Abstract

PURPOSE:To always secure the call between the monitor station and the monitored station by receiving the output of the call signal detector and the selection signal sent from the monitored station through the calling station detector circuit of the monitor station to carry out the logic operation and then displaying the monitored station which desires the call with the monitor station. CONSTITUTION:Call signal oscillator 20 plus switch circuits 19 and 21 which select and deliver either the call signal or the sending data to the transmission line are installed at the monitored station. While the monitor station selects plural number of the monitored station cyclically through station selector circuit 102. Then the data of the selected monitored stations are delivered, and at the same time the call signals are detected by call signal detector 113. Then calling station detector circuit 115 receives the signals of detector 113 as well as the selection signals for the monitored station given from call signal switch control circuit 114, and then carrying out the logic operation for the input of these signals to display 116 the monitored station desiring the call with the monitor station. As a result, the calling can always be secured between the monitor and monitored stations regardless of the polling time and the like.
