Broadband ISDN (B-ISDN) is a second generation of the ISDN. Integrated Services Digital Network (ISDN) Patrick Okot . 6 . Basic Rate • Access to the network is called Basic Rate Access (BRA). The entry level interface to ISDN is the Basic Rate Interface (BRI), a 128 kbit/s service delivered over a pair of standard telephone copper wires. The 144 kbit/s overall payload rate is divided into two 64 kbit/s bearer channels ('B' channels) and one 16 kbit/s signaling channel ('D' channel or data channel). ISDN is a telecommunications technology that enables the transmission of digital data over standard phone lines. The main feature of ISDN is that it can integrate speech and data on the same lines, which were not available in the classic telephone system. Figure 4.
