High Speed Internet Access - Broadband
Cable Modems and DSL (Digital Subscriber Link)

This is the new hot ticket, and EVERYBODY is getting it !! The lure of going from turtle-speed 56k, to 1 Mbps or better is just too much to turn down. Cable Companies are referred to as "MSO's" (Multi-Service Operators).
The Cable Modem and Cable TV Explosion
The Future: Cable vs DSL vs Wireless vs FTTC vs DBS
It was long thought that FTTC (Fiber To The Curb) would ultimately win out, once the funds had been raised to complete such a massively expensive project. But the other technologies have some important advantages:
The Worldwide, the base of cable modem subscribers is projected to more than double between last year and 2008, going from 32.8 million to 69.4 million, according to a study just released by IDC.
US Customers prefer Cable, but around the world, DSL has become the top choice. And by the end of the decade, wireless broadband will join DSL and cable as a major player in the market-share battle, according to new study by Visant Strategies. By 2009, Visant analysts project that wireless broadband will be growing faster than wire-line due to acceptance of technologies such as 802.16/WiMAX. Sales of WiMAX equipment will hit $2.2 billion in five years, Visant believes.
In the U.S., cable remains the top choice for broadband -- with about 50 percent more subscribers than DSL. By far, the majority of U.S. cable customers are residential users, although IDC's projections also call for about 2.5 million business cable modem subscribers by 2008. The DSL companies have been losing ground to the MSO's - rapidly. Cable technology can, in theory, achieve networking speeds of approximately 30 Mbps (using a 100 Mbps network interface card), whereas most forms of DSL cannot reach 10 Mbps. (VDSL is one variant of DSL that matches cable's performance, but it is not generally available.)
Cable Modem Troubleshooting
As with everything, there are often significant challenges in getting it to work properly. That is what these pages are here for . . . to help you get up and running.
See the "Getting it to Work" page for the actual steps, which include workarounds for the most common problems.

CableLabs® - Cable Modem Standards body
As with all standards, everybody wants to get into the game. ANSI, ITU-T, IEEE, IETF, etc - all feel they must be at the forefront of ALL standards. But in this case, CableLabs® ( http://www.cablelabs.com ) is leading the way. Their primary six interrelated initiatives are:
- DOCSIS® (Data Over Cable Service Interface Specification) is the
"glue" that makes the nation's cable modems work together - it is
a standard that defines interface requirements for cable modems involved in
high-speed data distribution over cable television system networks.
See the DOCSIS Presentation. MSOs
(Multi-Service Operators) and CableLabs require interoperability among
DOCSIS modems. While no CableLabs member company will be required to
purchase DOCSIS modems, the majority of modems purchased will be DOCSIS
certified. MSOs and CableLabs require vendors seeking product certification
to work with other vendors and CableLabs as part of the hot-staging for
- specifications for a "managed residential gateway", that will
offer a secure and convenient home networking solution when sharing a
broadband connection through a DOCSIS® cable modem.
- for delivering advanced, real-time multimedia services over two-way cable
plant. Built on top of the industry's highly successful cable modem
infrastructure, PacketCable networks use Internet protocol (IP) technology
to enable a wide range of multimedia services, such as IP telephony,
multimedia conferencing, interactive gaming, and general multimedia
OpenCableTM - OpenCable will provide a set of industry standards, which will help accomplish this goal via three key objectives to:
- creates an Internet-based electronic commerce tool to assist affiliated
computer makers, retail partners, and content providers in selling cable
services. G2B is the cable industry-wide tool that not only identifies what
cable services are available at an address but links affiliates directly
with the cable operator(s) so that services may actually be ordered. G2B
supports the deployment of DOCSIS modems as it brings together cable
operators with organizations wishing to promote high-speed data and other
digital cable services. Participating Affiliates benefit by becoming part of
an industry-wide solution. The G2B gateway portal provides a basic interface
for submitting a single address query and connecting with numerous cable
operators. G2B facilitates real-time service and pricing information from
the cable operators to the end-user in direct response to the service query.
Founded in 1988 by members of the cable television industry, Cable Television Laboratories, Inc. (CableLabs®) is a non-profit research and development consortium that is dedicated to pursuing new cable telecommunications technologies and to helping its cable operator members integrate those technical advancements into their business objectives.CableLabs serves the cable television industry by:
