Abstract

PURPOSE:To enable to transfer a trouble information from a slave station having only a digital circuit by continuing connection between a trouble information transferring device of a slave station and that of a master station using a general speaking circuit. CONSTITUTION:When setting initially an electronic computer of a slave station, connection 1 between an A/D converter C/D and an interface device for digital circuit DTI is made automatically by a time division switch TDSW. After that, the number of a push button dial signal receiver of a master station is sent out from the slave station, and connection 2 is formed in a switchboard SW in which a receiver of the master station is included. By this, the switch TDSW of the slave station and the switchboard of the master station keep up connection. A signal of specified frequency sent from a trouble information transferring device ALSND of the slave station is A/D converted and converted to analog from the switch TDSW through the switch SW of the master station and supplied to a trouble information receiver ALREC.
