I totally forgot about those. Nice pots line stretchers.

Yes that’s definitely a thing. Did it with Sipura SPA ATA’s a long time ago.
Those don’t exist anymore, so I don’t know what hardware to get today, but yes
absolutely.

I think you can make a virtual pots line using an FXO and FXS adapters over ip

You can kinda sniff along the wire. I would tie the pairs together at the

middle and see which direction the fault lies. Ground each wire at the far end
in sequence and identify the problem wire. Keep cutting the bad half. Binary
chopping. You might be able to put tone on one wire to ground and sniff, or
open the jacked at a mid point etc. Find someone with an old fashioned copper
TDR. Do you only have 2 wire available? Does it read open circuit or does it
have some leakage, shorts or grounds?

Oddly, the customer’s IT guy does have Ethernet connectivity to the barns via
wireless bridges. But they want their barn controllers to also dial a list of
phone numbers using the FAX line in the office.
Either I’m doing something stupid, or the wire’s broken in which case it
wasn’t working over the POTS line either.
Farms can be very old school. Don’t want eFAX. Don’t want voicemail sent to
email, they still use *97. Don’t want IVRs or autoattendants or dial by name
directory. Don’t want computer-phone integration or softphones. And yet the
owner’s son drives a Tesla.
If it’s really a broken wire, then it’s their problem to get it fixed, I just
usually start from the assumption that it was working when I got there and I’m
doing something stupid.

Can you just eliminate the wire and do a wireless PtP between the two
locations? Even if you find the issue with the wire, if it is that convoluted,
it sounds like an ongoing problem potentially.

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.
