G.INP affecting certain eci modems,resulting in a drop in sync rate and other issues

anybody else see a drop in sync rate/max speed? this is only affecting huawei cabs that have just been G.INP enabled and with certain eci modems.there are a lot of other instances of the exact same thing on other isp fibre boards where the user has lost around 7-10mbps sync speed,and had dlm kick in..but most are being fobbed off with the usual crosstalk etc..cheers karl

 

 

p.s most users with the correct/compatable modem experienced an increase in sync speed and also lower ping,so its good when it works 🙂

How do you know if your cab has just been G.INP enabled?

Re: G.INP affecting certain eci modems,resulting in a drop in sync rate and other issues

I have a HH5 and my sync speed has dropped, my noise margin has risen and my max speed has risen too. Looks like DLM has capped my speed due to some recent line noise.

Re: G.INP affecting certain eci modems,resulting in a drop in sync rate and other issues

Yes it usually happens when Kellys have been messing about in the cab.
I just wondered if there was any way to tell if the cab has been upgraded with G.INP

"p.s most users with the correct/compatable modem experienced an increase in sync speed and also lower ping,so its good when it works "

 

That does seem the case look over at Kitz with the modems/routers woking well with this transmisson settings. The zyxel 8324/ 8924 &  billion 8800 are displaying some impressive stats over there:)

 

The problem with the eci 's seem to be with new normal ones that are trying to be used on a tranmission line. My unlocked eci/r is has all the transmission settings enabled but I don't think you can do that with normal eci/r.

 

So to be on the safe side - it might be wise to steer clear of normal eci/r and certain tplinks & asus's  untill the niggles are ironed out. ?

Re: G.INP affecting certain eci modems,resulting in a drop in sync rate and other issues

quote from another forum who had an engineer out to solve this very same problem

 

 

"The BT eng has been out and he already knew about the issue with G.INP and ECI modems and showed me on the internal documentation on his laptop on how to go about fixing it.

They have to come out and perform a line reset which in turn allows the modem to perform an update. My profile reset didn't go to plan as it was being a pain. He had to call someone up at the HQ to force the reset manually, took it a while to stick but I'm back at low ping and full sync on the ECI modem, I don't think the line is running G.INP yet as he said the update to the modem does not happen straight away and takes place over a period of time (late at night)

Mine was the first the engineer has come across and his whole job sheet today is to fix this issue, so it's quite wide spread and BT know about it."

 

so get to it openreach!

Re: G.INP affecting certain eci modems,resulting in a drop in sync rate and other issues

can a mod issue a request for a line reset? or will it need an engineer to attend the cab?
