RSP-Z2: A Next-Generation Dual-Channel Interoperability Gateway

Communications environments today often involve a mix of analog radios, IP-based networks, dispatch systems, and Push-to-Talk over Cellular (PoC) platforms. Ensuring that these different communication systems can talk to each other smoothly is critical—especially for public safety, military, government, utilities, and industrial operations.

The RSP-Z2 is designed specifically for this challenge. It provides powerful, flexible audio patching between local radio networks and IP-based communication systems, allowing seamless interoperability across agencies, locations, and device types.

What the RSP-Z2 Does

The RSP-Z2 connects and bridges audio across:

• Traditional analog radios
• SIP and VoIP-based communications
• Push-to-Talk over Cellular applications
• RoIP (Radio over IP) networks
• Wide-area radio systems controlled via JPS Z-Series

This dual-channel gateway supports both local and remote communication resources and includes built-in tools for patching, monitoring, and system configuration.

Key Features

1. Versatile Connectivity

The RSP-Z2 supports:

• Radio interfaces and 4-wire circuits
• SIP devices and VoIP endpoints
• PoC applications and mobile broadband PTT systems
• RTP and RoIP audio streaming services

This flexibility makes it easy to integrate legacy radio networks with modern digital communication platforms.

2. Easy Network Integration

Whether used as a standalone unit or part of a wide-area system, the RSP-Z2 offers:

• Single Ethernet port operation
• NTP time synchronization
• Resource-specific tuning for optimal audio clarity

3. Simple Audio Patching

Users can choose from preset audio patching modes:

• Independent Passthrough
• Cross-Connect
• Cross-Connect with Backhaul

A customizable mode allows advanced setups including monitoring-only streams and multi-site interoperability.

4. Smart Trunking Performance

The unit features Adaptive Transmit Delay, a patented technology that ensures smooth audio handling specifically designed for trunked radio systems—reducing clipping and improving clarity.

5. Built for Wide-Area Control

When connected to a Z-Series Controller, all RSP-Z2 resources automatically appear for centralized management and unified system administration.

User-Friendly Interface

The RSP-Z2 includes a fully web-based GUI accessible from laptops, tablets, or smartphones. Users can:

• Configure resources
• Create or modify patches
• View live status indicators
• Monitor audio streams

Context-sensitive help guidance is built in, reducing training time and minimizing setup errors.

Additional Capabilities

• Supports wired and wireless USB headsets
• Compatible with standard JPS radio interface cables
• Optional encryption available for secure RoIP and talkpaths
• Supports up to four recorder channels for logging and compliance

Typical Applications

The RSP-Z2 is ideal for:

• Public safety and emergency response interoperability
• Federal and defense communication networks
• Municipal and statewide radio infrastructure
• Utility, transportation, and industrial communication control rooms
• Cross-agency joint operations and dispatch centers

Technical Highlights (Summary)

Final Thoughts

The RSP-Z2 brings reliability, interoperability, and scalability to modern communication environments. Whether used on its own or as part of a larger coordinated system, it provides organizations with a powerful tool to unify radio and IP-based communication resources—improving response coordination, situational awareness, and operational efficiency.
