What does high-speed data communication mean?
A current modem may be able to move information at 33.6 kilobits per second. An ISDN line can move information at 128 kilobits per second, or about four times as fast. It does this through the use of three “channels” on a single ISDN line. There are two B (bearer) channels that can move information at 64 kilobits per second each. By bonding the two channels into one large channel (something that can be done automatically, depending on your equipment), they can move information at 128 kilobits per second. There is also a D channel that carries information about the type of call being made. 3. What would I use ISDN for? The data side of ISDN could be used for anything a standard analog modem would be used for, i.e. Internet access, communicating with other computers, communicating with office networks, telecommuting (working from home instead of going to the office), except at a much faster rate, thus saving time. The voice capabilities of ISDN are similar to Centrex; call hold, three wa
