barrier code
A security code used with the Remote Access feature to prevent unauthorized access to the system.
Basic Rate Interface (BRI)
A standard ISDN frame format that specifies the protocol used between two or more communications
systems. BRI runs at 192 Mbps and provides two 64-kbps B-channels (voice and data) and one
16-kbps D-channel (signaling). The D-channel connects, monitors, and disconnects all calls. It also
can carry low-speed packet data at 9.6 kbps.
baud
A unit of transmission rate equal to the number of signal events per second. See also
bit rate
and
bits
per second (bps)

BCC
See
Bearer capability class (BCC)

BCD
Binary coded decimal

Bearer capability class (BCC)
Code that identifies the type of a call (for example, voice and different types of data). Determination
of BCC is based on the caller’s characteristics for non-ISDN endpoints and on the Bearer Capability
and Low-Layer Compatibility Information Elements of an ISDN endpoint. Current BCCs are 0
(voice-grade data and voice), 1 (DMI mode 1, 56 kbps data transmission), 2 (DMI mode 2,
synchronous/asynchronous data transmission up to 19.2 kbps) 3 (DMI mode 3, 64 kbps circuit/packet
data transmission), 4 (DMI mode 0, 64 kbps synchronous data), 5 (temporary signaling connection,
and 6 (wideband call, 128–1984 kbps synchronous data).
BER
Bit error rate
BHCC
Busy-hour call completions
bit (binary digit)
One unit of information in binary notation, having two possible values: 0 or 1.
bits per second (bps)
The number of binary units of information that are transmitted or received per second. See also
baud
and
bit rate
.
bit rate
The speed at which bits are transmitted, usually expressed in bits per second. Also called data rate.
See also
baud
and
bits per second (bps)

BLF
Busy Lamp Field
BN
Billing number
BOS
Bit-oriented signaling
