Full Description

Scope

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

Purpose

To provide a cost effective solution for current IEEE 802.5 Token Ring users by specifically developing a standard for a High Speed Token Ring LAN based on the present IEEE 802.5 MAC, for incorporation into present 802.5 Token Ring environments with minimal increase in LAN complexity.

Abstract

Amendment Standard - Inactive-Withdrawn. This supplement specifies the changes required to ANSI/IEEE Std 802.5, 1998 Edition, (Base standard) and ANSI/IEEE 802.5r, 1998 Edition, and ANSI/IEEE Std 802.5j, 1998 Edition, (Amendment 1 standard) to support 100 Mbit/s Dedicated Token Ring (DTR) operation. The Base standard, together with the Amendment 1 standard, specifies shared and dedicated (point-to-point) Token Ring operation at both 4 Mbit/s and 16 Mbit/s using either the TKP Access Protocol or the TXI Access Protocol. This supplement extends Token Ring operation to 100 Mbit/s for the DTR CPort and Station using the TXI Access Protocol. Extensions to the medium access control (MAC) have been made to accommodate the requirements for high media rates (100 Mbit/s and above).
