Re: Let's keep all DOCSIS 3.0 Discussion in this thread, please
So I live in Detroit Market.. If they decide to try docsis 3.0 here.. do they choose certain people to give modems out to.. or you have to call them and tell them you want to try out?? Jw |

Many of us work on these issues everyday, as mentioned DOCSIS uses 6.4MHz channel widths. On upstream it can yes, not downstream. Downstream DOCSIS comes in 6MHz and 8MHz flavours.
The RF carrier downstream is the same on DOCSIS 3 as with previous versions, yes it is marginally wider due to raised cosine shaping but the 'wanted' bandwidth of the signal is exactly the same as with previous versions, same symbol rates, same modulations. It is in no way the cause of any incompatibility.
Unsure why you'd be seeing issues due to downstream changes, maybe some incompatibility between certain modems and certain CMTS but that really should not happen on a fully compliant DOCSIS 3 CMTS and DOCSIS CPE.
There are no RF differences between D2 and D3. The differences are in the MAC layer and the ability to bond the channels which are, in D2, discrete. |

Re: Comcast New England Customers - Conversions beginning
said by BSD24  :COMCAST NEW ENGLAND CUSTOMERS - Comcast will be implementing Docsis 3.0 conversion to allow for higher speeds. Conversions are beginning to take place across the New England Division. This work is being done nightly from 12am to 6am. Just thought people should know what will be coming soon, if you live in a Comcast area of New England. I believe Lawrence, MA is already testing it, other areas are performing upgrades on the network, as I said before this will be taking place between 12am and 6am. I believe most or all of New England (CT, NH, MA, etc.) will be done soon in some areas, all by end of 2008 from what I have heard. Is there any definitive way to take advantage of this yet, or will buying an SB6120 just result in me getting a D1.1 config file and the same service I have now?

Until they announce it as a tier there is nothing you can do. You wouldn't even get to get the proper config file with those speeds.
I know it sucks waiting I got lucky it was just announced and I could get everyone else has to wait.
Hang in there soon enough

Dayum....Chesterfield? (That is part of the Richmond, VA cluster, and the southern part of the old Mid-Atlantic Region.) That used to be primarily "Cisco Kid" territory (the big leased modems were the really large Cisco uBR cable modems; this was WAY before Cisco acquired either Linksys OR S-A). I wonder if anywhere else in the old M-A Region (basically, anywhere south or west of PA or DE, but noth of NC) is doing trials (Reston, VA is usually a test area). |

I've pretty much given up on Comcast in Colorado.
Comcast's competition here is Qwest, which doesn't offer TV service. Qwest offers ADSL2+ in a very, very few areas - otherwise, it's 7Mbps with 32ms of interleave-induced latency, and that's if your lucky. And don't even think about signing up without home phone service, because you'll pay through the nose.
So, with zero TV competition and very little Internet competition, Comcast doesn't have a whole lot of incentive to upgrade their network. We still have 65+ analog cable channels, we still have around 15 HD channels, and we still have crappy oversubscribed DOCSIS 1.1 Internet.
We have a perfectly good 850MHz cable system here. There's room for 150 full-bandwidth MPEG2 HD channels (even without SDV), plus 250 SD channels, plus 300Mbps of DOCSIS 3.0 goodness. The technology exists, right here, right now. Hell, most of it was developed right down the street at CableLabs (it's around 5 miles away).
But, you know what? I think that Comcast is a company that hates investing in infrastructure and technology. We still have the same crappy Moto cable boxes with the same crappy i-guide DVR. We still have tons of analog channels wasting bandwidth. And we still have crappy slow Internet. Comcast talks about deploying new technologies. Sometimes they do demonstrations. Sometimes they even deploy in a few markets.
But, at the end of the day, I've still got my TiVo HD with two S-cards (because they don't have M-cards in this area). I still have my crappy Thompson DCM425 cable modem that periodically loses sync because of line problems that Comcast won't fix. I still have crappy latency because my node is oversubscribed.
And, yet, I put up with all this crap because the alternative is 3Mbps DSL for $56/mo with Qwest. I guess that's the point. Here, there's no alternative. Here, it's Comcast or nothing. |

| bsoft,
If you could make the decision for your area, and swap Comcast's cable monopoly for one operated by another existing company that does things better, who would you choose and what are they doing better?
(In short -- Is it Comcast or is it the monopoly factor?)

