Abstract
PURPOSE:To completely and easily execute the check at installation without using any special inspection tool by providing a voice generating circuit section so as to attain exchange connection between a trunk line and a talking slave set, exchange connection between talking slave sets and exchange station between the talking slave set and the voice generating circuit section. CONSTITUTION:In case of depressing a test switch 102 at the installation of a telephone set 10, a control circuit 16 executes the following checks sequentially; fault check, opened talking lines 19A, 19B by ringing test of all slave telephone sets 12, voice signal fault check by transmission test of the voice signal to all the sets 12, transmission/reception function check of dial information by the transmission test of an answerback signal specific to each dial number dialed by the slave sets 12 and wiring mistake check of talking lines 19A, 19B by the transmission test of the answerback signal specific to the slave sets 12. When the checks by the control circuit 16 are conducted in order, the normality at each step is confirmed and efficient and sure checks without waste are applied. Thus, the check at installation is easily executed without using any special check tool.
