Integrated Services Digital Network (ISDN) is a set of communications standards for simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network. Basic Rate Interface (BRI, 2B+D, 2B1D) is an ISDN configuration intended primarily for use in subscriber lines similar to those that have long been used for plain old telephone service.
