That's good.

It ties in exactly with what I was saying about those BT SIN quotes.

SIN 498, if memory serves.

Clearly PN have their timing set to too high a figure for the Openreach modem. The question is, have they got to have it like that for some other reason, or could they lower it?

I did ask the question many moons ago, but didn't get a response from Plusnet.
Being aware of it though, it doesn't really matter to me personally, but it may have been useful for others for it to actually work as intended.

Just as examples:-

"On the fly" - 16 seconds:-
2012-9-7 20:8:33 Notice 104500 DSL activate succeed
2012-9-7 20:8:17 Notice 104500 DSL deactivate


Reboot (also needing the MODEM's clock to be reset) - 25 seconds:-
2000-1-1 0:0:25 Notice 104500 DSL activate succeed
2000-1-1 0:0:18 Debug 104500 LAN1 up
2000-1-1 0:0:16 Debug 104500 LAN2 up
2000-1-1 0:0:16 Notice 1 System up
2000-1-1 0:0:3 Warning 10400 KLOB Pool 1 Initialized: 1048576 bytes <0x80300000 ... 0x80400000>
2012-9-8 14:1:7 Warning 104001 System reboot


EDIT:

I see the SIN was updated in July:-

Yes re the update. They added all the stuff about the requirements for wires only installation, so ISPs can start lining up end user equipment to replace the OR modem.

Plus they added the warning that the noise margin and sync rates should not be tampered with .

Just to nail this once and for all, I find that my modem has re-synced this morning at 65802 (down from 72203 after my longest ever period at the higher speed without interleaving - it will probably take over a month to increase again, if it ever does).

I have checked my BT IP profile (not Plusnet's) and it is still 69.89Mbps. Obviously the Plusnet profile is still 69.8 as it cannot have received a delta report for something that hasn't happened. I'm just going to leave it and see what happens, I won't be rebooting the router.

Speed tests show pings doubled (not surprisingly) and download speeds reduced by about 6Mbps. I hate Openreach's DLM!

(My) Theory says the IP Profile will correct within 24 hours.

The problem is either the WBC DLM or Plusnet not detecting the re-sync. The Openreach DLM has nothing to do with it if the re-sync is quicker than the CPs' settings detect - it's their problem for ignoring the tech docs they have, for whatever reason.

I imagine most people, certainly me, like the shortest time to sync as is possible.

My experience is that the IP Profile doesn't correct itself unless a new PPP session is initiated.

I tested it for a few days once over, just to prove the point that some (maybe all) ISPs aren't always aware of quick "on the fly" resyncs that indicate instability.

We wouldn't have a leg to stand on in arguing that a connection was unstable (needing repair work) if the HG612 was still unlockable.

Well, 24 hours later the IP profile has corrected itself to 63.69Mbps, so one point to Bob
The Plusnet profile, however, is still 69.8 and I expect that to take another 24 hours to change.

I thought recently one of the reps said they receive delta reports three times a day, but whether that is pushed to them for all changes, or pulled by them for those they are aware of having had session drops, I haven't a clue.

We receive delta reports whenever there is an PPP/sync disconenction/reconenction, and if there is a change in sync speed then your profile will be updated.

Not quite Chris. They should be *generated* each time there is a resync that changes the sync speed, however we only poll them a few times a day.

Well I'll let you know when mine catches up! Not a problem at the moment as it's higher than my sync speed.
