now its all good I would leave as is, plus I think having the modem separate is superior.

Thankyou Chry & think that's good idea sometimes curiosity gets the better of me.

Reed Soloman (RS encoding) means that redundant data is carried 100% of the time, so if the line isnt erroring then that redundant data is being transmitted taking up some of the bandwidth and reducing the available sync.

Thanks for detailed answer.  So even if I have not been interleaved Ginp may still give some benefit to sync speeds?  I have approx 100 ES per day and 2 CRC errors per minute but lost approximately 40% download sync due to crosstalk.  TIA.

RS encoding - Error Correction - is turned on at the same time as Interleaving, as theres not much point using interleaving without it.

So no not much benefit for lines which currently dont have any form of DLM intervention and these may take a small but negligible hit.

There's also some good/short lines that dont need any error protection or error correction which wont really see any benefit.

Having just installed dslstats I was very surprised to get this on an 8800NL router as the cab is Huawei and even though I started with an ECI modem I would have thought that the Mk2 version would have been applied. Note that it is a very new cab (only a couple of weeks old) supplied under BDUK

The newer cabs and those lines which have had a reset/migration are the last to be done.  Since mid Jun its been implied that those 'catchups' will be done after all the other Mk1->Mk2 conversions have been done.  It was estimated that these would take a couple of weeks and eta for completion was mid to late July.   The last updates were in this post here, although it was in the main thread that I hinted eta for full completion was late July.

We're currently seeing those final lines being upgraded and so there cant be many more to do now. 
Trying to make some sort of order out of no actual conclusive data, it appears that they may be doing the catchups in chronological order, so the fact that your cab is so very new means that it may be one of the last to get it put on.   There are still lines being updated every day, there were a couple more done today on MDWS funny enough at about tea-time.  I think there's only about 3 more on MDWS left to be done now.

iirc it was the 12th Jun that I saw the first of the 'catch up' batches start...  and going off the indication of only 'a couple of weeks to do the catch-ups', hopefully it shouldn't be too long now :)  :fingers:

Hello Kitz I waited 9 days after G.INP Mk2 was enabled on my line before testing out the Brightbox2 and it comes as no surprise it's working well with G.INP have a sync rate of 37579 that's 2000 Kbps more than the HG612.

It's kind of funny I started of with a DS sync of 27000 Kbps over 3 years ago on FTTC and now it's increased by 10579 Kbps were as all you here theses days on FTTC is users sync rates are lowering due to crosstalk.

What the hell is going on it's seem my line has had a resync RDI 1 at 00:27 the sync has increased but much lower SNRM is this the effect of vectoring  :-\

That snrm is very low, but nice increase in speed, will it last and is it vectoring???

might have been an idea to leave it as g.inp kept your error rate low even with the lower snrm :)

I'm to cautious Chry, indeed g.inp was keeping the DS error rate low but the interleave depth went up from 8 to 16 during this odd event, I ran a speedtest it showed a thoughput of 37995 Kbps the highest ever seen on this line.

But I can see the US DLM error status has already entered into an amber state on the bottom (stable) if i had g.inp on the upstream this would not happen.

G.INP has now been re-enabled on my line but only on the downstream.
