Communication Control Unit

Communication Control Unit 9001363

The CCU is the core of the communication and information sign system. It controls the audio communications: Public Address (PA) from the operator to the passengers, Operator intercom (IC) between crew members and passenger intercom between operator’s position and passenger intercom units. Its multiple and independent integrated audio power amplifiers allow to selectively make announcements to interior and/or exterior, and/or different zones and/or to be used for redundancy purposes. Its powerful processor digitizes the audio (VOIP) for train wide communication through its 10/100 BASE-T Ethernet interface.
