Cable's early adopters of telephony

November 30, 1998 7:00 pm | by Michael Lafferty, Associate Editor | Comments

While analysts have pointed their fingers at the pending merger of AT&T and TCI as the first true sign of impending telecommunications competition, the fact is that a handful of operators are already taking it to the RBOCs. These MSOs are reaching out and touching thousands of subscribers by leveraging their upgraded networks to deliver not only video and high-speed data, but facilities-bas...

It's a circuit-switched world for now, but everyone's talking about IP

November 30, 1998 7:00 pm | by David Iler, Associate Editor | Comments

In a short span of a few months, telephony-over-cable has quickly moved from lady-in-waiting to center stage. This "marriage" of telephony and HFC was consummated this summer when the most sober of corporations, AT&T, announced its merger with Tele-Communications Inc. AT&T further drove home its commitment to telephony-over-HFC when, in October, it placed an initial order of $50 million...

Who's driving the broadband bus?

October 31, 1998 7:00 pm | by Andy Paff, Chief Technology Officer, Worldbridge Broadband Services | Comments

Cable operators tend to think narrowly about the HFC (hybrid fiber/coax) local access world when it comes to emerging telecom standards and services.

Set-top box operating systems

October 31, 1998 7:00 pm | by David Iler, Associate Editor | Comments

The "brains" inside the next generation of advanced digital set-top boxes will be any one of a number of small, sophisticated operating systems that fall within the burgeoning category of "embedded applications." For now, PowerTV, the operating system chosen for Time Warner's Pegasus box, and Windows CE, the OS apparently selected by Tele-Communications Inc.

Set-top boxes: Get ready for the never-ending upgrades

October 31, 1998 7:00 pm | by Michael Lafferty, Associate Editor. | Comments

As the cable industry ventures ever further into the digital era and begins wide-scale deployment of set-tops, like it or not, the industry will discover, and more importantly have to learn to live with Moore's Law-that components will get better, faster and cheaper every 18 months. As a result, cable professionals will be living their own version of the popular children's fable and movie, "The...

OpenCable closing in on a standard

October 31, 1998 7:00 pm | by Michael Lafferty, Associate Editor | Comments

Just like cable modems, the key to an interoperable, retail-available digital set-top is a standard to which manufacturers around the world can build. And just like cable modems, the digital set-top standard has made incredible progress in a short amount of time. It was only a year ago that CableLabs' Executive Committee officially stepped on the gas and put the "OpenCable" standardization effo...

September 30, 1998 8:00 pm | by Michael Lafferty, Associate Editor. | Comments

Conventional wisdom says high-speed data-over-cable means you have to be big for the economics to work. As a result, companies have been designing huge data networks and planning for the traffic they'll carry. Yet interestingly, mid-sized and small operators are rushing into the high-speed data industry, often beating their larger brethren to the punch.

Christmas On Hold?

September 30, 1998 8:00 pm | by David Iler, Associate Editor. | Comments

The Internet has always been about waiting-waiting for Web pages to download; waiting for more reliable and faster service; waiting for that killer application. Now the cable industry, with bandwidth-hungry customers anxious to move into the fast lane of the information superhighway, waits as the clocks ticks on an important deadline.

Evaluating upstream modulation techniques

September 30, 1998 8:00 pm | by Jeyhan Karaoguz, Ph.D., Principal Staff Engineer, Research and Advanced Development, Internet and Networking Group, Motorola. | Comments

The North American cable industry's adoption of the Data-Over-Cable Service Interface Specification (DOCSIS) is solving long-standing problems of interoperability.

September 30, 1998 8:00 pm | by Roger Brown, Editor | Comments

Let the finger-pointing officially begin. The long-awaited transition to digital television is running into snags. Given its complexity, that probably doesn't come as a surprise to most engineers. But for politicians and others, it's shaping up to be a public embarrassment. With digital TV scheduled to go live in November, you can be sure that if there are delays, regulators will come looking f...
