The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) allow use of selected Physical Layer devices (PHY) for operation over coaxial, twisted pair or fiber optic cables, or electrical backplanes. System considerations for multisegment shared access networks describe the use of Repeaters that are defined for operational speeds up to 1000 Mb/s. Local Area Network (LAN) operation is supported at all speeds. Other specified capabilities include: various PHY types for access networks, PHYs suitable for metropolitan area network applications, and the provision of power over selected twisted pair PHY types. 517 $a8802-3-2021 - ISO/IEC/IEEE International Standard - Telecommunications and exchange between information technology systems--Requirements for local and metropolitan area networks--Part 3 606 $aData processing 615 0$aData processing. 676 $a658.05 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996574636103316 996 $a8802-3-2021 - ISO$92584072 997 $aUNISA
