  • Patent number: 6158009
    Abstract: A communication monitoring and controlling apparatus for easily collecting monitoring information is connected to an existing network composed of a plurality of communication equipment. A management information collecting unit collects management information of each of the communication equipment. The management information is in an existing network management information format. A format converting unit converts the management information in the existing network management information format into management information in a new-type network management information format. The new-type network management information format is a format used by the new-type network, and handles the existing network composed of the communication equipments as one network element. The converted management information is transmitted to at least one operation system of the new-type network by a transmitting unit.
