G.Inp Implementation on Huawei FTTC Cabinets

Anyone any idea why it appears that G.Inp is not currently being applied to a lot of compatable BT Huawei DSLAM lines (various ISP's) and some existing users are actually having existing G.Inp disabled ?
I am aware that there are ongoing software compatability issues with BT ECI FTTC cabinets, I am refering only to Huawei cabinets and users with G.Inp compatable modems/routers.

I am also aware that there is a school of thought that G.Inp will only be applied to lines that are deemed to have a requirement and another belief that it is applied to all lines with a compatable modem/router attached, excepting the current ECI cabinets issue, the BT chief technical engineer appeared to contradict this belief, see kitz forum Q&A posting.

I am ADSL2+ to VDSL2 converted for 7 weeks now, fully G.Inp hardware & software compatable and on a Huawei DSLAM, still awaiting G.Inp application.

See MyDSLWebStats site where guite a few members on Huawei cabs. have relatively recently been G.Inp disabled and quite a few more are in the same position as myself ie. fully compatable but never had G.Inp applied.

I have not as yet taken this up officially with my ISP other than posting a few queries on their forum which were all ignored, feel it would likely be a complete waste of time anyway as nobody really seems to know what's currently going on with G.Inp..

I see 10 Huawei users having G.Inp recently removed and 5 never having had it enabled, out of 200-odd.

It's merely a tool that DLM has to use if it feels the line needs it.

It does not mean that every single line on a Huawei cabinet will have G.INP turned on.

Tiffy can you point to where on Kitz this is being discussed?

See kitz site here http://www.kitz.co.uk/adsl/ginp-retransmission.htm
OK, this was 2 years ago but has certainly never been contradicted or updated on kitz site as far as I can see.
Has BT changed it's DLM policy on G.Inp application since 2015 ?

Surely every VDSL2 line would benefit from G.Inp action especially with respect to DS ES rate, anyone who has access to MDWS have a look at the historic data of anyone who has had G.Inp applied, the before and after effect on DS ES rate is remarkable, better than interleaving with not as many of the associated overheads such as increase in latency.

Yes, I agree on the number of MDWS active users on Huawei cab's (10) which have recently lost G.Inp, examine their current stat's., most are now on quite severe depth DS interleaving, why is this being applied when G.Inp was doing a better job with less overheads ?

How do you work that one out Batboy. MDWS doesn't always display inactive G.INP accounts. Once G.INP has been applied it needs to manually be reset by Tony eg on house move.

By looking at "All User Stats" on MDWS with View Active Only set to Yes, sorted on DSLAM.

I can't find that option but I am only using the basic version. My point is how does one know if G,INP is active or not or just disabled for Huwei cabs?

You can see that using the colour coded key at the top - green, yellow, brown and blank.

All User Stats is the last link bottom right hand side

Not available on Basic Version, just asked Tony.

IIRC it's one-off donation to running costs Tim. I found it well worth it.

I would certainly second that, MDWS is a fantastic facility well worth the £10 min, one of subscription requested for enhanced membership, Tony does a marvellous job of running and maintaining the site and certainly deserves the support.

Modem/router stat's monitoring is best effective on MDWS if kept running 24/7, a lot of the members, myself included, use a Raspberry Pi to run DSLStats harvesting the modem/router stat's to MDWS, I use an old Mk.1 B RPi which I bought years ago and never got around to using, works very well with DSLStats.

I have recently tried one of the new Raspberry Pi Zero W units which is very small, very cheap and very low power consumption running DSLStats, this also works fine and is a very low cost option.

Further to my original post yesterday and ironically enough, DLM has enabled DS G.Inp on my line @ approx. 06:15 hrs. this morning, that's one day over 7 weeks since my ADSL/VDSL migration.

Ref. G.Inp only being applied to lines that are having stability issues:
My line was running yesterday at the very bottom end of ILQ amber status, has been at the top end of ILQ green for quite a few previous days with respect to DS ES rate, I don't believe that DLM intervention was imminent with respect to current line status and DLM instigated a re-synch in order to apply DS G.Inp by default.

From the re-synch I have gained over 2 Mbps. increase in DS synch speed, a decrease in DS SNRM of approx. 1dB, and my DS ES's have virtually disappeared.

Any interested parties can view the before & after effects of DS G.Inp application on MDWS, ID tiffy.

A number of us on PlusNet with Asus DSL-AC68U routers reported losing G.INP around Easter time - thread is here:

https://community.plus.net/t5/Fibre-Broadband/Speed-...

Worst modem chipset I've ever used (The Asus DSL-AC68U).
It should be banned just for having the ability to toggle UPBO.
Asus appear to have given up on getting MediaTek to fix their DSL driver.

Have you tried another G.INP capable modem? Wouldn't surprise me if OpenReach removed it from the list of modems compatible with retransmission. It had so many issues during the initial Huawei rollout.
No idea if they ever fixed the ECI G.INP problems they had either

If G.INP has ever been enabled on a line then it will show as disabled if it's turned off (there is just an on/off flag in the uploaded data) but MDWS keeps track of the state independently. If it's never been turned on then it doesn't show at all. The only time it needs resetting is, if as said, you move house or change the cab etc.
