ACU Interoperability Products
Raytheon JPS Communications’ ACU technology
provides the foundation to solve your communications interoperability
needs.
Our flagship product is the ACU-1000 which can interconnect up
to 24 devices. If you need a smaller solution, the ACU-T has
much the functionality of the ACU-1000 but in a smaller, more
portable
design. Coupled with our radio over internet protocol (RoIP)
/ voice over internet protocol (VoIP) products, the ACU-1000
can
be networked to provide hundreds of nodes for larger applications
and for wide area interoperability systems (WAIS).
Raytheon JPS Communications designs, manufactures and sells electronic
hardware and software products that enhance the effectiveness of
high frequency (HF) radio and land mobile radio (LMR) communications
systems. HF radio equipment is ideal for long distance communications,
and is used by the military and government agencies. LMR equipment
is better suited for short distance communications, and is used
by federal and local government agencies, such as police and fire
departments, railroads, commercial businesses and military groups
worldwide.
Our products include: intelligent
interconnects, RoIP/VoIP technology, radio/telephone interface
units, voice
modulation recognition systems,
voting products, HF pre/postselectors, switch matrices, transportable
products and noise reduction systems. These radio interconnect
products facilitate communications between two-way radios (HF and
VHF/UHF) and various other media, such as other radios, cellular,
landline telephone, NEXTEL and SATCOM. JPS’ signature product,
the ACU-1000 Intelligent Interconnect System, provides interoperability
between multiple radio systems operating on different frequencies
to simplify communications for public safety, military and railway
as well as federal and local governments.
Applications
Miner Electronics can serve your operability and
interoperability needs with many system configurations. Whether
your application
calls for
a fixed site installation or a small, transportable one, we can
support you with the right system at the right budget. Our application
categories are:
Interoperability Applications
- ACU-1000: All of our interoperability products have a common
building block, our time-tested, proven, unsurpassed ACU-1000
technology.
- Fixed Site: If your
application calls for a comprehensive interoperability system
in a permanent
installation, this is the
solution we recommend.
- Transportable: If your
interoperability needs call for fast response, smaller size,
in remote locations,
a transportable
system is the way to go. Our TRP family of products is a good
example. They offer superior versatility and fast installation.
- Mobile: JPS offers
mobile configurations that feature fully interoperable communications
systems in a
van, bus, or other
vehicle of your choosing. We can help you design the mobile
configuration that best meets the needs in your areas of geographic
coverage.
- Wide Area Interoperability
System (WAIS): JPS also supports your wide area communications
needs,
including intra-state, state-to-state,
and coast to coast interconnectivity.
Operability Applications
- Voter Systems: We offer a number
of solutions to achieve the best signals for transmitting
and receiving your communications.
Our proven voter systems are a good example.
VoIP Technology
VoIP stands for Voice over Internet Protocol, which is a means
of digitizing voice signals and sending them over a digital network.
The digital network can be a LAN (Local Area Network), WAN (Wide
Area Network), or the Internet itself. The NXU-2 and NXU-X embodies
this VoIP technology in a way that enables communications radios
to be interconnected across the room or around the world. The
PortaLink is an extension of the NXU-2, incorporating it with
a wireless network to allow a radio’s voice and RS-232
at a remote location to be linked to an ACU-1000.
Radio/Telephone Interface Units
The phone patch family uses a digital signal processor (DSP) to
dynamically provide a broadband hybrid null, thus eliminating
VOX falsing and other problems that are characteristic of other
phone patches.
VMR-12A Voice Modulation Recognition Unit
The VMR-12 Voice Modulation Recognition Unit
is packaged in a 19 inch EIA standard rack-mounted Eurocard cage.
A Power Supply
Module and up to twelve VMM-2 Voice Modulation Recognition Modules
are plugged into the card cage backplane. Each VMM-2 Module provides
the next generation of reliable speech detection capability in
noisy audio signals by using state of the art Digital Signal
Processing (DSP) techniques. Each module’s DSP is capable
of accurately detecting speech, including the elusive first syllable,
in any of the following audio sources: in audio received by a
radio; in a noisy phone line; in a tape recording made under
adverse conditions; or in an intercom system being used in a
high ambient background noise environment.
Voting Products
The SNV selects the input channel with the best quality audio
based on the DSP computed signal-to-noise ratio of the incoming
audio
signals.
PPS-100 Pre/Postselector
The PPS-100 Pre/Postselector permits operation
of co-located receivers and transmitters on frequencies separated
by as little
as 10%.
When used with receivers, the unit functions as a preselector,
providing an additional front end selectivity stage. This reduces
the receiver desensitization and overload that would normally
occur in the presence of strong adjacent RF transmissions.
The unit is used as a postselector with transmitters. It rejects
spurious outputs and broadband noise in the transmit signal
before
it reaches the power amplifier, thereby limiting interference
to neighboring receivers. The PPS-100 performs both functions
with a transceiver; it follows the radio’s key line and
switches between the preselector and postselector modes.
MTX-1616 Audio/Digital Switch Matrix
Our’ MTX-1616 Audio/Digital
Switch Matrix provides a flexible single-unit answer to the need
for different
switching circuits for each of the many configurations. The unit
has been designed to switch both audio controls and control signals
simultaneously; the standard configuration contains both a 16x16
audio switch matrix and a 16x8 delay matrix.
TRP-1000 Transportable Radio Interconnect
The TRP-1000 Transportable Radio Interconnect
System provides radio interoperability during missions requiring
communications
between
diverse organizations using different radios and different frequencies.
The system package consists of one or more transportable cases
and includes multiple radios pre-wired to JPS Communications’ ACU-1000
Intelligent Interconnect Unit. The radios, which cover all frequency
bands can be cross-connected through the ACU-1000.
NRU-600 DSP Noise Reduction Unit
The NRU-600 is an advanced audio signal processor that provides
maximum flexibility to eliminate or reduce most types of interference
from voice, CW and data transmissions. The unit uses a high speed
Digital Signal Processor (DSP) to provide simultaneous bandpass
filtering, noise reduction and multiple tone/heterodyne removal.
An automatic Notch filter removes multiple heterodynes from tune-ups,
adjacent channel carriers, CW, RTTY, or similar signals without
interfering with voice signals when a voice bandwidth has been
selected. The notch filter operates in 5 milliseconds or less.
Two noise reduction algorithms are provided in the NRU-600: an
FD (Frequency Domain) algorithm and a TD (Time Domain) algorithm;
to give the operator the best audio noise reduction possible.
