In a network in which signals are transmitted bynswitching channels, a broad communication band isnassured. Even a signal, which has passed through answitch once, and can reach its destination if thatnswitch designates a channel, is output from that switchnusing an arbitrary channel in place of being outputnusing the designated channel. After that, the signalnwhich has made its journey around a ring once is outputnby designating a channel. Since the last switch means,nwhich a signal passes through, receives the signal fromnan arbitrary channel, a broad communication band can benassured. |
