On a screen of a display unit, all NODEs in a ring network to which a connected node (NODE) belongs are minimized and displayed on a screen of a display unit, and a line connecting NODEs with each other is displayed between respective NODE icons. Display colors of the NODE icon and the line icon are changed depending on presence/absence of a failure. Further, a display color of each object displayed in each window varies in a plurality of stages in accordance with a degree of a failure.

Terminal apparatus for operator and communication path setting method

A graphics map of an area in which a system is set is displayed on a screen of a display unit, and minimized stations and line connecting between the stations are displayed on the map. Display colors of the station icon and the line icon are changed in accordance with presence/absence of a failure. When each station icon is clicked, a window showing a list of NODEs belonging to that station is opened, and a NODE having a failure and a NODE having no failure are also distinguished from each other by changing the display colors in this window.

Network management equipment and communication path setting method

The present invention provides to an access management method and the communications apparatus capable of limiting an access from a monitor and control apparatus to a communications apparatus. In each of transmission apparatuses N to Nm, identification information of a monitor and control apparatus requesting an access is first obtained, and a uniquely determined level for each of monitor and control apparatuses WS to WSm is determined. A function of the monitor and control apparatuses requesting an access and its operation type are identified and, after that, it is determined on the basis of a predetermined table whether the access can be permitted or not.
