Abstract

PURPOSE:To simplify the control of a line concentration stage, by giving a logical 2-tier control and thus secure a separation of function among the processors as well as the independence of function. CONSTITUTION:The line concentractor LC that performs a concentration of subscriber lines consists of the line concentration control processor LC-LNP that performs controls within the LC plus the line concentration channel device LC-SP that stores a plural number of subscribers SUB. The calling of the SUB connected to the LC is sent to the trunk control processor TKP within the distribution stage device DIS-SW via the control information line LINE. The processor TKP transfers the information to the processor CP from the information bus BUS without giving any logical decision if the information is addressed to the central control processor CP. The logical decision of the calling detection signal is controlled by the processor CP, and a connection is given between the originating register trunk within the trunk device group TRK and the call line SP between the LC and the SP for reception of the dial figures of the SUB. Thus an isolation is secured for the controls among the processors.
