10、 the United Nations specialized agency in the field 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

11、Recommendations on them with a view to standardizing 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.

12、 The approval of ITU-T Recommendations is covered by 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 “Ad

13、ministration“ is used for conciseness to indicate both 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

14、 compliance with the Recommendation is achieved when 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 Recommenda

15、tion is required of any party. INTELLECTUAL PROPERTY RIGHTSITU 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 claim

16、ed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendat

17、ion. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

23、tworking technologies under the abstraction layer defined by 1905 technology (see IEEE 1905.11a 2014). The IEEE 1905.1 standard defines an abstraction layer for multiple home networking technologies, which presents a common virtual interface (the 1905 MAC SAP) to upper layers for the underlying netw

24、orking technologies below the relevant 1905.1 Interface SAP(s). As indicated in clause 1.1 of the IEEE 1905.1 standard, 1905 is extensible to work with network technologies not included in the original standard. This Recommendation makes use of the generic extension mechanism described in IEEE 1905.

25、1a to specify an extension to the IEEE 1905.1 standard that introduces the ITU-T G.996x and ITU-T G.9954 network technologies as additional underlying network interfaces for the 1905 abstraction layer. 2 References The following ITU-T Recommendations and other references contain provisions which, th
