Abstract

PURPOSE:To increase the reliability and economy, by performing functional verfication automatically and quickly, through the control of the test unit connected with the verified exchanger with central control unit. CONSTITUTION:The test unit TSE is connected to the verified exchanger, the subscribing telephone set SUB and the opposing unit of the outgoing trunk and the incoming trunk T of the exchanger are simulated to TSE, and after the function verification procedure data prepared in advance from the input and output unit TTY is stored in the memory unit M with the condition of working of exchanger, the test unit TST is controlled with this procedure from the central control unit CC via the data channel unit DCH and separated common line unit CSE or the reception distributer SRD, relay controller RC and signal distributer SD, and various input signals accompanied with the connection operation of call is given to the exchanger. The corresponding output from the exchanger is detected with TSE and confirmation with CC is performed, allowing to verify te normality of program logic.
