Thi
7、s Recommendation also describes the relationship among the three architectures and provides a fi-amework to derive the requirements for the specification of TMN physical architectures fi-om the TMN functional and information architectures. A logical reference model for partitioning of management fun

Source ITU-T Recommendation M.3010 was revised by ITU-T Study Group 4 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on 4 February 2000.

9、odel, telecommunications management network (TMN). Recommendation M.3010 (02/2000) i FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the
10、ITU. The 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, establishes the
11、topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purvi
12、ew, 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 recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws a
13、ttention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members o
14、r others outside of the Recommendation development process. As of the date of approval of this Recommendation, the 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
15、 represent the latest information and are therefore strongly urged to consult the TSB patent database. o ITU 2000 All rights reserved.

Definitions This Recommendation defines the following terms: 3.1 business management layer: A management layer responsible for the total enterprise and not subject to standardization. 3.2 data communicatio
39、n network: A communication network within a TMN or between TMNs which supports the data communication function (DCF). 3.3 element management layer: A management layer which is responsible for management of network elements on an individual or collective basis. 3.4 F interface: An interface applied a
40、t f reference points. 3.5 f reference points: A reference point that is located between the workstation function block (WSF) and the operations systems function block (OSF). 3.6 function block: The smallest (deployable) unit of TMN management functionality that is subject to standardization. 3.7 g r
41、eference points: A reference point located outside the TMN between the human users and the workstation function block (WSF). It is not considered to be part of the TMN even though it conveys TMN information. 3.8 interface: An architectural concept that provides interconnection between physical block
42、s at reference points. 3.9 logical layered architecture: An architectural concept that organizes the management functions into a grouping of management layers and describes the relationship between the layers. 3.10 m reference points: A reference point located outside the TMN between a Q adapter fun
43、ction block (QAF) and managed entities that do not conform to TMN Recommendations. 2 Recommendation M.3010 (02/2000) 3.11 managed resource: The abstraction of those aspects of a telecommunication resource (logical or physical) required for telecommunications management. 3.12 management application f
44、unction: A function that represents (part of) the functionality of one or more management services. 3.13 management domain: A set of managed resources subject to a common management policy. 3.14 management function: The smallest part of a management service as perceived by the user of the service. 3
45、.15 management function set: TMN management function set is a grouping of TMN management functions that contextually belong together, i.e. they are related to a specific management capability (e.g. alarm reporting functions, traffic management control). The TMN management function set is the smalles
46、t reusable item of functional specification. The TMN management function set must be considered as a whole. It is similar to the requirements part of the OS1 SMF (system management function). 3.16 management layer: An architectural concept that reflects particular aspects of management and implies a
47、 clustering of management information supporting that aspect. 3.17 management service: A management service is an offering fulfilling specific telecommunications management needs. 3.18 network element: An architectural concept that represents telecommunication equipment (or groups/parts of telecommu
48、nication equipment) and supports equipments or any item or groups of items considered belonging to the telecommunications environment that performs network element functions (NEFS). 3.19 network element function: A function block which represents the telecommunication functions and communicates with
49、 the TMN OSF function block for the purpose of being monitored and/or controlled. 3.20 network management layer: A management layer responsible for the management, including coordination of activity, of a network view. 3.21 operations system: A physical block which performs operations systems functions (OSFs). 3.22 operations systems function: A function block that processes information related to the telecommunications management for the purpose of monitoring/coordinating and/or controlling telecommunication functions including management functions (i.e. the TMN itself). 3.23 physical block
