Abstract

PURPOSE:To enhance the economical performance for the circuit by the line concentration effect by carrying out the transmission of the control information without monopolizing the channel on the digital circuit as the control channel and thus securing storage for more subscribers. CONSTITUTION:Remote line concentrator 6 is installed at the point far away from time-division exchange 1 of the master station, and subscriber telephones 11-1-11-n are stored into concentrator 6. And the subscriber signal is put onto one of 24 channels on digital circuit 7 by the call and answer to be then connected to exchange 1 for the exchange process. Then master station remote line concentrator opposing part 4 of exchange 1 gives the line concentration to subscriber telephones 12-1-12-n via subscriber line concentration stage 5 for conversion into the 24-multiple PCM signal. And the control order is received via control line 9 and by the interface similar to the connection to time-division switch 2 of the master station through highway 8-n. This master station control part 3 and the interface are formed so that the subscriber state may be transmitted periodically via scanning line 10.
