New BB FEC errors

Like I say, it really depends on the engineer you get.

If you have enough (like I have), you'll eventually get one who will listen to you and do something even if the tests pass.

The most stunning thing about OR is how they all the time say that their tests passed, so there's no issue. If there was no issue, why would I have called you out...

Yeah, as mine did, but he did make it clear if it was outside REIN they really can't do anything as diagnostics shows the line is completely fine on their end (he called them up and got them to check).

Interestingly, I no longer get 73mbps even with interleaving off, I get 69 or so now. Must be some few extra folks on the cab now instead of just me.

Openreach have a dedicated REIN team so they can do something but they're very hesitant to.

Outside REIN is normally beyond their control even if they know what is causing it. Something as simple as company/office block next to the exchanging switching several floors of lighting on can cause it and there will be nothing OR will do or can do. Same goes for road works. Having worked for OR for several years previously i can categorically state unless it is something OR have control of REIN issues are not normally fixed.
 
I will note that I live in a small village, so it won't be anything like a company doing it.

I don't know who would turn on something at 8-12/3 every single day that could bugger up the noise on the line that much either.

It doesnt take much, another example if you had roadworks (lets say they are painting the road markings) and come the end of the day they leave those little lantern like lights that flash on and off in orange near or on top of the cabinet over night, that in theory could even cause it.

The list is endless, a person with HAM radio living near the cabinet that uses it same time each evening could cause it.

I have even known street lighting to cause REIN issues.

Well, so far it's been mostly quiet this weekend, only 1000ish ES per day, most at the nighttime, so less than before. Perhaps the pair switch at the DSLAM did something, so that it's not as susceptible anymore.

In any case, for now it's fine so I haven't been able to confirm REIN through the radio. Will have to leave the case for now until it becomes a problem, and just hope that if it does BT hurries up with the bloody G.INP installation.
 
A bit difficult to get ones to you from before the pair shift, but sure, I'll show you the current ones:

At 23:00 hours on the 8th so it's normally in the middle of when it happens.

There's some bad noise showing up on the QLN there. Hlog looks very good actually: looks like no HR faults are on the line now.

Looks to be a REIN issue then.

Yep, and since it has been pretty quiet the past few days, I couldn't isolate if it was coming into the house or coming from the house.

So BT will phone again in week when I have a bigger sample size, just to make sure.
 
Oh for the love of ****.

Two spikes today, at 17:00 for about 500 ES, and now for the past hour it went to 1200ES!!!!!

Hrm, looks the same as the other images. This is not the usual time it happens, and it only happened for that hour (and 5pm, but 7pm was 4x worse). Pretty quiet as soon as 8pm hits.

The Hlog won't change BTW as it's only updated at sync-time.

Tone 2900 to 4000 (approx) seems to show some quite severe REIN. The fact the spikes are so evenly spaced would seem to suggest some kind of faulty switched-mode PSU.

Could there be one of those in your house?
 
Ah, fair enough then.

Well, I'm still not sure if I have any that are specifically on at those times that would cause it, so I'm still in the dark.
 
Is the router located near anything else electrical apart from the computer? NOT just stuff with a conventional plug on it but anything else like heating systems.

I personally given the times you have mentioned would guess that is outside noise.

It's near a couple of extension sockets which includes a small mini fridge, however they're on 24/7 so it would stand to reason that it should occur at every other time too.

I did have the modem away from them before I bothered to screw it to the wall, and it made no difference then.

I guess it is something outside if its within a set time range, but random within there how bad it can be/when it happens. The 5/7pm spikes today were the earliest I've seen it.

Wish I could push for BT to hurry up with G.INP on the cab already. :mad:
 
G.INP won't magically reduce the interference, I hope you're aware of that :)

What it will do is to significantly reduce the errors on the line (I had zero when I had it before DLM was reset) and thus sync speed will likely be higher and pings lower.

Vectoring will help with interference although it is primarily aimed at combatting crosstalk.

I'd be curious to see what the AC balance on your line is like. If you get another engineer ask them as the higher it is, the better the line is at rejecting interference. Above 50 is considered fine but ideally it would be 60+ (I've been told some pairs have AC balances of 80 or 90).

Yeah I know it won't reduce them, it will just act as a soft DLM that won't destroy my ping thus be tolerable.

Vectoring will probably take forever to make it to this cabinet.

Good question, I should see.

DLM only occurs in the early hours of the morning so I don't think it would be that?

It happened at 6am because the ES went over the limit because of the huge burst of 1200 ES in a single hour, noticed interleaving is back on.

If its confirmed REIN there's really sod all I can do about it since it can't be internal. :(
