binary code
Electrical representation of quantities or symbols
expressed in the base-2 number system, which includes
zeros and ones.
bipolar 8 zero
substitution
bipolar signal
Digital signal in which pulses (ones) alternate between
positive and negative. See also
bipolar
violation
.
bipolar violation
Condition occurring when two positive or two negative
pulses are received in succession. See also
BIS
(Built-In Speakerphone) Part of the model name of some
analog multiline telephones.
bit
(binary digit) One unit of information in binary notation; it
can have one of two values, zero or one.
bit rate
Speed at which bits are transmitted, usually expressed in
bps
. Also called “data rate.” See also
blocking
Condition in which end-to-end connections cannot be
made on calls because of a full load on all possible
services and facilities. See also
BMI
(Broadcast Music Incorporated)
board
A module, for example, 100D or 408 MLX GS/LS, that
allows you to connect lines/trunks and extensions to the
communication system.
board assignment
SPM procedure for assigning line/trunk and extension
modules to slots on the control unit.
board renumbering
System programming procedure for renumbering boards
that have already been assigned to specific slots on the
control unit.
BRI
(Basic Rate Interface) Standard digital frame format that
specifies the protocol between the communication system
and a terminal. BRI runs at 192 Kbps and provides two
64-Kbps voice or B-channels and on 16-Kbps signaling or
D-channel per port. The remaining 48 Kbps are used for
framing and D-channel contention.
broadband
Transmission path having a bandwidth greater than a
voice-grade channel.
BTMI
(basic telephone modem interface)
