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 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.
