Source Corrigendum 1 to ITU-T Recommendation X.735 was prepared by ITU-T Study Group 4 (2001-2004) and approved on 1 March 2001. An identical text is also published

9、as Technical Corrigendum 1 to ISO/IEC 10164-6. ii ITU-T X.735 (1992)/Cor.1 (03/2001 E) 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 o

10、f 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, establishes the topi

11、cs 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 standards are prep

12、ared on a collaborative basis with ISO 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 that the pra

13、ctice 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 Recommendation devel

14、opment 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 and are theref

15、ore strongly urged to consult the TSB patent database. ITU 2002 All rights reserved.

17、NTROL FUNCTION TECHNICAL CORRIGENDUM 1 1) Subclause 8.1.1.1.5 “Log Full Action“ Add the following to the end of the subclause: When a log is full its availability status will change to indicate the log full condition. If the logs full action is set to “halt“, then no new log records will be added an

18、d the event will be lost. When log records are deleted, the log will leave the log full condition and new log records can be added to the log. If the logs full action is set to “wrap“, then new records will be added overwriting the oldest records contained in the log. When log records are deleted, t

19、he log will leave the log full condition and new log records will no longer overwrite existing log records in the log. 2) Subclause 8.1.1.1.6 “Availability status“ Replace the second sentence: The attribute may indicate a “log-full“ condition; indicating that records can be retrieved but that no new

20、 records can be added. with the following: The attribute may indicate a “log-full“ condition. Records can be retrieved while the log is in the “log-full“ condition. If records are deleted from the log, the “log-full“ value is removed from the availability status in either halt or wrap mode. NOTE In

21、the case where halt behaviour is specified for the log, the “log-full“ value implies no more records can be added. If wrap behaviour is specified, the value continues to remain as “log-full“ even though forthcoming records will be added by overwriting existing records. The wrap mode combined with “l

22、og-full“ condition indicates that old records are lost as overwriting takes place. 3) Subclause 8.1.1.5 “Normal operation of logs“ Add the following Note at the end of the subclause: NOTE A wrapping log can be viewed as a circular buffer. The margin between the highest capacity alarm threshold and 1

23、00% can be regarded as a safety factor, to allow sufficient time for log users to retrieve log records upon receipt of a capacity alarm, before those records which entered the log after the previous capacity alarm are overwritten. Resetting the hidden gauge to zero each time the highest threshold is

24、 crossed ensures the behaviour that a capacity alarm will be generated every time the same fraction of the log capacity is written to the log, and therefore the same safety factor is maintained. In other words, every time a fixed percentage of the log capacity is written to the wrapping log, a capac

25、ity alarm is emitted.
