anti-kerchunking
Anti-kerchunking is a base station configuration that discourages users from
kerchunking.
B
balanced line A balanced line has two wires carrying equal and opposite signals. It is
typically used in a line-connected base station for connecting to the
despatcher console. The system interface identifies the balanced line in as
Rx+ and Rx-, and the balanced line out as Tx+ and Tx-.
BCD BCD (binary coded decimal) is a code in which a string of four binary digits
represents a decimal number.
BSS A BSS (base station system) is a subrack containing at least one TB8100 base
station.
C
Calibration Kit The TB8100 Calibration Kit is a utility for defining the switching ranges of
the receiver and the exciter and for flattening the receiver response across its
switching range. It can also be used to calibrate various parts of the reciter
and the PA circuitry.
CCDI2 CCDI2 (computer controlled data interface version 2) is a proprietary Tait
command protocol used between computer equipment and a Tait radio.
The TB8100 base station does not support CCDI2.
CCI CCI (computer controlled interface) is a proprietary Tait command protocol
used between computer equipment and a Tait radio. The TB8100 base
station supports CCI (refer to TN-947-AN).
channel A channel is:
■ A frequency pair (or just a single frequency in a simplex system).
■ A set of configuration information that defines the frequency pair and
other settings. Also referred to as a channel configuration. Generally,
‘channel’ has this meaning in the Service Kit.
channel profile A channel profile is a named set of configuration items relating to the base
station’s RF configuration, transmitter power output and power saving
modes. Like the signalling profile, it can be applied to any channel.
Together, these profiles define most configuration items.
channel spacing Channel spacing is the bandwidth that a channel nominally occupies. If a
base station has a channel spacing of 12.5 kHz, there must be a separation of
