Glossary
VOX
Voice-operated transmit. A keying relay that is actuated by sound or voice
energy above a certain threshold and sensed by a connected acousto-electric
transducer. VOX uses voice energy to key a transmitter, eliminating the need for
push-to-talk operation.
VTG
virtual talk group. A VTG can contain any combination of channels, channel
groups, users, and user groups. A VTG can also contain other VTGs.
VTG template
Before becoming active, a VTG is in an inactive state as a VTG template. The
server stores VTG templates so that they can be automatically activated by a
policy or manually activated by a dispatcher. Also known as a preconfigured
VTG.
W
wavelength
The representation of a signal as a plot of amplitude versus time.
wideband channel
Channels that occupy more than 20 kHz.
