My line had was banded at 67,000 then 60,000 kbps, even with a 10db noise margin, the 67mb banding was there for a year with a 7-8db noise margin, the 60mbps banding was about 5 months with a 9-11db noise margin.

It never got better, only worse with the next fault that caused the 60,000 banding in the first place.

IMO banding virtually never gets dropped without a DLM reset.

Ragarok and the other posters have a point , it sounds like the OP [AndyPandy] has a banded line and the DLM is going to take a while to sort it out , unless the DLM is reset by OR.
Maybe playing the waiting game might be the best.?

Unfortunately Zen have not been helpful. Whilst the guy did say he'd "go away and talk to people" about getting an OR visit, he eventually came back and said they wouldn't.

Hard to justify the extra money spent if the support is sliding.

It looks like I'm probably stuck with it, unless another fault occurs, and I'll be sure to raise it as a BB fault, not voice.

It's not slow, it's just frustrating to see that extra speeds there, that I used to have, being "wasted". Hopefully the pending changes to OR's business model will make them more responsive to the consumer.

Having to physically visit a cabinet to perform a software reset, to an internet connected device, is stupid however.

This sort of thing is the reason Openreach locked the modem so the stats aren't available.

What is involved in a DLM reset? Surely nothing that couldn't be achieved by the ISP in the first place, by pressing a few buttons. If it hard wired into a card, what century was the card built! i.e. travelling distances to reset something is '70s technology.

As it is, if DLM reduces the line for no real reason then it's a win win situation for OR (they aren't shifting so many bits) and the customer loses out. I certainly feel that way. Unfortunately having used the BT line test, it says my IP profile is 66.82Mb and Plusnet have me at 67.4Mb. Even though it will go quite above back towards what I used to get. recent speedtest - Speedtests before DLM reduced the line There's nothing wrong with the line, just a naff system that likes to restrict customers. I got told it would reset after 72 hours but still waiting after a week and a bit. Looks like I'll have to wait for whatever it was that reset it last time. Maybe I need to put a UPS on the modem!

The engineer calls a number to request a reset and it gets done remotely.

The suggestion an engineer needs to visit the cabinet wasn't entirely correct.

It is or certainly was for years Openreach policy that DLM resets are only carried out at the request of an engineer after being called out to, and supposedly fixing, a fault. For a long time he couldn't trigger it directly himself either. He had to call his control centre and request it, and sometimes they would refuse.

I seem to remember something has changed in this policy in the last few months, but can't recall what sorry. Possibly the ISP can now request it, or at least the underlying provider - BTW/Sky/TT/Voda.

Yuk!

We overlapped .

Are you overlooking that FTTC cabinets have Battery Back-up to cover something like 8 hours?

I have actually seen them in the local FTTC, Huawei 288, when a faulty battery was being replaced.

I don't monitor the Zen forum here, but the number of very similar unsatisfactory responses from them we see in the non-ISP forums on this site over the last couple of years or so ruled them straight out of consideration when I left Plusnet. I forked out for 100GB allowance on AAISP instead.

Zen rarely seem to put up any fight against OR or BTW when a retail customer has problems like yours. I assume they are different with (true) business ones.

Oh yes, a task most easily done ......
