If you get a Copper line test error, try the test again with all equipment unplugged, and the NTE5 faceplate removed as the fault could be caused by local wiring or equipment.
==More info on Loop and resistance faults
Loop fault is a symmetric low DC resistance between A/B wires in the pair. Rectified loop fault is an asymmetric low DC resistance between A/B, as-if there's a diode shorting the fault.
