General Information

Transportable Interoperability Switch

ACU-T is a Transportable Intelligent Connection Unit (Intelligent central) that can communicate all type of wired/wireless communication devices at different infrastructures.

Allows integrating VHF, UHF, HF/SSB radio devices, Satellite phones, GSM phones and telephone centrals to the system, which are at different frequencies and existent in the user inventory.

Connection between the communication devices can be made by users directly as well as operator.

Five different communication devices can be connected to the system due to user requirements.

The operator can perform Bi-lateral or multi-lateral conferencing over the ACU-T as well as invitation to all radio devices simultaneously in the emergency.

ACU-T unit offers perfect solution for the integration of the different communication devices to the system through it’ light, transportable and user-friendly composition.
