Summary

Based on the framework set forth in ITU-T Rec. Y.140, this Recommendation concentrates on one of the interconnection scenarios relevant to GII, the interconnection between operators of public telecommunication networks (PTNOs) and service providers (SPs). After looking at the situation before and during transition to a full implementation of the so-called enterprise model, attributes of reference points for interconnection between PTNOs and SPs are dealt with in some detail. Separate clauses treat the various aspects of these attributes, in particular, security, service interaction, charging/billing, service availability, access to a network address and management. The content of this Recommendation should be seen as a guideline for consideration by involved parties when implementing the GII concept within a Next Generation Network.
