PURPOSE: A trunk testing device of full electronic exchanger is provided to enhance reliability and the management function to transmission quality on station lines CONSTITUTION: The trunk testing device of full electronic exchanger comprises: a man-machine communication processor interfacing to an operator with man-machine communication mode; a trunk testing device controller outputting a error bit rate test failure message toward said man-machine communication processor and stopping the test when the channels connected to the trunk to be tested are No.26¯31 and outputting the order related to the bit error rate test including an operation flag when not No.26¯31, in a mixed type of trunk in referring to the trunk related information stored in a trunk interface controller if a bit error rate test order is applied from the operator through said man-machine communication processor; a time switch switching the channel in said bit error rate test; a time switch controller controlling said time switch to realize said channel switching if the channel to be used in the trunk test and subhighway information to be connected to the channel are applied from said trunk test device controller; and a trunk testing means transmitting said subhighway information to be connected into said trunk test device controller to inquiring said channel switching if the order related to said bit error rate test is applied from said trunk test device controller.
