Abstract
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 N1 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 WS1 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.
Claims3
A monitor and control system comprising a network constituted by a plurality of monitored apparatus, and one or more of monitor and control terminals for monitoring and controlling the respective monitored apparatuses, wherein each of said monitor and control terminals comprises:
- means for reading information about states of one or more of failures occurring in said monitored apparatuses, via communication means;
- means for comparing severities in a plurality of failures read from the respective monitored apparatuses with one another and determining order of priority for the window display;
- and
- means for displaying windows so that a window of higher priority overlaps on a window of lower priority in accordance with the determined order of priority in the window display.
Dependencies are inferred from the claim text.
