Abstract
The network device includes a transceiver, a pattern generation unit and a pattern recognition unit. The transceiver connects to a communications medium. The pattern generation unit connects to the transceiver. The pattern generation unit is configured to generate a first code word in response to a self-test signal. The pattern recognition unit connects to the communications medium and a network entity. The pattern recognition unit is configured to receive the first code word from the transceiver and to determine whether the first code word includes a loop back pattern. The pattern recognition unit is configured to generate a second code based upon the first code word and to include in the second code word a pattern different from the first code word.
