Abstract
A communication device includes a time switch array unit which performs a switching of transmission lines. A switch unit performs a switching connection from a protection channel line among the transmission lines to a working channel line, for each channel formed in the transmission lines. A bridge unit performs a switching connection from a working channel line among the transmission lines to a protection channel line, for each channel formed in the transmission lines. A control unit performs a recovery of a signal transmission on the working channel lines by controlling the switching connections of the switch unit and the bridge unit.
