newt you can but i expect those profiles to not be used on lines which are deemed unstable so not on interleaved lines and i think with fast path they may not be happy of the risk of high errors which is why i believe ginp to be a requirement

On my line I noticed some of my recent new crosstalk has gone, the affect is not big tho and it benefited the upstream snrm more than downstream.

Interesting. Just seen some graphs claiming to be a sky vdsl on eci cab with a snr of 3.3db on the ds with an increased sync on the ds after the resync. Just happened today. Asked for further stats off the modem to be sure if its the correct cab. ... asked him to check if g.inp is on or not too

Heres an eci line on 3db by the looks of it. DLM  stepped it down from 6 on the ds today to 3.2.Rise in sync and  max attainable.. no g.inp though which seems a little odd ?

that sort of thing can happen with a power cut or similar event, I dont think is any 3db rollout on ECI yet and if there was we should expect a step by step migration so 6db -> 5db > 4db > 3db not 6db > 3db.

I think they will be waiting for g.inp first as well.

no historical data for the account, so I am very far from been convinced.

where are those rrdtool graph from? beezer is on 3db already when he first started plotting on mdws.

His most recent resync was at 14:35 before he started uploading at 19:31 and it was an LOS.

I asked him if he would like to upload as he had not heard of mydslwebstats as I was interested in the line stats after seeing the graphs etc..

Not sure what this is, maybe my upload just came off being interleaved but my hub rebooted twice around 2-4am and my upload went from 14Mbs to 21Mbs MAX, the actual data rate is 20000.
Download didnt change stayed at 67370 / 67602

noise margin is: 6.2 / 6.1

The lower dB DLM profiles move in 1dB stages. A jump to 3dB is a classic power cut/DSLAM reboot. The DSLAM firmware is still 206 also. I would expect to see a newer firmware testing G.INP for an ECI line to have a 3dB target.

OpenReach skipped ECI users from the 3dB rollout because of the lack of G.INP. Seeing as though they appear to have sorted that out it doesn't make sense they wouldn't wait for the G.INP rollout to apply the 3dB changes.

Is there any more news on the ECI G.INP fix?
Obviously this needs sorting before the 3db profile issue can be addressed on ECI cabinets.
Much talk in the spring of a solution being piloted over the summer & possibly rolled out this autumn.
However there's been no reports of anyone having had it turned back on, which is odd if they are actually testing in the field.

There is a thread, G.Inp on ECI Possibly Delayed, on that topic in FTTC and FTTH Issues.
