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 /spl Omaga/ balanced cable (twisted-pair) Categories 3 through 5, 150 /spl Omaga/ 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. 517 $a802.12-1998 - IEEE Standard for Information Technology- Telecommunications and Information Exchange Between Systems- Local and Metropolitan Area Networks- Specific Requirements Part 12 517 $aANSI/IEEE Std 802.12, 1998 Edition (Incorporating ANSI/IEEE Stds 802.122-1995 and ANSI/IEEE Std 802.12d-1997): IEEE Standard for Information Technology- Telecommunications and Information Exchange Between Systems- Local and Metropolitan Area Networks- Sp 517 $aANSI/IEEE Std 802.12, 1998 Edition 517 $aIEEE Standard for Information Technology- Telecommunications and Information Exchange Between Systems- Local and Metropolitan Area Networks- Specific Requirements Part 12 531 $aANSI/IEEE STD 802.12, 1998 EDITION (INCORPORATING ANSI/IEEE STDS 802.122-1995 & ANSI/IEEE STD 802.12D-1997) 606 $aComputer network protocols 615 0$aComputer network protocols. 676 $a004.62 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996279749003316 996 $aANSI$92072434 997 $aUNISA
