Abstract

PURPOSE:To simplify execution of the connection test for the local tandem by installing the monitor test unit via both the test outgoing and incoming trunks each and then providing the automatic connection test trunk to the exchange of the remote side. CONSTITUTION:Test subject trunk OGT is connected to outgoing sender trunk OST1 via route (3) of trunk like network TLN, and the dial figures are sent to the remote station via the information of central controller CC. By the dial figures sent in, the remote station is connected to the automatic test trunk to send back the ring-back tone. The ring-back tone reaches monitor test unit STF via outgoing trunk OGT1, route (4), test incoming trunk TSTICT key, test outgoing trunk TSTOGT, route (2) and terminal OTL each. And unit STF transmits the dial tone to the remote station to complete the test for trunk OGT1.
