Abstract

PURPOSE:To enable economical telephone service to subscriber groups at remote place, by providing a multiplex circuit and a multiplex separation circuit in a remote station time division exchanger and enabling to accommodate a subscriber line concentrator. CONSTITUTION:A multiplication circuit 9 and a multiplex separation circuit 10 are provided between a coding/decoding circuit 4 and an interface circuit 6, a subscriber line concentrator is accommodated to the multiplex circuit 9 and the control information of a subscriber 21 accommodated to a subscriber line concentrator 22 is received/transmitted from/to a master station 8 at a control circuit 5, allowing to enable to receive the same service as the subscriber 1 accommodated in a remote station exchanger for the subscriber 21 accommodated in the subscriber line concentrator 22.
