I agree with partial's post above - remove all wires except the pair connected to terminals 2 and 5 on both the NTE5 master faceplate and the extension faceplate and hopefully the problem will be fixed. The bell wire etc. probably wont be needed in the future anyway: http://www.kitz.co.uk/adsl/socket.htm

Good luck.

I think the, or one, point is to make sure the removed wire isn't touching T5 when reassembling. Though cutting it isn't a good idea.

OP doesn't state that he has a filtered faceplate on the NTE5 but I would imagine that he has since the VDSL doesn't seem to be affected by any possible issues with the extension wiring. And as you say he must be very careful when removing wires and tucking them away

Unfortunately, I think you will find that anything untoward to the property, contents etc, remains your responsibility until the the agreed Date of Entry etc.

The easiest advice, is to remove all extension wiring from the NTE and levant at that. There is clearly power nearby as the FTTC is connected there, so put the base station there also. Sorted.

You seem to have ruled out the obvious issue, your phones. It really would be worthwhile trying at the test socket.

Very, very occasionally this fault can be due to faulty exchange PSTN equipment.

If this persists, get PN to raise a CDTA task.

It's worth testing a few times as depending on the equipment in the exchange it could be intermittent due to the way the MF4 receivers are selected, also if it's faulty exchange equipment then other people on that same line concentrator would probably be seeing this problem.
