Radical optical solutions demand review

March 31, 1999 7:00 pm | by Fred Dawson, Contributing Editor | Comments

... part II Opening a new window Upstream applications also represent one of the main reasons behind emerging interest in the possibility of opening the 1400 nm window to cable use. S-A, working with Lucent Technologies Inc., has taken the lead in this area, with tentative plans to develop an alternative to its own TDM and other strategies for maximizing return efficiency.


Securing a lifeline for cable telephony

February 28, 1999 7:00 pm | by Ham Mathews, Director of IP Business Development; and Glen Skrivseth, Technical Marketing Engineer, ADC Telecommunications' Broadband Networks Division | Comments

... part II Residential gateways Having understood the value of delivering lifeline service to the consumer, MSOs need to evaluate the residential gateway devices used to offer lifeline and other services. The three predominant solutions include cable modems, set-tops and ISUs. Each has their advantages and disadvantages.

Modem installers embrace new game plan

February 28, 1999 7:00 pm | by Craig Kuhl, Contributing Editor | Comments

Keeping it simple is the new mantra of cable modem vendors, manufacturers and cable operators as they prepare for the dawning of the modem installation age, and wrestle with the question du jour: Who's going to install these modems, and at what cost? Their agendas may be different, but each of the principals involved in the manufacture and distribution of cable modems and services is certain of...


In with the new

February 28, 1999 7:00 pm | by Roger Brown, Editor in Chief | Comments

MediaOne's decision to buck the industry trend by not choosing a conditional access scheme based on either Scientific-Atlanta or General Instrument technology comes as both a breath of fresh air and a case of an MSO finally putting its money where its mouth is. Instead of offering up the usual lip-service about wanting to open the market to a wider range of set-top manufacturers, MediaOne has t...

Closing the gap

February 28, 1999 7:00 pm | by Thomas G. Robinson | Comments

When it comes to personal telecommunications technology, I must be one of the Technology Smiths—you know, always trying to keep up with the Technology Joneses, but never quite getting there. I do have a PCS phone, but I sure would like to have one of those Iridium Satellite Digital communicators, and I haven't gotten beyond 56K (I've heard "cable modems are not yet available in your area,...

NGSO satellites Creating new spectrum capacity

February 28, 1999 7:00 pm | by Jeffrey Krauss, Satellite Orbiter and and President of Telecommunications and Technology Policy | Comments

Radio spectrum has become so valuable, that heroic efforts are underway to create new over-the-air spectrum capacity. For example, the Ku-band satellite spectrum is all used up, with satellites spaced every two degrees along the geostationary (GSO) orbital arc. The latest technology will allow non-geostationary (NGSO) satellites to share the Ku-band, with hardly any additional interference.

IP phone: Are operators missing a trick?

February 28, 1999 7:00 pm | by Fred Dawson, Contributing Editor | Comments

... part II Voice-over-VPN The same sort of learning curve is discernible in the early adoption of various modes of conferencing and voice-over-VPN (virtual private network) services that are taking hold here and there. As with the e-commerce opportunities, these activities point the way for providers of high-speed data access to develop value-added components by using the quality-of-service ca...

Is cable WIRED into home NETWORKS?

February 28, 1999 7:00 pm | by David Iler, Associate Editor | Comments

... part II The magic demographics that have captured the imaginations of the home networking proponents are based on the astounding growth of Internet usage and the popularity of home offices. The Yankee Group estimates there are more than 12.5 million multi-PC homes in the U.S., while estimates of U.


Harnessing Network Power

January 31, 1999 7:00 pm | by Gary Donaldson, Member Technical Staff, MediaOne Labs; Randy Midkiff, HFC Architect, MediaOne Corporate Engineering | Comments

Several years ago, MediaOne and its predecessor companies embarked on a nationwide program to upgrade its cable systems to "full service" hybrid fiber/coax (HFC) networks. In keeping with the fashion of the period, the nodes were sized according to a fixed number of passings: initially 2,000, then 1,000, and finally, 500 passings.


Compatibility lessons from the USB

January 31, 1999 7:00 pm | by Walter S. Ciciora, PH.D | Comments

I've repeatedly been asked two questions regarding the Decoder Interface. A "plug fest" is a gathering of manufacturers who have built prototypes of both sides of the Decoder Interface: TVs, VCRs, other devices with "cable-ready" TV tuners in them on the one side; and descramblers, digital television decoders, electronic program guide boxes, Web appliances and other "add-on" units on the other ...

Let the cities take over!

January 31, 1999 7:00 pm | by Roger Brown, Editor in Chief | Comments

The often-contentious relationship Tele-Communications Inc. has fostered with the governments of some of the largest cities in which it operates has sunk to a new low in recent weeks, thanks to AT&T's impending take-over of the monolithic MSO. At issue is access to the network TCI has struggled so hard to build.

Fiber hits the road

January 31, 1999 7:00 pm | by Craig Kuhl, Contributing Editor | Comments

Conventional wisdom suggests that once the top-10 multiple system operators (MSOs) begin slowing their "fiber-rich" plant rebuilds and upgrades-predicted to be in about seven years-the domestic cable fiber market will dry up. With 80 percent of cable's customers being serviced by those top-10 MSOs, and with that number sure to increase, fiber's domestic cable market certainly seems headed for a...


Emerging Technologies

January 31, 1999 7:00 pm | by CED Staff | Comments

… part II Interactive services Another half-day session honed in on what it means, technically, to offer an integrated suite of services to customers, in what AT&T calls "the whole broadband approach." Ralph Brown, chief architect of set-top systems for @Home Network, kicked off the session by noting that PC and TV application convergence will never reach 100 percent.


CES: The network is king

January 31, 1999 7:00 pm | by Fred Dawson, Contributing Editor | Comments

… part II There's no slam-dunk to achieving a one-content-stream-fits-all-networks mode, however. For example, when it comes to distributing content in multicast mode, which delivers multiple simultaneous streams to end users from one file, cable has a specific way of accommodating the technology over its shared distribution network, and suppliers of DSL systems have others, Compton noted.

The New Age, Millennium diet — High in fiber(2)

December 31, 1998 7:00 pm | by Thomas G. Robinson, Director of Regulatory Affairs and Technology Development, River Oaks Communications Corp. | Comments

Well, here we are, marching inexorably to the final days before Y2K and, for better or worse, to see if we really are "fully compliant." I wonder if these same questions will be pondered right before Y3K, or better yet, Y10K (the potential "five-digit" problem). Perhaps if we begin working on it now, the human race will survive.
