It’s worth noting that cable’s phone business has grown in a fairly short period of time. The current competitive age can be traced back to the passage of the deregulatory 1996 Telecommunications Act. Following that, the cable industry invested more than $100 billion in private capital to upgrade its network infrastructure in order to provide broadband services.

But even before today’s IP-based phone service, some operators took the plunge into phone. Back in September of 1997, Cox Communications launched circuit-switched phone service in Orange County, California. Comcast (via its acquisition of AT&T Broadband) also has a base of circuit-switched customers that were generated following the acquisitions by AT&T of TCI and MediaOne in 1999.

NCTA has been drawing attention to the DOCSIS 3.0 specification for almost a year now. You may have seen the video of Comcast’s Brian Roberts demonstrating wideband at The Cable Show in Las Vegas last year.

Big news this week as Comcast launched wideband service in the Twin Cities on Thursday. It’s a new extreme high-speed Internet residential and business service featuring up to 50 Mbps download and up to 5 Mbps upload speeds. Comcast will be launching to about 500,000 homes in the Minneapolis-Saint Paul area. In addition to the new hi-speed tier, Comcast is also increasing upload speeds for its residential Performance and Performance Plus service tiers for no additional charge. For example, the 6 Mbps/384 Kbps Performance tier will increase to 6 Mbps/1 Mbps and the 8 Mbps/768 Kbps Performance Plus tier will go up to 8 Mbps/2 Mbps

As I posted previously, Brian Roberts mentioned DOCSIS 3.0 rollout during his CES address a few months ago. Plans are to roll out DOCSIS 3.0 to about 20% of Comcast’s markets by the end of the year.

There was coverage on Ars Technica, Engadget, Gizmodo, and the NY Times‘ Bits blog, but I was intrigued to see this post, which seemed to be from one of the first business customers to sign up for the service.

My experiences thus far have been amazing. When we first started to use it after the install, I broke into a huge grin as pages loaded instantly and I ran a 345MB update which hit my downloads folder and completed in what seemed like two minutes (it actually downloaded so quickly I forgot to watch it and time it). I’ve been achieving ~40mbps down and 3.4 to 4.1mbps upload speeds on average (which, of course, are dependent upon so many variables like internet traffic, server load and so on) so multi-use of our broadband connection has become more useful.

Nothing like first-hand reports.

Just to review a few fundamentals, DOCSIS stands for Data over Cable Service Interface Specifications. Cable operators right now use one 6 MHz channel slot to deliver high-speed data service. DOCSIS 3.0 describes a methodology for channel bonding, which allows you to combine 2, 3, 4 or more DOCSIS channels to increase the speed and throughput of the high-speed data service. The bonded channels do not have to be contiguous.

If you’re a cable customer, all you really care about is faster speeds. But the impact is broader, since DOCSIS 3.0 means better bandwidth utilization, improved video quality, enhanced security, better reporting to manage traffic, and enhanced tools to detect plant problems.

A couple weeks ago, I mentioned cable’s own digital transition, and that shift of channels from analog to digital that frees up channels that can then be bonded to provide faster Internet access. In addition, it will allow cable operators to eventually provide video over DOCSIS services, also known as IPTV. For bandwidth efficiency, 3.0 allows operators to dedicate and isolate a video downstream to any and all users who want to watch it at the same time, in a simulation of the way linear TV works.

So, the full impact of of DOCSIS 3.0 is still to come.

NCTA’s CEO Kyle McSlarrow was featured on Ad Age Magazine’s online video series 3 Minute Ad Age earlier this week.  McSlarrow recently addressed the Association of Cable Communicators (ACC) - the industry’s association for public releations practitioners.  In a conversation with cable consultant Steve Effros, McSlarrow raised, among other things, the relative lack of discussion about broadband policy among the Presidential candidates and the status of the DTV transition.

ACC will be posting the full discussion soon.  Until then, Ad Age has the video.
