Re: Still aint gonna compete with fios. Only one modem is permitted to send in a specific time slot on an upstream channel. Multiple upstream channels can be allocated. More importantly, however, is the fact that this restriction does not mean that only one modem can have a two-way session taking place at once. DOCSIS divides the channel on a time basis (like TDMA for cell phones... come on, you didn't really think they had one frequency for every digital cell phone on a tower, did you?) and this is more than enough to allow modems to send multiple packets per burst and have enough turns to go around for all the modems in the node. Go get your facts straight. |
