4、mittee) is a permanent organ of the International Telecommunication Union (ITU). CCITT 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 Plenary Assembly of CCITT which m
5、eets every four years, establishes the topics for study and approves Recommendations prepared by its Study Groups. The approval of Recommendations by the members of CCIT between Plenary Assemblies is covered by the procedure laid down in CCITT Resolution No. 2 (Melbourne, 1988). Recommendation D.60
6、was prepared by Study Group III and was approved under the Resolution No. 2 procedure on the 15th of July 1991. CCIT NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication Administration and a recognized private operating agency. O I

8、PLES TO GOVERN THE APPORTIONMENT OF ACCOUNTING RATES IN INTERCONTINENTAL TELEX RELATIONS (Geneva, 1980, revised 1991) The CCITT, considering (a) that the accounting rates applicable to telex traffic in various regions are already established in certain CCITT Recommendations; (b) that neither Recomme
9、ndation D.67 nor any other Recommendation contains provisions determining the sharing of accounting rates to be applied to intercontinental telex traffic; (c) that it would be desirable to establish certain guiding principles to govern the apportionment of accounting rates in intercontinental telex
10、relations; (d) that, for reasons of equity, it would be desirable for the accounting rate to be shared by the participating Administrations (terminal or possibly transit) in proportions which take account of the service provided by each of these Administrations; recommends General principles In an i
11、ntercontinental telex relation, the bilateral or multilateral agreement behveen the Administrations concerned should normally establish the same accounting rate for both directions of the relation regardless of the route utilized. 1 Direct relations 1.1 is, over circuits provided for the exclusive u
12、se of the terminal Administrations. A direct relation is one between two terminal Administrations where traffic is routed over direct circuits, that 1.2 For the routing of traffic over direct circuits, the accounting rate is in principle divided between the Administrations of the terminai countries
13、on a 50/50 basis for both directions of traffic. Proportions other than 50/50 may be used when the intercontinental facilities made available by each of the Administrations of the terminai countries are not approximately equivalent. 1.3 deuiment of the country of destination: In cases where a direct
14、 relation exists and traffic is diverted by the Administration of origin to the financial - unilaterally, via an unauthorized transit route, or - unnecessarily (Le. for other than genuine overflow traffic reasons or to meet routing difficulties), via an authorized overflow transit route, it is for t
15、he Administration of origin to reach agreement with the transit Administration and to remunerate it from the amount of the country of origins terminal share, unless the Administration of destination is prepared to agree to a different share. The above does not apply when the Administration of destin
16、ation does not implement the number of channels required by the Administration of origin in order to provide for a grade of service in which the loss probability in the busy hour will not be more than 1 call in 50. Recommendation D.60 1 CCITT RECNN*D.bO 91 LIBb259L 0560549 3 9 1.4 If a relation is t
17、he subject of a bilateral agreement for the routing of traffic flow on a direct circuit and consistentiy gives rise to traffic flow difficulties or genuine overflow traffic necessitating recourse to a transit routing in one or both directions, the sharing of the overall accounting rate may be the su
18、bject of agreement, for the traffic routed in transit as provided in 0 2.2 below. 2 Transit relation) 2.1 A transit relation is a relation between two terminal Administrations where traffic is routed by switching in an international transit exchange(s) located in a country or countries other than th
19、e country of origin or the country of destination, 2.2 In a transit relation, the accounting rate should normally be divided into two terminal shares and one or more transit shares depending upon the circumstances. In negotiations concerning the division of the accounting rate it is recommended that
20、 the balance of the accounting rate, after deduction of the transit shares, be divided equitably between the terminal Administrations concerned. For example, a division of 50/50 may be used when the facilities provided by the terminal Administrations are approximately equivalent. Proportions other t
21、han 50/50 may be used when the facilities made available by each of the Administrations of the terminal countries are not approximately equivalent, or where a 50/50 division would not otherwise be equitable. 1 Canada, China and the United States of America have expressed reservations regarding the application of the provisions of $2. 2 Recommendation D.60
