1. A physical layer device, comprising:
an input to receive a signal from a shared transmission medium of a wired local area network, the shared transmission medium of the wired local area network comprising a physical medium that is a communication path between nodes that are part of the wired local area network, the nodes including respective instances of physical layer devices; and
one or more processors to, at the physical layer device and in a physical layer of an Open Systems Interconnection (OSI) model:
identify coding violations in the signal received via the shared transmission medium of the wired local area network, the coding violations including two-level differential Manchester Encoding (DME) violations wherein signal transitions are not detected at respective clock transitions;
determine a rate of the coding violations in the signal; and
estimate a bit error rate of the signal to be the determined rate of the coding violations.
