3、onnel or it may be accessed via other applications (e.g., an SMI-S Client).Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the
4、judgement of the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a c

44、s, events, states, orsimilar terms are printed with the first letter of each word in uppercase and the rest lowercase (e.g.,Exchange, Class). Any lowercase uses of these words have the normal technical English meanings.Lists sequenced by letters (e.g., a-red, b-blue, c-green) show no ordering relati
45、onship between thelisted items. Numbered lists (e.g., 1-red, 2-blue, 3-green) show an ordering between the listed items.ANSI INCITS 443-20085The ISO convention of numbering is used (i.e., the thousands and higher multiples are separated bya space and a comma is used as the decimal point.) A comparis
46、on of the American and ISO con-ventions are shown in table 1.In case of any conflict between figure, table, and text, the text, then tables, and finally figures takeprecedence. Exceptions to this convention are indicated in the appropriate sections.In all of the figures, tables, and text of this doc
47、ument, the most significant bit of a binary quantity isshown on the left side. Exceptions to this convention are indicated in the appropriate sections.When the value of the bit or field is not relevant, x or xx appears in place of a specific value.Numbers that are not immediately followed by lower-c
48、ase b or h are decimal values.Numbers immediately followed by lower-case b (xxb) are binary values.Numbers or upper case letters immediately followed by lower-case h (xxh) are hexadecimal values.3.4 Abbreviations, acronyms and symbolsAbbreviations and acronyms applicable to this standard are listed.
