Abstract

PURPOSE:To easily confirm the working state of a terminal equipment by providing the titled device with a timer for generating a signal to the terminal equipment at a previously fixed time and a detecting means for detecting the unused state of a communication equipment, and when both signals are generated, outputting prescribed data to a control device. CONSTITUTION:When a signal is generated from a common telephone driving circuit 10 at the time of unusing a telephone set 3 and a signal is generated from the timer circuit 11 at a prescribed time, a signal is sent from an AND circuit 12 to a control circuit 5. The circuit 5 generates a switch command to a switch 6 by the sent signal and the switch 6 changes over the connection of a telephone line 4 from the telephone set 3 side (a) to the terminal equipment 1 side (b). After confirming the connection between a center 2 and the equipment 1, the circuit 5 outputs a start command to a data generating circuit 8, so that line check response data is generated from the circuit 8. The data is modulated by a communication circuit 9 through the circuit 5 and transmitted to the center 2 through the switch 6, a line monitoring circuit 7 and a line 4. The center 2 receives the data, so that the normal driving of the device can be confirmed.
