摘要： PURPOSE:To make it possible to offer charge informing sevices even if a switching network can not discriminate a subscriber's number of a terminal, by allowing the switching network to send charge information to the terminal by a charge information request from the terminal prior to call cutting-off operation. CONSTITUTION:When a connection line between non-packet terminal 1 and a packet terminal is set, packet exchange unit 5 allots one charge information memory area in main memory unit 15 to a call connection. Once data transfer starts between terminals 1 and 6, exchange 5 collects charge information on the number of transmitted and received packets and stores it in the charge information area. After the data transfer, terminal 1 sends a charge information request. On receiving the request, packet multiplexer 4 edits cutting-off request packets including the charge information request and sends it to exchange unit 5. On receiving this request, exchange unit 5 takes charge information out and then sends it to unit 4. Unit 4 sends the charge information, character by character, to terminal 1.

摘要： PURPOSE:To realize a connection system which is tolerable in the range from a low track to a high track and reduces the need for reconstructing a packet switching network and devices for other communication networks, by turning a function of an inter-network connection over to a packet multiplication unit on a network connection system between the packet switching network and other communication network. CONSTITUTION:In the integrated data communication network which makes a mutual connection between a packet switching network and another communication network, subscriber's-circuit corresponding device 9 of packet multiplication unit 18 of the packet conversion network is connected to inter-network connection switch- board 3 in another communication network via intermittent transmission line 8. Further, common signal unit 7 of switchboard 3 is connected to device 9 of the packet switching network via common signal line 10. Then, a call control signal is transferred via common signal line 10 between central controller 4 of switchboard 3 and central controller 4' inside of packet switchboard 22 of the packet switching network by way of packet multiplication unit 18.
