BRI Trunk
Basic Rate Interface (BRI, 2B+D, 2B1D) is an Integrated Services Digital
Network (ISDN) configuration intended primarily for use in subscriber lines
similar to those that have long been used for plain old telephone service. The
BRI configuration provides 2 bearer channels (B channels) at 64 kbit/s each and
1 data channel (D channel) at 16 kbit/s. 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.
