Developed for use in armored and utility vehicles, the SOTAS digital intercom system provides crystal clear communication between crew members inside a vehicle and externally over combat net radios and field cables. SOTAS is a highly modular star network consisting of a central switch and several crew stations. Dependent on the functionality of the crew, specific boxes are available providing different functionality (e.g., Commander’s Box, Crew Box, Remote Control Box). Using the latest digital transmission technology, voice is distributed digitally over the system providing excellent quality. Using Digital Signal Processors, any noise is filtered out, and the system will switch on automatically in case of any voice communication. The single coaxial highway cables carry power, digital voice, control, and signaling data between the elements of the system. The use of simple coaxial cables ensures easy installation and error-free operation.

Features and capabilities include:

  • Poised for future growth with an IP-based, open systems architecture
  • Coaxial two-wire interconnections
  • Compatibility with all in-service radios
  • Digital voice operated switch
  • Advanced BITE with standard PC diagnostic facility
  • No single point of failure
