17、s to be applied in their telephone relations, it is recommended that they take into consideration: - for the determination of accounting rate shares and accounting rates, the provisions of clause 2 (Determination of accounting rate) of this Recommendation and the provisions of Recommen- dation D.307

18、 R; for fixing tariffs for frontier relations, the provisions contained in clause 4 of this Recommendation. - 11 Recommendation D.300 R (03/95) Recommendation D.300 R DETERMINATION OF ACCOUNTING RATE SHARES IN TELEPHONE RELATIONS BETWEEN COUNTRIES IN EUROPE AND THE MEDITERRANEAN BASIN11 2) 3) (revis

Explanation of some of the term used in this Recommendation 2 Determination of accounting rate share in telephone relations between countries in Europe and the Mediterran

20、ean Basin 2.1 General 2.1.1 Since the setting-up of any international call involves both the international network and the national networks of the terminal countries, the accounting rate share due to each country is derived from three basic elements, to which separate standard rates are applied: th

21、e line (transmission) part of the international network, which includes the various transmission systems used and is a function of the distance; the international exchange, i.e. the switching part of the international circuit, plus the terminal transmission equipment; the national extension, which c

22、overs the cost of the national exchanges and trunk transmission means for the delivery of international calls. Noting the definition of national extension in Recommendation D.OOO the TEUREM Group did not include the local loop in its cost analysis. - - - 2.1.2 In special cases where the line (transm

23、ission) part of an international connection is: - - a HF radio link, a tropospheric scatter link; or the provisions of this Recommendation with regard to the determination of an accounting rate share in relation to the length of the international circuit are not applicable, and accounting rate share

24、s should be agreed upon between the Administrations concerned. Cases in which the line (transmission) part of a connection is a satellite link are dealt with in Annex B. 2.2 Charging zones For calculating accounting rate shares, each country may be divided into charging zones. If need be, different

25、charging zones may be fixed in a given country for traffic exchanged with different countries. It is desirable that the number of charging zones for international traffic, in any one country, should be reduced to a minimum. As a general rule, in services between non-adjacent countries, each country

26、should constitute one single zone. ) Countries in the Mediterranean Basin are countries not belonging to Europe but bordering the Mediterranean Sea. 2, Since the TEUREM cost analysis covered only some of the countries of the Region, the standard rates given in this Recommendation are to be considere

27、d as indicative only. 3, The standard rates given in this Recommendation are expressed in the monetary unit of the International Monetary Fund (IMF), the special drawing right (SDR). In accordance with the international Telecommunication Regulations, the gold franc is equivalent to U3.061 SDR. Recom

28、mendation D.300 R (03195) 1 ITU-T RECMN*D.300R 95 4862593 Ob00848 573 2.3 2.3.1 Calculation of distances (line part) Distances to be taken into consideration 2.3.1.1 General case 2.3.1.1.1 In determining the share payable to a country for the use of international circuits, the distance to be taken i

29、nto consideration is: In a terminal country - The crowflight distance between: a) b) the point at which the international circuit crosses the frontier; and the international exchange at which the circuit terminates. In a transit country - The crowfight distance between the two frontier points at whi

30、ch the international circuit enters and leaves the country in question. 2.3.1.1.2 The same provisions apply to the determination of crowflight distances for groups, supergroups, mastergroups and supermastergroups. The above provisions for the calculation of distances apply to international circuits

31、both on land cables and on radio- relay links. 2.3.1.2 Special cases 2.3.1.2.1 Radio-relay links crossing the sea or a third country When a frontier is crossed by a radio-relay section of an international circuit passing over a third country or over the sea, without an intermediate relay station, th

32、e frontier point for measuring the circuit length shall be the point midway between the two relay stations on either side of the frontier. 2.3.1.2.2 Submarine cables With regard to international circuits which are routed in submarine cables, the distance to be used for accounting will be calculated

33、as follows: a) for the land section of the circuit to the submarine cable station, the distance shall be calculated in accordance with the general principles (Le. the crowflight distance), it being assumed that the point at which the circuit crosses the frontier is the cable station; b) for the subm

34、arine cable section, the distance used shall be the actual route distance between the submarine cable stations as determined and agreed by the joint owners of the cable; the distance will be divided appropriately (normally 50/50) between the countries at the extremities of the cable. 2.3.1.2.3 Speci

35、al itineraries In exceptional circumstances, multiplication factors may be applied to the crowflight distance, from which the terminal and transit shares are calculated, to take account of special itineraries. For example, in the case of a direct transit country, the crowflight distance between the

36、points on the frontier at which the circuit enters and leaves the country may (in exceptional circumstances) be replaced by a length representing the sum of two crowflight segments making up a broken line, etc. 2.3.2 Possibility of weighting distances For calculation of the crowflight distances for

37、the international section, a weighting according to the number of circuits is normally applied in a given relation to simplify accounting: - when there are several international arteries with different itineraries terminating at an international exchange: when there are several international exchang

38、es in a country for the relation concerned. - 2 Recommendation D.300 R (03/95) - ITU-T RECMN*D.300R 95 U 48b259L Ob00849 408 This weighting serves to determine a length (crowflight distance) for fixing the accounting rate share relating to the intemational section and it would remain in force as lon

39、g as the structure of the network was not significantly changed. This length of the international section would then be used to fix the international section element for the charges for international telephone and telegraph circuits, groups, supergroups, mastergroups and supermastergroups. 2.3.3 Rou

40、nding off distances 2.3.3.1 Distances less than 50 km shall be rounded up to 50 km. Example: distance of 24 km rounded up to 50 km. Other distances shall be rounded to the nearest multiple of 50 km. Examples - - - 2.3.3.3 This rounding rule applies to the distances in each of the terminal countries

41、and in each of the transit countries and is applied to the total distance calculated for any one country. It is applicable to the remuneration of Administrations both on the basis of a flat-rate price for the facilities made available and on the basis of traffic units. 2.3.3.4 When distances are wei

42、ghted in accordance with the provisions of 2.3.2 above, the rounding shall be applied only after the weighted distance has been calculated. 2.3.4 When in a given relation there are several routes traversing different countries, these transit countries shall in ali cases receive the share or flat-rat

43、e price normally due to them for the distance between the points of entry and exit; any cost of equalizing collection charges in a relation comprising different routes shall be borne solely by the Administration of the country of origin and no deduction shall be made from the remuneration due to the

44、 transit countries. 2.3.3.2 distance of 72 km rounded to 50 km; distance of 126 km rounded to 150 km; distance of 175 km rounded to 200 km. Existence of several routes in a given relation 2.4 For international accounting purposes, there are two methods of remuneration for the facilities made availab

46、diterranean Basin, standard per-minute rates have been calculated for automatic traffic, taking into account the results of the former Recommendation D.300 R (Red Book) referring to only analogue system and from digital cost analyses carried out in 1990. 2.4.1.2 Since the degree of digitization vari

47、es from country to country and over time, the method of determining accounting rate shares in this Recommendation uses a simplified division into categories to better reflect differences in cost structures among Administrations. on the basis of traffic units; on the basis of a flat-rate price for th

48、e facilities made available. 4, Use of charged time for international accounting instead of conversation According to their equipment, some Administrations may have to use charged time data for international accounts instead of conversation time, the charged time being given, for example, by the ope

49、rators ticket. In such a case, the Administration of origin will consult the Administration of destination and, when necessary, the Administration of transit countries, to see whether it is necessary to adjust the number of minutes entered in the international accounts to make allowance for the small difference which may exist between the charged time they use and the conversation time they should use for accounting according to Recommendation D. 150 and this Recommendation.
