Line Diagnostics: Difference between revisions

In this case, report the fault to your phone line provider, if this is BT Retail, then you can report online: https://www.bt.com/faults
 
The copper line could come back with other outcomes, such as:
*'''DIS''' The test cannot get a capacitance reading of your line. You probably have no dial tone. It's broken somewhere, somehow!
*'''LOOP''' The 2 wires that make up the line are in contact with each other and are causing a loop.
*'''Battery Contact''' The line is in contact with another line, perhaps due to water, or bad insulation
*'''Earth Contact''' The line is going to earth. The line may be damaged and wire touching earth somewhere
*'''Rectified Loop''' a one way loop - check internal wiring before going further.
*'''High Resistance DIS''' Both lines have high resistance - some connection problem along the line.
 
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.
