This Recommendation defines orders and additional information intended primarily for human-to-human communication between various Operators, i.e., network operators or service providers. The orders contain data for designations of interconnections and other information about services and network resources that are required to be communicated between operators. This Recommendation provides a skeleton that can be extended with any contents and allow for any use of the orders. This Recommendation is developed in order to facilitate computerized interoperation between telecommunication operators. As the data defined in this Recommendation are designed for human usage, they are independent of the functions in which they are used. Hence, the data may be applied in any functions, e.g. in customer requests, call centers, billing, service platforms etc.
