Well, seeing as Openreach never authorised the use of kit other than their own, until they issued strict specifications for ISPs to supply theirs ....

See SIN 498.

It isn't the "official spare". It's the official kit.

Thanks. I've switched from the ECI modem to the HG612 3B running the latest firmware. I'm back on fast path, and upstream sync has increased by a couple of megabits, which is nice.

Not for long as you will be switched on G.INP next few days because G.INP (interleaving) replaced Fast Path.

Maybe BT will start to allow ISP's control in order to perform this remotely as no physical work at the cab is needed by engineers just a phone call to request it

Chris Pettitt (Plusnet staff) did metion this last year to me. But nothing is done. I doubt Openreach will allow this to ISP to remotely themselves.

That looks a bit garbled to me. G.INP largely eliminates interleaving, but may leave some interleaving and FEC correction in place.

So those of us using our "own " modems when G.INP was enabled now find that the supplied ECI modem (sitting on the shelf as the "official spare" ) is of no use as a backup !

Correct. It's now a doorstop if your line has G.inp enabled on it.

From recent posts, it does look as though a few of the VDSL2 routers people have bought are getting G.INP upgrades if they go hunting.

I've been warning about this sort of problem since people started buying the Fritz box (7390?), which IIRC was the first that was made to work.

Morning folks, sorry for more questions...

Other than on the install day, my ECI modem has been connected for almost 12 months now (I also have a HG612 from our previous house).

If G.INP has been enabled on our cabinet and I am still connected ok with the ECI modem with what appears to be interleave enabled (My latency has risen and my download speed has dropped) does it mean my ECI modem has been upgraded to accept G.INP?

If G.INP has been enabled, isn't it supposed to improve things and not make them worse?

Should I leave the ECI modem connected for a while longer (Been two weeks today) or try my HG612 and update its firmware to the 08 version?

It means your ECI modem has not been upgraded, but the cabinet has. There is a discussion in another thread about how to get the ECI upgraded, but I'm using an iPad in bed and finding it for you would be a pain that way.

I'd put the HG612 on, but see the seansmit17 thread I replied to a few minutes ago. That needs the latest update if you have an older one.

exactly the same has happened to me..there are alot of posts on the bt forum stating this,but most are getting fobbed off with"its crosstalk/line fault"etc even bt dont have a clue

Can someone just confirm the interleaving status on a g.inp enabled line.

I am now syncing at 79999/20000 and have g.inp enabled and also interleaving on the line - this appears to be affecting upload speeds. Will this come off after a few days/weeks or should interleaving be on all the time now.

Setup is a Huawei modem flashed -> BT Homehub 5
