Hello
Martin. I certainly
do remember you from last summer's treadmill issue.
Over the last three weeks the line has become noisy <snip>
To which type of noise are you referring? Audible, when using the telephone or EMI/RFI as shown by a well depressed SNRM? I assume you mean the latter . . .
Whichever, have you performed the most fundamental test -- plugged a corded telephone direct into the test socket of the
NTE5/A and performed a aural line quality test?
Has there been any change in your DS or US line attenuation? If yes, then that is a good indicator of a (developing) line fault. If either of the attenuation values is different (each time it is checked) and there is a hiss, crackle or other audible sounds when using the telephone then that is highly indicative of a (developing)
HR (high resistance) fault. If that is the case, it should be reported to your telephony service provider as a telephone fault (do not make any mention of the broadband service) and they should book the services of an
Openreach network (telephony) engineer to resolve the issue.
