PURPOSE:To apply an incoming control without worrying about the ineffectiveness of the incoming, by storing the number of the originating station during an incoming control and cancelling the incoming control state in case the incoming calls exceed a memory enable number. CONSTITUTION:With push of the incoming control switch 6, the incoming control lamp 7 glows to show the incoming control mode. At the same time, the control part 5 sends back the signal showing the incoming control mode in case an incoming arrives from another station. When the originator transmits the number of the telephone number of the originating station, the number is detected by the number detecting part 2. Then 1 is added to the incoming call number counting part 3, and the number of the originating station is stored in the memory 4. When deciding that a coincidence is secured between the number accumulated at the part 3 and the number of the memory enable incoming calls stored in the memory 4, the control part 5 gives an automatic cancel to the incoming control mode, and at the same time controls the lamp driving circuit 8 to give a blinking to the lamp 7 or change the light emitting color. Thus a cancel of the incoming control is displayed for the subscriber. |
