ISO/IEC 14908-3:2011 specifies the control network Power Line (PL) channel and serves as a companion document to ISO/IEC 14908-1. It presents the information necessary for the development of a PL physical network and nodes to communicate and share information over that network.
ISO/IEC 14908-3:2011 covers the complete physical layer (OSI layer 1) including the interface to the Medium Access Control (MAC) sublayer and the interface to the medium. It includes parameters specific to the PL channel type, even though the parameters may be controlled at an OSI layer other than layer 1. ISO/IEC 14908-3:2011 also provides a set of guideline physical and electrical specifications for the power line environment as an aid in developing products for that environment.
