Abstract

PURPOSE:To enable to directly judge the object and content of the confirmation and callout at the callout side to called party, by changing the pattern of tone signal in series with two waves different from time intervals at the callout side, in a radio type selective callout device. CONSTITUTION:The selection code is set with code switches Sa1, Sa2 of a callout device and the start switch Sb is on, then the reference pulse produced from a clock generator 4 via an FF5 is input to a preset counter 2 and a given callout pattern is fed from a ROM3. The initial value of the address of ROM3 is fed via an encoder 1 from the code switch Sa, and the callout signal is delivered with the pattern that the tone signal f1 is fed for time (t) after the time (t) with the period (t) of the reference pulse, the tone signal F2 is fed for 2t, and nonsignal period for time (t). Thus, the callout tone of a receiver of called party is controlled, allowing the called party to confirm and judge the object of callout by caller.
