Yes, but as the downstream rate is banded, then there has to be an underlying issue somewhere.

I wouldn't say isn't common. Automatic banding removal is becoming rarer. So, that's why I was quick to book a broadband boost engineer after my telephony fault was fixed.

And gained 133kbps.

Atm yes, but you watch, it'll increase. Are you aware of G.INP on VDSL? It's currently not active on my line because of the DLM reset. My line was syncing at nearly 48000/8700 Kbps before the issue.

And if the line fault has been fixed, DLM would lift the band and apply G.INP if it deemed necessary.

Yes, but I needed a DLM reset anyway, because on my line particularly, banding doesn't remove itself automatically. What you've said should happen, but it doesn't on a lot of lines.

Usually because they fall into the amber category due to errors.

Understood.

In reply to a post by RobertoS:

As you say, it looks like banding, but a boost engineer doesn't look appropriate to me at this stage, given the interleaving depth of 16 on G.INP rather than the default 8. I'd like to see those error stats after a while to see what is upsetting DLM. Both sets were taken very soon after reboots of the modem.

These are the stats since I posted the initial stat's in the thread.

What do you people make of the latest (4 days) worth of statistics shown above?

Tbh, I can't see much wrong there, 0 errors on the downstream and normal amounts of errors on the upstream. Whatever caused DLM to intervene was harsh but brief. Let's hope DLM removes the banding. If it doesn't within a month, then try and book a broadband boost engineer.
