Abstract

PURPOSE:To enable connection test in a station, by designating a specific incoming trunk and outgoing trunk, and operating a test designation relay provided for the trunk. CONSTITUTION:When an ICT(or OGT) in matching with a signal system with an outgoing trunk OGT(or incoming trunk ICT) to be tested is designated, the corresponding relay T is operative. Transmission terminals TAT, TBT of a communication line of the OGT are connected to the receiving terminals RAT and RBT of the ICT with the contact of the relay T, transmission terminals TAT, TBT of the communication line of the ICT are to the receiving terminals RAT, RBT of the OGT, a transmission signal terminal SST of the OGT is to a reception signal terminal SRT of the ICT, and the terminal SST of the ICT is to the reception signal terminal SRT of the OGT respectively. From the intermediate position of the OGT and ICT, the connection is made to a test device TSTE, and the communication line can be monitored with the path of terminals L0-L3- trunk L-monitor device MON.
