Originally published in two editions in Japanese by Ohmsha, one of Japan's most highly regarded authorities on broadband ISDN. This English edition is now thoroughly revised and updated. It is a study of broadband ISDN (Integrated Systems Digital Networking) which is the technology that provides broadband communications services like multimedia and electronic trading networks (ETNs). The book gives a distinct perspective on the impact of the evolution of ATM on B-ISDN.
