scope:

This Recommendation provides a cooperation model that can promote optimal cable utilization across multiple countries and boost regional and international connectivity. The model is based on proportional allocation method, which allocates end-to-end circuit capacity based on the length of fibre contributed to the trans-multi-country terrestrial cable network.

Throughout this Recommendation, the terms ''cable'' or ''trans-multi-country terrestrial cable network'' refer to existing terrestrial fibre cables already deployed.

The scope of this Recommendation is limited to the physical terrestrial cable network, i.e., the transport network. The various and more complicated factors that impact the charging and costs of the Internet, i.e., the Internet Protocol (IP) network, are not discussed herein. Recommendation ITU-T D.50 [b-ITU-T D.50] and its associated Supplements should be consulted for the provisions of IP-based international Internet connections.
