  • Use Of Switch Circuits For Exchanges And Methods Of Control Of Multiplex Exchanges (AREA)

Abstract

PURPOSE:To realize the exchange of a great amount of information with a low exchange speed by respectively executing wave-length division multiplex of plural information whose amount is small to one time slot and exchanging it. CONSTITUTION:A multiplexed device 1 execute wave-length division multiplex of the information of (n) pieces from telephone sets 13(1)-13(n) by using the same number of wave-length and inserts the obtained wave-length division multiplex information block to the time slot of an in-highway #1. By a switch network 2, the communication information of respective in-highways #1-#(m) are exchanged and connected with desired out-highways #1-#(m) at every information of the information block of one time slot. A separating device 3 executes the wave-length separation of the converted communication information at every time slot, obtains the original information and sends it to respective terminals.
