Abstract
PURPOSE:To make the switch for test small to economize the constitution, by using the subscriber's line test slave device for the subscriber's line fault report accepting test commonly. CONSTITUTION:The fault concerning the subscriber is reported through SUB, LC, connection line 11 of LSW, CODEC, connection line 12 of TDSW, CODEC, subscriber's line fault accepting test trunk CPT, LTE-M, and LTD. In this case, if the test of subscriber's lines is performed continuously, the connection line is changed by the operation on test board LTD to perform this test through SUB, LC, connection lines 21 and 22, LTE-S, LC, connection line 23, CODEC, connection line 24, CODEC, CPT, LTE-M, and LTD similarly to the normal subscriber's line test.
