Description

General

The UIS-379 D Digital Intercom system, based on a modular and distributed architecture, ensures access by crew members of tactical vehicles to the on-board traffic voice / data and to the radio communications. Characterized by high reliability and intelligibility of communications, also offers numerous optional additional capabilities such as the wireless connection of the crew; recording services of voice and on-board video systems.

 
Performances
 

 

The UIS-379 D Digital Intercom system provides the following services:

  • Exchange in full-duplex between the crew members (all operators speak and listen to all the other operators).
  • Access to voice and data (from single workstations) to VHF and HF radio carriers.
  • Collection and distribution of information from the on-board computer (eg. Data on the vehicle status; alarms generated by on-board sensors; automatic forwarding of audio alarms).
  • High flexibility and rapid hw and sw updating.
  • Software’s ability to cancel different types of noise.
  • Ability to manage up to 30 users between Radio and Operators
  • B.I.T.E. embedded
  • DSP technology for improved sound quality
  • Based on digital TDMA BUS (2Mbps)
  • Up to 64 kbit /s capacity on asynchronous serial Fault Tolerant increased:
    • Absence of central unit
    • Automatic by pass of malfunctioning unit
