Abstract

PURPOSE:To integrate network configuration information databases of both a monitor system and a control system into one database by integrating the monitor system and the control system. CONSTITUTION:An alarm information transfer network interface section 4 of a monitor controller 3 informs alarm information from a transmission system configuration device 6 to a network management processing unit 1. The network management processing unit 1 references the network configuration information of a network configuration information database 2 to discriminate a fault block or to monitor and manage effect and extent of the fault thereby reflecting the monitor information onto the network configuration information of the network configuration information database 2. On the other hand, then when a control command from a communication network is inputted to the network management processing unit 1, the network management processing unit 1 sends the control information to the monitor controller 3 revising the network configuration information of the network configuration information database 2 and the monitor controller 3 gives the control signal to the transmission system configuration device 6 by a control information interface section 5 to control the communication network.
