Abstract

PURPOSE:To realize the highly efficient test for various types of test units of the remote station from the master station by transmitting the MODEM interface signal at the remote station to the test control unit via the subscriber terminal control unit and then performing the test to the subscriber to be tested. CONSTITUTION:The subscriber test is started when tested subscriber is counted to test stage 29. And the tested information operated at stage 29 by the maintainer is converted into the signal to the MODEM interface through test control unit 35 and then digitized through A/D converter 37 to be transmitted through the master station and the PCM circuit of the remote station. And at the remote station, the MODEM interface signal is transmitted to test control unit 13 via subscriber terminal unit 11, and subscriber test trunk 14 is transmitted as if the test information were received directly from stage 29. Thus the test is carried out to tested subscriber 10. In such way, the control is given to various types of test units provided at the remote control, ensuring the highly efficient test performance.
