The layer management, physical layers, and media that support this access method are also specified. Layer and sublayer interface specifications are aligned to the ISO Open Systems Interconnection Basic Reference Model and ISO/IEC 8802 models. Specifications for 100 Mb/s operation over 100 W balanced cable (twisted-pair) Categories 3 through 5, 150 Ω shielded balanced cable, and fibre-optic media are included. Optional implementation of redundant links to facilitate automatic recovery of network connectivity in case of link or repeater failure anywhere in the network path is specified. Rules for connecting redundant links within a network are defined.8802-12-1998 - Information technology-Telecommunications and information exchange between systems--Local and metropolitan area networks - Specific requirements--Part 12ISO/IEC 8802-12: 1998 ANSI/IEEE Std 802.12, 1998 Edition (Incorporating ANSI/IEEE Std 802.12-1995 and ANSI/IEEE Std 802.12d-1997): Information technology-Telecommunications and information exchange between systems--Local and metropolitan area networks - ISO/IEC 8802-12Information technology-Telecommunications and information exchange between systems--Local and metropolitan area networks - Specific requirements--Part 12Local area networks (Computer networks)Local area networks (Computer networks)004.68NjHacINjHaclDOCUMENT996280990903316ISO1086301UNISA
