7、 (OFDM) power line communication transceivers for communications via alternating current and direct current electric power lines over frequencies in the CENELEC A band. This Recommendation uses material from Recommendations ITU-T G.9955, ITU-T G.9956 and ITU-T G.9956 Amendment 1; specifically using
8、material from Annex B of ITU-T G.9955, Annex B of ITU-T G.9956 and ITU-T G.9956 Amendment 1. New technical material has not been introduced in this version. The control parameters that determine spectral content, power spectral density (PSD) mask requirements and the set of tools to support the redu

ITU-T G.9904 (10/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of t
10、elecommunications, 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 standardizing tel
11、ecommunications 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 by the
12、 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 both a
13、 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 when all
14、 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 PROPERTY RIG
15、HTS 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 by IT
16、U 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 this
