NT6D70 SILC Line card
ISDN BRI
ISDN BRI consists of two 64Kb/s Bearer (B) channels and one 16Kb/s Data (D) channel. The
BRI interface is referred to as a 2B+D connection as well as a Digital Subscriber Loop
(DSL).
B-channels transmit user voice and data information at high speeds, while D-channels are
packet-switched links that carry call set-up, signaling and other user data across the
network.
One single DSL can carry two simultaneous voice or data conversations to the same or to
different locations. In either case, the D-channel can also be used for packet communication
to a third location simultaneously. The two B-channels can also be combined to transmit data
at uncompressed speeds of up to 128 Kbps.
A wide range of devices and telephone numbers can be associated with a single DSL to offer
equipment flexibility and reduce line, wiring, and installation costs.
