ITU-T Recommendation X.790 Trouble management function for ITU-T applications CORRIGENDUM 2 Summary These changes are necessary to correct defects in Corrigendum 1, thus they reference the “Sn“ labelled inde
8、xes fi-om ITU-T X.790 (Cor. 1). Source Corrigendum2 to ITU-T Recommendation X.790 was prepared by ITU-T Study Group4 (2001-2004) and approved under the WTSA Resolution 1 procedure on 1 March 2001. FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in th
9、e field of telecommunications. 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 telecommunications on a worldwide basis. T
10、he 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 procedure laid down in WTSA Resolution
11、 1. In some areas of information technology which fall within IT-Ts purview, the necessary standards 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
12、recognized operating agency. 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 the evidence, validity or applicability of claime
13、d Intellectual Property Rights, whether asserted by IT 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 Recommend
14、ation. 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 2001 All rights reserved.

ITU-T Recommendation X.790 Trouble management function for ITU-T applications CORRIGENDUM 2 1) Nature of defect: This changes TroubleFound to add a noTroubleFoundValue. However it also incorrectly leaves the extens
16、ibility marker (.) at the end of the number component. An ASN.l INTEGER is inherently extensible, so the . marker is not valid. The end of the replucement text should look like: Reference in Corrigendum 1 : The second change (3.27.2 S2) referredout (59), network (60) identifier OBJECT IDENTIFIER, no
17、TroubleFoundValue 1, NULL, - used when TroubZeFound not relevant - (This fix is reflected in 3.27.17 S17.) 2) Nature of defect: Provides incorrect values to the several initial values, since the relevant types are SET OF SEQUENCE. Reference in Corrigendum 1: The sixth change (3.27.6 S6), item 3 repa
18、irActivityListRepairActivityListInitia1 RepairActivityList:= - EMPTY SEQUENCE should be changed to: repairActivityListRepairActivityListInitia1 RepairActivityList: := - EMPTYSET OF and activityDurationactivityDuarationInitia1 ActivityDuration:= - EMPTY SEQUENCE should be changed to: activityDuration
19、activityDuarationInitia1 ActivityDuration: := - EMPTY SET OF 3) Nature of defect: Adds references to DMI attributes. Need to use the “full“ name of DMI, rather than “Rec. X.72 1 : 1992“. Reference in Corrigendum 1 : The seventh change (3.27.7 S7) “Rec. X.721: 1992 “:managedObj ectInstance should be
20、changed in two places to: “CCITT Rec.

Changes to Corrigendum 1 text: 1) remove Activ
21、ityInfo from list. 2) add HandofiTime to list. 5) Reference in Corrigendum 1: The nineteenth change (3.27.19 S19) Nature of defect: Adds identifiers to most types, but fails to cover WeekMask. Change to: WeekMask:=SEQUENCE daysofweek BIT STRING sunday (O), monday (i), tuesday (2), Wednesday (3), thu
