Answer 2

PRI - Primary Rate Interface.

A primary rate interface or PRI is a provider-free system of communication that allows organizations to use a copper wire connection to transmit data, video, or files using a network architecture.

PRI systems allow for 23 B-channels on a single phone line. With a PRI-enabled communications solution, multiple users can have extensions and numbers on a single connection. Physically, PRI lines are comprised of two pairs of copper wires that provide duplex capability. Duplex capability allows secure data transmission from two of these wires to be received by the other two.

PRIs are integrated services digital networks (ISDN). There are two types of these, which include:

# Basic rate interfaces (BRI) solutions are intended for home and small business use. BRI systems have both a B- and D-channel, but unlike PRI lines, the B-channels can only house a single communication session.

# Primary rate interfaces are a more enterprise-ready solution thanks to the number of concurrent lines on the B-channel.
