The first ISDN standard was defined in 1988 by the CCITT organziation, which is now the ITU-T (International Telegraph and Telephone Consultative Committee). ISDN, Integrated Services Digital Network, provides a number of significant advantages over analogue systems. Total data rate supported by BRI is 144 Kbps. The receiver side modem converts analog data to digital data. Much like its predecessor, the dial-up internet service, ISDN utilizes a … Integrated Services Digital Network (ISDN) was an earlier attempt to provide digital service via “copper pair,” the POTS (Plain Old Telephone Service) prevalent in homes and small offices around the world. It is available as a Primary Rate service which has 30 available channels or a Basic Rate service which has 2 channels. The current communications networks vary with the type of services, such as telephone networks, telex networks, and digital data transmission networks. Work on the standard began in 1980 at Bell Labs and was formally standardized in 1988 in the CCITT "Red Book". ISDN was designed to run over standard voice digital telephone systems already in place. ISDN (Integrated Services Digital Network) was introduced by CCITT in 1988. Although 128Kbps speed is more of standard in digital technology. There is one more listed below.
