Abstract
PURPOSE:To eliminate the need for the provision of a selection signal sending function to an incoming side equipment by bringing an outgoing line to the calling state in the presence of an incoming call, applying loopback connection, transferring a dial tone and applying a 2nd line connection to the outgoing side terminal equipment. CONSTITUTION:An outgoing side equipment 11 sends a call signal from an outgoing line 1 to apply calling. Thus, a dial tone sent from a public telephone network 8 is received by the outgoing trunk 1 to confirm the dialing, a relay switch 6 is closed to connect the selection signal sending circuit 5 to the line and to send a selection signal of an incoming trunk 3 of the incoming side equipment 12. The incoming side equipment 1 uses the incoming trunk 3 to receive the incoming signal and to recognize the incoming call, sends a call signal from the outgoing trunk 4 to make a call. After the dial tone from the public telephone network 8 is received by the outgoing trunk 4, a relay switch 9 is closed and a reply signal is sent from the incoming trunk 3.
