G.INP

[#1]

I'm just wondering what I will need to do when G.INP is enabled on my line? I have an ECI modem on a Huawei cabinet and so I assume I'm going to suddenly lose ~10 ds when it's switched on ?
Will BT be pushing out a firmware update for the ECI modems or will they need to be replaced? As my modem is locked down I have no visibility of what it's up to.

[#2]

@woodm if all is well when G.INP is applied you shouldn't have to do anything, it's a new Profile that BTO have added not firmware, the cab checks to see what Modem you have if it's G.INP compatible both ways it shouldn't do anything, if it's a ECI modem that can only do G.INP on the downstream like the BTO ECI modem then it should apply the new profile that was used during the Trial, again it shouldn't do anything other than put G.iNP on the downstream.
BTO will start applying the new profile on Huawei cabs tomorrow, no idea when your cab will be updated just need to wait.

Thanks for explaining that. Appreciated.

Eeee by gum, lad! What 'ave we 'ere?    
Definite improvement in ping with the ECI modem.
6ms restored to BBC & TBB.
Not sure why the downstream sync hasn't improved (see attachment with BT IP Profile - speed test is limited by PlusNet profile). I may have to swap the Huawei modem in when I get chance and take a peek at the stats...

I'm assuming my line wasn't included in the trial for some reason and that this is the result of Openreach's 'production' rollout of the new DLM profile; but I don't know that, of course.

[#5]

Does anyone know how long it will take for the new DLM profile to be rolled out nationwide?
No improvement here so far.

Hi interzoom, During the trial it turned out that the profile that BT used had Error correction turned on along with Fastpath while this dropped the latency the error correction prevented the Sync from going back up for some, It's not clear if BTO will / have tuned off error correction for the whole rollout maybe based on what has happened with your line if indeed the new profile has been enabled on your cab  that error correction is still on.  
seems if your stuck with a BTO ECI modem or any other ECI modem that only does G.INP on the downstream  you could very well be with less Sync due to no fault of your own, I hate to see how it's going to go with us ECI cab users i fear the worse.
@tonyAtplus no idea I don't know if there is a time frame set by BTO it could very well be weeks depending on where you are.

I won't be going back to my Huawei 612 3B any time soon I can tell you that much. For me this trial has been another positive step for my long line.

Yes, I'm inclined to stick with the ECI as well.
But still, as I say, the sync should be 80Mbps, so something isn't quite right...

[#9]

Very interesting to learn that people from the trial prefer ECI modem to Huawei following the implemented fix. Would you say that the standalone ECI modem is also preferable to, for example, Billion 8800NL modem/router (or any other modem/router) or very close in performance to it?
Also, looking forward to hear from folks that were not on the trial but had a fix applied to their line too.

[#10]

No change here yet. 

[#11]

I've just put my Billion 8800NL back instead of the ECI modem to see what had been done to my line, and there is G.INP on the downstream but not on the upstream, screenshot of the DSL stats attached.

[#12]

@andy265 have you left the Billion on the line or switched back to the ECI, If working right The DSLAM should see that your using a Huawei based modem with the BIllion and such put G.INP back on the up stream It would be interesting to see if that indeed happens.
 

[#13]

I've left the billion to see what happens.

Quote from: InterZoom

Not sure why the downstream sync hasn't improved (see attachment with BT IP Profile - speed test is limited by PlusNet profile).

So here's an interesting one.
Things look to be back to normal in all but one respect: the BT IP Profile for my line is still showing as 65.74 Mbps.
A GEA test this afternoon shows the line to be in sync at 79.9 Mbps down and 20.0 Mbps up with the ECI modem / Huawei cabinet combination. (Obviously, the modem is locked so that can't be directly confirmed.)
The same test shows the DLM profile (timestamped 2015-05-15T14:15:00) as:
0.128M-67M Downstream, Retransmission High - 0.128M-20M Upstream, Retransmission High
Ping is still 6ms. (Happy with that!)
Maybe I've misunderstood the relationship between the DLM Profile, BT IP Profile and sync speed?
If the sync stays at the maximum (as it should, absent the line fault,) will the other two eventually catch up?... Or is something still amiss?...
Previously, the BT IP Profile immediately reflected the higher sync speed of the Huawei modem when using G.INP rather than having interleaving forced upon it...
So I suspect the latter. That is to say, that the solution Openreach has now rolled out is - still - not a complete solution.
I can't argue with the view that it doesn't ostensively impact my own service at the current time, since my PlusNet profile is capped at 40Mbps; but it would were I to decide to take maximum advantage of my now-returned-to-marvellous line performance by 'upgrading' to the 80 Mbps package.
And (if not a temporary blip particular to this line) it may have implications for those others who are on that faster package, are connected to a Huawei cabinet, and are expecting to be able to enjoy the benefits of 80 Mbps bandwidth despite having been supplied with an ECI modem...
As things stand, it looks as if that may not be technically possible.
Which means that some people are paying for a service which was advertised but which it is in fact no longer possible for the supplier to deliver. Unfortunately.
Maybe I'll hold off on that upgrade...
Unless I were to put the Huawei modem back on the line... I bet that would fix it!

So it's a some and some Situation then.
