downgrading my ADSL

I have Sky's 20MBit/s package and am getting about 15MBit/s download
speeds from it. I'm quite happy with this, but got to thinking ....
KNow that I know my link will support > 10MBit/s, if I doengraded
to Sky's 10MBit/s package, there is no technical reason why I shouldn't
get the full 10MBit/s out of the circuit - is there?
Somehow I feel that if I did, they'd find a way to still give me only
a fraction of what the circuit can provide, even though it's demonstrably
capable of running at the full speed.

Anyone tried this?

It depends on how they implement it. If your line syncs high enough that
you can get 15Mbps throughput, they could contrive to limit the sync
speed of your line to about 11.5Mbps, then you'd get about 10Mbps
throughput. Or they could leave the sync alone and limit your IP
throughput to 10Mbps. Or they could limit your sync speed to 10Mbps and
you'd get 8.5Mbps IP throughput. Does my speculation look big in this?

Well, my presumption is that the max. line rate is determined by the noise
margin. My line obviously has a low enough noise floor to support 20MBit/s
and a 10MBit/s circuit would be able to operate with a higher SNR.
From Sky's website, my line was rated at suporting 16.6MBit/s during
it's "calibration" time (the first 10 days of my contracted connection).
So I can't see any technical reaasons why I shouldn't get the full
10MBit/s. Though somehow I have been conditioned into expecting that
no-one ever gets what they pay for with ADSL.

This may interest you from:
http://www.broadbandwatchdog.co.uk/s...grade-to-20mb/

Sky is to offer all it's Sky broadband customers a free broadband speed
upgrade to 20Mb from 1st June.
The move will also co-incide with Sky streamlining it's broadband offers to
just 2 options, either the Everyday Lite which is free to Sky TV customers
who also have Sky Talk, or £5 if it is a customer who only takes the
broadband but is capped at 2GB of data transfer per month or the Unlimited
plan which costs an extra £7.50 per month but does not have any restrictions
in place and is supposedly fully unlimited with no traffic management or
fair use policy's.

The 20Mb broadband will be using ADSL2+ technology and like with current
standard ADSL the broadband speed you actually receive will depend on your
distance from the telephone exchange and the quality of the line.

Both the broadband deals are available on a 12 month contract.

New subscribers online can currently also receive a free £25 M&S voucher of
they sign up to a Sky TV package online at www.sky.com.

Yes, I got the letter the other day. What te announcements somehow forgot to
mention is that Sky require you to sign up for a _new_ 12 month contract. So
if you want out during that period, too bad.

Yes when I was with Tesco I considerd a speed change and they were same a
new contract required, not fair if it not work out and you wish to go back
as you were.
I now choose ISPs with short contracts, 3 moths with Be that I have now.
But one as to pay more per month. Most ISPs seem to have 12 month contracts
and some 18 months, but really annoying that new ones needed on a change of
package.

It's fair enough if they bung you a new router/wifi when you join up. However
the Sky deal ties you in to their phone package, too. If you have a 12 month
BB contract, you have to take their phone contract too. So if you want to
change phone supplier, you can't without changing BB as well.

No although a new Tesco customer would get a new wireless router this would
not have been supplied to me and I would have to continue to use my own.
