3、ded by ANSI/IEEE 1394a-2000 and ANSI/IEEE 1394b-2002.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 judgement of the ANSI

4、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 concerted effort be mad

38、.) by upper layer protocols such as operating sys-tems or embedded applications. Vendors that wish to implement devices that con-nect to Serial Bus may follow the requirements of this and other normativelyreferenced standards to manufacture an SBP-3 compliant device.There are ten annexes in this sta

39、ndard. Annexes A, B, C, D and E are normative andpart of this standard. Annexes F through J, inclusive, are informative and are not con-sidered part of this standard.Requests for interpretation, suggestions for improvement and addenda, or defect re-ports are welcome. They should be sent to the INCIT

40、S Secretariat, Information Tech-nology Industry Council, 1250 I Street NW, Suite 200, Washington, DC 20005-3922.This standard was processed and approved for submittal to ANSI by InterNationalCommittee for Information Technology Standardization (INCITS). Committee approv-al of this standard does not

41、necessarily imply that all committee members voted forapproval.

Although SBP-3 has been designed for Serial Bus

46、as currently specified by IEEE 1394, the Technical Committee anticipates that it will be appropriate for use with future extensions to Serial Bus as they are standardized.
