9、ciple in transit relations Summary The Tariff Group for Africa recommends that Administrations in Africa negotiate and apply the principle of “sender pays transit“ for all transit relations, the destination share being that of the direct relation. Source ITU-T Recommendation D.602 R was prepared by
10、ITU-T Study Group 3 (2001-2004) and approved under the WTSA Resolution 1 procedure on 13 December 2002. ii ITU-T Rec. D.602 R (12/2002) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Stan
11、dardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), w
12、hich meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within
13、 ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS IT
14、U draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU memb
15、ers or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may no
16、t represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2003 All rights reserved.

17、on D.602 R Application of the “sender pays transit“ principle in transit relations The Tariff Group for Africa, recognizing that overflow constitutes a solution for routing traffic when direct circuits are saturated, noting a) that some operators abuse the system by diverting large volumes of traffi
18、c via overflow routes; b) the fall in income from net settlement balances due to payment of the transit share for overflow traffic; c) the practice of confidential transit rates in one direction of relations between two operators; d) the existence of the least cost-routing mechanism, recommends that
19、 Administrations negotiate and apply the principle of “sender pays transit“ for all transit relations, the destination share being that of the direct relation.
