Does that mean I'll only see speeds like the ones I have if I stay with the 4200 and will only be able to get the higher speeds if I buy a 5100? That really stinks.
Don't worry about that too much. The SB4200 can be upgraded to docsis 1.1 and that will be capable of plenty of extra speed for the next 2 years. Regardless of what you have read earlier in this forum, the upgrade to docsis 2.0 and the higher upload rates is very difficult and time consuming to do. Upgrading the CMTS is the easy part. Changing to higher upload rates will be very difficult. Because of the amount of hardware upgrades to the infrastructure to limit RF noise problems on uploads to get the higher speeds, even when docsis 2.0 is implemented, the very high upload rates that are theoretically possible won't be implemented. You will get your money's worth out of your current modem.

Phew, I was already getting my money out and counting pennies to pay for the 5100.  |

Actually, the 5100's are pretty cheap. In Best Buy they're selling them for $50 after rebate. I'm 99.9% positive that they will work on our system since they were mixed on the same shelf as the Comcast self-install kits.

Yes some Comcast nodes are 1.1 CAPABLE, but only the areas with digital phone are using the 1.1 features, and none of the 1.1 modem features are enabled. Hence why we do not push 1.1 firmware to the 1.1 upgradeable modems even though we have it availible.

"Have you ever stopped to think why NO cable isp currently (except for a small one I know of in brazil who just opened plant and all and only has a cpl hundred customers) uses QAM upstream?"
They'd probably all be using BPSK (1-bit/symbol) if that were in the spec. They're more interested in stability and ease of operation than in pushing the limits. |

If I were to go purchase a 5100, what would I have to do to get them to remove my old one and provision the new one? I thought they didn't like to do that. |

You just call them and say I bought a new modem and need it provisioned

Comcast wouldn't have any problem with you getting a new modem. Make sure your new modem is plugged in and has a solid connection. Then call Comcast and give them the MAC of your new modem. They'll (or at least they should) remove the MAC of your old modem and add/provision the new one. Just keep in mind that if you have a router and you cloned the MAC of your old modem, you will have to change those settings. At the very least a release/renew or reboot of your computer (if not going through a router) would be necessary.
In my case, when Comcast mailed me a new modem to replace my CyberSURFR, they forgot to remove the MAC of the old modem. Neither I or they realized that I had 2 modems on the account (only being charged for 1) until I switched to Pro and they had to re-build my account and reprovision my new modem (Terayon TJ 615).
If we ever do get multiple 5mbit connections to our house, it would be kind of cool to get close to maxing out the cable modem, wouldn't it?

I'd be keeping comcast. i dont like the way that ool has handled the whole capping issue and their definition of an 'abuser'. 384 or 512kbps upload with no BS is worth more to me than 1000kbps upload and always wondering "am i going to get capped for this?"

Because other countries that arent as greed oriented can use it to offer better service levels. cablemodems arent only a USA item.

DSL Prime & Comcast speed
Folks
I'm the guy who writes DSL Prime and thought to clarify what I wrote. (Yes, of course I read DSL reports. It's great.)
First, the going to 3 mbps is direct from the CEO of Comcast, who didn't put a time frame on it but suggested it would be fairly soon. He's doing that instead of dropping prices to meet Verizon, he told a wall street group.
The reference to "tripling" was not about speed but about the number of cable channels he would dedicate to the service. Currently, modems use a single cable channel and deliver a shared 28-38 mbps to perhaps 500 homes. Individual users have their rate limited to perhaps 2 mbps.
Where speed and price go is very much an issue of future competition, and very hard to predict.
The "multiple 5 mbps" is from an earlier conversation with Comcast, and very much is a long range goal, not something soon. That would presumably include multicasting video (probably HDTV compressed) to meet most of the demand, and a relatively limited number of "unicast" individual video streams. Comcast's planning is based around many homes having two or three TVs "multiple" and 5 mbps being a likely compromise instead of the 19 mbps of pure HD. Video requires so much bandwidth that rules their network planning, with internet data secondary. There are some very interesting network design issues, but that kind of capacity is far away. However, they are already buying some equipment with extra capacity to make this stuff possible, such as multiple GigE connections to some nodes.
Always flattered when Justin picks up my reporting, which I've given him the right to reprint as he chooses. But I'm not a cable expert, just happened to be reporting from an event where Roberts spoke.

One comment that might make some sense of this: currently Video on Demand is delivered on multiple 6Mhz channels (carrying MPEG-2) that are completely separate and independent of the DOCSIS data pipe. This arrangement has the advantage of being compatible with the installed base of set top boxes. But in the long run, what is desirable is a single unified fat data pipe that carries all interactive traffic: Internet, VOD, Voice, and whatever else comes along. It's the cheapest and most flexible way to do things. (Broadcasting will continue to use the legacy 6Mhz channels, whether analog, SD-digital, or HDTV).
I'm speculating here, but I think this is what Mr. Roberts envisions. |

and you dont think that if Comcast raised their upstream that they wont monitor the bandwidth more think again.they will be capping people just as fast. |

the problem with that is that a 5Mbps stream is not even close to a HD resolution.5Mpbs is standard DVD quality which is a SD.If they are going to push HD they are not going to be able to compress the video signal without people noticing the grainyness.Once the analog system is dropped that will free up a ton of bandwidth for full resolution HD and with the right equipment they can put 2 1080i streams on one 6Mhz channel without any loss. |

``If they can do what they say they can do, they have brought it up to a point where it takes a wellfinanced, sophisticated organization to carry it further,'' said Merle Temple, Augusta-area public relations director for BellSouth. He brought an engineer to the demonstration to see if Mr. Fogal's technology offers highquality communications on ordinary telephone wires at a fraction of the cost of fiber optic cable."

| Ok thats good. I was in a test area for when ATTBI raised the upload speed to 256, so maybe they'll test the new download speeds here. I'm probably going to switch to verizon anyway, but maybe if Comcast makes me a better offer to stay then I will. |
