I can now hear occasional high pitched noises on the QLN test, should I be worried? I've noticed downstream CRC's are starting to be picked up too.

Keep checking a couple of times a day or so. Also check the noise margins with it and without. Preferably make a note of the times, particularly by checking a few times over an hour to get an approximate end time.

The QLT should be silent except occasionally you may get the faintest of faint rustling sounds. Ideally you get a cheap corded phone as well for the test and disconnect any DECT ones.

A later step with a corded phone is to check using the test socket.

Ok, will do. Thanks, Bob.

There has always been a constant but distant noise on the QLN test, I've only noticed slightly more significant noise on it yesterday and the SNR margin's have remained stable.

What's more concerning is the fact that line protection has been working a lot harder than normal all night, significantly higher than previous days.

This doesn't look good... Especially very recently.

Until it presents itself as an issue such as dropping connection, or low throughput, I wouldn't sweat it.

There's no point in obsessing. Nothing will happen until a fault manifests. Openreach won't investigate until you have an actual fault.

Do you think a fault is starting to manifest itself though?

MDWS has a lot to answer for as far as those prone to fixate go.

Sorry, I'm not fixating. What an irrelevant comment. I'm just simply posting updates as things evolve.

You're looking for a fault which isn't there though. Leave it alone until you notice a problem with the connection.

Yes, a fault is developing, it's quite obvious... But, fair enough.
