ITU-T M.1400 PDF

This Recommendation defines designations and additional information intended primarily for human-to-human communication between various operators, i.e., network operators or service providers.

This Recommendation focuses on human needs for stable and recognizable data formats independent of the media through which they are communicated. Therefore, in order to support the human-to-human communication, the formats defined in this Recommendation will have to be provided at the corresponding human-to-computer interfaces as well. Hence, this Recommendation defines the presentation formats of data at human-to-computer interfaces, but does not define the data communication formats for interfaces between computer systems such as at the telecommunications management network (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.

This Recommendation extends the previous designation of international routes to also cover routes between national operators. However, use of this Recommendation inside national jurisdictions would be subject to national regulation and/or bilateral agreement between operators. Although compliance with all ITU-T Recommendations is voluntary, special mention is made for Recommendation ITU-T M.1400 due to the sensitivity of designations for interconnection from 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 both designations and additional information to be exchanged between two operators. However, this Recommendation focuses on information on network resources, operators and their addresses, and does not define order or transaction identification or additional information on the status or processing of these orders or transactions.

The definition of information is independent of which function it supports. However, the selection of information defined in this Recommendation basically supports provisioning and network maintenance. In addition, this Recommendation may cover some information required for other TMNs or non-TMN functions, such as ordering and billing.

This Recommendation aims at supporting communication between network operators, but may also support communication among 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 supporting the network, and serves as design information for developers of operational support systems.

This Recommendation is presented in informal usual language, tables and figures. To support automatic interaction between computer systems of various operators, more formalization is needed. Also, the formalization may lead to redefinition of the scope of this Recommendation. These issues are for further study.
