AN-PRC-152(C) - Harris RF Communications - Harris Corporation

ANDVT – Advanced Narrowband Digital Voice Terminal . A
COMSEC mode used in 5 kHz Narrowband SATCOM and
DAMA . Compatible with the KY-99, KY-99A, and KY-100
COMSEC encryption devices .
APCO – The Association of Public-Safety Communications
Officials-International (APCO) is the world’s largest organization
dedicated to public safety telecommunications .
APCO-25 – Project 25 (P25) or APCO-25 refer to a suite of
standards for digital radio communications for use by federal,
state/province and local public safety agencies in North America
to enable them to communicate with other agencies and
mutual aid response teams in emergencies . In this regard, P25
fills the same role as the European Tetra protocol, although
not interoperable with it .
ARQ – Automatic Repeat-reQuest, an error control method for
data transmission which makes use of acknowledgments and
timeouts to achieve reliable data transmission . An acknowledgment
is a message sent by the receiver to the transmitter
to indicate that it has correctly received a data frame . Usually,
when the transmitter does not receive the acknowledgment
before the timeout occurs (i .e . within a reasonable amount of
time after sending the data frame), it retransmits the frame
until it is either correctly received or the error persists beyond a
predetermined number of retransmissions .
COMSEC – Communications Security .
CTCSS or CDCSS – Continuous Tone or Continuous Digital
Coded Squelch System . Sub-audible tones used to prevent or
deny access into LMR repeaters and handheld radios (i .e ., FRS
radios) .
DS-101, DS-102 – Protocols used for loading encryption keys
into radio equipment from Data Transfer Devices (DTDs).
ECCM – Electronic Counter/Counter Measures . Refers to frequency
hopping capabilities (i .e ., SINCGARS and Havequick I/II) .
ECCM describes a variety of practices which attempt to reduce
or eliminate the effect of Electronic countermeasures (ECM)
on electronic sensors aboard vehicles, ships and aircraft and
weapons such as missiles . ECCM is also known as Electronic
Protective Measures (EPM), chiefly in Europe . In practice,
EPM often means resistance to jamming .
Glossary
AN/PRC-152(C) and AN/VRC-110
Applications and Accessories Handbook 27
ESIP – Enhanced SINCGARS Improvement Program . Added
additional data capabilities to the existing SINCGARS mode .
Features available for 30–87 .975 MHz LOS and SINCGARS
frequency hopping .
FASCINATOR – Type-1 COMSEC mode used by some Motorola
SABER II handheld radios .
Fill files – Now referred to as MISSION Plan files . Created by
the Falcon III Radio Programming Application that contains
radio net parameters and radio configuration settings . The file
is uploaded into the radio via USB connection then installed as
an active mission plan file .
GPS – Global Positioning System . Satellite system that is used
to obtain positioning and time information . Typically used with
the radio to load TOD for frequency hopping or HPW .
GTOD – Global Time-of-Day . Time of day synchronization
clock used by SINCGARS radio systems .
ICOM – SINCGARS fill mode from the DTD .
HALF DUPLEX – Refers to presets that use different frequencies
for transmit and receive (i .e ., SATCOM) .
HAVEQUICK – A frequency hopping mode used by the US Air
Force in the UHF range .
HPW – High-Performance Waveform . Satellite waveform that
can be used on both wideband and narrowband UHF satellites
. HPW offers high speed, reliable, error-free delivery of
data .
HUB – Hold Up Battery . It is recommended to replace the HUB
annually . HUB voltage level can be tested by conducting a BIT .
The HUB battery life can be extended by keeping the radio
main battery on at all times or radio connected to external
power .
