You'd be surprised how well this actually works, just to remind services will be capped, which helps, could easily enough be traffic shaped to protect real time services, and I've seen services working quite well with over 200 modems on a 256QAM downstream, as high as 1000 infact, these modems mostly being 5.5Mbps/640kbps and 10Mbps/1Mbps.
Usage patterns do vary though, some cards have 200 modems on them and average less than 4Mbps downstream throughput, others get nearly maxed on the same number of modems now.
The joys of capacity planning, capping the 10Mbps will help a lot though, TW will get slaughtered in student areas especially, such as for example Leicester with De Montford, etc in that area
If it's any comfort to you a load of new kit has gone into Leicester, it's now one of the best provisioned areas for bandwidth per modem on the network if not the best, and more to come, so relax!

I have the ntl250 cable modem will this run at speeds of 10mb?

Easily.

Also the good thing about 10mbit is if someone asks you what speed is your internet you can casually say "10mbit", what about you?  |
DOCSIS uses 6MHz wide channels yielding potential throughput of 27Mbps or 38Mbps depending on how dense the modulation used is.
EuroDOCSIS uses 8MHz wide channels yielding 38Mbps or 51Mbps depending on the modulation density.
So EuroDOCSIS is the better of the two from the downstream point of view, however with increasing upstream demands its' inate higher asymettry can be 'an issue'.
EuroDOCSIS is the daddy though, especially EuroDOCSIS 2, which is happily powering the UPC 24Mbps/8Mbps service in Sweden
