Abstract: A computer system for displaying the status of network nodes and links in a large telecommunications network is disclosed. An Overview windowing panel consisting solely of cell bullets representing the connection status of a large number of nodes and links in a telecommunications network is displayed on a computerized display device. The cell bullets are color coded to visually represent the connection status of the nodes and links. A panning rectangle which is moveable under mouse control throughout the Overview windowing panel telescopes the detail of a portion of the densely packed Overview panel onto a second windowing panel, the Detail windowing panel. The Detail windowing panel identifies the node connections displayed therein, and provides further information on the status of the node and connections therein.
