6、fines designations and additional information intended primarily for human-to-human communication between various Operators, i.e., network operators or service providers. This Recommendation contains data definitions for designations of interconnections and other information about network resources
7、that are required to be communicated between operators. This Recommendation is developed in order to facilitate computerized interoperation between telecommunication operators. For this use a more formal approach than M.1400 is required. See Appendix III. Note that since ITU-T Rec. M.1400 does not f
8、ormally specify data structures, backward compatibility with existing implementations may not be ensured, but this Recommendation is based on ITU-T Rec. M.1400. For further details, see Appendix II. Source ITU-T Recommendation M.1401 was approved on 14 July 2006 by ITU-T Study Group 4 (2005-2008) un
9、der the ITU-T Recommendation A.8 procedure. Keywords Data definitions, designations, domestic, interconnection, international, operator, terminology, X interface. ii ITU-T Rec. M.1401 (07/2006) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the f
10、ield of telecommunications. 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 issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The
11、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 topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
12、 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 Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a re
13、cognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The
14、words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility t
15、hat the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommend
16、ation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and
17、 are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr. ITU 2006 All rights reserved.

M.1401 (07/2006) Introduction This Recommendation defines designations and additional information intended primarily for human-to-human
21、communication between various Operators, i.e., network operators or service providers. The area of interest is the communication between operators about network interconnections and network services. The objects of communication are network interconnection points, places, stations, nodes, interconne
22、ction links, and terminating and originating connections and transit connections, etc. Correct terms for these are provided by the application schema defined in this Recommendation. This Recommendation focuses on human needs for stable and recognizable data formats independently of what media they a
23、re communicated over. Therefore, in order to support the human-to-human communication, the formats defined in this Recommendation are required to be provided at the corresponding human-to-computer interfaces, as well. Hence, this Recommendation defines the presentation formats of data at human-to-co
24、mputer interfaces, but does not define the data communication formats for interfaces between computer systems, such as at the TMN X interface or non-TMN computer interfaces. However, it should be possible in the future to automatically map the human-to-computer formats to the computer-to-computer fo
25、rmats and vice versa. The details of this mapping are for further study. Use of this Recommendation within national jurisdictions may be imposed by the national regulator or may be the result of bilateral negotiation between the operators and/or national regulatory authorities, in accordance with na
26、tional laws and regulations. The Recommendation defines both designations and additional information to be exchanged between two Operators. However, this Recommendation focuses on information on Operators, network resources and their addresses, and does not define order or transaction identification
27、 or additional information on the status or processing of these orders or transactions. The definition of information is common for the functions it supports. However, the selection of information defined in this Recommendation basically supports provisioning and network maintenance. In addition, th
28、is Recommendation may cover some information required for other TMN or non-TMN functions, such as ordering and billing. This Recommendation aims at supporting communication between network operators, but may also support communication between network operators and service providers, brokers, retaile
29、rs, customers and installation providers. This Recommendation aims at defining designations and additional information for technicians and file support personnel at their terminals supporting the network, and serves as design information for developers of operational support systems. This revision t
30、o ITU-T Rec. M.1401 (05/2005) replaces every occurrence of Town with Geographical Area on the basis of Geographical Area being more applicable for the termination of routes than Town. In addition, this revision aligns ITU-T Rec. M.1401 more closely with the ATIS Standard for location identification,
31、 which is not restricted to a town. Also, text for several data items is repositioned in keeping with the alphabetical sequence of attribute groups and attributes as stated in Clause 5, Conventions. ITU-T Rec.

M.1401 (07/2006) 5 Conventions Figure 1 shows boxes containing object class labels to indicate ob
39、ject classes. Lines supported with a reversed arrowhead indicate subordinate object classes. Lines with two-way arrows indicate references between object classes. A dashed one-way arrow with an S at the arrowhead indicates a schema reference and is here used for stating recursion. The text that foll
40、ows Figure 1 includes a label and explanation for each class in the schema. A class can be an object class, an attribute class, or a reference class. The level of each class is depicted in the text by indentations (5 mm) of the class label, supported with dashes, where the number of indentations and
41、 dashes indicates the level of a given class within the schema. Therefore, each class label has a given indentation based on the Figure 1 schema graph. Labels of data items that are subordinate to or referenced from a given object class are presented in the following sequence: 1) alphabetized object
42、 class attributes; 2) alphabetized object class references; and 3) alphabetized object classes that are contained within the given object class at the next lower level. Textual definitions and explanations of object classes, attributes and references are provided in paragraphs that are adjusted 5 mm
43、 further to the right of their respective labels. Object class labels are underlined; attribute group and attribute labels are not underlined. Object class references are written in blue, italics and underlined. The formalism used in this Recommendation is introduced in Appendix III. Data attributes
44、 other than Local identifiers consist of sequences of characters taken from Table 1/T.50, each character being either alphabetic (A-Z) or numeric (0-9). Local identifiers consist of sequences of characters which may include characters from other character sets (for example, the non-Latin characters
45、in ITU-T Rec. T.52), on the basis of appropriate bilateral and/or multilateral agreements. Additional requirements for symbols are explicitly stated in format requirements for specific attributes. It is recommended that alphabetic characters be represented with upper-case letters unless stated other
