Abstract:
A protection switching unit and a method of performing protection switching of the protection switching unit are provided. The method includes steps of detecting a fault that has occurred at a working path of a network; opening a first switch that is connected to the working path and closing a second switch that is connected to the protection path of the network; and maintaining a connection state of the first switch and the working path and a connection state of the second switch and the protection path, when a fault that has occurred at the working path is restored.
