Summary:
|
Scope: The study aims to identify charging and accounting settlement challenges pertaining to trans-multi-country transmission circuit, especially excessive transit costs. Relevant difficulties will be analysed and options identified which could facilitate the utilization of spare domestic terrestrial cables to carry international trans-border traffic. It will also study how the combination of terrestrial and submarine cables will improve international connectivity around the globe as per case studies and solutions.
Summary: Currently, in the absence of a set of international guidelines which addresses the transmission circuit charges on trans-multi-country terrestrial cables, the existing terrestrial cable resources are effectively utilized only between two neighbouring countries. Once a third or more countries are involved, these resources will lie under-used due to over- charging by the intermediate countries for the transmission circuit services. The overcharging on transit is also the reason why landlocked countries have great difficulty in connecting to submarine cables. As large quantities of spare domestic terrestrial cables fail to be utilized in carrying the traffic of international trans-border service, it is a waste of all these network resources. Besides, submarine cables cannot benefit from the international internet traffic flow generated by improved terrestrial interconnectivity.
This study will cover identification of overcharge issues pertaining to trans-multi-country terrestrial transmission circuit and demands of all concerned parties, especially land-locked countries' access to submarine cables. Appropriate solutions will be provided using the basic principle of allocating designed end to end trans-multi-country circuit channels according to the proportion of length of fibers contributed for the international transmission network from each party.
