。When a data processing device that performs data communication with a terminal device via a modem and a communication line cannot operate normally, a failure notification code is sent to the terminal device connected to the modem and communication line in place of the data processing device. The center fault notification code transmitter that sends out the fault notification code is equipped with a signal line monitoring circuit that monitors the data set ready signal and transmittable signal from the modem when the fault notification code transmission to the line side is finished, and when the fault notification code transmission is finished. A center failure notification code transmitter, characterized in that the data set ready signal and the transmittable signal are in an OFF state to indicate abnormality detection.
