Abstract

PURPOSE:To enable to automatically test the multiple address and conference lines and the trunks, by using the line level detection and control function given to the communication path control unit. CONSTITUTION:The lines Lo-Ln are allocated to the communication path control unit SW and in testing multiple address and conference trunk MTK, the level detection and control circuit LVC of the unit SW delivers sequentially the test instruction and test data to the trunk MTK via the reception line TRO of the trunk MTK via the reception line TRO. The transmission and reception control circuit MP of the trunk MTK sequentially delivers the test data with the test instruction from the line TRO via the interface circuit IF to the reception lines TR1- TRk corresponding to the test data received. The test data delivered is received at the circuit LVC and the state of the trunk MTK and the reception lines TR1- TRk is automatically tested.
