8、(ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and
9、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 study groups which, in turn, produce Recommendations on these
10、 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 basis with ISO and IEC. NOTE In this publication, the expressio

The syntax of
18、 these data needs to be communicated over data communication interfaces to other management applications within one operator or within other companies, or to the network or service platform. External terminology schemas define identifiers, name spaces, name bindings and other data that are efficient
19、 in use to the end users. This may lead to new object classes and relations between object classes as compared to a pure conceptual approach. Hence, conceptual definitions of the information conveyed by these interfaces are not sufficient, as data syntax requirements may lead to additions and modifi
20、cations of the conceptual definitions. The set of external terminology schemas is a resource of data definitions to be shared in telecommunication management applications. External terminology schemas define data used at the human-computer interfaces (HCI) and to be communicated over data communicat
21、ion interfaces. External terminology schemas do not define these interfaces. However, ITU-T Z.601, Data Architecture, indicates how external terminology schema definitions relate to the interface definitions. External terminology schemas define the terminology and grammar of end users at their HCI.
22、The terminology and grammar used for communication over data communication interfaces using a particular technology are defined in an internal terminology schema. Future Recommendations may provide a mapping between these schemata, but such a mapping is not provided in this supplement. This mapping
23、may or may not be provided via an intermediate concept schema. External terminology schemas are common for a set of user functions, data communication interfaces, and processes supported by management applications. Hence, the Directory of external terminology schemas will not have separate Recommend
24、ations for each of these. In summary, the following requirements apply to this directory: R1 External terminology schemas shall define data for end user interfaces and support but do not define data communication interfaces. R2 The use of external terminology schemas with respect to information mode
25、ls, e.g., b-ITU-T M.3100-neutral, shall be defined. (See Appendix I, Business needs.) R3 The use of external terminology schemas with respect to b-ITU-T M.3050.x shall be defined. (See Appendix I.) R4 The use of external terminology schemas within the ITU-T M.3020 methodology shall be defined. (See
26、clause 5, Rationale.) 2 References ITU-T M.1401 Recommendation ITU-T M.1401 (2006), Formalization of interconnection designations among operators telecommunication networks.

30、grammar across operators. The notion of a grammar may be elaborated a bit. It does not mean only definition of terms, but it specifies what terms may appear together to make up a statement. In short, a statement is a connected path through a schema graph. Also, in external terminology schemas, the t
31、erms are not defined independently of the grammar. The terms are defined within the grammar, and some terms act as name spaces for other terms. External terminology schemas define the abstract syntax of data, such that two terminal users in different operating companies communicating via different m
32、anagement applications should be able to understand each other also when having manual communication of the same data. The end user at his/her terminal is the ultimate user of external terminology schemas. However, designers will have to use external terminology schemas in order to meet the needs of
33、 the end user. ITU-T Z.601 provides a framework for positioning external terminology schemas and related Recommendations. Appendix III of b-ITU-T M.3020 places the external terminology schemas and the related Recommendations into this framework in the Requirement phase of b-ITU-T M.3020. ITU-T Z.601
34、 depicts specifications for various interfaces by seven kinds of schemata. Annex A of ITU-T Z.601 provides a set of numbered Requirements on the various schemata in the data architecture. ITU-T Z.601 explains how data can be transformed between the human-computer interface (HCI) and data communicati
35、on interfaces. The business need of the external terminology schemas is the need to harmonize end user terminology and grammar across various HCIs, which cannot be accomplished by standardizing concepts in a conceptual specification. 6 Directory of external terminology schemas This clause identifies
36、 the components of the Directory of external terminology schemas and outlines their contents and interrelationships. M series Supplement 7 (05/2008) 3 6.1 The relevant Recommendation set Directory of external terminology schemas (Supplement to the M-series Recommendations) The intention of the Direc
37、tory of external terminology schemas is given in the Scope. This clause provides a synopsis of the coordinated set of Recommendations/standards for the management of telecommunication services and resources. Formalization of interconnection designations among operators networks ITU-T M.1401 This Rec
38、ommendation contains data definitions for designations of interconnections and other information about network resources that are required to be communicated between operators. The focus is on design of object identifiers, their name spaces and name bindings. The Recommendation provides a data struc
39、ture for the management of logical network resources. The objects of communication are network interconnection points (places, stations, nodes, etc.), interconnection links, terminating and originating connections, and transit connections. Correct terms for these are provided by the application sche
40、ma defined in this Recommendation. Formalization of orders for interconnections among operators networks ITU-T M.1404 This Recommendation extends ITU-T M.1401 and ensures the use of ITU-T M.1401 in orders containing designations of interconnections among operators networks. Any statement that can be
41、 made according to ITU-T M.1401 can be made within a Message of an Order. Data definitions for inventory management according to ITU-T M.1401 are reused for order management according to this Recommendation. Hence, the data design is made to fit both domains. A mapping between the two domains is pro
42、vided. This mapping allows recording of all statements about a particular resource. Formalization of designations for service management among operators ITU-T M.1402 This Recommendation defines data for products, customers, accounts, contracts, deals, addresses, prices, and various segments and rela
43、tionships among all of these. The focus is on design of object identifiers, their name spaces and name bindings. Also, care is taken to design lists that provide easy overview of data by the end users, since conceptual designs are not sufficient. This Recommendation reuses data in product catalogues
44、 as schemata for product instances within the customer database. These product instances are again reused as schemata for service usage. Reuse over several application domains is accomplished through use of recursion. Hence, the data definitions span many application domains, such as product catalog
45、ues, customer relationship management, order management, rating and service platforms. However, the Recommendation does not claim to be complete in any of these domains. Particular emphasis has been made to simplify the data structure and functions of the service platform. Formalization of designati
46、ons of orders for service management among operators ITU-T M.1405 This Recommendation extends ITU-T M.1402 and ensures the use of ITU-T M.1402 in orders containing service management information. Any statement that can be made according to ITU-T M.1402 can be made within a Message of an Order. Data
47、definitions for service management according to ITU-T M.1402 are reused for order management according to this Recommendation. Hence, the data design is made to fit both domains. A mapping between the two domains is provided. This mapping allows recording of all statements about a particular object.
48、 ITU-T M.1405 is a twin to ITU-T M.1404. Customer requests and orders according to ITU-T M.1405 may be expanded to become network orders according to ITU-T M.1404. The application designers should take great care to choose whether message-based communication by orders or object-based communication b
49、y ITU-T M.1401 or ITU-T M.1402 should be used over a particular interface. 4 M series Supplement 7 (05/2008) Formalization of generic orders among operators ITU-T M.1403 This Recommendation defines orders and messages within orders. The orders may contain data for designations of interconnections and other information about services and network resources that are required to be communicated between operators. Generation of derived orders is described, and reuse of message
