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 operating on the
system when they are not engaged in active voice
communications.
Conventional
Channel
-
a radio channel (transmit/receive) that is allocated for
conventional (non-trunked) use and may be manually
selected by the operator.
Conventional
Mode
-
communicating on radio channels allocated for
conventional use (i.e. conventional system).
CCT
-
Carrier Controlled Timer - a programmable timer that
will disable a transmission if the length is exceeded.
CG
-
Channel Guard - a method of controlling speaker mute
with a tone or digital code.
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)
Group Or
Subfleet
-
A group of users share the same program group
identification number in their mobile and personal
radios. All units in the same group will receive a
dispatch call placed by any one unit in the group.
(Trunked Mode only)
Group Scan
-
Programming that allows the radio to monitor many
groups simultaneously (multi-group decode),
permitting the user to both monitor and receive calls
from these groups. The radio may be programmed with
a scan hang time which causes the radio to remain on
the scanned group for a pre-programmed amount of
time, responding only to calls of a higher priority such
as priority scan group calls, individual calls, fleet calls,
agency calls, etc. When activity on the scan group
