ITU-T Recommendation 4.821.1 CORBA-based I“ alarm surveillance service Summary This Recommendation is part of a series of Recommendations
6、that specify the CORBA interface requirements for communication between an Operations System (OS) and a Network Element (NE), between an OS and a Mediation Device (MD), between an OS and a Q Adapter (QA), and between OSs in a Telecommunication Management Network (TMN). This Recommendation provides a
7、 Stage 2 and Stage 3 Description for Alarm Surveillance to support the associated TMN management service component described in ITU-T Rec. M.3400. In this Recommendation, both fine-grained and coarse-grained (i.e. facade) interfaces are defined for the alarm management functions. The fine-grained an
8、d facade interfaces provide the same support for alarm management. Both can be used with fine-grained and coarse-grained managed objects (e.g. those defined in IZTU-T Rec. M.3120). The primary purpose of this Recommendation is to provide a set of application messages and associated support objects f
9、or the support of communication across COMA interfaces. Because of the desirability of providing common TMN solutions, these messages and support objects are expected to be applicable to other TMN or TMN-related interfaces. Source ITU-T Recommendation Q.821.1 was prepared by ITU-T Study Group 4 (200
10、1-2004) and approved under the WTSA Resolution 1 procedure on 29 September 2001. ITU-T Rec. Q.821.1(09/2001) 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
11、) 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. The World Telecommunication Standardization Assembly (WTSA), which meets every four yea
12、rs, 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 1. In some areas of information technology which fall within ITU-Ts purview, the nece
13、ssary 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 recognized operating agency. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the
14、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 claimed Intellectual Property Rights, whether asserted by ITU members or others outside of
15、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 Recommendation. However, implementors are cautioned that this may not represent the latest in
16、formation and are therefore strongly urged to consult the TSB patent database. o ITU 2002 All rights reserved.

43、 Recommendation is part of a series of Recommendations that specify the CORBA interface requirements for communication between an Operations System (OS) and a Network Element (NE), between an OS and a Mediation Device (MD), between an OS and a Q Adapter (QA), and between OSs in a Telecommunication M
44、anagement Network (TMN) i. This Recommendation provides a Stage 2 and Stage 3 Description 5 for Alarm Surveillance to support the associated TMN management service component described in ITU-T Rec. M.3400 4. In this Recommendation, both fuie-grained and coarse-grained (i.e. facade) interfaces are de
45、fined for the alarm management functions. The fine-grained and facade interfaces provide the same support for alarm management. Both can be used with fine-grained and coarse-grained managed objects (e.g. those defined in ITU-T Rec. M.3120). Current telecommunications networks are populated by a larg
46、e and increasing number of OSs and network elements supplied by different vendors. Both the number and variety of networks and services have grown, creating a diversity of management needs. This growth has resulted in the proliferation of unique communication interfaces between OSs and network eleme
47、nts. The telecommunications industry stands to benefit from the standardization of these interfaces, designed to achieve interoperability between a broad range of OSs and network elements/Q Adapters, using Mediation Devices where appropriate, and between OSs. The primary purpose of this Recommendati
48、on is to provide a set of application messages and associated support objects for the support of communication across CORBA interfaces. Because of the desirability of providing common TMN solutions, these messages and support objects are expected to be applicable to other Th4N or TMN-related interfa
49、ces. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
