BRI: Basic Rate Interface
Basic Rate Interface (BRI) is an ITU-T ISDN multipurpose user interface standard for simultaneous voice and data services provided over two 64-kb/s bearer channels and one 16-kb/s data channel (2B+D) access arrangement to each user location. The B channels are used for voice or user data, and the D channel is used for any combination of: data, control/signalling and X.25 packet networking. The two B channels can be bonded together giving a total data rate of 128 kbit/s. BRI is the kind of ISDN interface most likely to be found in residential service.
