Title:
INFORMATION PROCESSOR USING PUBLIC LINE
Document Type and Number:
Japanese Patent JP2626519
Kind Code:
B2
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.
