Abstract

PURPOSE:To enable a channel continuity test including confirmation of the functional operation of a trunk without intervention of the exclusive maintenance personnel, by recognizing a channel conductivity test signal inserted from a test device testing trunk or from the trunk itself by an operator od switchboard and informing it to the system. CONSTITUTION:The incoming call from the line 5 is detected at the trunk 2-2 and informed to the controller. The controller selects the board 1 with the signal detected with the trunk 2-2, the bus of the switch 3 is closed and the channel between the line 5 and the board 1 is set. In this case as one example of incoming call display to the board 1, the operator lamp display or alarm tone of the board 1 can be made by inserting a signal from the trunk 2-2 or trunk test device 4. The operator recognizes the said display and operates the board 1, to take out the said call. The system can read in the operation of the operator from the board 1, the incoming call from the line 5 is informed to be given to the board 1, and it is also confirmed that the channel continuity test from the trunk test device 4 to the board 1 is normal.
