Abstract

PURPOSE:To recognize a line fault in a short time by sending a signal monitoring the reception quality of a transmission line. CONSTITUTION:Signal transmissions 1a, 1b send transmission signal groups 2a, 2b to reception signal groups 4a, 4b respectively through transmission lines 5a, 5b. A carrier detect reception 3b representing whether the reception signal of the transmission line 5a is normal is given to the transmission signal group 2b, sent through the transmission line 5b, become the reception signal group 4a and the state is confirmed by the terminal equipment of the signal transmitter 1a. Conversely, a carrier detect signal 3a representing whether or not the recep tion signal of the transmission line 5b is normal is inputted to the reception signal group 2a and sent through the transmission line 5a, becomes the reception signal group 4b and the state is recognized at the terminal equipment of the signal transmitter 1b.
