IEEE 802.3az-2010

Clause 14 defines the functional, electrical, and mechanical characteristics of the type 10BASE-T MAU and one specific medium for use with that MAU. This clause also specifies the functional, electrical, and mechanical characteristics of the energy-efficient version of 10BASE-T, the type 10BASE-Te MAU, and one specific medium for use with that MAU. The relationship of this clause to the entire ISO/IEC 8802-3IEEE 802.3 LAN International Standard is shown in Figure 14¿¿¿1. The purpose of the MAU is to provide a simple, inexpensive, and flexible means of attaching devices to the medium. NOTE¿¿¿Support for both 10BASE-T and 10BASE-Te signal levels in a single device is not required. This MAU and medium specification is aimed primarily at office applications where twisted-pair cable is often installed. Installation and reconfiguration simplicity is allowed by the type of cable and connectors used. The 10BASE-T specification builds upon Clause 1 through Clause 7 and Clause 9 of this standard.
