IEEE Standard for Information Technology--Telecommunications and information exchange between systems--Local and Metropolitan Area Networks--Part 5: Token Ring access method and physical layer specifications 100 Mbit/s Dedicated Token Ring Operation
IEEE信息技术标准系统间远程通信和信息交换局域网和城域网第5部分:令牌环访问方法和物理层规范100Mbit/s专用令牌环操作
Generate a standard for 100 Mbit/s 802.5 Token Ring LANs based on the present 802.5 Token Ring MAC. It will support 2-pair Category 5 (100 ohm) and STP (150 ohm) cabling as specified in IS-11801 (and EIA/TIA 568A). The standard will consist of specifications for both stations and ports. MAC frame format will be based on that defined for IEEE 802.5, modified only to meet the specifications for the Tc PHY. The frame format between MAC and LLC is being preserved
