Abstract

PURPOSE:To make a continuity test with small hardware without requiring a maintenance specialist by providing a means of inserting a channel continuity testing signal from a switchboard through the operator of the switchboard and a trunk which has the function of returning the signal to the switchboard recognizing the signal at the switchboard. CONSTITUTION:An incoming call from circuit 5 of the telephone switching system is detected by trunk 2-2 to inform a controller (not shown in the figure) of it. On the basis of the signal detected by trunk 2-2, the controller select idle switchboard 1 to close the path of switch 3 and sets the channel between switchboard 1 and circuit 5 while information switchboard 1 of the incoming from the controller. When the channel is set by trunk 202, the signal from switchboard 1 is recognized by the operator by returning the channel of trunk 2-2 to switchboard 1 again via contacts 7, 8, 10, and 15 of relay 6 to operate the switchboard 1. Then, relay 6 is driven from the controller to return the channel to circuit 5, so that a test of channel continuity is made easily.
