14、f some of the terms used in this Recommendation An explanation of some of the terms used in this Recommendation is given in Recommendation D.000. 2 Determination of accounting rate shares in telex relations between countries in Africa 2.1 General 2.1.1 Since the setting up of any international call

15、involves both the international network and the national networks of the terminal countries, the accounting rate share for each country is derived from three basic elements, to which separate standard rates are applied: the fine (rransmission) part of the international network, which includes the va

16、rious transmission systems used and is based on distance; - the international exchange, .e. the switching part of the international circuit plus the terminal transmission equipment; the national extension, which denotes that part of the national network of each terminal country involved in completin

17、g the connection. - - 2.1.2 In special cases where the line (transmission) part of an intemational connection is: - a radio link; or - a satellite link, the provisions of this Recommendation with regard to the determination of an accounting rate share in relation to the length of the international c

18、ircuit are not applicable and accounting rate shares should be agreed upon among the Administrations concerned. 2.2 Calculation of distances (line part) 2.2.1 Distances to be taken into consideration 2.2.1.1 General case In determining the share payable to a country for the use of international circ

19、uits, the distance to be taken into consideration is, in principle: 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 transir country - the crowflighr

20、distance between the two frontier points at which the international circuit enters and leaves the country in question. I) The standard rates given in this Recommendation are expressed in gold francs. In accordance with the International Telecommunication Regulations, the gold franc is equivalent to

21、113.061 SDR. Recommendation applicable to the African Region. Recommendation D.601 R (10/93) 1 ITU-T RECMN+D-b01R 93 4862591 0592194 104 The above provisions for the calculation of distances apply to international circuits both on land cables and on radio- relay links. 2.2.1.2 special cases 2.2.1.2.

22、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, the frontier point for measuring the circuit length shall be the point midway b

23、etween the two relay stations on either side of the frontier. 2.2.1.2.2 Submarine cables With regard to international circuits which are routed in submarine cables, the distance to be used for accounting shall be calculated as follows: a) for the land section of the circuit to the submarine cable st

24、ation, the distance shall be calculated in accordance with the general principles (i.e. the crowflight distance), it being assumed that the point at which the circuit crosses the frontier is the cable station; for the submarine cable section, the distance used shall be the actual route distance betw

25、een the submarine cable stations, as determined and agreed by the owners of the cable; the distance will be divided appropriately (normally 50/50) between the countries at the extremities of the cable. b) 2.2.1.2.3 Special itineraries In exceptional circumstances, multiplication factors may be appli

26、ed to the crowflight distance, from which the terminal and transit charges are calculated, to take account of special itineraries. For example, in the case of a direct transit country, the crowflight distance between the points on the frontier at which the circuit enters and leaves the country may (

27、in exceptional circumstances) be replaced by a length representing the sum of two crowflight segments making up a broken line, etc. 2.2.2 Possibility of weighting distances For calculation of the crowflight distances for the international section, a weighting according to the number of circuits is n

28、ormally 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 intemational exchanges in a country for the relation concerned. - - This weighting serves to determine

29、 a length (crowflight distance) for fixing the accounting rate shares relating to the international section and shall remain in force as long as the structure of the network is not significantly changed. This length of the international section is then used to fix the international section element f

30、or the charges for international telex circuits. 2.2.3 Rounding off distances 2.2.3.1 Example: distance of 24 km rounded up to 50 km. Distances less than 50 km shall be rounded up to 50 km. 2.2.3.2 Examples: - - - Other distances shall be rounded to the nearest multiple of 50 km. distance of 72 km r

31、ounded to 50 km; distance of 126 km rounded to 150 km; distance of 175 km rounded to 200 km. 2.2.3.3 This rounding rule applies to the distances in each of the terminal countries and in each of the transit countries and is applied to the total distance calculated for any one country. It is applicabl

32、e 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. 2.2.3.4 only after the weighted distance has been calculated. When distances are weighted in accordance with the provisions of 2.2.2 above, the roundin

33、g shall be applied 2 Recommendation D.601 R (10193) ITU-T RECMN*D.bOLR 93 = 4862593 0592395 040 2.2.4 When, in a given relation, there are several routes traversing different transit countries, these transit countries shall in ail cases receive the share or flat-rate price normally due to them for t

34、he 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 transit countries. Existence of s

35、everal routes in a given relation 2.3 For international accounting purposes, there are two methods of remuneration for the facilities made available by Administrations: Standard rates to be applied for internationai accounting - - Remuneration on the basis of traffic units on the basis of traffic un

36、its; on the basis of a flat-rate price for the facilities made available. 2.3.1 To determine the accounting rate shares for each country, the following standard rates, per minute of telex call, are recommended; however, these rates represent a maximum which Administrations undertake not to exceed. 2

37、.3.1.1 Remuneration of the international network in semi-automatic and automatic operation - per I00 km of international circuit (excluding any national circuit required for connecting the international exchange to for the semi-automatic international exchange in the country of origin for the automa

38、tic international exchange in the country: of origin 9.3 gold centimes of destination . for an automatic international exchange in a transit country . the national exchange serving the subscriber) . O. 18 gold centimes2) - - 61.2 gold centimes . 9.3 gold centimes - Remuneration of the national exten

39、sion 18.4 gold centimes 2.3.1.2 An amount may be added to cover the costs of the extension of calls over the national network. This amount should be determined by the Administration of each country after consideration of the volume and distribution of traffic on the national extension in its country

40、 for each relation concerned. It is recommended that as a general rule this amount should not exceed 50 gold centimes per minute. This amount is considered as covering the costs of accounting operations as well as the costs of switching and transmission over the nationai extension. 2.3.2 2.3.2.1 2.3

41、.2.1.1 To determine the flat-rate price for remuneration for the transmission facilities made available by Administrations, the following standard rates are recommended; however, these rates represent a maximum which Administrations undertake not to exceed: Per year and per 100 km of transmission ch

43、are connected in a direct transit country, an additional charge of i0 gold centimes shall be made for the translating equipment used to connect them. 3, Where, in order to establish a circuit, two telegraph channels in a direct transit country are connected, an additional charge shall be made for th

44、e lease of the transmission equipment for two telegraph channel extremities, i.e. loo0 x 2 = 2000 gold francs, irrespective of the number of such connections in the direct transit country. Recommendation D.601 R (10/93) 3 ITU-T RECMN*D.b01R 93 4862591 059219b T87 2.3.2.1.2 When a circuit leased to a

45、 private user passes through a direct transit country, the Administration of this country will be remunerated by the Administrations of the terminai countries with a flat-rate price on the same basis as if the circuit were an ordinary public service circuit applying the rate in 2.3.2.1.1 above. 2.3.

46、2.2 To determine the flat-rate price for remuneration of the country of destination for the facilities made available by Administrations, the following standard rates are recommended; however, these rates represent a maximum which Administrations undertake not to exceed: Remuneration of a country of

47、 destination I) For the transmission channel (line part) Per year and per I O0 km - per 50-baud telegraph channel 54 gold francs - per VFT telephone bearer circuit 1300 gold francs For the intemational exchange (including the terminal transmission equipment) - 2) per year and per 50-baud internation

49、tion of collection charges in telex relations between countries in Africa 3.1 General The establishment of the collection charge is a national matter. Although, in general, Administrations correlate collection charges and accounting rates, the two will not necessarily be the same for a number of reasons, for example: a) b) c) d) e) f) in most countries, collection charges and accounting rates will be expressed in different currencies; collection charges and accounting rates may be based on different traffic units; the value of national currencies may fluctuate relative to the gold franc;
