Abstract
PURPOSE:To perform secure interruption from one subordinate station by stopping the transmission of the radio equipment of another subordinate station by a timing pulse generated by the radio equipment of the latter subordinate station, in a radio transmission controlling system for the interruptible subordinate stations. CONSTITUTION:In the radio equipment of a master station, an interruption clock pulse generator 3 generates a constant timing pulse, which is ANDed with the busy signal H of a calling subscriber of the master station by an AND circuit 4 to be transmitted for a constant time of an interruption permit signal I. At a subordinate station on a duplex transmission system, transmission is stopped for the time when the interruption permit signal I is detected in a busy state. At a subordinate station on a two-wave press-to-talk system, a pulse generating circuit 104 is controlled by the rise of the detection of an interruption synchronizing signal J to obtain clock pulse signal K which synchronizes with constant timing. Further, pulses with constant time width which repeats at constant timing are generated by the pulse signal K, and consequently transmission is forced to stop repeatedly even when the press-to-talk type subordinate station is busy.
