Z2 Controller Configuration
5.1
Virtual JPS Bridge and RoIP Channels
This section of the Z2 Controller Manual explains how to configure channels on the Z2C. Once
your channels are configured, refer to Section 6
Z2C’s Dispatch, Net, Monitoring, and Recording functions using the Z2C Graphical User
Interface (GUI).
5.1.1
Virtual Channels Stream Audio to the Z2C from Other Devices
Before proceeding, it may be helpful to recall the relationships between the devices and the
systems we are discussing. In brief: disparate communications systems (radio, SIP, PTToC, RTP,
etc.) connect to audio streaming devices/gateways (RSP-Z2s, ACU-Z1s, NXU-2Bs, etc.), which
link to the Z2 Controller using virtual JPS Bridge or JPS RoIP channels. The Z2C GUI
consolidates interoperability nets, dispatching, monitoring, and recording management, and the
Z2C audio engine handles all audio mixing.
Let’s look at an example system that 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 disparate audio systems are all interfaced
to the Z2 Controller via four RSP-Z2 units using JPS Bridge channels and one NXU-2B that uses
JPS RoIP. Refer to the diagram on the next page:
•
The eight (8) channels referenced are configured on the Z2 Controller. Each of the eight
channels is a streaming channel, meaning no hardware is attached directly to the Z2C.
•
Four (4) of the radios are being streamed from RSP-Z2 units. The RSP-Z2, which is
capable of streaming two independent channels, is converting the analog radio signal
coming from the attached donor radio to a JPS Bridge channel that is directed at the Z2C.
•
One (1) of the radios is being streamed from an NXU-2B. In this case, the analog radio
signal coming from the attached donor radio is converted to a JPS RoIP stream directed
at the Z2C.
•
The SIP channel is already a virtual channel. It is converted to a JPS Bridge type carrier
channel on the RSP-Z2 and streamed to the Z2C.
•
Each of the JPS VIA PTToC Talkgroups also 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.
In summary, the Z2C manages audio streams by providing a convenient hub where the audio
those streams carry can be easily put into communication nets, dispatched to, monitored, and
recorded using the browser-based GUI. Once the remote device – RSP-Z2 or NXU-2B for
example – is configured properly, the corresponding JPS Bridge or RoIP channels on the Z2C
