Abstract: PURPOSE:To prevent the congestion of common line signal networks by permitting a network management device to inhibit a correlated communication equipment to issue alarming at the fault generation. CONSTITUTION:According to the notified alarm, a network management device 7 inhibits the notification of alarm information through a common line signal network 6 and a switch monitor 1 inhibits the information notification of transmission lines 5a to 5c. When a transmission line fault 5 of a transmitter 2 reaches the device 1, a switch monitor 3 detects a fault to discriminate inhibiting information, but the information of the transmission lines 5a to 5c is not available so that the device 7 is not alerted. At the fault recovery, the device 7 makes an alarm editing processing and retrieves a facility correlation storage memory to set the information to an inhibit information format for the device 3, releasing the inhibit through the network 6. Based on the inhibiting information, the device 1 sets the alarm information notification of the transmission lines 5a to 5c to release the inhibit and the alarm information to the information format through the network 6 for the device 7, activating the alarm edition processing.
