8、TION TECHNICAL CORRIGENDUM 2 Summary This Recommendation I International Standard (1995) provides a model for characterizing the relationship between resources in terms of the way one or more resources may provide a back-up role for other resources. This includes the hot/cold standby concept and the
9、 associated aspects of primary and secondary back-up. This Technical Corrigendum 2 revises the text to include ASN.l: 1997 in 2.1, 2.2 and 13.1. Source Corrigendum 2 to ITU-T Recommendation X.751 was prepared by ITU-T Study Group 4 (1997-2000) and approved on 4 February 2000. An identical text is al
10、so published as Technical Corrigendum 2 to ISO/EC 10164-17. ITU-T X.751(1995)/Cor.2 (02/2000 E) 1 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 perman
11、ent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establi
12、shes 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 procedure laid down in WTSC Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary stand
13、ards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility
14、 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 ITU members or others outside of the Recomme
15、ndation 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, implementors are cautioned that this may not represent the latest information a
16、nd are therefore strongly urged to consult the TSB patent database. o mu 2001 All rights reserved, No part of this publication may be reproduced or utilized in any form or by any means, electronic or mechanical, including photocopying and microfilm, without permission in writing from ITU. 11 ITU-T X
