Openreach enabled G.INP on FTTC

bulldog147 · 28 Mar 2015 at 10:32

It's now appear that Openreach has rolled out each days to enabled G.INP on FTTC. As We now seen there is no error on the line expect FEC.

Mine has been switched on G.INP this morning.

How to tell G.INP is operational on your line

It’s not exactly obvious when G.INP has been enabled, and statistics provided by your modem may be somewhat limited and confusing. There is much confusion about G.INP currently on Internet forums, with broadband users unsure whether their line is G.INP-enabled or not. What makes the situation worse is the fact that some modems may not currently support G.INP.

I can confirm that G.INP works with the following FTTC fibre broadband router modems:

Billion 8800NL
BT Home Hub 5
Netgear DGND3700v1 (not v2)
Openreach Modem Unlocked HG612

G.INP is Impulse noise protection

bulldog147 · 28 Mar 2015 at 17:56

I don't know as I don't have BT Home Hub 5. But maybe u should check here: https://community.bt.com/t5/BT-Infinity-Speed-Connection/BT-G-INP/td-p/1460086

bulldog147 · 29 Mar 2015 at 12:07

Some seeing increasing ping when G.INP was enabled, some don't have this affected. Mine doesn't affected at all.

bulldog147 · 29 Mar 2015 at 12:23

I know. I rather to have fastpath as mine is 80/20 no problem with fastpath for 13 months until yesterday morning openreach have enabled my line to G.INP Interleaving which it really quite annoying. But sadly once the G.INP was activated on the line, the fastpath are now no longer in use and DLM will not disabled G.INP.

Every FTTC lines will be getting G.INP anyway. Nothing that ISP's can do nor BT Wholesales can do. It's all down to Openreach!

did you get a ping increase?

Nope! My ping was 12ms before and after G.INP was enabled. The ping remain the same as 12ms. Thinkbroadband Quality Monitor graph did show the same ping after the line was resync itself with g.inp on it.

this is my ping test (london server) with g.inp fttc.

Well Ginp has just turned it's self on and now my ECI modem will not work on my line...

Good job I get rid of Openreach ECI Modem to get Billion 8800NL instead. As Billion 8800NL support G.INP, G.Fast and Vectoring for future say Billion tech support.

So to be on the safe side Zyxels 8324/8924 & 3300 plus the billion 8800 are known to work well with the new line settings g.inp.

G.INP on Billion found here: http://www.increasebroadbandspeed.co.uk/g.inp

my Billion 7800n doesn't let me see my fibre line stats

I have been considering a new VDSL router can anyone recommend something good?

Get a Billion 8800NL upgrade!

bulldog147 · 29 Mar 2015 at 18:28

The vectoring isn't planned yet by Openreach. As far as I know that Openreach is rolled out G.INP to all FTTC cabinets. (up to 45,000 lines per day)

1st stage: all G.INP enabled on all Haewei cabinets lasted until 31st March 2015
2nd stage: all G.INP enabled on all ECI cabinets from 1st April onwards until end of June 2015.
3rd stage: Openreach will try to get vectoring roll out possible in 2016 or 2017 depend on trial tests.

bulldog147 · 30 Mar 2015 at 16:30

^^ Spot on review! Well said. I am still happy overall with my billion 8800nl.

Meanwhile coming soon the new 8900 series for Fibre:

bulldog147 · 30 Mar 2015 at 22:05

Here is latest data sheet from BT Openreach for upcoming:

bulldog147 · 30 Mar 2015 at 22:12

^^ LOL. That's BT for us!

bulldog147 · 31 Mar 2015 at 16:51

Tomorrow is the last day of rolled out G.INP for all the remaining Huawei cabinets.

From 2nd April the rest of ECI cabinets are start to roll out G.INP and should completed by end of June.

bulldog147 · 31 Mar 2015 at 17:24

ECI modem on ECI cabinet will be automatically G.INP (usually overnight between 4am and 6am) during roll out. No one know yet if the G.INP will cause issues.

bulldog147 · 31 Mar 2015 at 18:08

Here is picture of what the cabinet are look like can be found here: http://www.robertos.me.uk./html/street_cabinets_etc.html

bulldog147 · 1 Apr 2015 at 11:42

mine is 11ms

bulldog147 · 2 Apr 2015 at 11:17

Locky. I agree with you on this about BT. I was so fuming angry because openreach just go ahead and roll out G.INP on every lines who has 79987/19999 for a very long time with fast path and very low ping until G.INP put on and ruined the line to reduced the sync rate and increase in ping is total disgrace!

BT Openreach just don't care about your problem's end. I was surprise that many Huawei cabinets are suppose to be given HG612 2B & B3 Modem not the ECI Modem.

bulldog147 · 2 Apr 2015 at 13:56

Last year I have a proper BT Openreach Engineer to installed FTTC on my line from ADSL2+ and he replaced a new MK2 master socket and he went back to his van and gave me ECI Modem as I say to him "Hold on, my cabinet is Huawei 288, should I have Huawei modem instead?" he reply "There is no difference between two modems as we don't sold Huawei modem anymore!".

But, when he left, I just use my own unlocked HG612 (I brought it off ebay for £20!)
