The ACU-1000, can interconnect up to 24 devices. The ACU-1000 can simultaneously cross-connect different radio networks, connect radio networks to telephone systems (or SATCOM systems) or network RoIP/VoIP talkpaths. It is completely scalable and field configurable to meet the customer and application's needs. It provides three different methods of operation for system redundancy and is neither computer nor network dependant for its operation. For more information on this device, please download the datasheet.
VoIP stands for Voice over Internet Protocol, which is a means of digitizing voice signals and sending them over a digital network. The digital network can be a LAN (Local Area Network), WAN (Wide Area Network), or the Internet itself. The NXU-2A embodies this VoIP technology in a way that enables communications radios to be interconnected across the room or around the world. Just as the ACU-1000 the NXU-2A works seamlessly with the Unified Communication software WAVETM
The ARA-1 is a radio-to-SIP interface which allows a radio to operate on a SIP network. This brings to existing SIP networks all of the features inherent to a radio system and to radio systems all of the features available with SIP. With this new technology, for example, an LMR system can be used to extend the SIP network into areas of rugged terrain, across bodies of water or into tunnels. Also, the ARA-1 can be used to create interoperability among radio systems as easily as creating a typical PBX conference call.
The Signal-to-noise voter SNV-12 will select, from up to 12 individual sites (or 36 in an expanded system), the input with the best signal quality. For FM receivers, the SNV-12 votes based on the noise level present in the received signals. Alternatively, a full Signal-to-Noise Ratio (SNR) calculation works best with AM or HF systems. Individual plug-in Site Voter Modules (SVMs) use digital signal processing (DSP) to measure noise and speech signal levels and to calculate the SNR. For more information please check the datasheet.
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.
