7、016) i Recommendation ITU-T G.7710/Y.1701 Common equipment management function requirements Amendment 1 Summary Recommendation ITU-T G.7710/Y.1701 addresses the equipment management functions (EMFs) inside a transport network element that are common to multiple technologies. For example, common appl
8、ications are described for date and time, fault management, configuration management, account management, performance management and security management. These applications result in the specification of common EMF functions and their requirements. The 2012 revision of this Recommendation has incorp
9、orated the following below. Recommendation ITU-T G.7710/Y.1701 Corrigendum 1 (11/2009): this mainly contains an updated equipment management function process block diagram. Recommendation ITU-T G.7710/Y.1701 Amendment 1 (07/2010): updates the packet layer related specification of severely errored se
10、cond (SES) to align it with the SES definition in Recommendation ITU-T Y.1563. Recommendation ITU-T G.7710/Y.1701 Corrigendum 2 (04/2011): this adds the missing 6 LBC terms to the process description, and gives additional specifications on gauge measurement. Amendment 1 provides updates to: Clause 3

ITU-T G.7710/Y.1701 (2012)/Amd.1 (11/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunica
16、tion Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly
17、(WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fa
18、ll within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this R
19、ecommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language
20、 such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recom
21、mendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of app
22、roval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB

Modifications introduc
29、ed by this amendment are shown in revision marks relative to Recommendation ITU-T G.7710/Y.1701 (2012). 1 Scope This Recommendation specifies those equipment management function (EMF) requirements that are common to multiple transport technologies. Eventually this Recommendation will include all the
30、 common management functions. This Recommendation specifies the capabilities required no matter what technology and where there are differences in requirements for a given feature between technologies, the requirements will be specified in the technology-specific Recommendation. See Appendix I for a
31、n overview of common and technology-specific Recommendations. A future version of this Recommendation will elaborate on specific requirements within a given capability. It must be noted that for a network element (NE) it is not mandatory to support all described applications, and consequently not al
32、l specified functions. Depending on the position in the network, the NE may support a subset of the functions. Packages with subsets of these functions can be found in the technology-specific Recommendations. 2 References The following ITU-T Recommendations and other references contain provisions wh
33、ich, through reference in this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of
34、applying the most recent edition of the Recommendations and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published.
