Just been clobbered by G.INP removal. From 70122 sync to 57395 sync interleaved. 

[g3uiss]

Seems not every line goes back to Fastpath. I was on fastpath before g.inp applied now interleaved for 3 days since removal. Others seem to get back to fastpsth after 2 days.

I lost G.INP as well about 8 hours ago   Insert favourite curse here ____

Good news is that I'm on fastpath by the looks of it and the drop is 'only' 70.998 Mb/s --> 67.684 Mb/s (so far).

Bad news is that the downstream FECS which have always been 0 with G.INP are now in the high thousands ... I hope that won't trigger interleaving and an even lower speed.

Story so far in case people might be interested:

- DSLAM/MSAN type: IFTN:0xb204 / v0xb204
- Before G.INP I used to have speeds in the region of 61.300 - 62.500 Mb/s for downstream, with downstream interleaving in the region of 700-1000 (for ECI/r modem). With an unlocked HG612, interleaving was previously in the region of 1200-1900 and speeds were similar.
- After G.INP was enabled I've been on 72.371 Mb/s with G.INP for about 14 days, on an OpenWRT ECI/r modem.
- I then did a resync to see what speed I'm getting with my unlocked HG612 and the result was highly disappointing, it synced at only just 66413 Mb/s with G.INP enabled.
- I went back to the ECI/r modem immediately and I have been on 70.998 Mb/s with G.INP ever since, for another 14 days that is...
- 8 hours ago G.INP was removed from my line and currently I'm on fastpath by the looks of it with a current speed of 67.684 Mb/s

DOH!

It was good while it lasted ... I hope BT get things sorted out soon and we don't have to wait months and years to get G.INP re-enabled on ECI cabs again ...

Perhaps we should rename this thread
"I have G.INP no longer!!" 

[Dave2150]

My line is still blessed with G.INP for now at least - hoping they forget about my cabinet!

[skyeci]

Wishfull thinking  your time will come

The Lord Giveth and The Lord Taketh Away.

[Chrysalis]

cathome, seems a new hybrid fast path mode where FEC is enabled without interleaving (same as upstream).

[S.Stephenson]

I still do 

For how long though 

[atkinsong]

Still active here as well.

Back to FastPath 

[shadow4dog]

I eventually got back to Fastpath but now slower sync than it was before G.INP started.

Before G.INP I was syncing at about 68Mb with an ip profile of about 65Mb ish and now syncing at 66Mb with an IP profile of 60Mb. Plusnet tell me I'll be able to leave the contract if it goes below 58Mb! My download is at about 56Mb over a wired connection. I think probably if I disconnected the line for 35 minutes I'd get the correct profile but I think I should let my ISP sort this out for me. The faults only been open for 6 days.

I lost G.INP 18 hours ago. Stuck on a higher ping now thanks to interleaved on the downstream . I wonder if ECI will ever get G.INP, as it was working fine on my line.

[skyeci]

I saw a drop in ds sync after g.inp was removed. I have tied various re-syncs just to see if the ds sync would go back up but it does not. The best I had on g.inp was 68mb for my line. Now sits on 62 with fast path.

Yes - I am in much the same boat.

TBH it makes little difference to me as we use the line for general web browsing and film streaming.

But it would be nice to have it back.
