FAX Over DSL Phone Line

R

RAH

I want to be able to send faxes from my computer using the existing
DSL phone line. I installed a new U.S. Robotics fax/modem yesterday,
and all tests show the modem to be working properly. I am feeding the
fax/modem into a dual DSL filter. One side is the DSL modem, and the
other side is the telephone and fax/modem in parallel.

I have attempted to send a fax both by scanning a document in my HP
AIO printer, and by sending the same document out of Excel 2007. In
both cases, the fax/modem brings up a dial tone, dials the number, and
receives the tone from the receiving fax machine. However, after
about a minute of trying, I get a fatal error in sending.

Does some parameter in the modem need to be changed to be used over a
DSL line, or is this even possible? The analog telephone in parallel
with the fax/modem works perfectly. Maybe a different kind of DSL
filter? This one came from the phone company (Qwest) when they
installed the DSL. OS is Windows XP Pro SP2.

I have read a number of postings on the subject, and the only
suggestion I have found is perhaps try a different filter. I have
already tried that.

Try connecting the modem directly to the phone wall jack (that is,
temporarily disconnect your DSL connection).

What fax software are you using? If you are using Windows XP Fax
Services, a new USR fax/modem "ought" to work, but see

I have tried both the Windows FAX and the BVRP Classic Phone Tools V.
4.21 that came with the modem. Both fail to send. They negotiate,
but the receiving fax finally hangs up because nothing was sent. I
will try the other connections later today when I have some time.

I couldn't find any modems in the Microsoft list of compatible
hardware. It also seems to be only for Vista now. Nothing for XP.

There is a possibility that your DSL provider has chosen to not support Fax.
You might need to ask them about your problem.
Some providers have decided to "optimize" income by charging extra for such
"features" as Fax support.
Normally, if the system works on an analog phone line, it should work on a
DSL line when the proper filter is installed.

That would not seem too likely. Qwest is a major telephone company in
the Southwest. Some time back I was using a standard fax machine on
the same line, but it was before I had DSL installed. I may give them
a call anyway to see if they have an idea. Thanks.

I did try connecting directly to the wall jack with the DSL modem off
and disconnected. No change. The modems seem to talk to each other,
but the fax just doesn't send.

Tried both the BVRP Classic Phone Tools software that came with the
modem and the Windows FAX.

The "Windows catalog" is a bit of a joke these days. There is ONE
faxmodem listed as being "designed for Windows XP" -- the US Robotics
Performance Pro:

If you have been unsuccessful with both Windows fax software and the
Classic Phone Tools fax software, that sounds to me like a hardware
problem. Have you tried faxing to more than one fax machine? If so,
you might want to give USR a call. You said that it was new -- USR has
a 2 year warranty.

No, I haven't tried to fax to another machine. The one I am sending
too is a high-end Canon that never has any problems. I think the
problem is all on my end, and has something to do with the DSL line.
The USRobotics 5699B is shown as a current modem on their site.

I'm going to try deleting the Windows FAX as someone suggested to see
if that has any effect. The poster said sometimes there is a problem
when you have two FAX clients on the same machine.

Deleting the Windows FAX didn't help. Document still doesn't send.

Something else I may try. I have been reading that using a DSL
splitter at the incoming network box gives much better isolation than
using individual filters at each inside jack. I'll give the phone
company a call to see what they would charge me to do that.
