Vectoring

I believe vectoring is an integral part of G.Fast, but for the last few weeks I have seen many posts implying or suggesting it can be set by G.INP or their router on the standard VDSL2, particularly on Huawei cabinets, but no contradictions when these posts appear.

This post by Andrew implies it is available universally on Huawei cabinets. I thought it was only when G.Fast was also present, and on some BDUK installations.

However, if some user modems do not have it enabled, (the default?), surely the vectoring will be screwed for those where it is enabled.

G.fast vectoring has nothing to do with vectoring on VDSL2

Different hardware, different parts of the radio spectrum

AFAIK vectoring on standard FTTC cabs was only done on a trial basis but it was never rolled out to all Huawei cabs. I don�t think it�s gone beyond the trial phase, ie mass rollout.

Vectoring was also rolled out to BDUK funded Huawei cabs. I happen to be connected to one and can confirm that my modem shows that vectoring is active.

A Huawei VDSL2 cabinet without Vectoring would not suddenly have Vectoring if a G.Fast pod was added to the PCP.

VDSL2 Vectoring and G.Fast Vectoring are completely independent and 1 isn't required for the other.

I've never come across a VDSL2 modem that lets me disable Vectoring, though their existence would not surprise me.

There are many VDSL2 modems (including some very large ISP's CPE) that simply don't support Vectoring.

There should not be any G.Fast modems that don't support Vectoring and 1 would hope there are none that allow it to be disabled.

edit: auto correct mistakes.

Vectoring was also rolled out to some, targeted BDUK funded Huawei cabs.

I added the bit in bold to avoid any confusion from your post.

Really? Any screenshot

I did think that, but was unsure. But it doesn�t answer the question .

The default should be that it's enabled - it's harmless having it enabled if not supported by the VTU-O / XTU-C.

Vectoring doesn't work as well but isn't 'screwed'. The options, depending on the operator and rules about attaching devices, are to just remove those devices from the vectored group and deal with it or, if devices must be complaint, shut their ports down until compliant devices are attached.

They're easy enough for an operator to spot. In their LR-VDSL trials Openreach just removed them from the vectored group.

We covered this extensively on the Kitz forum. You must've seen those?

Where it brought lines into the superfast range to achieve coverage targets vectoring was sometimes enabled. There are a few people who've noted it's enabled on there.
