Full Description

Scope

This standard defines Ethernet local area, access and metropolitan area networks. Ethernet is specified at selected speeds of operation; and uses a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) provide an architectural and optional implementation interface to selected Physical Layer entities (PHY). The Physical Layer encodes frames for transmission and decodes received frames with the modulation specified for the speed of operation,transmission medium and supported link length. Other specified capabilities include: control and management protocols, and the provision of power over selected twisted pair PHY types.

Purpose

The purpose of the amendment is to define specifications and management parameters for the provision of power to connected Data Terminal Equipment (DTE) with single twisted-pair IEEE 802.3 interfaces.

Abstract

Amendment Standard - Active.Specifications and management parameters for the provision of power via a single twisted pair to connected Data Terminal Equipment (DTE) with IEEE 802.3 single balanced twisted-pair interfaces are added by this amendment to IEEE Std 802.3-2015.
