Abstract

PURPOSE:To enable monitor stations to control one station to be monitored by making a connection to the next monitor station if there is no recall signal after a call signal from one monitor station is received and the transmission of data is completed. CONSTITUTION:Circuit switching-selecting circuit 23 performs switching operation to connect reception part 21 and transmission part 22 to transmission line 10 of the 1st monitor station. Then, a call signal is sent from the 1st monitor station and in response to it, data are transmitted. If no call signal is sent from the 1st monitor station after the completion of the data transmission, the output of timer circuit 27 permits circuit switching-selecting circuit 23 to supply a circuit connection signal to the next 2nd monitor station. Consequently, one station to be monitored can be controlled from monitor stations.
