PRI (Primary Rate Interface) / Local T1

An ISDN service that provides 23 64 Kbps B (Bearer) channels and one 64 Kbps D (Data) channel (23B+D), which is equivalent to the 24 channels of a T1 line. The advantage of the D channel is that it sends control signals that can dynamically allocate any number of B channels for different applications. For example, one channel can be used for voice, while another can be used for data, while six more can be used for a videoconferencing channel and so on.
