Abstract

PURPOSE:To prevent a facsimile, etc. from troubles at the connection of the device by installing means discriminating a transmitted process signal and displaying it visually. CONSTITUTION:A sending process signal at the time is selected by a process signal selecting circuit 13 in a selected signal sending circuit 5 and sent to a signal checking circuit 4 in the opposite side through a sending control circuit 11. A signal discriminating circuit 6 in the signal checking circuit 4 informs a signal displaying circuit 7 that the received signal is a sending process signal. A display control circuit 8 makes a sending signal display device 9 display the process signal. When the discrimination circuit 6 discriminates that the process signal is a signal other than the ones to be supposed on transmission control process, the signal is displayed on the other display device 10 and fixed. Thus, the maintenance man can check abnormal signals by watching the contents of the display devices 9, 10.
