D3 Is the New Black – And SPs of All Sizes Are Trying It On

DOCSIS 3.0, a.k.a. “D3″, is definitely one of the hottest trends we are seeing among cable service providers of all sizes today. Cisco’s DOCSIS 3.0 solution has now been deployed by more than 35 service providers and more than 135 sites worldwide. In recent months that momentum has shifted to North America where more than 45 sites have deployed DOCSIS 3.0 solutions with Cisco technology. See the deployment map below.mapCable service providers are using DOCSIS 3.0 deployments as a competitive weapon rather than a defensive measure against FiOS and other FTTH services. Operators recognize the solution flexibility and efficiency brought by Cisco’s DOCSIS 3.0 solution, which helps them to add low cost DOCSIS 1.x or 2.0 capacity with the exact same infrastructure enhancements that enable DOCSIS 3.0.DOCSIS 3.0 is certainly not a one-size fits all approach. Cisco has been working on D3 rollouts with a wide range of customers who manage subscriber bases from the several hundred thousand range to the multi-millions. Midcontinent Communications, (which serves more than 240,000 customers in 200 communities throughout North Dakota and South Dakota and in Minnesota markets) just announced this week the deployment of its first Ultimate Broadband service over Cable using Cisco’s DOCSIS 3.0 solution, including the Cisco uBR10012 Cable Modem Termination System (CMTS) and DPC3000 Cable modem products. Midcontinent is now offering the DOCSIS 3.0-based “MidcoNet Ultimate” broadband service, delivering broadband speeds of 50 Mbps and 5 Mbps in the downstream and upstream respectively in West Fargo, ND and Sioux Falls, SD. The deployment of this DOCSIS 3.0 solution from Cisco has enabled Midcontinent to potentially deliver speeds of 160 Mbps in the downstream and 120 Mbps in the upstream with no change whatsoever to the network infrastructure or CPE devices being deployed. They can also expand bandwidth for their existing subscribers while enabling the delivery of a 100+ Mbps service to subscribers who would like to experience lightning fast broadband speeds. Perhaps most importantly, we have enabled Midcontinent to deploy this D3 solution by ensuring that migration CapEx and OpEx are minimized, while enabling a targeted delivery of service and a faster time to market.So what is the ‘big deal’ about D3 and why is it such a hot trend? It is a key investment for their future to deliver rich media and the popular applications consumers will want. With our DOCSIS 3.0 solution technology, we are not only enabling high-powered Internet speeds, but also providing a truly flexible foundation for our service provider customers to deliver more personal, more interactive and more social consumer services such as IPTV, WebEx, unified communications and even TelePresence over their networks. We continue to evolve our D3 solution to further improve efficiency and scalability, so stay tuned for more news and future posts to come on this.

  1. It seems to be a good solution. I want to know without having ATM backhaul could we rollout the services.

    Murali – Need to update the map, although putting a star”” on New Hampshire would probably cover the entire state. I upgraded to DOCSIS 3.0 about 2 months ago (Comcast “”Ultra”” service tier) and LOVE IT! Just got off a video Webex call with Japan that looked great. Once you go D3 you can’t go back…”

    Hi Shivlu,Indeed–The backhaul( edge and core) components stays intact and the only thing you are touching to enable this Ultra high bandwidth to the home is to beef up access by increasing the downstream bandwidth capacity of the CMTS. The cool thing is that Cisco designed it so that you can do that in a seamless and non-disruptive way. Over time, you’ll have to consider the implications of higher bandwidth services (downstream and upstream) on your aggregation networks, but at this point you’re good to go.Murali

    Hi Greg,Once you go D3, it’s hard to look back. We’re fortunate that we’re seeing SPs roll-out fiber and D3 based services. Telcos may have fiber based deployments but cable has Docsis 3 to respond and compete effectively. Think about your use-case, you are not only downloading video streams when engaged in webex meetings but you’re also streaming your own video and powerpoint files. This is precisely where D3 shines where downstream and upstream can compliment the user experience. With video based applications dominating, D3 becomes a solid platform for service innovation by SPs and the eco-system at large.With the momentum we’re seeing, many others will soon experience the benefits you’re describing. Enjoy it Greg!

  5. Can I buy a D3 modem anywhere and for how much if so?
