GLOSSARY
agency - an agency is composed of multiple fleets. Units
can be programmed to initiate agency calls to
access multiple fleets. (Trunked Mode Only).
Base/Unit Operation - a programmed option used in some fleets so
units can only hear and talk to a base dispatch
unit, not to other mobiles or personals in the
group. In this mode of operation, when a unit in
a particular group is talking to the base dispatch
unit, all other mobile and personal radios in that
group will receive a "System Busy" tone if they
try to access the system. (Trunked Mode Only).
control channel - a radio channel in a trunked system that is used
to digitally communicate with the radios operat-
ing on the system when they are not engaged
in active voice communications.
conventional
channel - a radio channel (transmit/receive) that is allo-
cated for conventional (non-trunked) use and
may be manually selected by the operator.
conventional mode - communicating on radio channels allocated for
conventional use.
CCT - Carrier Controlled Timer - a programmable
timer that will disable a transmission if the timer
length is exceeded.
CG - Channel Guard - a method of controlling mute
with a tone or digital code.
Dynamic
Regrouping - Dynamic Regrouping is a feature which allows
the System Manager to dynamically program
new groups into selected radios. The System
Manager develops the regrouping plan and di-
rects the site controller to send each radio the
regroup information.
fleet - a fleet of users consists of multiple groups (sub-
fleets). Radios can be programmed to make
fleet calls to simultaneously access multiple
user groups. (Trunked Mode Only).
