Any news from PN ?
This is will sway me back from Be* to Plusnet FTTC if you get end user control.

[quote=http://revk.www.me.uk/2011/10/bt-listening-to-us.html]BT listening to us?!
Again actually calling them BT. I know, scary stuff 🙂
So what have BT done right?
BT have a DLM (Dynamic Line Management) which tries to fine tune the settings on each broadband line to ensure it remains working at a good speed on a long term basis. The settings can be adjusted in many ways, and they are a trade off. Some settings can make a line more reliable against certain interference but also make the latency higher. Some settings can make the line faster but less reliable. There are a lot of settings.
Now, the DLM, taking care of all of these settings automatically, sounds like a good idea. Unfortunately it has its limits. In some cases the DLM makes matters a lot worse than simply picking some settings and leaving them. It is also impossible to properly tell the DLM what the customer wants - some people want the highest speed, but they know that the line will go off line at high speed every night and don't care as they are asleep! Some people must have a line that is reliable and really do not mind if it is set to only 500K if it works all the time. These are extremes, but especially with reliability the DLM itself causes resyncs and changes in the name of keeping the service reliable! In some cases the line characteristics mean the DLM cycles through different settings over a period of several weeks - thinking it can do better and then finding it cannot over and over again.
BT introduced some changes a while ago that allow the DLM to be slowed down - told not to make changes as often, or even told not to make any more changes. The issue there is that you get stuck with whatever settings you now have.
Now, on BE lines we have no DLM at all. We have direct control of the settings and we let customers tinker as needed. Our customers, or our support staff, can sort lines out if they are a problem and leave the settings where they work well.
So BT have finally listened to us and soon (December I think) we will have the controls to actually make changes to the settings and turn off the DLM on lines. We aim to expose the settings on the control pages so that customers can also make changes.
In most cases the DLM will do fine, and this won't affect most people - but those with iffy lines or special requirements will find this invaluable as a way to get their line working the way they want it.
So, well done BT for listening - I know it has taken a long time but looks like we may finally have something we have been asking for.
Now, can we have cheaper bandwidth please 🙂

If it is, please set my line to always use 9dB SNR and we are happy.

Quote from: ispreview A reader asked for clarification on whether or not the change will only affect 'up to' 24Mbps ADSL2+ (21CN) lines. AAISP have informed us that, sadly, it looks like it will. In other words those who can currently only get the slower 'up to' 8Mbps ADSL (20CN) service will not benefit.

Then they will muck about with it - and when it no longer works properely moan about the system being c**p.
I'd suggest that the ISP's only give control after the customer has had to confirm some sort "admission clause" they they muck about with it at their own risk.

Quote from: x47c From my cynical point of view it could make things even worse if you let some of the more lunatic and halfwit end users get control of something they don't understand.
Works well on Be*
Maybe end user control could be part of the Extra package or Pro addon. Value customers can request service profile changes via tickets or calling CSC.
That way its a monetised service for the bean counters

I'd set it so my 'PRO' gaming is configured for browsing UK servers, and not French/arab world or anywhere else other than the UK

Yes, we can confirm this will be available to us, but as for passing on control to the end user we don't have any plans for this at the moment. This would also involve development work which we don't have time scheduled for.

Will a profile request change work via tickets/calling CSC? Just like the DML opt out ?
The 3db fastpath profile will be a popular request
Shame their no plans to offer end user control. It might create more work for CSC ?
Some users may only want a gaming profile for a limited time, then switch back to a streaming profile say ( 6db Inp2) for the iplayer ect.
Thanks f9o

It won't be something that a customer can request. We're going to use this as an extra tool in our faults process, so when a faults agent feels that a customer can benefit from one of the profiles it will be much easier for us to apply.

The hard fix profile worked far better on the huawei msan I had trouble with.
I've got a relative, think of joining PN and this kind of info should help sway them your way, if they can opt for a hard fixed profile on 21cn.
Thx

I can't see this happening any time in the near future.

Another long waiting again! First 88.2% in Oct, next delta correct by BT in Dec and now no plusnet control panel until few years but if other isp's can do that to customers, then why can't PN do the same ?
