Integrated Voice Communications System (IVCS)


IVCS is a computer-controlled telephone system that consolidates the communication functions and features normally provided by several systems into a single integrated network. The IVCS can be connected to the ship’s announcing system, shore telephone lines, radio communications and certain battle sound-powered telephone circuits. The system consists of two interconnected interior-communications switching centers, dial terminals, net terminals, terminal accessories, and associated cabling. The switching centers are located one forward and one aft. Nets are similar to sound-powered telephone circuits in that they are closed-loop circuits.
