This Local and Metropolitan Area Network standard, ISO/IEC 8802-3: 1996 [ANSI/IEEE Std 802.3, 1996 Edition], specifies the media access control characteristics for the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) access method. It also specifies the media, Medium Attachment Unit (MAU) and physical layer repeater unit for 10 Mb/s baseband and broadband systems, and it provides a 1Mb/s baseband implementation. Specifications for MAU types 10BASE5, 10BASE2, FOIRL (fiber optic inter-repeater link), 10BROAD36, 1BASE5, 10BASE-T, and 10BASE-F are included. System considerations for multisegment 10Mb/s baseband networks are provided. Layer and sublayer interface specifications are aligned to the ISO/IEC Open Systems Interconnection Basic Reference Model and 8802 models. The 8802-3 internal model is defined and used.
