Abstract

PURPOSE:To dispense with the retrieval of a null circuit from a terminal equipment and to effectively use a circuit by requesting and storing information on the sending subscriber's number when an incoming call arrives at a leased circuit for incoming call, and calling the incoming call based on the call originating subscriber's number information via a leased circuit for transmission after disconnecting the circuit once. CONSTITUTION:All (m) terminal equipment 106 call the leased circuit 104 dedicated for incoming call. When the incoming call arrives at a reception port 150, an incoming call detecting part 151 detects it, and the circuit between the terminal equipment 106 and an information processor 101 is connected. When the circuit is connected, a subscriber's number receiving part 153 requests the input of the call originating subscriber's number information to the terminal equipment 106. When the information is inputted, the subscriber's number receiving part 153 stores the subscriber's number information in a subscriber's number storage part 154. After that, a compulsory disconnection part 152 is started up, and the circuit between the information processor 101 and the terminal equipment 106 is disconnected. Therefore, the leased circuit 104 for incoming call is not in a busy state, which enables a call from another terminal equipment 106 to be performed.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention. The information processing apparatus 101 of this embodiment is connected to the public line network 103 via n + 1 information processing apparatus side subscriber lines 102.
Of these n + 1 subscriber lines 102 on the information processing apparatus side, one is used as an incoming line 104 and the other n lines are used as an outgoing line 105. In addition, m units (n
Each of the terminal devices 106 of << m) is a terminal side subscriber line 1
It is connected to the public line network 103 via 05.

The information processing apparatus 101 has an incoming call leased line 104.
150, the incoming call detection unit 151 and the forced disconnection unit 152 connected to the incoming port 150, the incoming call detection unit 1
51 and the subscriber number receiving unit 153 connected to the forced disconnection unit 152, the subscriber number storage unit 154 connected to the subscriber number receiving unit 153, the transmission unit 155 and the transmission unit connected to the subscriber number storage unit 154. Connected to 155 and n
N calling ports 156 respectively connected to the outgoing line 105 of the book, a required business number receiving unit 157 connected to the n outgoing ports 156, and n tasks connected to the required business number receiving unit 157. It has a processing unit 158.

Next, the operation of the information processing apparatus 101 will be described. All the m terminal devices 106 call (dial) the incoming call dedicated line 104. When an incoming call is received at the receiving port 150, the incoming call detection unit 151 detects it and the line is connected between the terminal device 106 and the information processing apparatus 101. Subscriber number receiver 1 when the line is connected
53 requests the terminal device 106 to input the sender subscriber number information. When the sender subscriber number information is input from the terminal device 106, the subscriber number receiving unit 153 stores the subscriber number information in the subscriber number storage unit 154. At the same time, the subscriber number receiving unit 153 causes the forced disconnection unit 1 to
