PROBLEM TO BE SOLVED: To provide a line test confirmation system that can conduct a test of only an extension line by insertion/extraction of a test pattern signal, attain the connection to a measurement device and confirm the normality of the extension line without having effect on an existing operating line contained in a substantial interface panel by changing the connection destination of the extension line extended between devices from the substantial interface panel to a test interface panel. SOLUTION: A device such as a transmitter provided with 1st and 2nd interface panels containing lines is provided with a line setting section that interconnects lines contained in the 1st interface panel and lines contained in the 2nd interface panel by means of software control, and the test interface panel as a destination of connection change of lines connected from the 1st interface panel to the 2nd interface panel is connected to the line setting section. |
