What is BRI?

BRI stands for Basic Rate Interface. It is a digital telephone line service primarily used for ISDN (Integrated Services Digital Network). A BRI line consists of two 64 kbit/s 'B' channels for voice, data, and video, and one 16 kbit/s 'D' channel for signaling and control. It's commonly used for small to medium-sized businesses needing more lines than a single analog line can provide but less than a larger PRI (Primary Rate Interface).
