Are they not able to see the resyncs?

They should be able to .....

Reason I'm being cautious about getting an engineer is that I can't afford the £129 if they don't find a fault.

I fully understand that.

See my reply from last night.

Sorry, missed that last night!!

I think I'm going to leave it a day or 2 to hopefully settle back down. FECs down to mid 50s and no restarts for couple of hrs now. No noise on line and neighbour texted me and said Openreach were back at cab earlier.

Speeds still down but I'm assuming it's because INP is still high at 52? It's usually 47-48.

Engineer re-booked.

Got home form work and crackling was so bad, I couldn't even ring BT so had to use online chat! Also, several more resyncs this afternoon.

Apparently, according to CS person I spoke to via chat, Engineer won't need to visit house but I made sure I gave my mobile number anyhow and asked them to ring me 15 mins before.

Going to keep this appointment no matter what this time. They say estimated fix by 01/04/2017.

Good luck.

Thanks I asked for a Saturday appointment and they said he probably won't visit the house so haven't been given a time. I'll post back here with verdict once engineer has been though.

Thinking about it tonight, the crackling on the line seems to be corresponding with the heavy rain we've been having over the past few days. Had the heaviest rain I ever seen about 20 mins ago and had another resync, this time with reason 20 20 - any ideas what that means?

any ideas what that means?

It could mean that your theory about the cab uplift is coincidental .... Is your house fed overhead ?

Nope all underground. I'm literally 150m from PCP but my attenuation has always been around 18db which I think means my line is about 350m?

There is an SCP up around the corner so I'm not sure if my line goes up to that first then back to my house.

Depends on the wire gauge - to an extent. However, 18dB is nearer 500m. At 440m, mine is 16 dB.

Right so even longer than I thought OR down to the gauge! I'm going to quiz the engineer if he does actually come to the house as the last one told me my line goes straight to the cab which, as I said above is about 150m.

Just did a quick measurement via Google Earth (I know this is only rough) but even if the line does go past the house, up to the scp and then back to me, the distance is only 320ish metres.

Line is terrible this morning - can't use phone due to crackling, G.inp is now enabled up and down and there have been 15 resyncs since this time yesterday.

I better get used to it as engineer isn't due to look at it until tomorrow!
