The Enhanced Telecom Operations Map(or eTOM for short), which has
7、been developed by the TeleManagement Forum, describes the enterprise processes required by a service provider and analyses them to different levels of detail according to their significance and priority for the business. This business process approach has built on the concepts of Management Services
8、 and Functions in order to develop a framework for categorizing all the business activities. This Supplement provides an insight on how the functional view provided by the Management Functions described in TMN Recommendation M.3400 can be mapped to the process view provided by the eTOM Business Proc

The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsib
11、le 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 topics for study by the ITU-T
12、 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 prepared on a collaborative b

23、 1 Scope The Enhanced Telecom Operations Map (eTOM) 4 has been developed by the TeleManagement Forum as a reference framework for categorizing all the business activities that an Information and Communications service provider will use. It should be noted that the TM Forum retains the ownership of t
24、he eTOM and copyright of the underlying IPR. The ITU-T will own the copyright on the M.3050.x series ITU-T Recommendations themselves.

27、es of ITU-T Recs M.3050.x build on the Management Services approach described in ITU-T Recs M.3010 and M.3200 by developing a Business Process Framework. This Supplement provides an insight on how the functional view provided by the Management Functions described in TMN Recommendation M.3400 1 can b
28、e mapped to the process view provided by the eTOM Business Process Framework. The eTOM provides the framework for standardizing and categorizing business activities to help setting the direction for management solutions. It also provides the business-oriented view of service provider requirements th
29、at the management services and functions will need to support. The mapping of eTOM processes to M.3400 management functions in both directions is documented in this Supplement, in order to facilitate the application of both these processes and functions within the development and integration of Busi

33、ons are additional to those defined in ITU-T Rec. M.3050.1: NGN Next Generation Network OSI Open Systems Interconnection TM Forum TeleManagement Forum (see also TMF) 4 Linking eTOM to the TMN model Within the telecommunications industry different Management Models have evolved over time. The OSI Fun
34、ctional model the Service Management Function Areas introduced the functional areas known as FCAPS: Fault Management, Configuration Management, Accounting Management, Performance Management and Security Management. The ITU-T TMN introduced the concept of the Logical Layered Architecture with the Ele
35、ment Management Layer, Network Management Layer, Service Management Layer and Business Management Layer. This is one of the concepts that have been developed by ITU, to assist in the functional decomposition of the management requirements into manageable subsets and to encourage the reuse of solutio
36、ns, as is described in ITU-T Rec. M.3050.0 4. As investment decisions in the telecommunications industry were more and more driven by Business rather than Technology drivers, the TeleManagement Forum developed the Enhanced Telecom Operations Map (eTOM) as a reference framework for classifying all bu
37、siness activities, which will be performed by an Information and Communications service provider. Process elements components of overall business processes can be positioned within a model to show organizational, functional and other relationships, and can be combined within process flows that trace
38、 activity paths through the business. The eTOM concepts are described in ITU-T Rec. M.3050.1 5. ITU-T Rec. M.3050/Suppl.3 (05/2004) 3 This clause links the ITU-TMN model and the eTOM Business Process Framework, business drivers and the benefits we can get from linking those two models. It should be
39、noted that in the context of the eTOM Business Process Framework, Process Elements are the building blocks or components, which are used to assemble end-to-end business processes. The term Process refers to a systematic, sequenced set of functional activities that deliver a specified result, and doe
40、s not refer to Process Flow, which is the sequencing of Process Elements (see 5). 4.1 The TMN model The telecommunications industry has embraced the Telecommunications Management Network (TMN) model as a way to think logically about how the business of a service provider is managed. As mentioned bef
41、ore, the TMN model introduced the concept of Logical Layered Architecture. It consists of four layers, usually arranged in a triangle or pyramid, with business management at the apex, service management the second layer, network management the third layer, and element management at the bottom. The i
42、dea is that management decisions at each layer are different but interrelated. For example, detailed information is needed to keep a switch operating (at the element management layer), but only a subset of that information is needed to keep the network operating (e.g., is the switch operating at ful
43、l capacity). Working from the top down, each layer imposes requirements on the layer below. Working from the bottom up, each layer provides a capability to the layer above.

44、hitecture model Some of the concepts defined by the TMN are very relevant for the context of this Supplement. ITU-T Rec. M.3200 3 describes Telecommunications Managed Areasand TMN Management Services, in order to support the wide variety of management activities for telecommunications networks and s
45、ervices. The Telecommunications Managed Areasrelate to the grouping of telecommunications resources being managed and the Management Services relate to the set of processes needed to achieve business objectives (Management Goals). It has been accepted that flexibility is required in the definition o
46、f TMN Management Services to enable additional requirements to be accommodated as they are identified 3. The management services are comprised of management functions, where Management Functions are grouped together and referred to as a Management Function Set. ITU-T Rec. M.3400 1 states that “A TMN
47、 Management Function is a cooperative interaction between application processes in managing and managed systems for the management of telecommunications resources, and is the smallest functional part of a TMN Management Service as perceived by the TMN users“. The library of general Management Functi
48、on Sets and their Management Functions members can be found in ITU-T Rec. M.3400 1 categorized according to their FCAPS application. 4 ITU-T Rec. M.3050/Suppl.3 (05/2004) In describing the requirements for an interface, the functions identified may reference those defined in ITU-T Rec. M.3400 1 or s
49、pecialize one or more of them to suit a specific managed area, or new functions may be identified as appropriate. The TMN model is simple, although its implementation is complex. The sheer number of standards now available that address the various interfaces between management systems makes it difficult to see and appreciate the big picture. These ITU-T standards are mainly concentrated in the element management and network management layers. Although they have been develope
