4、lecommunication Union (ITU). CCIT 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 CCIT which meets every four years, establishes the topics for stud
5、y 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 CCIT Resolution No. 2 (Melbourne, 1988). Recommendation D.10 was prepared by Study Group III and was approved under
6、the Resolution No. 2 procedure on the 15th of July 1991.

8、RVICES (revised 1991) Preamble This Recommendation sets out the general principles and conditions applicable by Administrations to data communication services over international public networks dedicated to this type of communication. It is recognized that this is a rapidly developing field at the p
9、resent time in terms of the diversity of application and flexibility is therefore essential. The tariff principles contained in this Recommendation do not apply to leased circuits for private use (see Recommendation D. 1). 1 General 1.1 Administration by means of a public data network dedicated to t
10、his type of communication. A public data communication service is a data communication service established and operated by an 2 Charging 2.1 General principles 2.1.1 Tariffs developed for public data communication service should: - - - - - - - take into account the provisions of Recommendation D.5;
11、take into account tariff relationships with other services provided by the Administrations; be flexible enough to enable new needs to be accommodated as the service develops; be as administratively simple as possible; take into account the geographical configuration of countries; not impart undue ad
12、vantage or disadvantage to any category of user; encourage customer choice depending upon his needs as to the use of circuit or packet-switched services where the alternative exists; be such as to encourage the use of public data network, meet the needs of as many users as possible, and promote opti
13、mum growth and utilization of the network; be easily understood by subscribers; - - - 2.1.2 Each Administration shall, subject to the applicable national law, establish the charges to be collected from its customers. The level of the charges is a national matter; however, in establishing these charg
14、es, Administrations should try to avoid too great a dissymmetry between the charges applicable in each direction of the same relation. sustain the service on a long-term basis. 2.2 Tariff components 2.2.1 utilization component. The tariff should normally consist of two components: the network access
15、 component and the network Recommendation D.10 1 CCITT RECNN*D.LO 33 4862573 05b0.523 7 2.2.2 represents the cost of the service which is not dependent on network utilization. The network access component, normally intended to cover the cost of making the service available, 2.2.3 2.2.4 The network u
16、tilization component normally covers the costs which are dependent on network utilization. Some factors which may be taken into account in developing tariffs include, for example: - - - type of switching; - - distance; - - route; - other functions. user class of service (see Recommendation X. 1 i);
17、optional user facilities (see Recommendation X.2 2); volume of data and/or duration of call; time (peak and off-peak periods); While certain of the above factors may be more closely associated with one component or another, some may be associated with both. The particular application of some factors
18、 will depend on the type of switching employed. 3 Accounting 3.1 Administrations should, by agreement, establish the overall accounting rate applicable in a given relation and divide that rate into terminal shares payable to the Administrations of the terminal countries and, where appropriate, into
19、transit shares payable to the transit Administration(s). The same accounting rate should apply in both directions of a given relation. The overall accounting rate between two terminal countries should be the same irrespective of the route used. 3.2 Normally only the network utilization component sho
20、uld be considered for international accounts. 3.3 The gathering of information required for charging and accounting should normally be the responsibility of the calling Administration. Additionally, if the interconnection of dissimilar networks occurs at the called Administration, then the latter sh
21、ould be responsible for providing the calling Administration with the necessary data for charging and accounting. 4 interworking of public data communication services 4.1 Normally, the interconnection of dissimilar data networks (such as packet-to-circuit) should take place at the originating or ter
22、minating country Administration. However, conversion at a transit point may be provided if the originating, terminating and transit country Administrations agree. 4.2 alternatives which provide for the use of data circuits between international data communication centres (gateways). 4.3 avoided. In
23、the cases where intenvorking is permitted, it is recommended that preference be given to the intenvorking Interconnection of a public data network with a public telephone/telex network in a transit country should be 4.4 Tariff principles in the case of interworking between dissimilar data networks s
24、hall be as follows: 4.4.1 Collection charges 4.4.1.1 The charge shall be, according to the policy of the origin Administration, either: a) b) the international charge applicable to the originating network, or the charge for the international network used. 2 Recommendation D.10 CCITT RECMN*D-LO 91 =

Note - The desirability and po
26、ssibility of adjusting the accounting rates to include the cost of providing interworking facilities used for international data traffic needs further study in consultation with Study Group I and other relevant Study Groups.
