I've just received a text from BT ststing:

Hello, BT here. We're sending you an engineer on Monday 03/04/2017 between 1pm and 6pm. Our tests indicate an internal problem so we recommend a check on your equipment.

How can they say it's an internal problem if nobody has been? I've tried 3 different modems and another wired phone straight into master socket and the noise is still there. What elsr internally could cause cause this? There is no extension wiring in house - just master socket (Openreach Nte5 Mk3 type) with modem and phone plugged in .

They're mentioning the £129 charge again so that is making me double check myself!

They are just covering their [censored], no hard fault detected on a remote test ..... You have done all that is required to prove it isn't an internal problem, therefore no charge to follow.

Go enjoy the sun.

Brill - cheers. I'm just being paranoid now.

I'm taking your advice and getting out of the house

Good news - Engineer has just been.
Bad news - no fault found

What he did say is that he was talking to 2 other engineers at the exchange before he left to come to my house and they had just fixed a joint in front of my cab where they did the uplift work last week. He reckons this has also sorted my job out as the crackling has gone.

Only thing is - he can't request a DLM reset because he was booked for a line fault. I told him that the CS peeps were due to ring me back later to check on the progress and he said they can do the DLM reset for me. He did find a slight H(???) error but nothing that he could do anything about as it looks to be 490 meteres away - which is between the fibre cab and exchange.

He was a nice bloke and showed me the map of where my line goes after it leaves the cab - it actually goes the opposite direction which explains the higher than expected attenuation.

I also found out that one of the top fibre bosses in Openreach owns a holiday home a few doors down from me - I'll be introducing myself next time he's there

Hmmmmmm ......

Plausible I guess.

He won't have been given the OGEA reference if it was (what sounds like a CIDT task) I bet they don't/won't/can't do the reset. When they ring make DAMN sure they WERE aware of the crackling previously hence THEM making the booking ...... get a note of whom you speak to and get them to confirm NO CHARGE.

He sounds like a [censored] to me TBF...... He could see an HR on the E side and was unable to just go swap that out BS, an E side swap is a simple clear and well within the remit of any CA lightweight.

The 24 million dollar question is, has the noise gone, and what do the stats look like now ?

Noise definitely gone now - it was really bad at lunchtime when I came home but that was apparently before they repaired a joint.

BT have also just rung me to make sure issue is resolved and have performed the DLM reset after I asked them to! What they did say though is not to reboot router for 72hrs - is that correct?

As I can't reboot router, stats are still the same:

Can the DLM reset really take 72hrs and will it just drop on it's own in that time and remove the banding?

The BT rep just fobbed you off. They can't do DLM resets on fibre, only ADSL. A DLM reset would have triggered an immediate resync.

Just spoke to them again via online chat - they reckon it's been passed to another team to do the reset which will happen overnight. They still reiterated that I shouldn't disconnect router for 72hrs afterwards.

The don't reboot is done to avoid those who can't wait and keep rebooting to see if a change has happened, and this ends up triggering DLM to curtail you, so don't fiddle is best advice.

OK cheers. So have I been fobbed off by both Engineer and BT CS as J0hn83 suggested?

I'm pretty sure in my last house where I was also on FTTC, I definitely had a DLM reset.

Zarjaz - what's your take on this? Could the DLM reset have been set to trigger overnight?
