I have one phone jack in my "computer room."  The at&t u-verse tech hooked the ethernet box up to this phone jack with a yellow broadband cord.  The problem, I just bought a fax machine and I don't have a phone jack to hook it up to.  At&t told my over-the-phone to install a DSL filter, but when I unplug the yellow broadband cord and plug in a regular phone there is no signal.  What do I need to do?

Was the "phone jack" working as a telephone point before install of your ethernet box ?

If it was installed for your computer,  maybe it is not a telephone point.....

Assuming you have a ADSL (maybe called DSL in the USA) service and it is a telephone phone point then you should NOT plug any phone or fax machine into it without connecting a ADSL filter first,  otherwise you run the risk of damaging your phone or fax.

As you are in the USA,  check this link

Thanks for the reply Kiwiscoota, the phone jack was just a piece of cat5 cable in the wall before the At&t tech came in and attached a female plug.  I just assumed it was a phone jack because of its appearance.

Hi, you may need to investigate how the tech wired that phone jack, I presume he has installed a central filter somewhere, and quite possibly wired the DSL feed from that filter to line 2 of the jack (next pair out from inner pair) and not wired anything to pins line1 (inner pair). He may then have configured the modem to pickup from line2 rather than line1, many modems support that feature.

As I said, you need to find how he has wired the sockets.
