You always have to remember that a UK ADSL line has a contention ratio of 20:1 if you have business ADSL or 50:1 if you have the consumer option.


This means that in the worst event you could find out that your 256K on a business line is actually 12Kbit/s and the consumer option is only around 1Kbit/s. These are worst case scenario, but it would mean event one GSM call was too big to get down the pipe. In reality I suspect you would probably never see more than 4-5 people competing with you, but even then it is only around 50-64Kbit/s. I often find I get pretty much the full pipe, but you can't really plan on that and it would be bad to run too many calls over the line at a time. Typically we find that 5 is about the reasonable limit.
