Abstract

PURPOSE:To secure the intra-office connection although all trunk circuits are faulty for the remote station by providing the auxiliary switch for intra-office connection at the remote station. CONSTITUTION:The circuit fault detection circuit is provided to each trunk circuit, and these detection circuits are monitored concentrically by circuit monitor circuit CONT. When the fact that the fault affects all circuits is identified, the monitor circuit informs this to remote station control unit RLCC and at the same time starts intra- office connection unit TDSW along with switching of change-over switches t11- tm1. As a result, the busy tone or talkie is sent back to all intra-office requests to given to outside of the remote station, but the intra-office connection is possible. While the fault diagnosis of the trunk circuit group is given to the master station via circuit CONT during the fault state by switching change-over switches SWt12- tm2. When the release is confirmed, the normal operation sequence is reovered under the control of circuit CONT.
