ISDN definition

ISDN refers to a digital circuit switched network service. Basic Rate ISDN (BRI) provides for channelized (two (2) bearer and one (1) data) end- to-end digital connectivity for the transmission of voice or data on either or both bearer channels and packet data on the data channel. Primary Rate ISDN (PRI) provides for twenty-three (23) bearer channels and one (1) data channel. For BRI, the bearer channels operate at 64 Kbps and the data channel at 16 Kbps. For PRI, all twenty-four (24) channels operate at 64 Kbps or
