A method for retrieving information related to a desired item from a database storing information which are collected from a system to be monitored is disclosed. A plurality of states of the system are displayed in time sequence on screen of a display. Each of the states is represented by a plurality of items of collected information. When inputting a desired item of a state selected from the states displayed on the screen, a state of the system is retrieved from the database based on the desired item, and the retrieved state is displayed on the screen.

Claims

1. A method for retrieving information related to a desired item from a database storing information about a submarine cable system composed of at least one submarine cable, submarine repeater, submarine branching unit, and joint box, comprising the steps of:

displaying a current state of the submarine cable system on screen of a display, wherein the current state is represented by collected information from the submarine cable system;

designating a component of the submarine cable system displayed on the screen, which encounters abnormal conditions in a different way to indicate occurrence of cable cutting;

retrieving information related to the designated component from the database;

displaying retrieved information on the screen;

wherein when a desired menu item including “

All”

is selected for the designated component, then at least one of detailed information of the designated component is displayed on the screen including a spare component to replace the designated component with, a schematic illustration showing a location of problem and other information depending on the desired menu item.
