INTERNATIONAL TELECOMMUNICATION UNION ITU-T RECOMMENDATION SUMMARY Rec. No. : D.73 Title : General tariff and international accounting principles for interworking between the international bureaufax and telefax services Study Group : III - Tariff and Accounting Principles Version : Revised Date of adoption : 1992 Notes : Recommendation D.73 sets out the charging and international accounting principles applicable by Administrations for the transmission of facsimile documents in both directions between subscribers to the telefax service and public facsimile bureaux. In determining the tariff principles to be applied to this service, consideration should be given to the structure and level of charges applicable to other international telecommunication services supplied by the Administrations concerned, and to the provisions of Recommendation D.5. Charging principles The originating Administration should charge either on a per page basis or on the normal call charge for the international network used. International accounting principles Generally speaking, accounting procedures for interworking between the international bureaufax and telefax services should be based on the same accounting rates and be effected in the same manner as for the calls set up normally on the international public network used. These facsimile calls are an integral part of the international accounts for the public network and should not give rise to any additional accounting measures between Administrations. Recommendation D.73 also sets out the principles applicable to refunds and to service correspondence.
