The tone generator is a little box with an RJ11 plug in parallel with red and
black leads with alligator clips. The tracer is an audible probe that can be
touched to a wire or punch block, or held near.
Am I missing a feature, or do I just need the proper procedure. Like only
connecting one lead of the tone generator? Or connecting the red and grounding
the black, something like that?
On a 1000 ft cable, the tone will inevitably bleed to the other wire in the
pair I think. There’s no doubt I’m on the right pair, not sure about both tip
and ring having continuity.

My tone tracer can isolate individual wires. Does yours have that option?

Anybody remember your POTS troubleshooting skills?
I’m trying to get an alarm system to work from a VoIP ATA over about 1000 feet
of convoluted wiring at a farm, a combination of overhead and buried. I get
tone on my tone tracer (Tempo brand) but 0 VDC on a buttset or voltmeter. It’s
too far for my Fluke cable tester which is meant for data cables.
I suspect one wire in the pair is open, but I don’t know how to check this with
just a tone tracer.
The alarm system just calls and plays a recorded voice announcement, so the
VoIP part shouldn’t be tricky at all, not like FAX machines or alarms that use
modems. But it can’t even seize the line and call out.
