Raytheon's JPS Communications announces the new ACU-M. The ACU-M is a miniature interoperability device built on the proven ACU technology. The device has an intuitive control panel for operation, field diagnostics, and programming. Weighing less than 3 pounds, the ACU-M is easily deployed and affordably priced, making it ideal for mission-critical interoperability. The ACU-M provides interoperability between its four audio ports (for radios or other devices), two voice over internet protocol (VoIP) channels, and a headset port. The unit is equipped with a comprehensive suite of digital signal processing (DSP) functions that allow it to competently interconnect radios in any band including HF, VHF, UHF, P25, 800-MHz and Nextel iDEN phones. The DSP function is notably absent from competitive counterparts. An Ethernet port provides access to a network for the VoIP channels and is also used for remote control and feature and firmware upgrades.
