BRI (Basic Rate Interface)
Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM.
The basic rate interface is the minimal service obtainable for ISDN (Integrated Services Digital Network). ISDN is a digital phone service that is meant to replace the traditional analog phone system.
BRI consists of two 64-Kbit/sec B channels and one 16-Kbit/sec D channel. Each B channel can carry a single digitized voice call or can be used as a data channel. The B channels can also be combined to form a single 128-Kbit/sec data channel. The D channel is used for call establishment and other signaling.
