Just to clear this up for me (Please!)...

In my case the HG612 modem restores full speed with G.INP now enabled, to get the ECI back to full speed I would need a DLM reset or does the ECI not yet fully support G.INP which is why I see "interleave" like symptoms on my connection with it in use?
If a DLM reset was done with the HG612 connected would that leave my ECI modem without it's update?

Sorry...I am trying to keep up!

You are in the same position as me and no doubt thousands of others, G.inp is active on my circuit , i am currently using a unlocked HG612 with a slightly older fw version that also works with BT's Gimp ,lol so we all will need a dlm reset so that the eci modem can function properly again, so enabling it (In theory ) to download/upgrade it's FW , followed by dlm re enabling it's gimp if it so desires

I say in theory because there as far as i know 2 versions of the ECI modem, and someone on the BT community forums is claiming to of had a dlm reset ,but the modem failed to dl & upgrade its fw, and dlm just re enabled it's gimp so that customer is no better off, so it raises questions ?? maybe the older version is not G.inp compatible or the fw they are pushing isn't with that version of eci modem this is the type of issue that can arise from BT supplying locked modems

Firstly, thanks to all who have provided info on this thread - it has been a great help to me today. I've had Sky Fibre Pro since March 2013 & it has always been rock solid, with a downstream connection speed of 80000 & speed test results between 72mb - 75mb download.

Anyway, I went on holiday 2 weeks ago & put up with horrendous hotel WiFi, so was looking forward to returning to my normal broadband. Got back home this morning, ran a speed test (it is a daily addiction!) & noticed I could only achieve around 55mb max. Somewhat perplexed, I logged into the Sky Router & noticed that my Download Connection Speed had reduced to 67920, so phoned Sky, but got nowhere - they just got me to reset the modem & hub (which made no difference), then told me that my speed was still within range & that speed could be impacted by distance from exchange & cabinet...I did explain that the exchange/cabinet/house were still in the same place that they were before I went on holiday : )

It is only after finding this thread that I now know the cause of the speed drop. I have an ECI Openreach modem & Sky SR101 hub. The cabinet I am connected to is Huawai. I've been considering ordering a Sky SR102 hub for a while, mainly to reduce the clutter of broadband kit/cables (I have an Apple Airport Express in the mix too). Can anyone tell me if replace the ECI modem & SR101 with the 'all in one' SR102' will I get back the full download connection speed? Is the SR102 G.INP ready/compatible? If so, would changing to the SR102 alone be sufficient, or would Openreach need to manually reset my line?

i think TP link make a Gimp compatible modem as do fritzbox both have a similar lantiq chipset to the eci openreach modem and i know that the fritz at least is G.inp and G vector compatible so future proof, or you could go the other route and buy a VDSL modem router that has a Broadcom chipset such as one of the billion 8800 series modem /router one box solutions or a second hand huawei hg612 3b bt openreach modems from off e bay and flash with firmware that also unlocks it so you can see what is going on

Whats the difference between 2b and 3b hg612 modems?

I know the engineer can't access the FTTC cab.

I was just pointing out that the DSLAM in the fibre cab I'm connected to doesn't appear to respond to remote requests. When an OR engineer came and sorted out a fault on my line he tried several times to do a DLM reset remotely from the app on his phone but it didn't work. He also phoned wherever and requested a reset but didn't work either.

Someone else came out a few days later and did the reset at the fibre cab.

The 3Bs are the ones that were modified to reduce the failure rate from overheating. Prior to the 3B, and possibly even now but largely ignored, once the problem became very obvious a standing instruction was given to the engineers to wall-mount them to improve the air circulation.

Proving the point really. He expected it to work, and also the call to base to work. Simply an issue at your cab that neither did.

On 31/03/2015 my measured download dropped from 75 Mb/s to 63 Mb/s and the ping increased from 12 ms to 25ms, after 4 months of downlad speeds between 73 Mb/s and 75MB/s.. I had an ECI open reach modem connected to Talk Talk Super router (Huawei HG635).I used the ECI modem with the Super router because the download speed was slightly faster than just using the Super router as a modem router. I called talk talk technical support and I was told that my line sync rate was 67 Mb/s so my measured download speed is within acceptable limits. So I decided to make some changes. I switched off the modem & super router for a couple of hours and then reconnected the DSL cable directly to the Super Router. Now my sync speed is 80/20 slightly better than the original Super router sync speed of 77/20. My measured download speed is now consistent at 75.2 Mb/s and the ping is back to 12 ms. It's obvious G.INP has been enabled at my cabinet, it's a pity the talktalk technical support are clueless about this as well as some other technical issues. Here is a link to an article about the deployment of G.INP.

Same as myself and many more it seems, previously the ECI modem / Huawei cabinet combo gave slight better performance than the H/H combo but after G.INP is enabled the ECI is no longer the better of the two.

As someone mentioned previously, I wonder if it was originally the intention of OpenReach to supply a Huawei modem if on a Huawei cabinet and vice versa which would have probably prevented these issues but it instead turned to a "whatever was in the van" approach.
