Abstract

PURPOSE:To make the switch for test small to economize the constitution, by using the subscriber's line test slave device as the subscriber's line automatic test trunk commonly. CONSTITUTION:In the normal subscriber's line test, subscriber SUB is connected from test board LTD through subscriber's line test master device LTE-M, subscriber's line test trunk LTT, CODEC, connection line 15 of time division switch TDSW, connection line 13 of line switch LSW, subscriber's circuit LC, subscriber's line test slave device LTE-S, connection line 12 of test switch TSTSW, the connection line 10 of the subscriber's circuit, and the result obtained by testing SUB by LTE-S is transmitted to LTE-M. Meanwhile, when SUB dials the designation number of subscriber's line automatic test trunk SUBLT, SUB is connected to SUBLT through connection lines 11 and 12, LTE-S, LC, connection line 13, CODEC, and connection line 14, and thus, the subscriber is tested automatically.
