38、e support of aspects of planning, operating and maintaining the network being managed, always described from the user perception of management requirements. Each TMN management service has been described using Task O and Task 1 of the TMN methodology described in ETR 048 1181. The main goal of this
39、methodology is to provide the description of the object models and interfaces requirements supporting the management activities. Task O provides the prose description of the TMN management service itself and of the TMN management service components. These are the constituent parts of the TMN managem
40、ent service, triggering the actions to be performed on the management network. The TMN managernent service components correspond to the parts of the TMN management service that are visible to the user. Task 1 provides the list of TMN management functions. These are the management capabilities suppor
41、ting the TMN management service, as perceived by a user of such a service, and are presented as a sequenced set of actions on a defined managed object, or objects. The reader should note that when defining a management service it is advisable to take into account all available material that exists w
42、ithin current CCIlT and IS0 telecommunications standards. This information should ensure that a more thorough description is made of the management service under definition. An aid in the specification of management services may be to use a tool called “management services template“. The following t
43、ext describes the tool and its use. COPYRIGHT European Telecommunications Standards InstituteLicensed by Information Handling Services3404583 0067875 466 Page 11 ETR 047:1992 4.1 Template description In specifying a management service it is necessary to cover all functional areas to ensure that the
44、total functional requirements are addressed. The following text describes a tool called a management services template. The use of this tool helps to ensure complete coverage of the functional requirements of a management service. This is achieved by the relationship of the concepts contained within
45、 hierarchical management to all possible functional areas of management, e.g. performance management, fault management, accounting management, etc. A pictorial representation of the template is given in figure 1. The template is two-dimensional, the first dimension being the logical representation o
46、f an administrations management hierarchy and the second being a list of those functional areas to be covered. All of the resultant boxes within the template need to be addressed, although some may be redundant, depending on the specific management service being defined. It should be noted that the
47、template is only one example of a tool that may be used and it does not restrict the reader in implementing his, or her, own method of management service specification. 4.2 Method of use The following is a step-by-step procedure of the use of the template: 1) specify the management service; 2) work
48、consistently through each box of the template. The output from each of the boxes will be a list of the management service components which have been identified; 3) expand each component into its respective functions. As a result of the above procedure, it may be possible to identify specific objects
49、. The analysis of each of the objects will ensure that all functional specifications have been fully addressed and may result in further additions to the function list. As an aid to the reader, the expansion of one of the boxes is given in figure 2. It is not the intention of this ETR to identify managed objects, however, it is envisaged that this ETR, along with other ETRs on subjects such as the generic network model, may be used to identify those objects that will be under the control of a manager. To this end each of the management services listed will have a sp
