Automated VR Activation. VR Option which permits automated
activation of the VR by either using a VIP input on the MSU CH /
DEK or a pin on the VR Auxiliary cable. Requires external logic /
switch, not provided with the VR hardware.
To prevent unauthorized access for Conventional ‘DVRS Enabled’
PSU, Authentication key can be loaded on the authentication
capable ‘DVRS Enabled’ PSU.
When enabled, causes the MSU to block usage of the same
frequency band as the VR while the VR is active. Enabled by default
when no in-band filter is present.
Busy Lockout – dynamic voting phase (follows the static Primary /
Secondary phase) of the VR simulcast prevention algorithm.
A group of characteristics, such as transmit / receive frequency pairs,
radio parameters, encryption encoding etc.
Tone Private-Line (PL) or Digital Private-Line (DPL). Used on
conventional channels for signal validation.
Refers to radio-to-radio communications, sometimes through a base
station repeater or vehicular repeater.
An individual who has radio system management duties.
VR personality file saved as file_name.DPD.
A continuous sub-audible data signal transmitted with the carrier.
See Coded Squelch.
Digital Vehicular Repeater.
Determines the communication exchange capabilities between
System Users and Local Portable Users; Can be set to OFF, LOCAL
or SYSTEM.
When a Vehicular Repeater (VR) is interfaced with an MSU, the
complete equipment package is referred to as a Digital Vehicular
Repeater System (DVRS).
