PURPOSE:To prevent synchronism deciding inspection between a central office and a terminal office from being delayed by providing the central office side with libraries for the central office and the terminal office and comparing the updating information of the central office with that of the terminal office which are stored in these libraries to decide their coincidence. CONSTITUTION:The updating information of libraries of plural terminal offices 3 connected to the central office 1 which is included in the central office 1 is read out from the 1st memory 11 and the library of the central office 1 which is included in the central office 1 is read out from the 2nd memory 13. The read updating information of the library of the central office 1 is updated with that of the libraries of the plural terminal offices 3 to decide coincidence between both the updating information. Even when the number of terminal offices connected to the central office is increased, the check of synchronism between the central office and the terminal offices can be rapidly processed and the inspection can be prevented from being delayed.
