Abstract

PURPOSE:To avoid disconnection of the circuit at the unregistered station for the selective calling system in which an individual talking is carried out by the single communication channel and with the same frequency shared by a number of radio stations, by using the on-hook signal in common to the answer individual signal and the call individual signal which are used originally in different purposes. CONSTITUTION:Both the calling station and answering station under the busy state are registered previously in the switchboard sides 1-3 based on the call and answer individual signals which are allotted individually to all radio stations 71-7N. Then this registration is cancelled by the on-hook signal common to all radio stations in order to secure the release of the circuit. In such radio circuit system, the call individual signal of the calling station or the answer individual signal of the answering station is transmitted along with the on-hook signal when the calling or answering station under the busy state and including the mobile station completes the talking. These signals are detected at the side of the switchboard. And only in case the detected signal is identical to the signal of the calling or answering station, the release is given to the circuit.
