Cable systems in the UK have a range between 5 and 30MHz, 5 and 40MHz, 5 and 55MHz and in some cases 5 and 65MHz for upload use. Not all of this band is going to be usable due to the much higher ingress present in the upstream path.
The download spectrum can be as much as (in some areas) 54MHz to 880MHz.
Just a minor point that isn't as apparent as the specifications on the google searches you're doing to get the cable info.
Seems a little asymettrical to me in any case.
NTL's 2xx series modems are DOCSIS 2 compatible, they just appear to be skipping it and going to 3 instead.
I'd quite like to see higher upstream speeds, and think there should be some room there to increase them. Making them symettrical to help with torrent ratios isn't really an incredible commercial enticement to spend the required cash though.
FYI ntl's upstreams aren't even 10Mbit line rate
Some Telewest areas with their magnificent 384kbps upstream on 10Mbit are however.
Moral of this story - upstream use is disproportionate to downstream use, another incentive to
not offer symettrical services.
BTW you forgot to mention that sustained uploading on Optimum Online tends to cause them to reduce your upload to 128kbps for a while or until you phone in. Doubt that they'd tolerate torrenting at full pelt.
