Abstract

PURPOSE:To make it possible to use a clock adapted to every subscriber to be used by separating a master distributing frame of the transmission side and that of the receiving side in space to eliminate the short distance crosstalk on the communication system where information is transmitted and received in the two-wire time division system. CONSTITUTION:Transmission-side master distributing frame 7 and receiving-side master distributing frame 8 which transmit and receive information by two-wires, which accomodate two-wire transmitting line 4 to transmit information to subscriber terminals 2 and 3 and two-wire reciving line 6 to receive information from subscriber terminals 2 and 3 and are separated in space, are provided, and terminals 2 and 3 are connected by two-wire inter-subscriber connection line 5. Then, transmission information to terminals 2 and 3 is subjected to time division multiplexing, and transmission signals are transmitted to transmission line 4 through master distributing frame 7, and assigned information is received in terminal 2. Then, the transmission information is inserted into an assigned channel and is transmitted to terminal 3 through line 5, and information is received in terminal 3, and the transmission information is sent to receiving-side master distributing frome 8 of exchange 1 through line 6, thus transmitting information inputted to switchboard 9 to terminal 2 through master distributing frame 7.
