If you guys think you're going to get 10mb/s upload sustained...you're going to be sadly mistaken
. You might get bursts of it but I hope I'm mistaken. It seems very sketchy given the spec and currently with 2 channel bonding I just can't see them going to 10 on a consistent basis...3 or 5 maybe...but not 10...
...While the OP indicates there is room for 11 upstream channels, this is further from the truth. We'd all like to think that 5-42mhz is available for Cable services, but sadly it is not.
We have this little thing called Video on Demand...you wonder how they do that? They've allocated upstream channels for the STBs to talk to the Headends.... Also typically while the spec calls for 5-42mhz, typically again anything under 20mhz is not used, its just too noisy to be able to carry anything useful. So, after you leave VOD their room, you have typically between 26 and about 40mhz...so about 4 channels of space available (14mhz @ 3.2mhz spacing...about 12.8mhz)...
This is probably cable's greatest weakness...it can push all the DL it wants, but UL speeds are going to be constrained unless node sizes become extremely tiny (50 modems per node or probably 150 homes passed which sounds really expensive on paper) + TPIA on top of it?...I guess we'll see what happens on the 26th but I'm skeptical.
