PROBLEM TO BE SOLVED: To provide a highly reliable network management system that can prevent erroneous connection when field radio management stations are installed with a redundant configuration, and can increase failure resistance by allowing a backbone network to be redundant.SOLUTION: A network management system in which field radio management stations having built-in gateway and system management functions are redundantly connected is characterized in that these field radio management stations are connected with each other via cables for synchronization and connectors. |
