Abstract

PURPOSE:To perform the test by a closed loop through a jumper line, by providing a test line between the first automatic exchange and the second exchange set to the high and dry state in case that a subscriber of the automatic exchange is moved from the first exchange to the second exchange. CONSTITUTION:A subscriber to be moved of the second exchange SW2 is set to the high and dry state, and fragments of a changeover switch ARR2 are removed, and next, the second exchange SW2 reads out incorporated subscriber data on a basis of the number to the subscriber to be moved and discriminates that incoming is possible in the subscriber, and the second exchange SW2 transmits the telephone number of the subscriber of be moved to the first exchange SW1 through a continuity test circuit TST and a test line TL to connect incoming and forms a closed loop of J1-ARR1-SW1-TL-TST-SW2-ARR2-J2 by connecting the continuity test circuit TST and the same subscriber to be moved, and next, a test signal is transmitted from one terminal of the test circuit TST and is received by the other terminal, thus confirming that the jumper J2 is stretched correctly.
