NIGHT CONCENTRATED CONTROLLING SYSTEM

摘要

PURPOSE:To attain a concentrated control for the maintenance of plural subordinate devices to be concentrically tested, by applying a maintenance command from a typewriter device connected to a concentrated test controller. CONSTITUTION:A concentrated test control is performed at night, etc. through a cordless channel access manual board system using a stored program control system with which a test is given to a subscriber circuit of a subscriber telephone terminal. A data circuit is provided between plural devices 25 which are concentrically tested at night and a concentrated controller which performs a concentrated test control at night. Then a maintenance command is fed through a typewriter device 42 provided to the concentrated test controller. Thus the maintenance command information is superposed on a MODEM circuit which gives the transmission/reception control to the test connection information. A means is provided to select and analyze the subordinate controllers to be concentrically tested, and plural controllers to be concentrically tested are maintained concentrically based on an indication given from a concentrated test controller.
