physical layer signalling (PLS)

Physical Layer Signalling (PLS) is the part of the physical layer from the Ethernet layer model that is located in the data terminal equipment

. Physical Layer Signalling is used to exchange data between two MAC layers. This sublayer is used to control media access (CSMA/CD) and signals specific states of the physical medium, such as "medium busy", "medium free" or "collision on medium". The functionality is implemented in the Medium Attachment Unit (MAU).
