Abstract

PURPOSE:To enhance the operability of an extension telephone set by connecting incoming call response of a call operation when there is an incoming call, and connecting a calling sound when there is no incoming call, and giving priority to an incoming call response. CONSTITUTION:When a calling signal from a trunk line arrives to a trunk line trunk COT, a central processing unit CC identifies that there is an incoming call in the trunk COT, activates a buzzer BZ, and sets information in an incoming display memory ICM. When an extension telephone set A is off-hooked without depressing a button BO, information is transmitted from a line circuit LC to the unit CC, which decides an incoming call response by means of information of the memory ICM and connects the circuit LC to the trunk COT. When the telephone set A is off-hooked by depressing the button BO, the operation is decided to be an outgoing sound connection, and the circuit LC and an outgoing register trunk ORT are connected each other. Moreover, when there is no incoming call at the time of calling the telephone set A, the outgoing sound connection is attained. Thus the operability of the telephone set A is improved.
