Maximum theoretical downstream on BY 10MB

[caffine]

Would i be right in saying that this would be 1.25mb/s ?

someone please correct me if i'm wrong thanks.

It's not quite that simple.

The maximum theoretical download speed possible at a downstream speed of 10Mbps (= 10,000Kbps = 10,000,000bps) is:
10000000 / 1024 * 1460 / 1518 * 1 / 8 = 1174 KB/sec, or just over 1 megabyte per second.

I know I'm being pedantic here but when blueyonder were testing 10Mb the actual connection speed was 10,240,000bps not 10,000,000bps. This would make the maximum theoretical download speed 1,202KB/s.

This is true. We don't know yet whether the 10Mb Telewest and ntl use will be 10,000,000bps or 10,240,000bps - or something inbetween. A 10Mb Ethernet connection is 10,000,000bps though...
