TEST CONTROL SYSTEM

摘要

PURPOSE:To realize a test control system without requiring modification of function of a central processing system device or the like and no adverse effect other subscribers by separating a part or all of call processing control of subscribers from the central processing system device and making a part or all of the call processing control of the said subscriber share with a controller having the call processing function of a test system. CONSTITUTION:Information of an outgoing test request inputted from a test board 16 is transmitted to a controller 11 via a controller 13. When an outgoing request command is received, the controller 11 issues a request of processing separating a subscriber 17 from a subscriber line concentrator 19 to a central processing system device 10. The central processing system device 10 sends a control signal separating the subscriber line concentrator 19 to a subscriber circuit 18 and transmits the notice of completion of separation to the controller 11 after the separation. When the said notice is received, the controller 11 operates a switch 14 to connect a subscriber 17 and a subscriber circuit 15 for test. The channel is separated completely from the subscriber line concentrator 19 and a network 20 and its call processing is managed under the controller 11 independently of the central processing system device.
