`AbstraeL’ This Local and Metropolitan Area Network standard, ISO/IEC 8802-3 : 1993 [/~iNSI/IEEE Std
`802.3, 1993 Editionl, specifies tim media access control characteristics fi)r the Carrier Sense Mult;iple Access
`will~ Collision Detection (CSMA/CD) access method. It also specifies the media, Medium At~achm.ent Unit
`(MAU) and physical layer repeater unit for 10 Mb/s baseband and broadband systems, and it provides a
`! Mb/s baseband implementation. Specifications ibr MAU types 10BASES, 10BASE2, FOIRL (fiber optic
`tot-repeater link), IOBROAD36, 1BASE5, and 10BASE-T are included. System considerations for multiseg-
`meat 10 Mb/s baseband networks are provided. Layer and sublayer interface specifications are aligned to
`the ISO Open Systems Interconnection Basic Reference Model and 8802 models. The 8802~3 internal model
`is defined aud used.

`National bodies that m’e members of ISO or IEC participate in the development of Intm’na-

`dam wifl~ particular iields of technical activity. ISO and IEC technics! committees collaborate
`in fields of mutual interest. Oilier international organizations, governmental and nongovern-
`mental, in liaison wit,h ISO m~d IEC, also gake part il~ the work.
`In the field of information technology, ISO and IEC have established a joint technical co~n-
`milieu, ISOBEC JTC 1. Draft International Standards adopged by the joint ~chnieal commit-
`tee are circulated to national b~dies fbr voting, Publication as an International Standard
`requires approvM by at: lem~t 75% of the national bodie~ casting a vote.
`In 1935. IEEE Standard 802,3-1935 was adopted by ISO ~bchnical Commit,tee 97, In~%rma-
`tion p~vc.es~i,~g systems, as draft. International Standard ISO/DIS 8802~3. Following film proce-
`dures described above, t:he S~andard was sub~;equently approved by ISO and published a~ ISO
`8802-3 : 1989, incorporating ISO 8802-3/DAD I which had resulted from the adop$ion by ISO
`in I987 ofANStflNEE Std 802.2a.
`A fm-ther revision wa~ subsequently apwoved by ISO/INC JTC 1 in 1990, i~corporating
`[SO/IEC 8802-3/Amendments 2 and 5.
`A third edition, published in 1992, incorporated ISOiIEC 8802-3/An~endm.en.ts 3 and 4.

`LAYER
`
`This family of standards deals with the Physical and Data Link layers as defined by t;he. ISO Opm~ Sys-
`tems Intercmm¢ction Basic Reference Model (!SO 7498 : 1984). The. access standards define four types of
`medium access technologies and associated physical media, each appropriate t.br part:icular npplications ar
`system objectives. Other types are under investigation.
`The standards defining these technologies are as follows:
`
`(1)
`
`(2)
`(3)
`(4)

`The main body of this standard serves for both t, he ISO/IEC 8802-3 and ~S]/fEEE Std 802.3 stan-

`only. The Appendixes serve as useful ret[~rence material to both standards.

`which have expressed an interest, in parI;~cipating in tim development of~he standard,
`Use of an IENE Standard is wholly voluntary. The existence of an IEEN Standard does no~

`s~:andard. Every IEEE Standard is m~bjeetcd ta review el; leasl; nuce avory ~iv~ years f~r
`sion or reaffirmation. Vflmu a document is more than five years old, and has no~ been rest:
`firmed, it. is reasonable to conclude that its contents, although stil! oF some value, do
`wholly reflec~ the pre~en~ sta~e of the nrt. Users are cautioned to check to determine fhag ihey

`Comments Nr revision nf IEEE Sta~dards are welcmne t~om any inl:created p~?rt.y, regard-

`to the attention of IENE, the Institute will initiate action te prepare appropriate responses.
`Since IEEN Standards represent a consensus of eli concerucd in~erea~s, i~ is important
`ensure fl~a~ any interpretation has also received the c~ncun’ence of a balance of interests. For
`tSia raagon IENE mid tim members of its technical cmnmittees are not able to provide
