Have you tried the automated line check? https://www.bt.com/consumerFaultTracking/public/faul...

Are you sure it's not the phone causing the noise?

I've done the line tests before, and they ran a couple this time.

Before the line test would clear up the noise for a bit, but not this time. The line has also gone dead for a couple of hours before.

So with that, and the fact that the BB is affected, I'm guessing that it's not the phone

As you are on "Zen Fibre 2 Unlimited"; and the fault has affected that High-Speed Broadband, suggests that the cause probably lies somewhere on your (extended) D-side line, from the FTTC via the new link to the PCP and/or from the PCP to your house and its NTE, assuming you have checked everything within the house.

What you have described sounds like a bad/high-resistance joint, occasionally going open-circuit.

If your D-side from the PCP to your house has an overhead section, it might be somewhere in that part; but of course even underground cables can suffer from bad joints.

Handy having the video.

If you have to report it again and there is noise during the reporting call, might be worth recording that.

I have an engineer scheduled for Tuesday, but sod's law says it'll be quiet when he/she comes!

When they do come, it is likely to be on a CDTA task (conscious decision to appoint) The very first thing they should do, apart from having a listen, is to make an end to end pair quality test from the NTE with all else unplugged. This will be done with their hand held tester, either a JDSU or an EXFO.

Show a little 'keenness' in what the are doing, "Do you mind if I watch ?" that kind of thing. Watch the results come in on the tester, you'd ideally be looking for 100 or 99% cap balance, and AC balance of 60db or above, and no more than 5 ohms difference (the less the difference the better) between the leg resistances. Ask the engineer to explain all the results as they come, especially if any of them come in with an exclamation mark beside them.

Good luck, hope you get a decent cove !

Thanks Zarjaz, I'll try and get a look at what's going on, if the engineer is friendly!

I haven't touched anything this time, in an attempt to keep the noise there ready for tomorrow.

I'd thought about taking the filter off an going into the test socket, but as I removed all extension wiring after the last time, I figured that it's not worthwhile.

It's worth mentioning that the BB stays connected (mainly) when it's noisy, but then using the phone will almost always cause it to cut out. Perhaps a clue in that?

And would you believe it, a *very* good engineer turned up, and was ready and willing to climb poles and all sorts.

The noise was there, and in the test socket, but all the tests came back perfect....! Perhaps those test units should have microphones

Anyway, he then went on to test the bare wires coming into the house...and no noise! So a new NTE5 front fitted and it seems that all is now OK!

I was hoping my attainable on the fibre might go up to where it used to be, but it hasn't, so crosstalk must be causing that.

We talked about vectoring, and they're getting training on it now, as a vectored line can fail an insulation test apparently.

Happy puppy today!

Let us hope that's an end to it .........

as a vectored line can fail an insulation test apparently.

At present, the only cards with vectoring on them are (I believe) the third gen Huwawai ones, there is a known issue where an end to end pair quality test will show an earth contact on both legs/low insulation. Not a fault, just a PITA.

Not a fault, just a PITA.

That's how this chap explained it, it'll flag as a fault, when there isn't one )

Finger & toes crossed that this is the end to my woes!
