'DLM Quantisation' project, safe times to reboot?

[#1]

When is a safe time to reboot a router with the new 'DLM Quantisation' project so that we aren't given a new lower IP profile?  Bob Pullen informed us about it after on usenet after some have IP profiles that differ from the expected.
I decided to return to a newer firmware after tryng to get more stability with an older one and failed, so added the firmware 5am ish.  First reboot it auto connects with default settings so required a second.
Each reboot dropped the tested download speeds by about 30kB/s.  Used to be 4am onwards was safe but no longer so when?

Hey Gus,
It should make no difference as long as you tell the router to disconnect first rather than just power cycle it as that would get picked up as a forced disconnection.
Rebooting in the first few hours of daylight may give you the best chances but the improvement would probably be minimal.

This New Feature isn't working. Just lost sync twice, once with a fault second a forced re-sync.
First time my connection speed went From 2278 kbps download the normal 373 kbps upload, on reconnection it was 2000ish and 300
Second time 2559 kbps and 105.  On the forced re-sync why did my download jump back up to what it was a week ago but my upload dropped by 2/3's
Can you Not beta test on live accounts as that is exactly how it seems

From my strange BT Test results I assume my circuit is an experimental one. Despite some drops sync has been up to 9K with att 47, margin 3. Last night a storm did its worst and sync was down to 8147, margin 6.
Disconnected and powered down; went out shopping; rebooted router on return; sync 9059, margin 3.
All watered down of course by the reported profile system- 6500.
Hope the project succeeds, though there might be elfin safety issues that some suited gnome could be looking for, like terminal EU shock to scupper it.

What sections of Plusnet know which EUs' connections are on the trial, like tech support for instance?

[#6]

I suspect there isn't an EU associated trial as such - just BT testing new DLM/MSAN software for short periods in various exchanges as they see fit. In my case TBB download speeds increased by around 170Kbps (5050 to 5220Kbps) for a period of 48 hours, then dropped back. IP Profile 5500kbps throughout with increase to 6000kbps counting down the days. (I assume K=1024, k=1000.)
I've been on ADSL2+ only for 6 weeks, and the router re-syncs when the DLM software is changed - giving the appearance of a dropping connection. On maxDSL I'd been connected for 50 days prior to ADSL2+ upgrade; maximum duration on ADSL2+ has been about 5 days, giving the appearance of less stability. Installing/removing the trial DLM software perhaps gives a false impression of (reduced) stability on ADSL2+.

What does EU mean?
AFAIK 'DLM Quantisation' is a meaningless expression?
My line has been running on a 3dB noise margin, enhanced IP profile for weeks now.
Plusnet's profile settings do not operate in the same world though.

@ fox Bob P mentioned that description of it on the usenet after a few reported getting previously unknown IP profiles

Turns out that the non-standard IP profiles are part of BT Wholesale's 'DLM Quantisation' project. The idea is to set the profile kind of 'on the fly' like what happens with Fibre. It only affects certain 21CN provisioned circuits at present, and we're still ironing out a few matters with BT before we can announce anything.

You may well be on to something. My copper line was repaired recently and sync shot up and margin dropped well below standard target. A ticket was still open, so I enquired about drops and re-syncs with details. the line has since re-stabilised. Now for the next round of fun.
I'm in two minds now, whether to close my question on basis DLM Quant is the cause, or swap router and do yhe further tests suggested by support.
One lot of muddied waters, but rwo???

[#11]

So everytime i resync is goes down and it can't get back up ?
thats pretty retarded.

[#12]

I get quite a lot of re-syncs (several per day), however my noise margin is a fairly constant 3dB.
Sync speeds are considerably higher than they used to be.
This has been going on for several weeks.
If Plusnet would give me a profile that actually matches the BT speed tester IP profile, then I would have a faster line.
I don't have a problem with BT dropping my line every few hours.

[#13]

Can anyone point me to a link that gives "official" info on the DLM Quantisation project? Please!

[#14]

As far as I know - it is all unofficial and it was only Bob's post which told us it was even happening

[#15]

On here? I couldnot find it.
Linky?
