Type IIi A type of Trunking system composed of Fleets, Subfleets and
Talkgroups. This Trunking type supports both Type I and Type II
Handshaking. This Trunking type also allows Type I radios to
communicate with Type II radios on the same voice channel.
Universal ID A particular personality in a radio unit which is chosen as the one
whose Trunking identity will always be used to address this unit. In
this manner, a unit would respond to an individual call (Private Call,
Call Alert, Phone Interconnect, etc.) regardless of the current
personality chosen.
User Scan Scan type which is programmable through the front panel buttons on
the radio.
VCO Voltage-controlled oscillator; an oscillator whereby the frequency of
oscillation can be varied by changing a control voltage.

Prediction) Digital Operation, uses the VSELP digital signalling
protocol to encode and decode digital signals.
Voice Channel A Trunked repeater that is used to transmit and receive data and voice
from the radios on the system.
Voice Sel(ective)Call A signalling feature that gives radio users a level of privacy by allowing
them to choose who hears their messages. The users will be able to
direct their transmissions selectively: to a certain individual or to a
small group. Transmission will be heard through the speaker only if
that radio’s ID is sent. Users will therefore not be forced to listen to
transmission that does not pertain to them. This type of call leaves no
persisting visual nor audible indication.
Wide Area Call A call in a wide area coverage system which utilizes a voice channel in
all sites of the system.
Zone A collection of channels which have something in common.
