In such a situation, the fault that occurred in the automatic exchange EX will be repaired,
When the fault notification information that was being transmitted from the automatic exchange EX to the terminal monitoring and control device SUP is stopped, the control device SC selects the digital terminal device DT that transmitted the fault notification information and updates the corresponding digital terminal in the signal transmission circuit SM. Fault information A corresponding to the downlink transmission path DL reaching the terminal device DT is set to a logical value of 0. The insertion circuit I provided in each downlink transmission path DL extracts the corresponding fault information A in the signal transmission circuit SM, and transmits it to the corresponding abnormality notification device AS via the downlink transmission path DL. In the abnormality notification device AS, the branch circuit D monitors the logical value of the fault information A transmitted via the downlink transmission path DL, and detects the fault information A.
The logical value of is transmitted to the terminal controller TC. When the fault information A transmitted from the abnormality notification device AS changes to a logical value of 0, the terminal control device TC sends an automatic switch

The desired digital terminal device DT is selected, and the congestion information C corresponding to the downlink transmission path DL leading to the corresponding digital terminal device DT in the signal transmission circuit SM is set to a logical value of 1. The insertion circuit I provided on each downlink transmission path DL extracts the corresponding congestion information C in the signal transmission circuit SM, and transmits it to the corresponding abnormality notification device AS via the downlink transmission path DL. In the abnormality notification device AS, the branch circuit D monitors the logical value of the congestion information C transmitted via the downlink transmission path DL, and
The logical value of is transmitted to the terminal controller TC. When the congestion information C transmitted from the abnormality notification device AS has a logical value of 1, the terminal control device TC determines that congestion has occurred in the automatic exchange EX, and controls the accommodation digital terminal device.
Congestion notification information is transmitted to the DT, and processing such as call regulation is carried out. In such a state, when the congestion state that had occurred in the automatic exchange EX disappears and the congestion notification information that was being transmitted from the automatic exchange EX to the terminal monitoring and control device SUP is stopped, the control device
The SC selects the digital terminal device DT that transmitted the congestion notification information, and sets the congestion information C corresponding to the downlink transmission path DL to the corresponding digital terminal device DT in the signal transmission circuit SM to a logical value of 0.
