ATM data transmission systems based on N-ISDN

摘要

A novel approach for data transmission in N-ISDN (narrow band integrated services digital network) is proposed. This approach uses the ATM (asynchronous transfer mode) technology normally applied to B-ISDN (broad band ISDN) and provides high performance for the simultaneous transmission of several types of burst information using a single N-ISDN line. It will be compatible to B-ISDN in the future. In the paper, the proposed transmission model is first outlined, including its system description, the layer construction and the functional elements. Then, the transmission protocol is described in detail. Finally, a simulation system is realized, and the performance of the transmission system is confirmed by the simulation results which show the usefulness of the proposed data transmission mode.
