A voting receiver transmits the communication back to a main repeater. Each voting receiver, which may be one of many, acts as a satellite, operates in receive only and forwards the system by IP. As each signal reaches the main repeater the system will analyse the incoming date and transmit onwards the highest quality signal. To personnel in the field, this allows them to operate as if they were connected to a much more powerful system.

The SNV-12 uses Digital Signal Processors to continuously monitor multiple remote receiver sites and select the receiver with the best signal quality. A typical application is an LMR system in which mobiles and portables can hear a repeater, but due to their lower transmit power, the repeater can’t hear them.

Remote receivers can be positioned in the communications dead spots, with audio from each receiver linked to the SNV-12 voter. It will select the best quality signal from all unsquelched remote receivers and forward this signal to the repeater for rebroadcast and/or monitor by a dispatcher, thus providing greater talk back range for the field radios. The PTG-10 pilot tone generator is available for use with receivers that lack pilot tone capability.

Modular interoperability system employing proven JPS DSP Technology and Radio over IP (RoIP) technologies Offers unsurpassed local and wide area interoperability by directly connecting or networking UHF, VHF, 700/800, HF, P25, military radios, iDEN and PTT devices, Cellular and Land line telephone endpoints With a growing focus on protecting our citizens and infrastructure, a coordinated command and control response has become a top priority for governments around the world. From homeland security to local public safety, from mission critical military applications to the latest commercial requirement, the ACU-1000 offers a robust and proven interoperability solution for incident command management.

Includes VoIP/RoIP technology to provide a means for regional, state, multi-state, and nation-wide interoperability over TCP/IP network links Provides three different methods of operation for system redundancy and is neither computer nor network dependent for its operation

The ACU-2000 IP interoperability gateway adds to the ACU-1000 feature set the ability to digitally converge existing radio systems with VoIP telephones, softphones, and VoIP telephone systems. All of the advantages of the open-standards SIP telephony protocol are brought to your to radio systems and radio connectivity added to your VoIP network. The ACU-2000 IP is modular, completely scalable and field configurable. The system joins disparate voice communications systems, allowing them to be flexibly connected together, monitored, and controlled over an IP network via an intuitive graphical user interface (ACU Controller software, included). The ACU-2000 IP continues all of the features of the ACU-1000 and adds interoperability with your SIP devices and systems.

The ACU-5000 interoperability gateway capitalizes on features developed by JPS Interoperability Solutions over the past decade. These features include a suite of sophisticated Digital Signal Processing (DSP) algorithms to resolve typical radio interoperability problems, interface cables for hundreds of radio makes and models, and quick setup templates for rapid deployment. In addition, the ACU-5000 is equipped with an intuitive Web-based Graphical User Interface (GUI), a built in Ethernet switch, and the ability to configure its voice communications channels per user preference type including: radio, telephone, VoIP (SIP), or JPS’s proprietary Radio over Internet Protocol (RoIP). This feature allows the ACU-5000 to be quickly reconfigured as needs change, with no need to purchase, carry, or swap-out hardware modules. Two versions are available – a light and compact tabletop version or a 1U high 19 inch rack mount unit in an aluminum enclosure.

The ACU-M is a feature-rich, simple-to-use device that can be networked and managed remotely. Weighing less than 3 pounds, the device is easily deployed and affordably priced, making it ideal for mission-critical interoperability NOW. The ACU-M provides interoperability between its four audio ports, a local handset port, and two optional Radio over Internet Protocol (RoIP) channels. With its comprehensive suite of digital signal processing (DSP) functions, it offers high functionality at a price that fits any budget.

Using the ACU-T Tactical Intelligent Interconnect System, a radio gateway can be rapidly configured and deployed to meet almost any interoperability application involving radios and telephones. The ACU-T offers the form-factor, flexibility and features required for tactical, fixed, or vehicular interconnect applications. Employing uses many of the same plug in modules and control software as the popular ACU-1000, this lightweight, tactical system is suitable for LMR, P25, TETRA, HF radio, telephones, trunking and SATCOM systems. It can also join WAIS systems (Wide Area Interoperability System)

The ACU SIP-LMR Channel Bank provides a seamless interface between radios and an IP- based network using the SIP protocol. This brings to existing SIP networks all of the features inherent in a radio system, including the ability to wirelessly reach otherwise inaccessible areas. For example, the ACU SIP-LMR can be used with an LMR system to extend the SIP Network into areas of rugged terrain, across bodies of water, or into tunnels. Radio networks can now benefit from all of the features available with SIP. These include interoperable communications among disparate radio systems that is as easy as creating a typical PBX conference call and also other PBX features such as Call Logging, Call Forwarding, and Call Recording.

JPS’s Wide Area Interoperability System allows its operators to monitor, communicate with, and link any number of communications devices and systems via an IP network. The intuitive WAIS Controller GUI enables the communications assets of multiple ACU Gateways and other devices to be joined in interoperability nets so that all types of radios, telephones, VoIP phones, satellite phones, etc., can communicate together locally, regionally, or in systems that span entire states. The system is designed to maintain operation even if infrastructure is lost due to natural disaster or other type of incident. The system’s distributed architecture ensures that, if any system hardware or segments of the inter-systems communications links are lost, all other portions remain operational. Local interoperability remains viable even if all outside communications links are down.
