What's happened here then? ECI cabinet. Apart from crosstalk dropping me down over the years I've never had interleaving on:

Virtually exactly the same before and after stats as me and interleaved was applied last night also for me. Also an ECI cab sufferer. Ginp can't come quick enough IMO.
My DslStats showed a mega amount of ES hit 1000/hr at one point, the auto mass effect detection should stop interleave being applied but this has never worked and the ECI cabs are as twitchy as they can be and apply interleave at the first opportunity. I stand by opinion something has changed in this regard in the past few months.
I put it down to the weather and thunderstorms even though there wasn't one near me. If past experience is anything in 10 days or so hopefully it will be removed. Sometimes slower 14 days even 21 days never quicker for me but others it goes after 3-5 days. Looking at the stats the weather continues to play hell with the line I had a 100 ES spike a little time ago even with interleave on unheard of for my line definitely the weather in my opinion. I hope so anyway it better not be a fault developing.
-
Odd. I didn't notice any storms around me recently. Also we've had storms before and nothing like this has happened. Last night my DS Max/Achieved were almost the same - approx 70550 Kbps (as they always have been). Now max DS is 78178 Kbps and achieved is 65561 Kbps. FECs seem to have jumped from the normal too. I'm wondering if something was/is going on with G.INP implementation on ECI cabs. Something happened at around 0100 this morning, and if it's happened to a few people on ECI cabs it must be something planned surely. I'm near Preston btw.
-
I am on an ECI cab too and I have noticed some odd goings on my line as well. Had a re connection the other night interleaving depth got reduced, then last night at 0100, interleaving depth applied at the highest and lost 5Mbps off the attainable and synced lower than normal. Hopefully there is nothing wrong with the rollout, and rather than applying G.INP, applying interleaving instead. However in regards to thunderstorms, I thought that wide area events are taken into consideration on VDSL DSLAM's, by the DLM, or does it not apply the same with ECI cabinets? Sure doesn't seem to be the case with mine, haven't had any thunderstorms in my area but I could see the errors ES racking up a lot from thunderstorms in the midlands, calmed down when they went. I'm on TalkTalk in the Selby York area if that helps.
-
The increased FECs are normal for interleaved. You should also see them for download now I do as soon as interleaved is enabled. FECs are fine they show interleaving is working. Generally theoretically FEC is good, CRC/ES/SES is bad. FEC/interleave should reduce CRC/ES/SES.
Yep no apparent storms, thunder, lightning either but it certainly feels there should be very muggy etc. Don't be surprised if it does start interleave will probably be applied at an even higher inp/depth that will add even further delays getting it removed.
Nothing we can do really apart from leaving it alone. You can try to cap your line but not worth it until the current weather passes and even then I don't like the risk of confusing the DLM.
-
Fellow ECI sufferer. The DLM is much quicker to apply interleaving than the published figures I've seen. I understood it was supposed to tolerate 720 or 1440 ES per day depending on the profile (I'm with BT), but my line regularly goes interleaved downstream with ~200 ES (and 0 SES). Once interleaved it has <5 downstream ES per day, but takes weeks or months to recover fastpath.
G.INP can't come soon enough.
-
It used to be 2880 ES per day! I hope OR just enable/rollout Ginp for all ECI users soon and stop this weird trial that ISPs know nothing about.

I think it still does. There's been thunderstorms here everyday since Saturday (got one passing by that is producing a lot of strikes, near constant thunder at the moment), so far DLM hasn't taken any action. Probably stick the line on interleaving now I've said that lol.
-
I’m on an eci cabinet roughly 150m away line is always rock solid 67/20 lived here just over a year and always on fast path with low ping of 8, as of early hours of Monday morning roughly 4.30 had a resync dropped to 63/20 with a ping of 20 which is very unusual, with sky and it’s always spot on to be fair! Are Openreach doing something behind the scenes hopefully going to give us 2nd rate users compared to Huawei G.INP at last as this trial looks very promising, I was on the last trial a few years ago and worked perfect for me speed gain of 7mb on download and ping went to 5 and was rock solid until Openreach pulled it :(

Well I was wrong. Line is now interleaved. Had 3 storms yesterday, looks as though there is more to come over the next few days.

Judging by the jump in threads mentioning the same issue i'd hedge bets that its a wide spread issue and will probably correct itself given time. Your speed is likely to increase when interleaving goes away.

