[ITU-T J.700] describes the service requirements and functional framework architecture for the support of broadcasting services enhanced by IP technology over secondary distribution (e.g., cable and optical, etc.) networks. It addresses the service requirements, use cases and functional components required to support these requirements. Where possible, [ITU-T J.700] utilizes material already developed or under development in ITU-T Recommendations that are related to video service delivery over secondary networks.

The scope of this Recommendation is the i-2 interface, identified in [ITU-T J.700] and in Figure 1, that enables the service client in the customer network to interface with the operations support systems (OSS) functions in the operator network to provision and manage the IPTV client functions in the customer network. Examples of OSS functions include client provisioning, activation, configuration, and management (PACM).
