Openreach changed DLM to not activate G.INP upstream by default, and the HH5A received new firmware.

Which didn't fix the G.INP problem as can be seen here:

I think Openreach resolved the G.INP themselves, the firmware was fixes for other things i guess

1. Did you have upstream G.INP activated with the Billion?

I've checked back on my screen grabs of the Billion and it does look like G.INP was enabled.
The setting they call "INP (DMT symbol)" was set at 48.
"D (interleaver depth)" on downstream was 16.

So it looks like the ECI definitely caused G.INP to be removed. Now I'd just like to find out how to read the current firmware version on the ECI to see if that was the latest available version.

Why bother? You have the HG612.

There hasn't been a fw update to enable G.INP on ECI modems.

OK.
I thought I had read somewhere that ECI modems didnt initially work well with G.INP but that they got a patch to support downstream only but I must have picked that up incorrectly.

Seems like a great reason for Openreach to completely disable the UI/feedback from these modems so people cant tell what they are doing and directly compare their stats to other (more capable) hardware.

Yes, following your and others advice on a previous thread I made sure I got a model 3B and updated it to the B030SP08 firmware c/w the GUI.

Now happy that I can see whats happening with DSLStats and that I can log into it remotely (as I work remote from my FTTC connection).

There's a lot of conflicting opinions about G.INP on devices that don't have a Broadcom chipset, but no definitive evidence.

I am aware of someone who created some firmware for the ECI modem that supports G.INP but it's not official.

I remain appalled at the decision by ISPs to remove any useful stats, but thank goodness for Asbokid's initial brilliance in hacking the HG612 in the first place, and for Howlingwolf's later work on enabling G.INP on the hacked firmware.

Ta.

That's a standard DLM intervention of "low interleaving" for downstream, with 19% of your bandwidth allocated to FEC protection, and 8ms of interleaving in that one direction.

There are some bit-errors happening on the line, but they've all been caught and corrected by the presence of FEC; none of the errors have been uncorrectable so far ...so there is nothing (currently) causing DLM to stay intervened. If it stays like that, it should de-intervene in due course. I wouldn't expect any intermediate reductions - just a straight removal of FEC and interleaving.

Attainable speed will probably settle around 84Mbps when this happens.

In the meantime, it may be good to monitor the average rate of FEC's per day, so they can be compared with the eventual rate of ES's per day once DLM de-intervenes.

Wow, in less than 24 hours the Huawei has removed all the extra latency the ECI added and throughput is up around 7 to 8Mb too. Its shocking to think Openreach are happy to fit these sub-standard ECI modems on managed installs.

BQM shows a nice drop in latency ...

It's also shocking to see the fanbois roaming the forums claiming that ECI modems and HH5As support G.INP when all the available experience says that they don't. Presumably this is done at the behest of BT who refuse to admit they have fouled up.

An excellent result for you.
