Abstract

PURPOSE:To realize both the generation and transmission of an optional interrupted pattern and then generate various types of ringing tones, by unifying various types of sound sources classified by the interrupted pattern into a single pattern and the same time installing a transmission pattern setting circuit. CONSTITUTION:The switch circuits SW1 and SW2 switch the signal sound source such as the CR signal sound source CRG or the like. In addition to these switch circuits, the CR signal pattern generating counter CRCTR, the IR signal pattern generating counter IRCTR, the SIR signal pattern generating counter SIRCTR and the VIR signal pattern generating counter VIRCTR are provided each. Thus various types of call signal patterns T1-T4 generated from the counters mentioned above are applied to the pattern selection circuit SEL, and the patterns T1-T4 are selected by the switch driving information and the call signal transmission request stored in the pattern selecting memory MEM supplied to the terminal P. Then the circuits SW1 and SW2 are controlled by the pattern selected through the circuit SEL, and the signals from the signal sound source CRG are applied to the ring trip detecting circuit DET in the form of various types of call signals.
