Abstract
A line switching device includes multiple input ports to which signals are input and that include first input ports and second input ports different from the first input ports; multiple output ports that include given output ports; a branch unit that branches first signals input from the first input ports; and a switch that selectively outputs, among second signals input from the second input ports and branched signals branched from the first signals by the branch unit, signals that are to be switched to an output port among the given ports.
