Centralized supervisory system for transmission network elements and method of supervising transmission network elements
First Claim
1. A system for centralized supervision of a plurality of interconnected transmission network elements, in a plurality of system zones, comprising:
- a plurality of supervisors in each system zone, adapted to be connected respectively to the transmission network elements, for supervising respective statuses of the transmission network elements;
central supervisors, one in each system zone, for managing the transmission network elements based on supervisory data transmitted from said supervisors, each of said central supervisors including means for selecting, initially and in the event of a fault of the system supervisor a system supervisor from among said central supervisors, to supervise all the transmission network elements in all of the system zones; and
extensive supervisors, each connected between said supervisors in one of the system zones and a corresponding central supervisor, for collecting the supervisory data from said supervisors and transmitting the collected supervisory data to the corresponding central supervisor and also to an adjacent extensive supervisor of an adjacent one of the system zones.

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.

4. A method of supervising a plurality of connected transmission network elements with a centralized supervisory system comprising a plurality of system zones each comprising a plurality of supervisors, adapted to be connected respectively to the transmission network elements, for supervising respective statuses of the transmission network elements, a central supervisor in each system area for managing the transmission network elements based on supervisory data transmitted from the supervisors, respectively, and an extensive supervisor connected between the supervisors and the central supervisor in each system area, said method comprising the steps of:
-
(a) collecting the supervisory data from the supervisors by the extensive supervisors; (b) transmitting the supervisory data collected in step (a) from the extensive supervisor to the central supervisor; and (c) transmitting the supervisory data to the extensive supervisor of an adjacent one of the other system zones.

5. A method of supervising a plurality of transmission network elements with a centralized supervisory system comprising a plurality of supervisors for supervising the transmission network elements, respectively, and a central supervisor for supervising the supervisors, the central supervisor having a display unit, said method comprising the steps of:
-
(a) collecting, with the supervisors, current data indicative of current statuses of the transmission network elements, event data indicative of changes in the current statuses of the transmission network elements, and historical data indicative of statuses of the transmission network elements before the central supervisor is set up; (b) transmitting the current data, event data, and historical data, collected in step (a), from the supervisors to the central supervisor; (c) generating, with the central supervisor, a current table indicative of the statuses of the transmission network elements based on the current data, event data, and history data transmitted in step (b); (d) displaying data of the current table on the display unit of the central supervisor; and (e) generating, with the central supervisor, history data including fault histories of the transmission network elements for managing fault data of the transmission network elements. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
