[Speed] Heads-Up: Time to Replace Your DOCSIS 1.1 Modem

From the FAQ:

What does it mean when a device is End-of-Life (EOL) or End-of-Support (EOS)?

An End-of-Life (EOL) device is any XFINITY Internet or Voice device that needs to be replaced after being made obsolete due to changes in technology. Older devices, such as cable modems, were not designed to support the faster speeds and improved security features that are available today.

For example, we have upgraded our network from the original DOCSIS 1.0 standard to the significantly improved and much more recent DOCSIS 3.0 standard. If you currently use a DOCSIS 1.1 device, you will not be able to enjoy the full benefits of our service such as higher speeds, greater security and better reliability.

In addition, an End-of-Life modem in most cases means the device's manufacturer has stopped providing support for a device, such as firmware dates and bug fixes. Occasionally, we will find a device that is defective and no longer sutable for use.

End-of-Life basically means we will no longer install the device, either as a new or replacement device. In addition, it means we no longer recommend that customers purchase these devices, whether new or used. It is also an advance warning that the device will soon need to be replaced.

Typically, if a device is identified as End-of-Life, it will subsequently move to End-of-Support (EOS) status. This means that when a device reaches End-of-Support status, it will no longer work on our network or be compatible with our network and/or services.

Ready to upgrade?
If you lease a DOCSIS 1.1 device, chat online a Care agent to order a self-installation kit for a replacement device.

If you own your device, you can either choose to lease one from Comcast or purchase a new one yourself. To purchase a replacement, visit your local electronics store or go to »mynewmodem.comcast.net to buy online now.

And to better serve you.
Network management becomes a lot more efficient once the ENTIRE network is D3.
more efficient=more available bandwidth and speed potential.

eliminating D1.1 is the next step forward.

getting rid of D1.1 also gets rid of lots of very old hardware, Old hardware that could have been causing unneeded TCs.

Yes, the 16-QAM upstream carriers are currently needed to support any remaining DOCSIS 1.X devices on the network.

However, unless a move to S-CDMA is eventually made, I think it could be possible that some 16-QAMs might still be placed in the noisy, sub-20MHz region, where their lower SNR requirements (vs. 64-QAMs) come in handy, in order to provide a bit more (bonded) uplink speed.

I'm glad to see that Comcast does not appear to have used this as an opportunity to sell a cable modem for $200.00 when you can get it anywhere else for $85.00.

There was a time that I saw Comcast prices upwards of $200.00 for a Motorola SB5100 ... ridiculous.

A good question, Maybe Jason can answer for certain.
I'd guess that because D2 is closer to D3 than D1.1, but was never widely adopted, it can co-exist for the meantime, which may not be more then a year or two which is why he suggested a D3 modem, and probably should have hinted at IPv6 CERTIFIED (per comcast's list) for best future longevitity (only the future is future-proof)
I think the logistics of replacing EVERY rented modem dictates the staged replacement ("ah, run down to bestbuy and get 10-12 million D3 modems, before lunch, would cha' " )

DOCSIS isn't used by just modems and eMTAs.

Don't forget all the cables boxes (DCH, DCX, etc.) with non-D3 modems in them that will be used as iGuide is replaced.

Along with that are various status monitoring modules on plant power supplies and other things that may use DOCSIS modems for communications.

I do agree. Doing it in stages (remove the 1.0 first, then the 1.1 next, and then remove the 2.x last) is the best move.

Not to mention, those with D2 eMTA's (like myself) have very few (if any options) to purchase a D3 eMTA on their own. While I rent, I know there are quite a number of people who do purchase, and if they have a D2 eMTA now, and want to go buy a D3 one, the options are not very good (if any exist at all).

Hopefully when Comcast does force the D2's off the network, there will be more options to purchase a D3 eMTA then there are now.

I saw on the rate sheet (printed flyer with Comcast rates and fees picked up from local Comcast office) for my area that you can purchase a voice/data modem from Comcast. I am wondering if it is possible to purchase an Arris TG862G or what modem I would be supplied with if I purchased a voice data. I own an Arris TM722G (that is not in use) at Best Buy when they were selling them. The only modems I see on the website you mentioned is the data only modems.

I currently rent the TG852G modem but am interested in purchasing it as I prefer to own and not rent. I would like to purchase an EMTA that supports 8x4 channel bonding vs 4x4 channel bonding.

I wish I still lived in Iowa; Everything there from rent and groceries to Cable TV is much cheaper in Iowa (especially with an overbuilder in town).

Me too. As it stands, there's no easy way to upgrade to an 8x4 EMTA.
