8、 DATA TRANSMISSION SERVICES CORRIGENDUM 1 Source Corrigendum 1 to ITU-T Recommendation X.75 was prepared by ITU-T Study Group 7 (1997-2000) and was approved by SG 7 at its Plenary on the 25th of September 1998. Recommendation X.75/Cor.l (09/98) 1 FOREWORD ITU (International Telecommunication Union)
9、is the United Nations Specialized Agency in the field of telecommuni- cations. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to
10、standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendation
11、s by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1, In some areas of information technology which fali within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Adminis
12、tration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Pro
13、perty Right. The 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 approval of this Recommendation, the ITU had not received
14、notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O ITU 1999 All rights reserved. N
