A reset circuit and a reset method are provided in order to operate a power switch of the main body of a communication device installed in an inaccessible place such as a remote place or a high-altitude place and to execute a reset by software in the case of having problems with firmware or software of a communication device installed in a remote place. In a reset circuit for a communication device, the device is reset by using link information, which indicates whether a physical layer is connected or disconnected to an external interface.
