IEEE/ISO/IEC 8802-3-2014 ISO/IEC/IEEE International Standard for Ethernet

IEEE/ISO/IEC 8802-3-2014 ISO / IEC / IEEE Международный стандарт для Ethernet

This standard defines Ethernet local area, access and metropolitan area networks. Ethernet is specified at selected speeds of operation; and uses a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplexoperation. Speed specific Media Independent Interfaces (MIIs) provide an architectural and optionalimplementation interface to selected Physical Layer entities (PHY). The Physical Layer encodes frames for transmission and decodes received frames with the modulation specified for the speed of operation, transmission medium and supported link length. Other specified capabilities include: control and management protocols, and the provision of power over selected twisted pair PHY types
