ISDN PRI

ISDN Primary Rate Interface (PRI)

Integrated Services for Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network.  There are several kinds of access interfaces to ISDN defined as Basic Rate Interface (BRI),Primary Rate Interface (PRI), Narrowband ISDN (N-ISDN), and Broadband ISDN (B-ISDN).

ISDN PRI gives you fast, flexible access to services such as direct inward and outward dialing, WATS, Toll-Free Service, and circuit-switched data. The Call-by-Call Service Selection and Individual Calling Line Identification capabilities offer a cost-effective, feature-rich method of local access for applications such as PBX trunking, Internet Service Provider access, host computer access, LAN-to-LAN connections, and videoconferencing.

PRI  is carried over an E1 (2048 kbit/s) in most parts of the world. An E1 is 30 'B' channels of 64 kbit/s, one 'D' channel of 64 kbit/s and a timing and alarm channel of 64 kbit/s.

PRI-ISDN is popular throughout the world, especially for connecting PBXs to PSTN.
