Depending on the resolution etc of the JDSU and the distances between the NTEs, it should be possible to check from the various NTEs in the house, with a bit of subsequent comparison of the results from each.

That's from the experience of using a TDR for several years, mainly on Ethernet circuits and occasionally on multi-wire circuits similar to phone wiring, when there were problems on that side of the company.

The TDR, Time Domain Reflectometer, was my "Pocket Radar Set"; and the JDSU works in a similar manner, for those who are unaware of that type of instrumentation.

Saved a lot of time, when trying to locate faults in cables; and also confirming that new cables were properly functional.

Also used it with an oscilloscope, to demonstrate the 180 Degree difference between reflections from Open-Circuits and Short-Circuits.

It may also be necessary to use an extension lead, say 10 Metres or longer, to connect the JDSU to the NTEs, due to the probable short lengths between the NTEs.

This would move the various NTEs to beyond/outside the "grass" distance/area seen in the centre on a typical PPI Radar display.
