4、n Technology Industry Council Approved August 9, 2007 American National Standards Institute, Inc. Abstract This amendment to standard ANSI INCITS 424-2007 (Fibre Channel - Framing and Signaling - 2) describes the incremental framing and signaling requirements for scrambling frames on Fibre Channel l
5、inks. This amendment is relevant to implementations of Fibre Channel links for which the Fibre Channel - Physical Interfaces - 4 (FC-PI-4) standard recommends or requires Frame Scrambling. It augments but does not replace existing Fibre Channel standards. Copyright American National Standards Instit

Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means mu

The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of
10、any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appear
