ATM makes B-ISDN a reality. The Integrated services Digital Network (ISDN) evolved during the 80's. It carried a basic channel that could operate at 64kbps (B-channel) and combinations of this and others (D-channels) formed the basis of communication on the network. In the new B-ISDN world, this is supposed to supply data, voice and other communication services over a common network with a wide range of data speeds. To understand a lot of the terminology in ATM-land, it is necessary to understand the B-ISDN Reference Model. Just as the ISO seve ....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 .

The most important development in the computer communications industry in the 1990s is the evolution of the integrated services digital network (ISDN) and broadband ISDN (B-ISDN). The ISDN and B-ISDN have had a dramatic impact on the planning and deployment of intelligent digital networks providing integrated services for voice, data and video. Further, the work on the ISDN and B-ISDN standards has led to the development of two major new networking technologies; frame relay and asynchronous transfer mode (ATM). Frame relay and ATM have become t ....etc

Modems
The modern telephone system is designed to carry the sound of a human voice talking normally. The engineers save money by cutting out the high a low pitch sounds that occur only in music, or sounds that last for a very short period of time. Modems convert data into sound so that it can be sent through the phone system. Just as the telegraph sent data by alternating dots and dashes, the earliest modems sent data by alternating the sound on a phone between two tones. However, modern modems move much larger amounts of data by sending combi ....etc
