Integrated Services Digital Network Primary Rate Interface (ISDN-PRI)
The interface between multiple communications systems that in North America includes 24 64-kbps
channels, corresponding to the North American digital signal level-1 (DS1) standard rate of 1.544
Mbps. The most common arrangement of channels in ISDN-PRI is 23 64-kbps B-channels for
transmitting voice and data and 1 64-kbps D-channel for transmitting associated B-channel call
control and out-of-band signaling information. With nonfacility-associated signaling (NFAS),
ISDN-PRI can include 24 B-channels and no D-channel. See also
