No, banding no longer removes itself on VDSL2.

Downstream seems reasonable in comparison with other lines with similar attenuation on MDWS

OK BB, you know me, I like to have a rough idea of the D-side length and be looking at the stats on my tester, and then it's more a matter of 'feel'. Maybe not the scientific approach others might eschew, but it seems to get me by in the main

You know the rules and you are not excused from the basic rule set

I know that, just trying to help.

That is incorrect. My line was banded for a long time - months - but it eventually removed itself.

It absolutely does.

What people don't get to see is that even if a line is stable on a banded profile it may still fall into DLM's amber category, which would mean DLM wouldn't release or relax the banding.

Thanks for that lee. It makes sense of the inconsistency we see given the limited information we can glean from many modems' stats.

I've had this router in place for >4 months now. I think you are being too charitable to BT/Openreach.

>4 months and a cap is a long while to wait. ES on the line is also very low.

I consider the cause to be BTs complacency rather than something the "magical" DLM is doing and that BT should demonstrate the reason for the cap' and possibly relatively low uplink sync' rate.

Which modem are you using? Ah yes I see it's a ZyXEL VMG8924-B10A. Have you tried another modem?

Indeed, stats raw stats aren't that helpful as DLM looks at every aspect of the line before it categorises (green amber red, which I'm sure you know).

Most of the posts on Kitz where banding has been relaxed is on lines that MDWS shows green consistently.

As far as I know, once on a banded profile, a line will never be on a fully open 0.128-80mbps unless a full DLM reset is actioned by an engineer.

I don't have a list of the banded profiles as they seem to have changed in the last few years. Sub 40meg bands have increased in number, so the banding isn't as restrictive as it used to be. Most bands lower down seem to be in 1-3meg increments.
