AES / DES Encryption Options
NAC (Network Access Code) are programmable and are
typically used to control network access but may also be used to
steer repeater operations. NAC codes are used the same way
as an analog CTCSS tone (or DCS code). There are 4096
unique NAC codes.
For superior voice quality in narrow-band, digital, P25 mode of
operation our products use the AMBE+2™ Vocoder protocol
from DVSI, Inc.
Because our products are fully TIA/EIA 102 Series compliant,
you
are assured of broad compatibility within a wide range of P25
Digital Mode systems.
Talk Group IDs (TGIDs) provide for the logical grouping of radio
users into distinct organizations and can also be used to minimize
co-channel interference. There are more than 65,000 unique
TGID addresses.
Channels can be programmed for analog only, digital only or Mixed
Mode dual Analog/Digital operation. The radio will automatically
switch to the appropriate format when it receives a call. This
capability provides seamless switching between Analog and
Digital systems saves available channel programming capacity
and simplifies user operation of the unit.
Certain models feature Liquid Crystal Displays (LCD) and
provide visual indication of receive signal level (signal strength).
All models feature an audible indication of low receive signal
strength. When received signal strength falls to a level not
suitable for reliable communications, an alert tone will sound.
This feature is useful if the unit has no display or if it is difficult
for the user to see the display during normal operation.
P25 contains special provisions for Emergency Calling. When
an "Emergency" signal is received, the radio's "Busy" LED can
provide a very bright white blinking indication while the LCD can
show the Unit ID or Alpha Tag of the unit in distress...
Data Encryption Standard (DES) is an older format system
based on a 64 bit encryption algorithm...
Advanced Encryption Standard (AES) is a newer and more
robust system based on 256 bit algorithm. Encryption Keys
Multiple encryption keys can be stored in the unit as required.
The calling station will be identified either by their Alphanumeric
Tag (if defined in the Individual ID List), or by their ID number (if a Tag
is not defined).

The VX-920/970 Series provides up to five solid Watts of
transmitter power, for extended communications range. For
more localized applications, the power output may be
reduced to 2.5 W, 1 W, or 1/4 W, for enhanced battery life.
When programming radios for use in different jurisdictions,
the
VX-920/970 Series
portables may be set up, channel by
channel, for use in 12.5 kHz, 20 kHz, or 25 kHz channel
spacing environments. Deviation and bandwidth are
automatically set according to the configuration you choose.
For advanced network or fleet operations, a 5-Tone
Encoder-Decoder circuit is included in the VX-920/970
Series. An expensive option on many competing brands,
this included feature enhances operation without impacting
your budget.
The optional SRX-3 (UHF) and SRX-4 (VHF) Multi-Band
Receiver Units expand the versatility of the VX-920/970
Series significantly. For example, a UHF version of the VX920/970 Series may have the SRX-4 installed, expanding

When using the radio in a noisy environment, the Audio
Pitch Control adds aggressive equalization to the audio on
the incoming signal, allowing it to "punch" through the
ambient noise so the user will have a better chance of
understanding the incoming transmission.
To prevent interference to other users on busy channels, the
Busy Channel Lock-Out (BCLO) and Busy Tone Lock-Out
(BTLO) features prevent transmission by the portable if the
channel is occupied. And the Time-Out Timer (TOT) feature
will automatically cut of transmission if the programmed
maximum transmit time is exceeded.

To prevent use of the portable by an unauthorized operator
(in case of theft, non-payment of subscription, etc.), a
dispatch center can send a 5-Tone command to "Stun"
(temporary disabling) or "Kill" (permanent disabling) a unit. If
the "Stun" command has been sent, another 5-Tone
"Revive" command may also be sent, re-enabling operation
of the portable.
Any or all of the programmable keys may be assigned as
direct-
access one-touch keys for selecting important operating
The user may select, out of the dealer-programmed channel
list, one channel to be the "Home" channel, which may be
assigned to a "programmable" key for one-touch access to a
critically-important channel.
The ARTS™ feature is a "handshake" system that uses
DCS coding to confirm that two ARTS™-equipped units are
within communication range. If an "out of range" condition
develops, an alarm will sound and the communications
center can instruct the field unit to move to a better location
(or assistance to the field unit can be dispatched).
The large, easy-to-read display includes a 12-character dot
matrix that provides a wealth of information about the
operating channel, as well as various status icons.
Illuminated using Vertex Standard's renowned Omni-Glow™
back-lighting, the VX-929/924/
