said by Packeteers:said by motorola870:since Turbo went to 20/2 which now requires a DOCSIS 3.0 modem
this is total fiction - even 30/5 could comfortably be supported using a DOCSIS
2 modem, as each individual down/up channel has the theoretical capacity of 43/31Mbps.
and especially now that TWC is leasing modems, they have no incentive to give you equipment with a retail price 18 lease payments more than you actually need (on some very remote chance you'll pay more to upgrade your speed if and when it becomes available in your area). i live in an area with 50/5 support and was still given a $20 DOCSIS 2 ubee modem for 15/1 standard service. only because some invested their own money in DOCSIS 3 modems to avoid the lease fees, that you see them used while still on 15/1 or 20/2 plans.
TWC has stated on their website that DOCSIS 3.0 modems are the only ones they recommend for turbo and above:

www.timewarnercable.com/ ··· dem.htmlno 30 down on single DOCSIS channel is not even realistic you are sharing the channel and if you download at the 30Mbps really a maximum of 32Mbps thanks to over provisioning a single channel only has a net payload of 38.8Mbps and can only handle 1 extreme connection at once if it was used for extreme. Also DOCSIS 2.0 modems supposedly are not that good at handling QAM64 upstreams in the field so that it is recommended that you have a DOCSIS 3.0 modem for QAM64 upstreams. Most areas are transitioning to QAM64 also why would anyone want a DOCSIS 2.0 modem anymore they are outdated the SB5101 has been out for at least 7 years the technology is out of date and as TWC slowly upgrades their speed tiers to faster speeds such as the Kansas city turbo at 30/5 DOCSIS 2 modems are going to become useless and eventually the very bottom tier will need a DOCSIS 3.0 modem but that is several years off and that won't be needed until we have 16 downstream bonding or 32 downstream bonding which is coming in the next few years.
