Not sure if I am making progress, but I at least have traced the line from one end to the other. We had this tracer kit in our tool kit:

I set it up in Scan mode, plugged into the jack at the phone location. I used the tracer and the tone was clear at the TVA50 end of the run. So at a gross level the line is continuous. Do I try testing each individual wire in the 2 pair (4 wire) line to see if one is loose or broken?

It appears that if you set it to Network it would show all wires individual as per the products website. Test it on a known good cable first so you know what to expect.

Well, if the cable is good, you only have the jack, the patch cords, or something stupid. Look at the line cords that make up the patch. Since it's the outer pair, is the cord maybe nicked? How about the "crimps"? Do the black and yellow wires seat all the way to the end of the plug? I had an 8-pin fall out in my hands only took about 3 weeks to find it.

Last, but not least, you could make up a jack with all the pins shorted on one end and meter out the conductors, looking for opens. I'd like to tell you that you can read the voltages on the pairs, but you can't. The voice pair has 38 volts DC, but the data pair doesn't settle. You can read the same 38 volts on one of the data pins to one of the voice pins, but that's not much.

Just wanted to close out this topic and give everyone an update. After various tests I was unable to get a good connection through the existing wiring. There are a few spots where the cable may have been crimped, so I just ran a new line (120', but through an open basement stock area) and the extension now works fine. So now I have an additional new wire added to the spaghetti western in the rafters, but the most important thing is the phone works.

Thank you all for the suggestions and advice along the way.
