Has Openreach given up on enabling G.INP for FTTC, on lines connected to ECI cabinets?

My line (ECI cabinet) is fairly error prone, and now syncs at ~49mbps Downstream, which has reduced a bit over the years (presumably as more people in my street have switched to FTTC). My area is not due to be upgraded to FTTP (via Openreach) until 2026.

So, having G.INP enabled on the line would at least allow me to make the most of the connection.

Any news / ideas G.INP? I haven't anything from Openreach for quite a while about this.

Another question, would enabling G.INP on the line even prevent most of the errors from occuring / causing issues, assuming that Openreach could get G.INP (on ECI cabinets) working well on a line's Downstream and Upstream?

They've had a few more trials over the years to try get it working but I don't think it's going to happen.

G.INP helps with noise and interference so it should end up with less errors for your line.

What is your current modem? I'm on an ECI cabinet as well and swapping to a Vigor 130 modem helped with speed and stability by a tiny bit.
 
Can I just request that my ISP change my Noise Margin / SNR line profile to 9DB instead of 6DB, to reduce line errors?

Dont think isp's have any ability to set snr on fttc, you wanting to do this to reduce interleaving on you line? Some modem/routers can set an explicit data rate that you connect at, lowering your sync to increase snr
 
I just ordered a cheap Asus DSL-N16 Router / Modem, wish me luck (it allows the SNR to be adjusted using the web interface).

Won’t work because the SNR adjustment will be ignored by the DSLAM.

Can anyone confirm if SNR adjustment via a router works or not on FTTC? Or, has Openreach locked it down on the DSLAMs?

Why would that do that for those that want to make their connection more stable (and use less bandwidth)?
 
@Dg834man Thanks, good to know. I may try it at 4DB, as my current router has occasionally syned at 3DB, only for it to recieve more errors and reset to 6DB.

I'll probably end up running at 9DB though, for max reliability.

EDIT - My current router synced at 3DB today, giving me approx. 10mbps speed boost, although don't know if that will actually translate into a higher download speed.

The 'errored seconds' are already higher than at 6DB:
Upstream ES - 74
Downstream ES - 65

The connection doesn't seem to be able to handle 3DB anyway, presumably the errors are too high and it just switches back to 6DB if the connection is resynced.

Gonna try the new router now.
 
If you have a dodgy line then I can't see how putting an Asus DSL modem on the end of it will help, I thought they were pretty universally regarded as terrible.
 
It's actually pretty good, the firmware / web interface is the most extensive that I've used. Setting the SNR Margin works too, you can even see the SNR Margin of each different VDSL frequency in real time. Only cost me £10

Edit - I also learnt that the SNR margin setting isn't applied properly (stays around 6db) on the line's upstream, unless the line has UPBO disabled.
