Re: Generic tech question-dsl but no dial tone on one extension?
Because your other two extensions on the exact same circuit have dial-tone, you can pretty much rule out a short or ground.
You most likely have an "open". DSL will sometimes work over a circuit with 1 entirely open wire (clean, broken) or a "dirty open" (corroded, loose). Dial tone will not work at all over a clean open, but might work intermittently over a dirty.
The first thing you should do is examine the jack closely for smashed pins. Remove the jack from the wall and check for broken / loose wires or corrosion.
If the jack is O.K., you should do a visual inspection of the wiring for that extension. Look for the obvious (animal chews, carpet tack strip, outdoor damage). If the extension is not "homerun" back to the demarc, you will have to segment and isolate at each place it stops (last working jack in the chain is always a good start).
If you can't visually track the extension, you probably need to call for help.

| Sigh again. "Dirty open" seems likely.
I moved the fax machine to the jack with dial tone, installed HP's bloated software on the computer in that office, got it up and running (and receiving and sending faxes). Then I took an older printer/fax back to my office, plugged it in and on a whim connected it to the jack AND attached the handset - and there was a dialtone. The difference? 30 minutes of dry weather. Since the jack is on the third floor, with a straight run down to ground level outside, this requires extension ladders I suspect. The jacks are probably not in series, by the way - we may have had the installers do a split down by the NID to run up to my office, since one jack is on a north wall, and one is on the south. |

@cgocable.net | Like PE said only one side of circuit needs continuity. Up here at least, tip side.
As you got dial tone the next time around check the centre pins in the jack for corrosion. Green look to them. May have cleaned off on contact. |
