2、Technology Industry Council , Approved November 14, 1994 American National Standards Institute, Inc. Abstract This standard describes the point-to-point physical interface, transmission protocol, and signaling protocol of a high-performance serial link for support of the higher level protocols assoc
3、iated with HIPPI, IPI, SCSI, IP, and others. American Approval of an American National Standard requires verification by ANSI Nat i 0 n al that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Standard c onsensus is established wh
4、en, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered
5、, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processe
6、s, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an America
7、n National Standard in the name of the American National Standards Institute. Requests for interpretations should be ad- dressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any tim
8、e. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards In
9、stitute. CAUTION: The developers of this standard have requested that holders of patents that may be required for the implementation of the standard disclose such patents to the publisher. However, nei- ther the developers nor the publisher have undertaken a patent search in order to identify which,
10、 if any, patents may apply to this standard. As of the date of publication of this standard, following calls for the identification 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 positio
11、n is taken with respect to the validity of this claim or of any rights in connection therewith. The known patent holder(s) has (have), however, filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and condi- tions to applicants desiring to
12、obtain such a license. Details may be obtained from the publisher. No further patent search is conducted by the developer or publisher in respect to any standard it pro- cesses. No representation is made or implied that this is the only license that may be required to avoid infringement in the use o
