Re: Dream Modem - 24x8

Arris says the decision to use the E6000 as a massively dense Docsis CMTS represents a "middle step" that addresses the near-term needs of cable operators as they continue to increase downstream capacities and bump the amount of bandwidth per subscriber by shrinking service groups.

Running the E6000 in CMTS mode will come in particularly handy when cable operators start to bond as many as 16 downstream channels, says Todd Kessler, the VP of product management for Arris's CMTS platform.

ARRIS will will be displaying their new Intel Puma 6 (»newsroom.intel.com/community/int···ble-show) based gateways at this week's Cable-Tec Expo.

From today's Light Reading Cable's cable news round-up (»www.lightreading.com/document.as···lr_cable ):

Arris Group Inc. is the latest cable modem vendor to introduce Docsis 3.0-based gateways that take advantage of the full capabilities of the Puma6, a chipset from Intel Corp. that can bond up to 24 downstream channels and produce speed bursts close to 1 Gbit/s. Arris's new line of gateways also will be outfitted with MaxLinear Corp. tuners and video-optimized Wi-Fi chips from Celeno Communications.

Arris's latest lineup, which will be on display at this week's Cable-Tec Expo in Orlando, includes two gateways that bond 24 downstreams and eight upstreams, and five models that use the Puma6's 16x4 configuration.

Other vendors are sure to follow with 24x8 D3 gear, but Hitron Technologies Inc. was the first to announce a model, and already has plans to submit its new gateway for CableLabs certification next month.

Looks like Comcast will be deploying those new ARRIS E6000 CMTSs:

Cisco Extends Bridge to CCAP
By Jeff Baumgartner, Light Reading Cable - December 12, 2012
»www.lightreading.com/document.as···lr_cable

On Wednesday, the company launched two capacity-boosting cards -- the Performance Routing Engine (PRE5) and the 3-Gigabit Shared Port Adapter (3GSPA) -- made to snap into its widely deployed flagship CMTS, the uBR10K. They'll act as an intermediate step toward CCAP, an architecture meant to help cable unify all services, including video, under IP.
:
Cisco says trials are planned with "several major" cable operators in the U.S. and abroad starting in the first quarter of 2013. Cisco didn't name them, but Comcast Corp. and Time Warner Cable Inc., two of Cisco's key customers, are expected to be among the first MSOs to test and deploy CCAP.

Comcast has already issued a CCAP request for proposal (RFP) and has said it will begin some initial deployments this year. More details about that could emerge today at noon E.T. during a Light Reading Cable webinar sponsored by Cisco that will feature John Mattson, Cisco's senior director of strategic marketing, and Jorge Salinger, Comcast's VP of access architecture.

Re: Dream Modem - 24x8

Guess my 8x4 Moto will be fine for now - still waiting for that 24x8 though if I were to ever buy anything newer. Hell 32/16? :P

Since I doubt my ISP is doing anything soon, I think i'm good for now. Would still love a 100Mbps and say 20Mbps up even though my 50/8 doesn't slow me down now.

Broadcom is now launching their new line of DOCSIS 3.0 chipsets that can bond up to 24 downstream channels, matching the capabilities of Intel's Puma 6 ones:

Very interesting. A modem with one of these chips would do Comcast's current fiber 305 service easily.

Think this would be what they need to bring it to the masses outside of the Metro-E area?

I don't think Comcast will ever offer 305Mbps service using DOCSIS 3.0. If they ever do offer such speeds over their HFC network, it would probably be by using equipment built to the new, currently-under-development DOCSIS 3.1 specs (see: »Re: Dream Modem - 24x8).

Will Broadcom Go for More Than 1-Gig?

Yeah, I did some reading on it and you're probably right. I do find it funny though. I just got the D3 upgrade here about 3 weeks ago, after 5 years of waiting. Docsis 3.1's first products aren't due until some time next year. Wonder how long it'll take to get me that upgrade?

Keep up the goodies. I'm drooling over here.
