Abstract

PURPOSE:To increase the economy by drawing in the dial content of inspector directly to the line test trunk LTT connected to the test stand LTF and making symmetrical LTT and dial relay unit. CONSTITUTION:The relay function of the dial content of inspector is included in the line trunk LTT which is connected to the test stand LTF with the connector. It is not necessary to correspond fixedly the dial content relay unit with LTF, a plurality of LTF can be used commonly and the register sender and oscillator exclusive use for LTF are not required. Since LTT and LTF are connected with the connector relay or gate corresponding to LTT provided in LTF, the dial content of a plurality of LTF's is not mixed and a plurality of LTT's can be controlled from LTF and LTT can commonly be used with a plurality of LTF's. Thus, the economy can be increased.
