ARA-1TM
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 isbeing
received and the receiver is unsquelched. Same as COS.
COS
Carrier Operated Squelch. See COR.
Cross-
Connection
A link made between two communications systems (e.g.: radio, SIP, etc.) interfaced by an
interoperability gateway. This could include only systems local to the gateway, or be a “wide-area”
system that brings in remote systems via a network.
DHCP
Dynamic Host Control. IP network protocol that assigns IP addresses and network configuration
parameters a needed in order to avoid assigning static (unchanging) IP addresses.
Dispatch
Capability for a designated dispatcher to have one-way monitoring of and two-way private
conversations with audio source systems (channels) outside of interoperability net activity.
DNS
Domain Name System. Essential component of internet functionality; DNS is a system for naming
system computers, services, or other resources connected to the internet or a private network.
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).
Hangtime
Sometimes called VOX Hangtime, Receive Hangtime, or Transmit Hangtime, a hangtime causes a
device to maintain the effect of audio presence for a brief period even without the actual presence
of audio. Hangtime is often used to prevent brief pauses in input audio from unkeying an attached
transmitter during the pauses. It may be applied to input audio to provide consistent audio to
multiple outputs (VOX Hangtime or Receive Hangtime) or, theoretically, applied to an output
audio to solely effect a single output (Transmit Hangtime).
Key
To key a transmitter means to cause it to transmit.
LAN
Local Area Network. Connects local devices in the same geographic location, such as a building.
LMR
Land Mobile Radio.
Monitor
Capability on ACU-Z1 and Z2 Controllers (and classic JPS interoperability products) for a channel
to monitor/listen to one or more other channels, independently of dispatch.
NAT
Network Address Translation. A mechanism that translates and hides internal LAN IP addresses
from the outside world, which only sees a WAN IP address.
NXU-2BTM
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-2B uses RoIP. (Previous version NXU-2A).
PAT

by a NAT router that allows internal hosts to use the same port numbers but expose different ports
to the WAN.
PBX
Private Branch Exchange. A telephone system owned and 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.
RoIP

URI
Uniform Resource Identifier. Unambiguous string of characters that identify a resource on a
network. (E.g. URL (Uniform Resource Locator) or web address.)
VMR
Voice Modulation Recognition. A form of audio presence detection based on the presence of
human speech and notably not by tones, noise, or other non-speech audio. It is typically used as a
gating mechanism for audio –when speech is detected by VMR, this allows the speech audio to
flow into or out of a device. VMR is particularly useful with noisy audio signals such as HF because
VMR will ignore most static and white noise.
VoIP
Voice Over Internet Protocol. Protocol for delivering voice communications over IP networks.
Most network-phone providers (such as Vonage), use VoIP.
VOX
Voice Operated Xmit (Transmit), or Voice Operated Switch. A form of audio presence detection
based on sound presence and volume. It is typically used as a gating mechanism for audio –when
sound exceeds a VOX threshold, this allows the audio to flow into or out of a device. The sound is
not restricted to voice only.
WAN
Wide Area Network. Connects local devices and LANs from multiple locations. A WAN may be
limited to a multi-site enterprise, for example, or accessible to the public (e.g. the internet).

Interoperability Now 1-1 Z2C Installation and Operation Manual
1Overview
The Z2 Controller creates a scalable interoperability system that is easily managed via its
straightforward, browser-based Graphical User Interface (GUI). Tying together the wide range
of audio communications devices remotely interfaced to it, the Z2 Controller enables audio
sharing with all JPS RoIP (Radio over IP) products, such as the NXU‑2B, the ACU-2000, the
ACU-M, etc., as well as with JPS’ new Z series of products, including the RSP-Z2 and the
ACU‑Z1. Features like simplified dispatch capability, monitoring by non-dispatch channels, and
IP recorder integration provide enhanced functionality, making the Z2 Controller an adaptable
solution to a diverse array of interoperability and communications uses.
1.1 Scope
This Installation and Operations Manual provides a description, specifications, and configuration
and operating instructions for the JPS Interoperability Solutions' Z2 Controller.
This section provides some essential background information that will assist in understanding
the capabilities of the Z2 Controller unit and the basic elements that make up an interoperability
system that it controls. The Z2 Controller will also be referred to as the Z2CTM.

