scope:

This Recommendation contains the requirements for service and product lifecycle management across business to business interfaces in support of NGNs. In general, the lifecycle of services and products includes development, negotiation and sales, implementation, execution, assessment, and decommission phases (See [ITU-T M.3050.3]). In this Recommendation, the interface focuses only on the interactions between a service provider and its suppliers and partners. In each phase, the exchange of service and product information is required between the service provider and its suppliers and partners across business to business (B2B) interfaces. This Recommendation focuses on the requirements of B2B interfaces which cover all of these phases. The requirements are provided using the TMN interface specification methodology described in [ITU-T M.3020].
