Abstract: Communication devices coupled via a communication link may comprise physical layer devices that may be operable to determine presence of a received signal and to mitigate noise in the signal prior to processing and/or validating the signal. Analog and/or digital signal processing may be utilized to process the signal and/or mitigate noise in the signal. Noise mitigation may comprise near-end crosstalk cancelling and/or echo cancelling and/or may utilize local transmit signal information. Subsequent to noise mitigation, samples of the noise reduced signal may be accumulated and/or an average signal strength and/or average signal power level may be determined. The average signal strength and/or average signal power level may be compared to one or more thresholds which may be configurable and/or programmable.

Abstract: Systems and methods for implementing controller area network (CAN) communications between CAN nodes using Ethernet are provided. An Ethernet switch includes ports, each of which is configured to receive an Ethernet data packet (EDP) from a CAN node. Each EDP includes a CAN message, which includes an identification (ID) of a corresponding CAN node. A first port is configured to receive a first EDP and a second port is configured to receive a second EDP. The Ethernet switch also includes a controller module configured to detect a CAN conflict between the first EDP and the second EDP. The controller module is configured to select, in response to the detection of the CAN conflict, the first EDP or the second EDP based on the ID corresponding to the first EDP and the ID corresponding to the second EDP. The controller module is configured to route the selected EDP to a destination.
