PURPOSE:To confirm the connecting route, by giving a specific station code to each exchange station, transferring a test selection signal using a test connection special code to the preceding exchange station, and confirming the connection through the transmission of the said station code to the succeeding exchange station. CONSTITUTION:When a connecting test is made from a test device TSTE of an outgoing station EO-A, a test information is fed to a connecting controller MKR via a connector TSTC. A specific station code is given to each exchange station, and when a test selection signal is transferred to a relay station from the outgoing station, the relay station transfers the said station code specific to the relay station to the succeeding outgoing station and transfers the test selection signal to the preceding incoming station. When this incoming station receives a signal, the station code specific to the incoming station is sent out to the outgoing station via the relay station for incoming connection to complete the connecting test. |