Z2 Controller Operations Manual
Z2C Installation and Operation Manual 1-2 Interoperability Now
1.1.1 Important Definitions:
COR: A signal that indicates when a radio (or other type of communications
device, such as an ACU ‑ Z1 or an RSP-Z2) is receiving a valid audio signal.
PTT: A signal that tells a radio (or other communications device) to transmit the
audio signal being sent to it.
Full-Duplex Communication System: Users can simultaneously talk to and
listen (for example, a standard telephone call).
Simplex or Half-Duplex Communication System: Only one system user can
be heard at a time.
Interoperability Net: Communications link consisting of disparate devices (such
as radios of different frequencies, telephones, VoIP phones, etc.) connected
together, similar to a conference call.
The following paradigms are essential in understanding the basic operation of an interoperability
system.
•If multiple communications devices are engaged in an interoperability net, whenever one
device detects active COR (valid audio input), that audio, along with a PTT signal, is sent
to all other devices in the net to be transmitted.
•If any device in an interoperability net is half duplex (such as are almost all radio
systems), then all communications must be half duplex.
1.2 Z2 Controller Basic Overview
Using the Z2 Controller, Operators easily configure and manage up to 80 remote virtual
streaming channels and an optional USB headset using the intuitive GUI, which provides the
following functions:
•Easily create and manage interoperability nets that cross-connect various voice
communications systems that are interfaced to the Z2 Controller. Once they are
connected, an Operator simply manages all resources using the Z2 Controller GUI.
oVirtual JPS Bridge channels offer a means for remote devices, such as RSP‑Z2
Dual-Channel Interoperability Gateways and MCC Desktop Consoles, to
connect/stream audio to the Z2 Controller to expand interoperability coverage and
functionality. Optional encryption licenses are available for added security.
oVirtual JPS RoIP channels provide a mechanism for streaming audio from a
remote source –such as a radio connected to an NXU‑2B or a DSP‑2 card on an
ACU 2000 –to the Z2 Controller using JPS RoIP. They may also be used to
interface to a Push-to-Talk application such as JPS VIA. Optional encryption
licenses are available for added security.

•Use the versatile Dispatch feature for one- and two-way communications.
oA Dispatcher can place any number of the resources interfaced to the Z2
Controller into an easy-to-use Dispatch Area for one-way listening (monitoring)
or two-way communications (dispatch).
oIt does not matter whether these resources are concurrently engaged in an
interoperability net.
•Monitor one or more channels independent of net/Dispatch activity.
oMultiple resources can be set up to monitor other channels.
oChannels may be monitored by more than one Monitoring resource.
•Record all channels within a net, or within the Dispatch area. This provides system
operators the ability to stream conversations directly to an IP recorder for non-evidentiary
recordkeeping and playback.
•Manage users/permission, set up and verify Z2 Controller network configuration, and
configure channels easily using the browser-based GUI and its built-in help text.
1.2.1 Interoperability and Dispatch
The main purposes of the Z2C are to create interoperability nets that link multiple voice
communications systems together, and/or to Dispatch to those systems.
The following block diagram shows a small sample interoperability system that will be used to
illustrate various Z2C system functions.

Z2 Controller Operations Manual
Z2C Installation and Operation Manual 1-4 Interoperability Now
The example system has eight different voice communications channels: Five are different radio
bands/frequencies, another is a SIP Phone, and the remaining two consist of a pair of JPS VIA
PTT over Cellular Talkgroups. These channels are all interfaced to the system via four RSP-Z2
units using Bridge channels and one NXU-2B that uses JPS RoIP. Note that each of the JPS VIA
Talk Groups requires a dedicated RSP-Z2 channel, which is interfaced to the JPS VIA server and
adapts the JPS VIA channel into a format recognizable to the Z2C.
Each of the channels is configured on the Z2C, which can accept connections on up to 80 virtual
streaming channels, using JPS Bridge or JPS RoIP data stream protocols. By setting up channels
on the Z2C to accept these connections, users can manage streaming audio to and from connected
remote resources. (E.g. Putting channels in nets, dispatching to/from channels).
•JPS Bridge channels are available on newer JPS products, such as this unit as well as
other Z-series products, and on some third-party devices, such as the MCC Desktop
Console, that have implemented the JPS Bridge Channel Protocol.
•JPS RoIP (Radio over IP) is a JPS proprietary protocol that sends voice plus radio control
signals over an IP network. With only a few exceptions, JPS RoIP channels are available
on most JPS radio interoperability gateway products.
•While JPS’ newer products have both JPS Bridge and JPS RoIP streaming channels, it is
best to use Bridge channels as they carry additional helpful data such as Audio Priority.
Furthermore, JPS Bridge channels support streamlined integration with other JPS systems
and with select third-party products.
Operators browse to the Z2C GUI to create and dissolve any interoperability nets. Its audio
engine handles all audio mixing.
