B-ISDN

(Broadband-ISDN) A framework for advanced telecommunications from the ITU. Introduced in 1988 as an extension to ISDN, it was designed to provide a blueprint to integrate data, voice and video in the 21st century. B-ISDN specifies the use of ATM for switching and SONET for high-speed links. See ATM and SONET.
