We are based in Somerset, looking at a minimum of 10Mb at the hub site probably 100mb.
The connection needs to be used to transfer A LOT of business critical data between two sites throughout the working day with a view of more remote sites coming on board at later dates
Have already spoken with BT and they were shocklingly expensive
I would also recommend each remote site having an SDSL backup if it is business critical. Try NTL Business as they are the most likely alternative operator to BT in Somerset.
NTL don't have any circuits in this area so the cost was outrageous, even the salesman at NTL so it was stupidly high
SDSL isn't available in this area, or at least it wasn't about 6 months ago
Not that rural, only about a mile from J26 of the M5 on a business park
