INTERNATIONAL TELECOMMUNICATION UNION ITU-T TELECOMMUNICATION STANDARDIZATION SECTOR OF ITU D.210 (09/94) CHARGING AND ACCOUNTING IN INTERNATIONAL TELECOMMUNICATION SERVICES GENERAL CHARGING AND ACCOUNTING PRINCIPLES FOR INTERNATIONAL TELECOMMUNICATION SERVICES PROVIDED OVER THE INTEGRATED SERVICES DIGITAL NETWORK (ISDN) ITU-T Recommendation D.210 (Previously “CCITT Recommendation”) FOREWORD The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The 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 Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993). ITU-T Recommendation D.210 was revised by ITU-T Study Group 3 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 15 th of September 1994. ___________________ NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. © ITU 1995 All rights reserved.

CONTENTS Recommendation D.210 (09/94) Page 1 General principles........................................................................................................................................... 1 2 Collection charges .......................................................................................................................................... 1 3 Accounting ..................................................................................................................................................... 2 Annex A – Summary description of bearer services, teleservices and supplementary services ............................... 3 Recommendation D.210 (09/94) i PREAMBLE This Recommendation sets out the general principles for charging and accounting to be applied by Administrations for the provision of international telecommunication services over an Integrated Services Digital Network (ISDN). These services are defined in the relevant ITU-T Recommendations. Charging and accounting principles for interworking between services provided over the ISDN and services provided over other networks are contained in other Recommendations in the Series D.200. ii Recommendation D.210 (09/94) Recommendation D.210 Recommendation D.210 (09/94) GENERAL CHARGING AND ACCOUNTING PRINCIPLES FOR INTERNATIONAL TELECOMMUNICATION SERVICES PROVIDED OVER THE INTEGRATED SERVICES DIGITAL NETWORK (ISDN) (Melbourne, 1988, revised in 1994) The ITU-T, considering (a) that an Integrated Services Digital Network (ISDN) provides digital connections between user-network interfaces, enabling Administrations to offer integrated access to a wide range of international services in association with a multi-service signalling system; (b) that it is desirable to achieve as far as practicable the harmonization of charging and accounting principles for the international services to be provided over the ISDN; (c) that charging and accounting principles and structures for the ISDN should be flexible enough to accommodate the variety of ISDN implementation and regulatory approaches that apply in different countries; (d) that it is desirable to adopt charging and accounting structures, which are as simple and easy to understand as is practicable with the wide range of services envisaged; (e) that the installation of the ISDN in various countries will in all probability take place in several stages known as the “transition phase” during which ISDN and other networks will coexist and interwork, and that during this phase due account should be taken of charging and accounting structures and levels for services provided over other networks, recommends 1 General principles The charging and accounting principles applicable to the services to be provided over the ISDN should: a) take into account the provisions of existing D-Series and other pertinent ITU-T Recommendations; b) take into account the different categories of service as defined in Recommendations I.230, I.240 and I.250 (see Annex A); c) take into account the network resources and the functions required for the provis
