2、 Fibre Channel Methodologies forSignal Quality Specification(FC-MSQS)SecretariatInformation Technology Industry CouncilAn ANSI Technical Report prepared by INCITS.AbstractThis technical report compiles and provides additional information beyond that supplied in FC-MJSQ toclarify the jitter and signa
3、l quality specification clauses of the relevant physical interfaces. It specifies bud-get methods for equalized and non-equalized links and specifies and describes methods of measurementfor links using a reference receiver. The technical report specifies test patterns for scrambled and un-scrambled
4、links. The technical report also specifies channel characteristics that have not been previouslyaddressed.This Technical Report is one in a series produced by the InternationalCommittee for Information Technology Standards (INCITS). The secretariatfor INCITS is held by the Information Technology Ind
5、ustry Council (ITI), 1101K Street, NW, Suite 610, Washington, DC 20005.As a by-product of the standards development process and the resources ofknowledge devoted to it, INCITS from time to time produces TechnicalReports. Such Technical Reports are not standards, nor are they intended tobe used as su
6、ch.INCITS Technical Reports are produced in some cases to disseminate thetechnical and logical concepts reflected in standards already published orunder development. In other cases, they derive from studies in areas whereit is found premature to develop a standard due to a still-changing technologyo
7、r inappropriate to develop a rigorous standard due to the existence of anumber of viable options, the choice of which depends on the users particularrequirements.These Technical Reports, thus, provide guidelines, the use ofwhich can result in greater consistency and coherence of informationprocessin
8、g systems.When the draft Technical Report is completed, the Technical Committeeapproval process is the same as for a draft standard. Processing by INCITSis also similar to that of a draft standard.INCITSTechnical ReportSeriesPublished byAmerican National Standards Institute, Inc.25 West 43rd Street,

However, neither the developers nor the publisher have undertaken a
11、 patent search in orderto identify which, if any, patents may apply to this Technical Report. As of the date of publication ofthis Technical Report, following calls for the identification of patents that may be required for theimplementation of the standard, notice of one or more such claims has bee
12、n received. By publica-tion of this Technical Report, no position is taken with respect to the validity of this claim or of anyrights in connection therewith. The known patent holder(s) has (have), however, filed a statementof willingness to grant a license under these rights on reasonable and nondi
13、scriminatory terms andconditions to applicants desiring to obtain such a license. Details may be obtained from the pub-lisher. No further patent search is conducted by the developer or publisher in respect to any Tech-nical Report it processes. No representation is made or implied that this is the o
14、nly license thatmay be required to avoid infringement in the use of this Technical Report.iContents1.
