Re: Unofficial Next Comcast Speed Upgrade Rumor Topic Part II
OK, birdy whispered rumors this morning. 
Birdy said there is a buzz among some of the techs:
quote:
...that the whole network is being upgraded right now to work with the Docsis 3.0.
Hmmmmmmm ... if this has any truth in it, could this be why some have seen the high speed testing? 
Remember this is a rumor thread. Please don't shoot the messenger!

I can believe they are starting to upgrade towards full DOCSIS 3.0 compliance..........but that process could take years (and billion$ ) before 3.0 is system wide.
Because DOCSIS 3.0 is (should be) backward compatible, not all equipment MUST be replaced at once, and new modem deployment would be the last step. |

| Some Comcast people were working on a node in my area and I stopped to talk to them. One of them was a field engineer.
He said he has heard DOCSIS 3.0 being mentioned but didn't know the whole story.
He did say that as of 2009 that all channels have to be digital and theoretically they could give 100mg down and 10 up.
When I asked him if that could happen where I live he said it all depends on the competition.
Where I live we still get the occasional moose walking down the road and no competition in sight so guess I will just have to be happy that I don't have to use dial up. |

Here's is the modem that is probably closest to DOCSIS 3.0 certification.
»broadband.motorola.com/catalog/p···ctID=486
It has been used by CableLabs in several tests/demonstrations of DOCSIS 3 technologies and currently deployed by StarHub of Singapore for their pre DOCSIS 3 MaxOnline Ultimate plan (100/2). |

Why would 3.0 even be implimented if no one were able to take advantage of it ??
That's not logical to me...... |

Why would 3.0 even be implimented if no one were able to take advantage of it ?? That's not logical to me...... First step (for each deployment area) would be to plan and engineer any nessesary line extensions or improvements. then schedule and complete those, adding a DOCSIS 3 CMTS as it is completed. At the same time or before they must shift the DHCP and DNS to be fully IPv6 compliant (required by DOCSIS3)and change channel allocations splitting or combining nodes, etc Up until this is done CC only needs a few thousand modems for QC testing and tech training.
Once customer deployment begins they may require several million modems within a couple years time (not everyone will feel the need to jump to a higher (and probably more expensive) tier at once. older 1.1 & 2.0 modem will continue to work at the lower speeds.
One major public relations problem will be the timing.
Obviously, they either have to delay switchover until the vast majority of areas are ready (expensive and slow) or do it region by region, and withstand the screaming from un-upgraded areas ("I pay the same as Region X users but can't get the speeds they get............" think of the current " they got upgraded first" whining seen here everyday, times 10)
once CC give the word to one or more vendors that they need a million modem by (insert date) how long do you think would it take to ramp up the factories in china,etc,. to pump them out?
The longer it takes to get to that point the more compiant designs will be available, important for CC cost control.
And all through this they must continue to maintain the current system without major interruption. |
