The primary rate interface (PRI) is really a telecommunications standard for carrying multiple DS0 voice and data transmissions between two physical sites. All data and voice channels are ISDN and operate at 64 kbit/s. ip phones system statesville nc and Japan use a T1 of 23 B channels just one D channel which matches a T1 line. Europe, Australia and a lot of most the world use the slightly higher capacity E1, which comprises of 30 B channels and one D sales channel.

Thus, a Primary Rate Interface user on a T1 line can have up to just one.544 Mbit/s service or up to two.048 Mbit/s service on an E1 line. PRI uses the Q.931 protocol over the D-channel. The B and D channel sizes are dependent regarding the Framing format of the T1 outlet. ie. Super Frame (SF) is a 56kb channel and the Extended Super Frame (ESF) is a 64kb procedure.
