IEEE 802.3ab-1999

Define physical layer characteristics and specifications for 1000 Mb/s operation on 4 pair of 100 ohm Category 5 balanced copper cabling as defined by EIA/TIA-568-A, Annex E or its equivalent as built from material specified by ISO/IEC 11801:1995. The purpose of this project is to extend the 802.3 protocol to provide 1000 Mb/s operation over installed Category 5 generic facilities balanced copper cabling. Amendment Standard - Superseded. Superseded by IEEE Std 802.3-2002. This IEEE Standards product is part of the 802 Family on LAN/MAN. Abstract: Type 1000BASE-T PCS, type 1000BASE-T PMA sublayer, and type 1000BASE-T Medium Dependent Interface (MDI) are defined. This supplement provides fully functional, electrical and mechanical specifications for the type 1000BASE-T PCS, PMA, and MDI. This supplement also specifies the baseband medium used with 1000BASE-T.
