ACU-1000
ACU-2000
JPS Interoperability devices with plug-in modules to interface various types of communications
devices: Radio, PSTN, VoIP, RoIP. The ACU-5000 interfaces will have similar functionality.
ARA-1
JPS device that provides a SIP interface to an individual radio or other four-wire device.
BSI
Bridging Systems Interface – A specification jointly developed by government and industry to
provide a standard interface for radio interoperability systems. The BSI is based on SIP and RTP
and allows bridging of radio nets between disparate interoperability systems.
COR
Carrier Operated Relay - A receiver signal that gives a positive indication a carrier or signal is
being received and the receiver is unsquelched. Same as
COS
.
COS
Carrier Operated Squelch - See
COR
.
COTS
Commercial Off-The-Shelf - A type of product that is readily available to the general public.
Does not conform to MIL-Specs.
Cross-
Connection
A link made between two communications systems interfaced to a single ACU-5000 chassis, or
between systems interfaced over a network to two or more ACU-5000 systems.
DTMF
Dual Tone Multi Frequency - The standard touch-tone telephone dialing method sends DTMF
audio characters over a PSTN line for control purposes. Can also be used with FM radio.
DSP
Digital Signal Processing (or Processor).
EIA
Electronic Industries Association.
Hangtime
A system with hangtime will remain in the transmit mode for the duration of the set hangtime
beyond the time indicated by any keying inputs. The hangtime prevents transmitter unkey during
brief pauses in the transmission.
iDEN
Integrated Digital Enhanced Network- Thus mobile telecommunication technology provides both
two-way radio connectivity and standard cellular telephone connectivity on the same network.
Key
To key a transmitter means to cause it to transmit.
LED
Light Emitting Diode.
LMR
Land Mobile Radio.
Mute
To quiet or inhibit audio.
NIST
National Institute of Standards and Technology - A United States government agency designed to
advance measurement science, standards, and technology.
NXU-2A
Network Extension Unit. A JPS device that interfaces a radio or other 4-wire device to other
communications devices over an IP network. An NXU-2A uses RoIP.
PBX
Private Branch Exchange. A telephone system that owned an operated by a private company (such
as a manufacturing business) rather than by a telephone company such as ATT.
PCB
Printed Circuit Board.
PSTN
Public Switched Telephone Network - The world's public circuit-switched telephone network
which provides connectivity to fixed-line and mobile telephones.
PTT
Push-to-Talk. An active PTT signal causes a transmitter to key.
Radio Net
A group of radio interfaces that are connected together. When any member of the net transmits
audio, the audio is retransmitted to be heard by all other members.
RJ-11
Registered Jack 11 - A physical interface for connecting wires, often used to terminate telephone
cables. It is a 6-position 4-contact (6P4C) connector. Although it can be used for other purposes,
this is commonly referred to as a standard phone jack or connector.
RJ-12
Registered Jack 12 - A physical interface for connecting wires; 6-position 6-contact (6P6C)
connector similar in shape to standard RJ-11 connectors. RJ-12 connectors will connect 6 wires.
RJ-45
Registered Jack 45 - A physical interface for connecting wires, often used to terminate Ethernet
cables. It is an 8-position 8-contact (8P8C) connector. Although it can be used for other purposes,
this is commonly referred to as a standard Ethernet jack or connector.
RoIP
TM
Radio over Internet Protocol. JPS proprietary protocol which sends voice plus radio control signals
over an IP network.
RX
Receiver or Receiving.
