Primary Rate Interface (PRI)
A standard ISDN frame format that specifies the protocol used between two or more
communications systems. PRI runs at 1.544 Mbps and, as used in North America, provides 23
64-kbps B-channels (voice or data) and one 64-kbps D-channel (signaling). The D-channel is the
24th channel of the interface and contains multiplexed signaling information for the other 23
channels.
