Max ADSL exchange enablement

I understand that BT have set tentative dates for the enablement of some
5000 exchanges for max adsl over the coming month. What is exactly involved?
It does seem extraordinary that this number of exchanges can be enabled over
approx 30 days taking into account the years it took to get adsl into those
same exchanges or is this just a simple switching exercise?

I don't know about the preparatory work, but the switch on is simply a
software exercise as the hardware is unchanged but the fixed speeds are
augmented by speeds controlled by a target signal:noise ratio.

Enabling the service is a simple change to the config files (and a reset?).
Upgrading the links from the DSLAM and the core to allow for the extra
traffic is more complicated but has probably been done over the last few
months.

Has Plusnet made any announcement about how customers will be notified when
exchanges are enabled?

Knowing PlusNet, you will probably have to tell them due to the fact that
they are not allowed to email their customers because they may be breaking
the Data Protection Act.
Well that is the excuse they used when they were asked why they had never
emailed their customers about the price decrease's. Some poor sods were
paying £8 a month more than they should have been paying without knowing it
for months.

What is their slogan?
Ah, that's it................Plusnet, where we lead, others follow.
I do believe that the people involved in the £51,000,000 robbery last week
must have heard about PlusNets efficiency at daylight robbery and had a go
at emulating them.

Would there be any likelihood of ending up at a LOWER speed with max ADSL?
Here my line stats on 1Mbit are 63db attenuation and 8dB signal/noise
which is rather marginal for 1Mbit although the connection has been rock
solid since I got it last May. Would max ADSL suddenly decide that 512K
was the highest my line would support? Or does it depend on what speed is
actually able to be negotiated across the line by the equipment at each end?

The latter - it rate adapts on a continual basis - so lower as well
as higher speeds are technically possible.

Not quite true as they have been fitting better/new monitoring
equipment onto their DSL racks over the last year or so. It used to
worry me when I walked into a MDF & see lots of red leds, it doesn't
anymore..

I should have put effectively unchanged really, there have been some
changes and of course some of the VPs back into the ATM network have
been upgraded or additional pipes have been added.

But as for the switch on, it is done in software although it will depend
on the ISPs offering services that use the Max capability.
