Abstract

PURPOSE:To perform the same test as the subscriver accomodated in the master station, by feeding the operation formation of the master station to the slave station through the use of communication channel of PCM circuit and returning the result of test via the same communication channel. CONSTITUTION:In testing the subscriber SUB of the remote slave station RE MOTE, when the maintenance personnel of the master station feeds the subscriber number and test item to the central control unit CC from the test stand LTD, the closing order of the test bus TB is delivered to the slave station control unit RLC from it via the communication channel for PCM lines. The control unit RLC indicates the test item to the subscriber test unit LTU, the point for the TB bus is closed, the test subscriber and test unit LTU are connected and required test is made, the result is digitized at the A/D converter to transmit it to the master station via the communiation channel of PCM line and it is displayed on the test stand LTD of the master station. When the master station allocated subscribers are tested, it is made the same method as the slave station.
