Abstract

PURPOSE:To attain the exchange of lines having optional transmission speed up to the transmission speed of a relay line and to remarkably improve the efficiency of using the relay line by providing a time division switch, a packet control part and a high speed packet line control part to constitute the titled system. CONSTITUTION:A subscriber line control part 30 transmits digital information on subscriber line 21-23 to the time division switch 302. The packet control part 303 discomposes the digital data on the subscriber lines into packet data, and transmits it to the high speed packet line control part 304. Simultaneously the part 303 composes digital data from the packet data transmitted from the control part 304 and transmits it to the time division switch 302. The control part 304 quickly transmits the packet data to a line multiplexing device 5, and simultaneously uses the relay line 4 as one data link in packet exchange without dividing the relay line 4 into plural channels. The relay line 4 is used as a large capacitance as it is. If plural communication lines are set up, data on each communication line is identified according to a packet multiplex system.
