  • Patent number: 9781021
    Abstract: A method applied to a wired network including a first network device and a second network device is disclosed. The first and second network devices each include a first set of connection ends and a second set of connection ends. Firstly, the first network device transmits a specific signal pattern through its first set and second set of connection ends. Then, the first network device detects whether a signal is received at its first set and second set of connection ends. If it is determined that a signal is not received at the first set connection ends while a signal is received at the second set connection ends, the first network device determines that its second set of connection ends is not correctly coupled to the second set of connection ends of the second network device.
