I was told next year by a BT engineer recently, though I can't see my exchange listed anywhere. At 213m to the cabinet, I quite fancy the idea.

I still don't see my exchange.

Sebby · Jul 11, 2009, 19:05:04

I'm on it (Barnet).

Idnet informed me this morning that BT have now 'unbanded' me & that it was thus OK to reboot my router. And, of course, I've now snipped my orange ringer wire.
So ...stats now look very different. Are these figures healthier?

Speed however remains at 5MB - so no change there. Does the line go through another 10 day training period?

Thanks, Ron, we try hard to make it a good place to be.

Rik · Jul 13, 2009, 15:21:41

They are a lot better, you just need your profile to catch up now. Be patient, let things settle and you should be seeing a throughout around 16M.

Steve · Jul 13, 2009, 15:33:50

Does this now prove that BT have an additional mechanism of controlling sync rate on adsl2+ apart from solely by margin adjustment ,in this case the unbanding has allowed the sync rate to rise and the downstream margin to fall from 28 to 7.6

Rik · Jul 13, 2009, 15:38:21

The margin falls with the speed increase, Steve, but this banding/unbanding does appear to be new and I'm trying to get more information.

Steve · Jul 13, 2009, 15:46:22

It would be nice to know if this banding does exist.Previously with adsl max anyone on less than a full sync the maximum margin was I believe 15? I am guessing something can be placed on a line to prevent a resync gaining the appropriate increase to allow the stated margin to fall even to the previous maximum of 15, which I am assuming is still the case on adsl2+

Rik · Jul 13, 2009, 15:48:52

I'm hoping for more information soon, Steve.

Steve · Jul 13, 2009, 15:50:27

RonGodwin · Jul 13, 2009, 15:57:41

16M .... Yowza!!!!!

IDnet did seem to confirm that I had indeed been 'banded' - said they just had to get onto the 'backroom boys' at BT to fix it. From getting my email
reminding them this morning it took all of 10 mins!

Th said backroom boy had been in India until today.

At least I know I was telling the truth on Friday

Waiting to hear what the fudge is going on with my line at the moment, I am seeing big ES spikes of course with CRC errors to match but my connection is fine a stable 15DB Noise Margin but a paltry 3000kb sync rate where I was getting 3500 on ADSL1

Rik · Jul 13, 2009, 17:21:14

Sounds like banding is in play.

Simon · Jul 13, 2009, 17:23:11

Well, hopefully, IDNet won't let the bands play on.
