And means for connecting the core wires in a group unit by grouping and managing the core wires in tape units of the cable structure.

  In addition, a construction instruction regarding cable construction, including a construction number in the information about the cable, the information about the core wire, and the information about equipment related to the cable and the core wire, And a construction instruction creating means for creating a construction instruction including information on core numbers to be connected, connection form, and related facilities.

  ADVANTAGE OF THE INVENTION According to this invention, when drawing up the plan which connects the core wire of a cable, a core wire can be displayed as a list on a screen. Therefore, the user can perform a plan for selecting and connecting the core wire through an interactive operation.

  Further, by managing the cores by grouping them in units of cable structure tapes, it is possible to devise a plan for connecting the cores in groups.

  Furthermore, a construction instruction sheet or the like can be created from the input equipment attribute information.

  As a result, there is an advantage that the labor for managing communication facilities can be greatly reduced. In addition, it is possible to collectively manage from communication equipment design to construction instruction creation, and the communication equipment can be effectively managed.
