Abstract
Digital call control system for a digital multiplexer. A series of telephone devices has circuits (= 1, ..., = 120) of line that are connected to a transmission system that basically comprises a multiplex and a processor or central process unit. A device that controls calls, detecting them and translating them to modulation of coded impulses is also placed. Act follows them transmit by a digital line. On the other side of this, the information becomes relay operating data acting as the character of the call has been. The device is also inspected to perform an occupied test to know if the line is occupied. The signals are decoded, completing the transmission with the central in a terminal unit (co).
