Abstract

PURPOSE:To make it easy to release cross points of a line concentrator by detecting the power source of the line concentrator being put to work by an electric power feed detecting circuit, by counting a strobe signal generated by the detecting circuit and then by selecting a line concentration cross point. CONSTITUTION:The subscribers' interface device of a time-division exchange provided with a subscribers' device and line concentrator connected to subscribers, and an encoder and decoder is provided with subscribers' interface module 10. To this module 10, line concentrator 1 is connected, and power feed detecting circuit 13 of this line concentrator 1 detects the power source being put to work; and this circuit 13 informs counter circuit 11, strobe generating circuit 12 and data generating circuit 14 of module 10 of the power feed to generate an address signal, data signal and strobe signal by respective circuits 11-14, and with the address signal from common controller 6, an OR gate is opened to select a line concentration cross point, thereby making it easy to open the cross point.
