Abstract:
1. A method applied in a wired network, the wired network comprising a first network device and a second network device, the first and second network devices each comprising a first set of connection ends and a second set of connection ends, the first set of connection ends of the first network device coupled to the first set of connection ends of the second network device, the method comprising: transmitting, by the first network device, a specific pattern signal through the first set and second set of connection ends of the first network device to the second network device; responsive to not receiving, by the first network device, a return signal from the second network device at both the first and second connection ends, determining, by the first network device, a connection status of both the first and second set of connection ends of the first network device based on detecting whether reflected signals are received at the first set and second set of connection ends of the first network device, wherein if the first network device detects that a reflected signal is not received at the first set of connection ends of the first network device, and detects that a reflected signal is received at the second set of connection ends of the first network device, the first network device determines that the first set of connection ends of the first network device is correctly coupled to the first set of connection ends of the second network device and that second set of connection ends of the first network device is not correctly coupled to the second set of connection ends of the second network device; if the first network device determines that the second set of connection ends of the first network device is not correctly coupled to the second set of connection ends of the second network device, disabling a communication ability of the first network device under a first bit-rate mode by utilizing the first network device and enabling a communication ability of the first network device under a second bit-rate mode by utilizing the first network device.
