Primary Rate Interface (PRI) — consists of 23 B-channels and one D-channel (U.S.) or 30 B-channels and one D-channel (Europe). There are two types of ISDN: Basic Rate Interface (BRI) — consists of two 64-Kbps B-channels and one D-channel for transmitting control information. The B stands for bearer and D for data services. This basic service is intended to meet the needs of most individual user. The ISDN BRI services offer two B channels and one D channel. The first ISDN standard was defined in 1988 by the CCITT organziation, which is now the ITU-T (International Telegraph and Telephone Consultative Committee). The ISDN has several kinds of access interfaces such as − Basic Rate Interface (BRI) Primary Rate Interface (PRI) Narrowband ISDN; Broadband ISDN; Basic Rate Interface (BRI) The Basic Rate Interface or Basic Rate Access, simply called the ISDN BRI Connection uses the existing telephone infrastructure. Basic Rate Interface (BRI): two 64-kbit/s B channels and one 16-kbit/s D channel, intended for small enterprises and residential service. D or Delta channels:The D channels are intended for signalling and control, although it may also be used for data under some circumstances. Some switches limit B channels to the capacity 56Kb/s.
