The network normally associated with the future telecommunications systems based on asynchronous transfer mode (ATM).

broadband integrated services digital network. a single ISDN that can handle voice, data, and eventually video services

B-ISDN - Broadband Integrated Services Digital Network (See ISDN) A packet switching technique which uses packets of fixed length, resulting in lower processing and higher speeds. Also see ATM or Cell Relay

BISDN is both a concept and a set of services and developing standards for integrating digital transmission services in a broadband network of fiber optic and radio media. BISDN will encompass frame relay service for high speed data that can be sent in large bursts, the Fiber Distributed Data Interface (Fiber Distributed Data Interface), and the Synchronous Optical Network (Synchronous Optical Network). BISDN will support transmission from 2 Mbps up to much higher, but as yet unspecified, rates.
