9、ternational Telecommunication Union (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,

10、 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 study groups which, in tu

11、rn, 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 basis with ISO and IEC. NOT

12、E In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e

13、.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The 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 s

14、uggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the e

15、vidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, whic

16、h may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

M.1404 (08/2007) Introduction This Recommen

18、dation defines order designations and additional information intended primarily for human-to-human communication between various operators, e.g., network operators, within the context of an external terminology schema in end-user terminology. The area of interest is the communication of orders betwe

19、en operators about network interconnections and network services. These orders may also be relevant for network planning and installation companies and other entities. The objects of communication are network interconnection points, places, stations, nodes, etc., interconnection links, and terminati

20、ng and originating connections and transit connections. These terms are defined in ITU-T M.1400 and ITU-T M.1401. This Recommendation focuses on human needs for stable and recognizable data formats independently of the media they are communicated over. Therefore, in order to support the human-to-hum

21、an 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 formats of data at human-to-computer interfaces, but does not define the data communication formats for interface

22、s between computer systems, such as at the TMN X interface or non-TMN computer interfaces. However, it must be possible to automatically map the human-to-computer formats to the computer-to-computer formats and vice versa. The details of this mapping are for further study. Use of this Recommendation

23、 inside national jurisdictions will be the result of bilateral negotiation between the operators and/or national regulatory activity. Although compliance with all ITU-T Recommendations is voluntary, special mention is made for ITU-T M.1404 due to the sensitivity of designations for interconnection f

24、rom a regulatory and legal standpoint. This extension greatly increases the number of routes and nodes to be identified, and in this way extends the name spaces to be provided. This Recommendation defines orders and additional information to be exchanged between two operators. While it defines order

25、 and message identification, it does not define data on the status or processing of these orders or messages. In this regard, this Recommendation can be considered as an adaptation or extension of ICT industry standards, e.g., OASIS UBL. ICT industry standards for such data may impose additional req

26、uirements on human-to-computer interfaces. 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. This Recommendation aims at supporting communication between

27、 network operators, but may also support communication between network operators and service providers, brokers, retailers, customers and installation providers. This Recommendation aims at defining designations and additional information for technicians and file support personnel at their terminals

28、 supporting the network, and serves as design information for developers of operational support systems. ITU-T Rec. M.1404 (08/2007) 1 ITU-T Recommendation M.1404 Formalization of orders for interconnections among operators networks 1 Scope The area of interest is the communication of orders between

29、 operators about network interconnections. The objects of communication are network interconnection points, places, stations, nodes, etc., interconnection links, and terminating and originating connections and transit connections. These terms are defined in ITU-T M.1400 and ITU-T M.1401. The focus o

30、f this Recommendation is on end-user terminology, as defined in an external terminology schema, which puts requirements on other schemata and implementations. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute pr

31、ovisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommenda

32、tions and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published.
