Purpose: To provide detailed parameters for ordering and installing a PRI line. e PRI or Primary

and some long distance carriers are only delivering T-1 in this format. In the ISDN PRI format, it has
major benets – chiey the extra bandwidth and benets derived from the much faster out-of-band
signaling. PRI consists of 24 "bearer" or B-channels operating at 64,000 bits per second. One of the
B-channels is typically used to transmit signaling information for the other 23 channels. In Europe
and other regions, there are may be additional B-channels.
