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.

wavelength

The representation of a signal as a plot of amplitude versus time.

wideband channel

Channels that occupy more than 20 kHz.
