Clearing out the cobwebs

March 31, 2000 7:00 pm | by Roger Brown Editorial Director, Telecom Group | Comments

A few random notes I've had over the past few weeks: When you live in the limelight, you need to be careful of everything you say and do. For people like America Online's Steve Case and Global Crossing's Leo Hindery, I can't help but wonder what it must be like to make some very public statements, only to have to spin them later.

Hopping the gap

March 31, 2000 7:00 pm | by Staff | Comments

... part II Newbridge, which just won the contract for buildout of a nationwide LMDS network in Belgium by British Telecom subsidiary BT Belgium, has taken pains to integrate wireless broadband access capabilities into its multi-platform edge switches to support the needs of major U.S. carriers like MCI Worldcom, Sprint and NextLink Communications for efficient means of operating over a mix of ...

Making the switch to (and at) Layer 3

February 29, 2000 7:00 pm | by Thomas G. Robinson, Executive Vice President, CBG Communications | Comments

On the surface, the seven-layer OSI (Open Systems Interconnect) model seems relatively easy to grasp. From the transmission medium-oriented physical layer (Layer 1) to the data program management-related application layer (Layer 7), OSI was designed as a logical flow model to define all the elements necessary to enable any two computer systems anywhere to communicate.

Flip the switch on modem activation

February 29, 2000 7:00 pm | by Michael Lafferty, Associate Editor Reality is Finally Starting to Set in. | Comments

Over the past two to three years, as the cable TV industry fondly made predictions about the impact a standards-based cable modem would have on its bottom line, it gave only passing attention to how millions of these high-speed money makers were actually going to be deployed. Fortunately, the magnitude of this undertaking is finally getting the attention it deserves.

The biggest auction yet?

February 29, 2000 7:00 pm | by Jeffrey Krauss, Spectrum Speculator and President of Telecommunications and Technology Policy | Comments

On May 10, 2000, the FCC is scheduled to begin what could become the biggest (dollar-wise) spectrum auction yet. The bands 747–762 MHz and 777–792 MHz will be auctioned. This could bring in more dollars than the PCS auctions, because this spectrum is more desirable. Or maybe not, because the winners won't get to use the spectrum for a number of years.

Cramming more in the return path

February 29, 2000 7:00 pm | by Fred Dawson Contributing Editor | Comments

Whether the mega mergers roiling cable lead to intense new competition among top players or to new levels of cooperation, it seems safe to say that one result of the intensifying scramble to stay on top could be the eventual dominance of cable's infrastructure in local broadband communications transport.

Realizing the promise

February 29, 2000 7:00 pm | by Jim Chiddix, President, AOL Time Warner Interactive Personal Video Group | Comments

I'm glad to have an opportunity to write my first column for this magazine in 10 years. An enormous number of things have happened in the cable industry since then, although, looking back through old issues of CED, I see the seeds of many of the things that are transforming the industry today. Thirty years ago, the cable industry was tiny, serving subscribers scattered through small-town Americ...

Trade show relief?

February 29, 2000 7:00 pm | by Roger Brown Editorial Director, Telecom Group | Comments

It's a tad too early to tell for sure, but last month's announcement that the NCTA is taking a long, hard look at the number of cable industry trade shows could sound the death knell for some of the small, regional conventions. At the risk of being considered cold-hearted, I say it's about time. Barraged with complaints about lack of attendance, dwindling exhibitor support and a changing landsc...

MSOs take VoIP for a test drive

January 31, 2000 7:00 pm | by Fred Dawson Contributing Editor | Comments

Now that the cable industry has united behind a uniform approach to delivering IP voice services over its networks, a growing number of MSOs are pushing ahead with plans to deploy the new platform on a wide scale as quickly as possible. Time Warner Cable, Comcast Corp. and Le Groupe Videotron have made it known they're testing the technology in preparation for commercial launches, and vendors r...

Ops adopt migratory node size strategies

January 31, 2000 7:00 pm | by Craig Kuhl Contributing Editor | Comments

Passive and near-passive may be the operative words when deciding how many homes warrant a single fiber node, but when it comes to the economics of fewer homes per node, cable operators are showing signs of passive and near-passive mentalities. Fiber costs are falling, glass and optronics costs are stabilizing, and other key components to reducing node sizes are generally more affordable than e...

The biggest decision

January 31, 2000 7:00 pm | by Jeffrey Krauss, Local Loop Loiterer and President of Telecommunications and Technology Policy | Comments

What was the FCC's biggest, most important decision in 1999? I think it was the local loop line sharing decision that came out in December. It requires incumbent local exchange carriers (ILECs) to lease the high frequency portion of their wire pair local loops to competitive local exchange carriers (CLECs) for digital subscriber line (DSL) services.

Avoiding the demise of broadcast TV

January 31, 2000 7:00 pm | by Walter Ciciora HDTV is Essentially Doomed by the FCC's Rules on Simulcasting. | Comments

This column asks a difficult question: Does DTV mean the demise of broadcast television? And it presents a possible disastrous outcome which is an unintended consequence of DTV. This is not a prediction, but an inquiry into a possibility. Note that the issue is not whether broadcasters will cease to exist.

Meet the new boss

January 31, 2000 7:00 pm | by Staff | Comments

So, just who is this guy, this Steve Case, this soon-to-be new top dog of the nation's second-largest cable company? Like him or not, Case is a pure, in-your-face, entrepreneurial marketing genius. Starting as a youth, he brainstormed with his brother Dan, searching for ways to make money. Making the most out of the daily contact he had with people on his paper route, he sold seeds, Christmas c...

Flexing your bandwidth

January 31, 2000 7:00 pm | by Roger Brown, Editorial Director, Broadband | Comments

Increasing bandwidth demands from the roll-out of new services, coupled with falling costs of optical components and fiber cable, are forcing broadband network operators to once again review the way they're designing their networks. More often than not, they're becoming increasingly interested in reducing node sizes-sometimes to a level considered economically impossible just a few short years ...

Packet Man

December 31, 1999 7:00 pm | by Roger Brown, Editorial Director | Comments

Mark Coblitz has everyone faked out. His vast knowledge of arcane RF transport issues, the intricacies of TCP/IP protocol stacks, packet-based telephony and myriad other subjects often lead people, including engineers, to think he is one, but surprise! He's not. Similarly, some might see the bookish redhead as little more than a quiet, introspective thinker.
