Talk-around
Mode - Also referred to as "direct mode", talk-around
provides a direct unit-to-unit short range
communications link. It is intended to maintain
communications outside of the main system
coverage area.
Telephone
Inter-
Connect - This feature allows the user to initiate or receive
telephone calls through the radio if the system is
configured for this operation. (Trunked Mode Only)
Trunked
Group - A radio communications path shared by two or more
users.
Trunked
Operation - Trunked Operation refers to the use of a set of radio
frequency channels by multiple user groups. By
using high speed digital data the radio goes to an
unused channel when a call is initiated and will also
only respond to calls in the same user group. In this
way conversation privacy between user groups is
assured.
Trunked
Radio
System - A radio system in which a limited number of radio
channels is dynamically allocated to groups of
people for communication purposes.
Trunked
System - A set of one or more trunked groups.
T99 - Type 99 - a method of opening mute for selective
page operations using sequential tones.
Wide Area
Encode - A programmed option which ensures all system
scanning mobile and personal radios have time to
lock onto the call before the initiating unit is
allowed to talk.
Working
Channel - A radio channel (transmit/receive) that is
automatically assigned by the site controller for
voice or data communications.
