PURPOSE:To enable the rejection of incoming call through the operation by a subscriber, by making an incoming call rejection registration to a subscriber storage device. CONSTITUTION:It is assumed that a PB subscriber 1 desires to reject incoming calls from time t1 to t2. In this case, by dialing a specific number, the subscriber 1 is connected to a special trunk 3. Next, the subscriber 1 operates a PB button of a telephone set and dials the start of registration of incoming call rejection, starting time t1, and end time t2. On the other hand, the special trunk 3 transmits each information to a control section 4. The control section 4 receives the information and the accomodating position information of the subscriber 1 from an exchanger 2 and stores the incoming rejection information to a subscriber circuit storage device 5 storing the status of each subscriber circuit corresponding to the accomodating subscriber circuit of an exchanger 2. In this state, considering that another subscriber 6 makes a call to the subscriber 1, since the content of the subscriber circuit storage device 5 is checked in the process of exchange connection, the subscriber 1 is not called out. |
