Retraction of G.INP :(

So I read a few rumours that G.INP is going to be disabled on upstream for all lines now!

That's both Huawei and ECI cabinets!

I don't think this is very good and is a great example of our providers making a boo boo and passing the ramification's on too the service users...

Why is it that ISP's and Openreach haven't been held responsible for any issues that have been caused during this "boo boo" after all it was their engineers/contractors and departments that sent/installed the wrong EU Equipment in the first place.

Meh. Very few people need it so it seems a reasonable solution to me.

Because they provide a service and by the standards of the industry they are doing a reasonable job which is all they are required to do. If you think you can roll-out FTTC (or indeed any other communications technology) across the UK and get it right for everyone first time then set up your own company and go into business.

Anyway upstream G.INP really isn't worth crying about. I think it's far better they concentrate their R&D efforts on the next gen upgrades than tweak a pretty minor feature of the current system.

A lot more people need it than would otherwise have been the case due to the use of contractors .

Also it's a poor compromise because the largest customer - BT Consumer - supplied the wrong sort of Homehub - HH5A's - to customers on Huawei cabinets.

So, it is needed because of bad installs but no-one can have it because of the uncontrolled issue of free Homehubs.

What's the contractor connection?

Poor installs (and supplying ECI modems and selling the Huaweis on Ebay)

If you suspect an ebay aeller is selling stolen goods then am sure BT security would like to know

I think the volume of Huawei HG612s for sale on Ebay over the last 4 years speaks for itself.

Handing out ECI modems to subscribers might well cause a contractor's van to become relatively top-heavy with HG612's.

However, that inventory doesn't suddenly get labelled as "spare", and free for a contractor to dispose of. He still has to do something fraudulent to be able to sell them.

I have to say that I disagree there.

Upstream problems have never been worse than downstream ones. DLM becomes involved considerably less on the upstream side.

And the *impact* of packet loss on upstream is felt even less: The main issue that BT wants to solve with G.INP (loss of packets that don't otherwise get retransmitted - particularly in video streaming) just doesn't happen upstream.

Don't get me totally wrong though ... a solution that kept G.INP bi-directional would be an improvement, as would deployment of capable hardware. It's just that turning G.INP off upstream isn't as terrible as you make it sound.

BTW. As far as I can see, the issue isn't as simple as hardware that doesn't support G.INP upstream. Some modems, using the same "limited" chipsets, have been "fixed" by firmware upgrade. If the issue remains long-term for some models, then something more subtle has gone wrong.

I have plenty of experience of capped upstream speeds following ham fisted installers visiting my cabinet, so don't try and tell me it doesn't happen. G.INP managed to fix that for a brief couple of months.