Thanks 😊

I'm not convinced, at least on ECI lines. When I got my Plusnet line Interleaved by trying to push 3dB SNRm, when I removed the SNR modification it didn't show any signs of removing Interleaving again.
With my Zen line banded, I'm not hopeful it will remove that either. Although to be fair, its syncing at 6dB so annoyingly its within DLM specifications, I just happened to be running it rock-solid stable at 3dB before the storms.
-
Perhaps there is a long term impact caused by forcing a 3dB sync, all the more reason for FTTP to be rolled out faster. My plan is to move somewhere with Virgin broadband.

Frustratingly there's a Virgin cabinet in visible range of the BT cabinet I'm connected to, they just didn't go past the local park leaving 1/4 of the road not covered.
Though not as frustrating as FTTP being delayed here 2-3 years.

That sucks, I know Virgin is in and around my area also but only certain parts. I plan on moving in the not too distant future (possibly next year or so) and I plan on moving to Virgin media in the new property.

My son has had similar experiences with Virgin cable in both of the properties he has occupied, cable at the end of the street but not continued down to his properties.
On enquiring, he has always been told that the issue is both cases was no footpaths which indeed was physically the case, local council won't permit Virgin to cable trench on the road within housing developments.
-
given the reports of it kicking in with only 200ES, it would seem even a quick action to turn off the modem, a few minutes into a storm may not be sufficient.

Well after nearly 7 days being interleaved and speed dropping from 67/20 to 63/20 had a resync this morning around 5.30 and my speed has gone to the highest I’ve ever had in a year living here now on 70/20 and ping is now 8 from 20? Just wondering if G.INP has been applied to my line, unfortunately I’m using sky’s sr204 router which tbf Is Rock solid but very basic and no way of finding out but it’s looking good atm hopefully it’s been rolled out 😁

Excellent news. I'm still interleaved, so fingers crossed for G.INP for me soon.

Or maybe SNRm 3dB was applied by DLM which does normally means higher attainable / sync. speed... :hmm:

No noise margin sitting at 6.2db down and 12.2db up I don’t think they have applied the lower noise margins to eci cabinets yet just G.INP for now as that was hard enough for op to get right but looks like they have this time round 😁
-
Ah ok I thought the router don't show SNRm, so probably G.INP is enabled in this case that would be the most logical reason for the higher speed. Glad it is finally available on ECI :thumbs:
-
The more likely explanation is the line has simply returned to fastpath.
It went interleaved due to high ES.
You would then expect it to revert to fastpath.
The fact you synced a little higher doesn't mean G.INP is enabled.
Not seen anyone on Sky with G.INP.
No mention on their forums or here.
It needs them to opt in.
-
So, at 6am this morning I am back on fast path, still no GINP though (BT - ECI Cab):

Got a resync last night but still on interleaved so back to waiting 10+ days again I guess. It is stupid I should just be able to login and turn interleave off. I was on 29 ES before the resync. That is less than 3 per day. Better yet just put Ginp on all ECI lines. Convinced it was the weather last night causing the resync I will probably have thunderstorms in 9 days stopping it being removed again.
-
I totally do not understand the DLM.
Two days ago I got a 100 ES in an hour and was thinking that is me waiting 10 days again but no it reset to fastpath last night. Yippee.
I have now given up trying to understand how the DLM works.
I just hope ECI GINP passes the trial and gets rolled out to me soon.
-
After last nights severe lightning storm I am back to an interleaved connection. I wish ECI ginp would be enabled but not sure it would have saved me. I had a hour with 2000 ES beat that :)

Yeah me too. I've never seen a storm like we had here last night before. Lightning and thunder for hours - horrid.
-
A resynch last night, still interleaved. Downstream SNR margin has never been as low though.

Yes I'm also still stuck on interleaved.
It usually gets removed after 10 days on my line but every so often it takes longer.
I did get a resync 5 days or so ago but it didn't remove interleave.
I suspect the stormy weather is resetting the counters the DLM uses to decide to remove itself.
Looking at my stats I have had a total of 5 ES and a few more SES since the last resync 5 days ago but I suspect he DLM doesn't use that metric any longer to decide.
If ECI had ginp I suspect it would be nowhere near the problem on my line but the chances of Ginp is gradually disappearing I suspect for us eci sufferers.
-
Conversely I am back on fast path, after several months interleaved. No idea what has triggered it - the line conditions don't seem to have changed.
-
There's no way to force fastpath, right?

By leaving modem-router connected not keep disconnecting it, let the DLM do it's job.!

Thankfully back on fastpath took a month this time.
The last few times we've had thunderstorms it has only taken 10 days or so.
I'm sure GINP would help - I can dream.
