The Applicants and their affiliates will operate the Amitié system on a non-common-carrier basis, either by providing bulk capacity to wholesale and enterprise customers on particularized terms and conditions pursuant to individualized negotiations or by using the Amitié cable system to serve their own internal business connectivity needs. The existence of robust competition on U.S.-U.K., U.S.-France, and (more broadly) U.S.-Western Europe routes obviates any need for common-carrier regulation of the system on public-interest grounds.

  • Interim Report on the Asian Telecom Connectivity Market
    Asian Telecom Connectivity Market: Executive Summary (Research conducted 2005) The following is a summary of the findings of the Telecommunications Research Project University of Hong Kong NOTE1 The original research was undertaken for a private client in 2005 and the detailed report and recommendations are therefore not publicly available, but the following Executive Summary was made available at the time to companies who provided information and their opinions. In respect of demand and supply, the research goes beyond the data and analysis provided by TeleGeography (an industry benchmark publication) by estimating various rates of growth of demand against estimates of capacity lit and capacity used, thereby projecting various dates of capacity exhaustion. Unity Cable Since this research the 10,000 km Unity Cable connecting Japan and the USA has been announced (2008) consisting of carriers SingTel, Bharti- Airtel and KDDI, together with Internet companies Google, Pacnet and Global Transit (subsidiary of Malaysian network exchange company, AIMS). 1 This Executive Summary also appears as Appendix 2 in John Ure (ed.) Telecommunications Development in Asia, HKU Press, April 2008 1 Asian Telecom Connectivity Market: Executive Summary2 Between June and August 2005, the Telecommunications Research Project (TRP) at the University of Hong Kong undertook an extensive look at the regional bandwidth market. The research study was undertaken with intent to understand both the supply (and pricing) and demand sides of the equation, based upon feedback direct from carriers and experts, on the one hand, and from those directly purchasing bandwidth on the other. It quickly became apparent that the supply and demand of bandwidth represent two distinct stories which, not only are not necessarily in alignment (obvious enough to anyone who has been watching the market over the last 10 years), but are at times quite seriously disconnected in their fundamental drivers.
