ITU-T Recommendation V.59 Managed objects for diagnostic information of public switched telephone network connected V-series modem DCEs Corrigendum 2 Source Corrigendum2 to ITU-T Recommendation V.59 was prepared by ITU-T Study Group 16 (2001-2004) and
5、 approved under the WTSA Resolution 1 procedure on 29 March 2002. ITU-T Rec. V.59Kor.2 (03/2002) i 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 perma
6、nent 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 Assembly (WTSA), which meets every four years, establis
7、hes 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 WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standa
8、rds 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
9、that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Propery 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 Recommend
10、ation 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 Recommendation. However, implementors are cautioned that this may not represent the latest information and are
11、 therefore strongly urged to consult the TSB patent database. o ITU 2002 All rights reserved.

V.59 and ASN. 1 Text intended to clari
14、fj any conflict between the text of ITU-T Rec. V.59 and the ASN.l definitions in Annex A was erroneously omitted. The intent has always been to follow the example of other Recommendations that use ASN. 1. The following sentence is to be added to the end of the final paragraph of clause 5 just prior
15、to 5.1 : “In the case of a conflict between the ASN.l and the text, the ASN.1 governs.“ ORIGINAL TEXT The presentation of the managed objects within this Recommendation complies with the specification of ASN.l (see ITU-T X.680). The ASN.l as defined in Annex A should be used in conjunction with the
16、object definitions to provide a complete overview of the diagnostics. The ASN.l encoding in Annex A should employ the BASIC-ALIGNED version of Packed Encoding Rules (PER) according to ITU-T X.69 1. END ORIGINAL REPLACEMENT TEXT The presentation of the managed objects within this Recommendation compl
17、ies with the specification of ASN.1 (see ITU-T Rec. X.680). The ASN.l as defined in Annex A should be used in conjunction with the object definitions to provide a complete overview of the diagnostics. The ASN.l encoding in Annex A should employ the BASIC-ALIGNED version of Packed Encoding Rules (PER
18、) according to ITU-T Rec. X.691. In the case of a conflict between the ASN.l and the text, the ASN.l governs. END REPLACEMENT 2) The following list of diagnostic objects are defined as not mandatory in 6.13, but are not indicated as being optional in the ASN.l: txThroughput, mThroughput, txErrors an
19、d mErrors in the DTE DCE high-level object set. Since these are all derived objects, they are to be defined as optional. Consequently, the ASN.1 in Annex A should be modified accordingly.
