ISDN is a technology which enables the transmission of digital data over standard phone lines, and it was used for both voice calls and data transfers. ISDN, all-digital high-speed network provided by telephone carriers that allows voice and data to be carried over existing telephone circuits. International BRI circuits, commonly called ISDN-2 or ISDN Basic Access (IBA), use a different type of line coding that is called 4 Binary 3 Ternary (4B3T). The second implementation of ISDN is Primary Rate Interface (PRI). S/T and U interface models are available with 10 or 20 call appearances. The B channels carry the voice or data between the customer premises and the telco’s central office (CO), while the D channel is used for establishing connections and signaling. ISDN devices are called terminals. This technology creates two B-channels on the existing copper lines of 64 kbps each, along with a single 16 kbps D-channel for the phone line. The basic rate interface (BRl) specifies a digital pipe consisting two B channels of 64 Kbps each and one D channel of 16 Kbps. Basic Rate Interface (BRI): In the Integrated Services Digital Network ( ISDN ), there are two levels of service: the Basic Rate Interface (BRI), intended for the home and small enterprise, and the Primary Rate Interface (PRI), for larger users. Difference Between ISDN BRI and PRI Interface (With Table) Telecommunication has played a wider role in the development of this modern world.
