I don't always agree with RobertoS but in this case he is correct

Openreach are in charge of DLM for the VDSL2 services as they own and run the active VDSL hardware, providers such as TalkTalk, BT Wholesale and Sky are given three DLM optoins they can pick from, but beyond that Openreach is in control.

For ADSL/ADSL2+ services from BT Wholesale then obviously BT Wholesale is in charge, and exposes more options to providers such as Plusnet.

The reason Plusnet talk about BT Wholesale supplying details of the FTTC service is because Plusnet buy the FTTC service from BT Wholesale rather than direct from Openreach.

That page is also out of date in a number of areas.

I know it's out of date, but I was showing the difference between the level of information shown and not the content.

And your point is?

That site gives lots of ADSL2+ info and fails with FTTC in a few places. How does relate to who controls the DLM debate?

You have said RobertoS was giving wrong information, if you were to furnish him with documents explaining what was wrong I am sure he would read, digest and fix any problems.

Even though it's on the Openreach network, Openreach still have to go through BT Wholesale in order to reset the DLM, therefore BT Wholesale control it. That is what I have been told by senior management in BT Operate.

So what you have been told contradicts documentation that the BT Group is required by Ofcom to publish? i.e. the various SIN/STIN document sytems?

The FTTC cabinets are owned by Openreach, Openreach defines how they should operate.

Who openreach subcontract to sit at a monitoring desk is a different matter, and this like the installation of FTTC may be a Kelly engineer or another company or an Openreach one. So Openreach may have some contracts with BT Wholesale for site interlink capacity to let them remotely admin their own hardware.

Power control is more sensitive with VDSL2 due to the crosstalk issues

In the days when baseband SDSL was slightly more common, there was the odd issue with someone running their hardware outside the ANFP rules as they could do so.

It's possible there is confusion there.

I'd be surprised if that is correct, but what is certainly true is what MrSaffron has said, Plusnet and any other ISP other than Sky and Talk buy FTTC from BT Wholesale. So if the ISP wants a DLM reset it is BT Wholesale they have to go through, and BT Wholesale then request it from Openreach.

No wonder your knowledge is very limited.

If you look at this website then see the difference to what level of information you provide: http://www.plus.net/support/broadband/speed_guide/br...

Sorry, I didn't see this link earlier as you edited it in whilst I was doing something else.

As has been said, that page is quite badly out of date. For example:-

7. Blip Logic

20CN products only

Some customers have very stable lines, but for one reason or another can occasionally see a one-off sync rate at a lower speed. The use of 'Blip logic' means if a stable line, (one that hasn't seen a IP profile decrease in the last 14 days), experiences a short drop in sync rate and then goes straight back up again, it won't result in a wait for the IP profile to catch up, although a second drop would lower the IP profile.

ceased to be true when the 3-day wait for IP Profile updates was changed. The Blip Logic code was dropped.

My statement on my website about this arises directly from a Plusnet rep who was asked on these forums at the time. Sadly I have no link to that post and it has been archived.

Well this guy may (or may not) be "Ratty" from the BT Care forums, but you have to admit the posting style, the odd dig (about Bob's website being "not so good") and the ridiculous insults "If you are unable to understand English I am sure I can refer you to some very good English lessons" are very similar the the posts by this "Ratty" person. As is the tendency to discount and rubbish other people's posts (claims & facts, etc.) without ever posting links or documents supporting the "Ratty" point of view.

The next plan of attack (by "Ratty") would be to move away from his claims (as he never substantiates them) and move on to picking holes in the punctuation, spelling and grammar of the posts he's trying to rubbish.
We shall see which direction this thread takes
