ABSTRACT:
A physical packaging position processing system of an exchange having exchange proper software and a terminal unit connected to the exchange and having terminal software. The exchange proper software has a system fixed database which is common to the whole of the system and which stores, in a hierarchical structure, a name table of frame unit name, frame name and module name and a name table of module main body name and card name carried in the module. Upon the system construction, a maintenance man prepares a physical packaging position database by utilizing the information of the system fixed database. In the event that a unit packaged in the exchange becomes faulty, a diagnostic result output section obtains physical packaging position information of the faulty unit from the physical packaging database on the basis of a diagnostic result obtained from a diagnostic unit and the physical packaging position information is graphically displayed on a display unit through a graphic display processing section of the terminal software.
