Definition of BRI- Basic Rate Interface

The Basic Rate Interface or Basic Rate Access is the ISDN configuration designed explicitly for subscriber line applications close to those used for voice service for many years. Furthermore, an ISDN BRI connection may use such the current telecommunications infrastructure of a company. The architecture of BRI includes 2 (bear) databases (B) in 64 kbit / s and 1 (D) channel (D) in 16 kbit / s in each architecture. The B-channels are for speech or user data, and the D-channel is used for all data, control/signal, and networking packets. Channel bonding with a combined data rate of 128 kbit / s is necessary to aggregate the 2 B channels. The BRI ISDN service (ISDN PABX) is typically deployed in many countries for residential or small business service purposes.
