2、ved July 5, 2007 American National Standards Institute, Inc.AbstractThis standard describes the Link Services requirements. The Physical Interface requirements are de-scribed in Fibre Channel-Physical Interfaces - 2 (FC-PI-2). The Framing and Signaling requirements aredescribed in Fibre Channel-Phys
3、ical Framing and Signaling - 2 (FC-FS-2). This standard is recommend-ed for 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 criteria for approva
4、l 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 necessarily unanim
5、ity. 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 or not, from ma
6、nufacturing, 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 shall have the
7、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: This American Nati
8、onal Standard may be revised orwithdrawn at any time. The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, orwithdraw this standard. Purchasers of American National Standards mayreceive current information on all standards by calli

However, nei-ther the developers nor the publisher have undertaken a patent search in order to identify which, ifany, patents may apply to this standard. As of the date of publication of this standard, followingcalls for the identific
12、ation of patents that may be required for the implementation of the standard,notice of one or more such claims has been received. By publication of this standard, no positionis taken with respect to the validity of this claim or of any rights in connection therewith. The knownpatent holder(s) has (h
13、ave), however, filed a statement of willingness to grant a license underthese rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to ob-tain such a license. Details may be obtained from the publisher. No further patent search is con-ducted by the developer or publi

No representation ismade or implied that this is the only license that may be required to avoid infringement in the use ofthis standard.iContentsPageForeword .ixIntroduction xii1 Scope. 12 Normative References . 12.1 Overview. 12.2 Approved references. 1
