For example, common applications are described for date and time, fault management, configuration management, account management, performance management and securi
8、ty management. These applications result in the specification of common EMF functions and their requirements. The 2012 revision of this Recommendation has incorporated the following below.

ITU-T G.7710/Y.1701 (02/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field
13、 of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication 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 standardizin
14、g telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (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 b
15、y the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall 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 b
16、oth a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved whe
17、n all of these mandatory provisions are met. The words “shall“ or some other obligatory language 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 PROPERT
18、Y RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation 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
19、by ITU members or others outside of the Recommendation development process. As of the date of approval 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

ITU-T G.7710/Y.1701 (02/2012) 1 Recommendation ITU-T G.7710/Y.1701 Common equipment management function requirements 1 Scope This Recommendation specifies those equipment management fu
26、nction (EMF) requirements that are common to multiple transport technologies. Eventually this Recommendation will include all the common management functions. This Recommendation specifies the capabilities required no matter what technology and where there are differences in requirements for a given
27、 feature between technologies, the requirements will be specified in the technology-specific Recommendation. See Appendix I for an overview of common and technology-specific Recommendations. A future version of this Recommendation will elaborate on specific requirements within a given capability. It
28、 must be noted that for a network element (NE) it is not mandatory to support all described applications, and consequently not all 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
29、 technology-specific Recommendations. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
