Abstract
Abstract A large-scale centralized supervisory system for a plurality of network elements comprises a plurality of system zones. Each system zone has a plurality of supervisors connected to the transmission network elements, for supervising respective statuses of the network elements, a central supervisor for managing the network elements based on supervisory data transmitted from the supervisors, and an extensive supervisor connected between the supervisors and the central supervisor, for collecting the supervisory data from the supervisors and transmitting the collected supervisory data to the central supervisor and also to the extensive supervisor of an adjacent one of the other system zones. The supervisors collect current data indicating current statuses of the network elements, event data indicating changes in the current statuses of the network elements, and historical data indicating statuses of the network elements before the central supervisor is set up, and transmit the collected data to the central supervisor. The central supervisor generates a current table of the statuses of the network elements based on the transmitted data, displays data of the current table on the display unit, and generates history data including fault histories of the network elements for managing fault data of the network elements.
