(areas) with one another is known as the backbone.
Basic Rate Interface
The Basic Rate Interface is a network connection to the ISDN. This
type of connection is often abbreviated to BRI. A basic rate interface
includes two basic channels (B channels) each with 64 kbps and
one control and signalling channel (D channel) with 16 kbps. There
are two operating modes for the Basic Rate Interface: Point-to-point
ISDN and Point-to-multipoint The Primary Rate Interface (PRI) is
used with larger installations.
