the other end picked up
the line and when they drop the line, your polarity would switch back.
This is how answering machines can detect you dropping the line and
not complete the answering message.

I don't know if your fax machine is actually detecting this. It may
think it's already connected.

These polarity changes have been designed out of newer switching
systems since the early 80's....however, if the CO is old, it will work
as described.

That's the Central Office at the telephone exchange. This is where
all the telephone signaling like ringing / ringback, battery are created.

Well, that wouldn't be my problem. Major city, recent growth, dense
population, I'll bet the CO equipment is less than 10 years old.

I'm willing to run over and turn on the second computer when I have to.

It's possible I inadvertently changed a software setting when I added the
wireless card and made a new connection.

If you were asking about a remote controlled power switch, there are off the
shelf solutions such as the old X-10 powerline controller and an appliance
module or their RF equivalent version which comes with a key fob
transmitter.
You could also decode touch tones and activate an outlet though this
solution
will require some engineering. Lastly, a length of CAT5 cable could be
used
to carry the control signals in a current loop for a very long distance as
well.

How's that workin' out for ya, filtering out the digital part of the signal
before it gets to the computer?

Mostly good. The digital part of the signal goes directly to the wireless
DSL gateway modem/router for internet connectivity. The filters remove the
digital part to the in computer-modem so the XP fax console should work.
I've got a 50% success rate. Lately that's typical for me.
