Andy,

I believe you are UK based, if so, then try http://www.adslguide.org.uk/
for more information.

If the connection is a standard 'basic' business ADSL package, then you
will have a 256Kbps upload, with a 20:1 contention ratio i.e. sharing
the 256Kbps with up to 19 other users. This is also rate adaptive, the
upload speed will vary with line length / quality between 100Kbps and
256Kbps. The expected increase in speed may not materialise.

There are various options; upgrade data rate / reduce contention ratio,
or if you are in London then look at SDSL. 

Regards,

Nick
