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.

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.
o
Virtual 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.
o
Virtual 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.
