2、on K.48 EMC requirements for telecommunication equipment Product family Recommendation Summary This Recommendation specifies the emission and immunity requirements for switching, transmission, power, digital mobile base station, wireless LAN, digital radio relay system, digital subscriber line (xDSL
3、) and supervisory equipment. It also describes operational conditions for emission and immunity testing. Performance criteria for immunity tests are also specified. Source ITU-T Recommendation K.48 was approved on 22 September 2006 by ITU-T Study Group 5 (2005-2008) under the ITU-T Recommendation A.
4、8 procedure. ii ITU-T Rec. K.48 (09/2006) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying tech
5、nical, operating and tariff questions and issuing 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,
6、 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 fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IE
7、C. 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 Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to en
8、sure 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 such as “must“ and the negative equivalents are used to express requirements. The use of such words does
9、 not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY 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
10、 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 approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents
11、, 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 patent database at http:/www.itu.int/ITU-T/ipr/.

K.48 (09/2006) 1 ITU-T Recommendation K.48 EMC requirements for telecommunication equipment Product family Recommendation 1 Scope This Recommendation specifies the emission and immunity requirements for switching,
18、transmission, power, digital mobile base station, wireless LAN, digital radio relay system, digital subscriber line (xDSL) and supervisory equipment. It also describes operational conditions for emission and immunity testing. Performance criteria for immunity tests are also specified. The general op
19、erational condition and performance criteria are recommended in ITU-T Rec. K.43. This Recommendation describes the specific testing conditions to be applied to telecommunication network equipment. 2 References The following ITU-T Recommendations and other references contain provisions which, through
20、 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 applying the
