2、try CouncilApproved December 27, 2016American National Standards Institute, Inc.AbstractThis standard describes the framing and signaling requirements for Fibre Channel links. The PhysicalInterface requirements are described in Fibre Channel-Physical Interfaces (FC-PI-x). The Link Servicesrequiremen
3、ts are described in Fibre Channel-Link Services (FC-LS-3). This standard is recommendedfor new implementations but does not obsolete the existing Fibre Channel standards.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other crite
4、ria for approval havebeen met by the standards developer.Consensus is established when, in the 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 nec
5、essarily unanimity. Consensus requires that allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of American National Standards is completely voluntary; theirexistence does not in any respect preclude anyone, whether he has approvedthe standards
6、or not, from manufacturing, marketing, purchasing, or usingproducts, processes, or procedures not conforming to the standards.The American National Standards Institute does not develop standards andwill in no circumstances give an interpretation of any American NationalStandard. Moreover, no person
7、shall have the right or authority to issue aninterpretation of an American National Standard in the name of the AmericanNational Standards Institute. Requests for interpretations should beaddressed to the secretariat or sponsor whose name appears on the titlepage of this standard.CAUTION NOTICE: Thi
