GLOSSARY
Agency
- An agency is composed of multiple fleets. Units can be
p
rogrammed 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 othe
r
mobiles or personals in the group. In this mode o
f
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 fo
r
conventional (non-trunked) use and may be manually
selected by the operator.
Conventional
Mode
-
communicating on radio channels allocated fo
r
conventional use (i.e. conventional system).
CCT
- Carrier Controlled Timer - a programmable timer tha
t
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),
p
ermitting 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 o
f
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
