Abstract

PURPOSE:To prevent undesired telephone call without confirming the content of talking with the hook-off of a handset and to avoid charging to a caller when no talking is applied by enabling a caller only recognizing the condition relating to an incoming time and an incoming period to make a phone call. CONSTITUTION:In the case of the private mode set by a mode changeover switch 8, an incoming detection circuit circuit 3 detects it through a hook switch 2, informs it to a control section 4, which stores the incoming time to the memory section 6 and a timer section 5 is controlled to count and store the incoming time. In the presence of the succeeding incoming call after the end of incoming call, the control section 4 compares the incoming time and the incoming time span with the preceding incoming time and incoming time span stored in the memory section 6 and when the incoming time and the incoming time span both satisfy the requirements, the incoming tone generating section 7 is controlled to generate an incoming tone and the control section 4 sends it to a trunk line. The control section 4 also controls a speech switch 9 to connect a hook switch 2 and a speech circuit 10 to attain the talking.

Therefore, according to the present invention, it is possible to realize a telephone that can prevent unnecessary calls without having to pick up the handset and check the content, and does not charge the caller if the call is not made. In other words, with the telephone set of the present invention, only the calling line that knows the conditions regarding the incoming call time and the incoming time can make a call. Furthermore, if a caller who does not know these conditions makes a call, the telephone circuit will not be connected to the central office line, so the caller will not be charged even though the call is not an unnecessary call.
