This incredibly versatile analog/VoIP gateway enables audio patching between local radio and IP-based resources such as JPS RoIP or JPS Bridge streams, SIP devices, Push-to-Talk over Cellular (PoC) applications, and more.

Incorporating the JPS suite of radio interface algorithms and the ability to use JPS’ large catalog of radio interface cables, the RSP-Z2™ embodies all of the customer-friendly features and benefits you’ve come to expect from JPS.

For Any Gateway: from Simple to Complex

The resources associated with the two radio connectors on the RSP-Z2 may be configured as local radios or they may be configured for IP-based communications. Two more resources on the RSP-Z2 are dedicated to IP-based communications. Unique features provide superior radio system connectivity including our Adaptive Transmit Delay (US Pat. 10630846) for a vastly superior trunked radio interface, as well as JPS’ continued attention to smooth integration with all types of half-duplex devices. On the IP side, a growing list of connectivity to different types of audio streaming services ensures the complex challenges of patching these systems to radios or each other is handled with ease.

Highly capable on its own, the RSP-Z2 integrates seamlessly with the Z-Series Controller to create an expandable, robust wide area interoperability system. Enhancing the wide area functionality, when these devices are used together, JPS Talkpaths are automatically created between RSP-Z2s and the Z-Series Controller as needed, providing clean, on-demand audio routing and connectivity.

Optional HC-128 and AES-256 encryption can be licensed on JPS Z-Series devices for JPS Talkpaths, JPS Bridge and JPS RoIP audio.

Access from Anywhere

The dynamic patching capability of the RSP-Z2 can be controlled and its audio flow monitored via the unit’s web-based graphical user interface. Since the user interface is browser-based, it can be accessed from anywhere using a modern computer, smartphone, or tablet.

When an RSP-Z2 is made part of a wide area system managed by a Z-Series Controller, all its resources immediately display on the Z-Series Controller user interface where they can be managed, reconfigured, etc. by the Z-Series Controller operator. Meanwhile, the RSP-Z2 user interface continues to reflect its own resources, as well as status and connection indicators, including JPS Talkpaths for when a resource is put into a net with a resource from another system.

Net Presets or Custom Mode

Convenient net presets simplify some of the most common standalone configurations. In Independent Passthrough, the RSP-Z2 acts as a pair of independent IP data streams. In this mode, the unit behaves similarly to a two-channel version of the popular JPS NXU-2B, but with many additional features. In one of the Cross-Connected presets, the RSP-Z2 can create a local patch between two of its interfaces, with or without a backhaul link to an IP-based resource, such as a SIP phone, an MCC Console, or a Push-to-Talk over Cellular (PoC) application.

Beyond seamless integration with a Z-Series Controller, when the RSP-Z2 is in Custom mode, it provides configuration for up to four RTP or SIP recorder resources and one-way audio monitoring. Additionally, up to four resources – plus a USB headset – can all be in the same interoperability net. Moving resources in and out of net is accomplished by drag-and-drop, and context-sensitive help is always available for setup and configuration guidance.
