Abstract

PURPOSE:To perform data exchange control with a simple constitution and easy operation, by sectioning a plurality of subscriber circuits and office trunk into circuit groups according to each function, commonly connecting the circuit groups with the common control unit, and performing time sharing control with a given time slot. CONSTITUTION:A plurality of subscriber circuits 22a, 22b and the office trunk circuit 23 are sectioned at least into one circuit groups 21a, 21b, and 21c according to the functions possed by each, and those circuit groups 21a, 21b, 21c are connected to the common control unit 25 via the transmission and reception buses 26 and 27. Further, the terminal control circuit 24 is connected between the subscriber circuits 22a, 22b of the circuit groups 21a, 21b and 21c and the trunk circuit 23 and the buses 26 and 27 to perform time sharing control for the control unit 25 and the line groups 21a, 21b, 21c with a given time slot. The data transmission and reception with the control unit 25 is made with a given time slot of itself by the circuit groups 21a, 21b and 21c to perform the data exchange control between the subscriber lines 22a, 22b and the trunk line 23.
