PURPOSE:To transmit a test data suitable for a terminal device at an arbitrary time by a request from the terminal device, by storing the test data transmitted from the terminal device in a data storage device. CONSTITUTION:The test data is stored in the data storage device 4 with a call from a terminal via a start analysis processor 5. When a call request packet CR is transmited from the terminal device 6, a packet call processing section 3 transmits a transmission request signal P1 to the start analysis processor 5. The analysis processor 5 transmits a start signal P3 to the data storage device 4 by it. The data storage device 4 accesses a file instructed with the start signal P3 and transmits the said transmitted test data P4 to the packet call processing section according to a procedure shown in a test data transmission control data. A series of data packet DT together with the transmitted test data is transmitted to the terminal device 6 from the packet call processing section 3. When the terminal device 6 completes the reception of the series of data packet DT, the terminal device 6 transmits a release request packet CQ and a disconnection confirming packet CF is returned from the packet call processing section 3. |
