3、ich work towardsstandardized management interfaces may proceed. As the initial steps in this methodology it is necessary to investigate theservices which the users management applications will be expected to support and the functions necessary to support theseservices. The results of this investigat

4、ion will guide the detailed work on the interfaces identified in ECMA TR/54.The content of this Technical Report, ECMA TR/67, has been based upon a snapshot of the work of ETSI NA4.3 and ITU-TQ23/4 for the services description and for the functions to support these services (these services and funct

5、ions have beenadapted to suit the PTN environment). The services are not to be standardized and the compendium provided in this TechnicalReport does not attempt to be exhaustive in its coverage. Instead it explores sufficient material to assist further standardizationwork.This Technical Report has b

As a consequence of this, CCITT is nowreferred to as ITU-T except where a Recommendation being r

7、eferenced was produced under the CCITT name. The names ofStudy Groups also changed from Roman to Arabic numerals, and the Working Party number now comes before the StudyGroup number when referring to a specific Working Party, e.g. WP IV/3 now becomes WP3/4.This ECMA Technical Report has been adopted

40、cation network. As such it must be theaim of the management interfaces to support these requirements even if not all the services are provided by automatedequipment (e.g. the OMP or MP). The Management Services thus represent a marketing view.It is not envisioned that many new Management Services wi

41、ll be documented as they are currently enacted by humanoperators. These operators interact with the existing management systems so as to realise these Management Services.It must be an aim of standardization to allow for the continuing automation of these services so as to enhance theefficiency of t

42、he human operators.For consideration when identifying Management Services is that such services are relevant to specific areas in themanagement hierarchy, i.e. Business, Service, Network and Element Management. A human operator can interact witheach level in the hierarchy from a workstation and uses

43、 different Management Services from each level. This isdepicted in figure 1. For example, a maintenance engineer would want to interact at the Element Manager levelnormally and would need to see manageable objects in far more detail than would operators who are introducing newnetwork users.- 4 -Figu

44、re 1 - Workstation at different management levelsIn support of the above concept, a Management Service Template can be used to organise the categorization process.This is further described in annex A.Information is included in annex D about the interactions between the services, indicating overlaps,

45、 dependencies andinformation flows.6 GeneralManagement Services for PTNs have been defined based upon TMN Management Service work undertakenprincipally for public network equipment. This is because many management features/requirements are shared betweenpublic and private networks. The purpose of th

46、is compendium is to bring together in a single document an overview ofthe management services which are relevant to PTNs. Additional Management Services are defined which are requiredfor PTN Management where an equivalent TMN Management Service does not exist. Some of these additionalservices may al

47、so be adapted for use in public networks.The Functional Groupings have also been based upon work developed for TMN but have been simplified to separategeneric activities from the data involved. This has been done to ease the step to an object oriented specification whichis required for both PTN Mana

48、gement and TMN.Annexes have been provided to give more details of some of the additional Management Services, to show how TMNManagement services have been adapted and to give an overview of the major relationships between ManagementServices.7 Approach to Management ServicesEach Management Service th

49、at is listed represents a broad area of activity for PTN management. Each ManagementService is broken down into a set of Components of Service which represent the general activities that are required toenable the service to be offered.The management functions which are necessary to support each of these Components can be determined and newfunctions defined only if none suitable already exist. The functions are grouped for commonalty and rationalised thusavoiding potential duplications of effort.During the process of grouping and rationalisatio
