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
