Abstract

PURPOSE:To test automatically at the predetermined time without leaving the maintenance man from the test stand, by controlling a drawing relay and a test use trunk selecting means to form the intra-office folding loop. CONSTITUTION:The system provides a drawing relay which switches an incoming or outgoing trunk ICT or OGT to opposing station and intra-office folding loop and a test use trunk selection circuit TTS connected to a test use outgoing trunk TSTOGT or test use incoming trunk TSTICT for the drawing line from the incoming trunk ICT or the outgoing trunk OGT switched with the relay. The intra-office folding loop is formed for trunk test, by controlling the drawing relay and the test use trunk selection circuit TTS.
