Abstract

PURPOSE:To transmit a control signal from a non-procedure terminal, by stopping tentatively the data transmission with a data exchange having a storage function, in transmitting data to the terminal not to be transmitted for data continuously during the data reception. CONSTITUTION:A data base 1 being a data transmission original transmits data 11, 12, 13, 14, 15 and 16 to a packet exchange 2 continuously. After the packet exchange 2 transmits the data 11, 12 received from the data base 1 to a telex exchange 3 as data 21, 22, the base 1 waits for the transmission of the data 13 during a timing 31, and after confirming that the communication control message from the telex exchange 3 does not come, the data 13 temporarily stored in the data exchange is transmitted to the telex exchange 3 as the data 23. After the data 24 is transmitted to the exchange 3, the transmission of the data 15 is waited during a timing 32. The packet exchange 2 receives a communication interrupting request 41 from the exchange 3 in the timing 32 and transmits a communication cut request 42 to the transmission original.

た。Therefore, if there is a data exchange or data terminal at the data destination that cannot transmit data in the reverse direction while data is being received, Kubasha will not be able to transmit data in the reverse direction from the data exchange to another data exchange until the data being transmitted is interrupted. Since data cannot be sent, a signal such as the end of communication that a data terminal attempts to send to another data exchange has to wait until the data from the data exchange is interrupted.

We have solved the above drawback by improving the data transmission method that was previously used, and the data exchanger with the storage function temporarily suspends data transmission. In some cases, the present invention provides a data exchange connection system that allows a data terminal to send a signal such as a request to terminate communication.

Data from the database 1 is temporarily stored in the PACT exchange 2, and this stored data is sent to the telex terminal 4 via the telex exchange 3, which does not have a storage function. Telex terminal 4 is a non-procedural terminal that cannot send data while receiving data. The PACT exchange 2 stops transmitting data when at least one of the data amount and data transmission time of continuous data transmission to the telex exchange 3 reaches a predetermined value, and then stops transmitting data until it resumes data transmission. During this time, the data scheduled to be transmitted is held in the PACT switch 2, and
Or, temporarily stop receiving data sent to PACT Switch 2.
