Micro Controllers
(Cable Modems)


ABSTRACT

The present need to access internet in homes, offices, companies
etc in affordable way results in selection of efficient technology and
as a result cable modems are used. Cable modem technology brings high-
speed broadband networking to desired places through cable television
lines. Cable modems are devices that allow high-speed access to
information at a distant server may it be Internet server or video on
demand server, via a cable television ....etc

Cable Television Laboratories Inc., and its associates have prepared a series of interface specifications known Data over Cable System (DOCSIS) that permit the early definition, design, development and deployment of data-over-cable systems on a uniform, consistent, open, non-proprietary, multi-vendor interoperable basis. This would also back up the cable operators are interested in deploying high-speed data communications systems on cable television systems.

This service allows transparent bi-directional transfer of Internet Protocol (IP) tr ....etc

Definition
Using an ordinary phone for most people is a common daily occurrence as is listening to your favorite CD containing the digitally recorded music. It is only a small extension to these technologies in having your voice transmitted in data packets. The transmission of voice in the phone network was done originally using an analog signal but this has been replaced in much of the world by digital networks. Although many of our phones are still analog, the network that carries that voice has become digital.

In todays phone networks, t ....etc

ABSTRACT
Voice (and fax) service over cable networks is known as cable-based Internet Protocol (IP) telephony. Cable based IP telephony holds the promise of simplified and consolidated communication services provided by a single carrier at a lower cost than consumers currently to pay to separate Internet, television and telephony service providers. Cable operators have already worked through the technical challenges of providing Internet service and optimizing the existing bandwidth in their cable plants to deliver high ....etc

A modem used to connect a computer to a cable TV service that provides Internet access. Cable modems can dramatically increase the bandwidth between the user's computer and the Internet service provider. Download speeds have reached 6 Mbps and beyond, but the connection is asynchronous. In order to prevent users with lower-cost cable access from hosting high-traffic Web servers, the upload speed is considerably slower, from 10 to 20 times slower. Cable operators also routinely change IP addresses assigned to users to prevent Web hosting .

Fast Internet access is growing from a convenience into a necessity in all aspects of our daily lives. Unfortunately, this has been held back by the high expenses of wiring infrastructure essential to deliver such high-speed internet access especially to private homes, small offices and rural areas, where the installation of any kind of new wires tilts the scales of the economic feasibility to a non-profitable state. This problem is known as the ?last mile problem? which has been an active area of research throughout research community.
