Re: 3web - Sick of "unlimited download" claims yet
said by Sean  :Obviously both a DSLAM and a HFC node have available bandwidth link bottlenecks (though they aren't really, since often times theres enough bandwidth there), but AFAIK a HFC node has that extra bottleneck put in by the DOCSIS standard, that a DSLAM doesn't have. Yes, DSLAM has this same bottleneck: the max capacity of the cards used PLUS distance limitations...

said by Corvus :said by Sean :there's no "bandwidth" bottleneck at a DSLAM. Provided there's enough bandwidth on the main network, every user at a DSLAM can download full throttle. There is a bottleneck possible on DSL and it's at the DSLAM: Available bandwidth is limited by the capacity of installed fiber links. It's the same for a HFC node: available bandwidth is limited by the capacity of installed fiber. That's true; but as far as I know, a HFC node has it's own bandwidth bottleneck regardless of the available fibre links, as is set by the DOCSIS standard it's using. Isn't that true?