| Similar situation here. Comcast around here isn't too horribly oversubscribed, so PowerBoost actually means something, but the highest internet tier is 8/2 Mbps for pretty darned expensive, especially considering the 250GB cap that's gonna turn on the day after tomorrow.
Problem: there's little to no competition. Qwest's fastest DSL package is 5/896 nominal, 4.25/700 actual, and that's on a perfect day. Usually speeds are a good bit under that...the DSLAM isn't fiber-fed so we're stuck with capacity issues at peak times. First-hop latency is 45-50ms if you're not doing anything with the connection, much more if you are.
If TW wasn't going to cap their service I'd say I'd rather be with them in a heartbeat. For about what I'm paying now, back home I could get a 15/2 connection. Verizon, Embarq or even Windstream DSL would also be nice; I'm not even talking about FiOS here and we're looking at faster speeds than Qwest offers...with reference to Verizon I'm talking about their new 7 Mbps DSL tier.
DSLExtreme anyone? AT&T DSL (not even talking about UVerse)?
Cable-wise, I dunno. Armstrong Zoom? Grande Communications? Insight? WOW? I want sustained speed, not PowerBust.
There is a WiSP around here but I think a 5 Mbit connection is $60 per month, though that's better than $47/mo for Qwest for a connection that isn't even that fast. Not sure why "cheap" DSL starts at $40/month for dry-line service...and that only pays for 1.5 Mbps down!
So yes, competition would be good. But there are also much better companies to have as your monopoly\duopoly. Heck, it'd be awesome to have the old WOW DSDN back. Ah well... |

(In short -- Is it Comcast or is it the monopoly factor?) Unlike Fios - Comcast has to upgrade networks, get rid of analog, and do some other changes to get closer to what Fios can offer. These changes take time and plenty of money. Can't wait to see how things go as things continue to change. |

It's a new system, they wanted to offer TV service, so they ran FTTH. If you want to think of it as a upgrade, its a upgrade to their network, and phone service, but not an upgrade for tv, since it is new to TV, and FIOS internet is technically brand new. |

Thats also why they are an all-digital tv provider, you have to have a box for every tv, no cable direct. Comcast didn't abandon their network, instead they are upgrading. So its going to take time and money to do this, to basically catch up to what Fios is able to offer. Comcast still has plenty of Cable-Direct customers still feeding off of analog service. |

New England customers..take it for what it's worth...And call me a skeptic myself until I see the proof in a speed test..but I was told today by a source I consider reliable
that New England customers on the Standard 42.95/mo. tier will be seeing their speeds increased....And flat out doubled in fact...to 12,000/2000 as part of the docsis 3.0 upgrades currently in testing around New England.
And furthermore, the 22,000 / 5000 tier will reportedly be priced at only 62.95/mo.
Hopefully it turns out to be the case. |

One would think that the 22/5 would replace the 16/2 on the business account if the 22/5 would be 62.95/mo for the residental.... that would be nice if this was true. I could def use a 22/5, the 5 up would be really welcome. 
I guess I will have to wait till about 2010, as CO is pretty low on the upgrade list due to Qwest being the tel company. On the otherhand, 2 weeks ago I did get upgraded from QAM16 to QAM64, as did all of the Comcast connections I have tested around the metro area. |

Rick you are correct. 10/21/08 is the roll out for NNE. 6/1 downloaders will be doubled to 12/2. all 8/2 downloaders will be 16/2 for free.
The 22/5 will be 62.95
The 50/10 will be 139.95 |

| DOCSIS 3 FEATURES need new HARDWARE, a simple modem firmware upgrade won't do it.
A DOCSIS 2.0 modem will work fine on a DOCSIS 3.0 system if you don't need any of the new DOCSIS 3 features like IPv6, channel bonding, increased security, better diagnostics, etc. |
