PURPOSE:To execute simply the data transmitting receiving test under optional setting conditions regardless of the environment by interrupting the line at the time of the test of a tested object device, executing the test by a spurious signal among the data accumulating device and the peripheral input output device and a data processing device, connecting a line control device to a line after the test is completed and transmitting and receiving the data. CONSTITUTION:When a line spurious test device 81 is operated, the connection is cut off between a line control device 82 and the line 4, and the connection is logically executed to the line false testing device 81 and the line control device 82. The line spurious testing device 81 outputs a test starting indication to a data displaying device 6, etc. After that, a data transmitting test is started between a tester and an object device. The data inputted by the tester or inputted by a data accumulating device 5 are sent through the line spurious testing device 81 to the line control device 82. After the action of the line spurious testing device 81 is completed, the logical line is returned to the previous section between the line control device 82 and the line 4, and thereafter, the data between an opponent communication processing device 2 and the tested device through the actual line 4 are transmitted and received. |
