ITU-T RECOMMENDATION D.150 NEW SYSTEM FOR ACCOUNTING IN INTERNATIONAL TELEPHONY Summary This Recommendation sets out various proc
9、edures for remuneration destination and transit Administrations for international telephone communications. The addition of three new remuneration procedures adapted to the new market condition is proposed. These are: the settlement rate procedure, the termination charge procedure and a third proced
10、ure, called special arrangements.

11、(International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing R
12、ecommendations 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
13、topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this R
14、ecommendation the term recognized operating agency (ROA) includes any individual, company, corporation or governmental organization that operates a public correspondence service. The terms Administrution, ROA and public correspondence are defined in the Constitution of the ITU (Geneva, 1992). INTELL

Recommendation D.150 NEW SYSTEM FOR ACCOUNTING IN INTERNATIONAL TELEPHONY (Mar del Plata, 19
27、68; amended at Melbourne, 1988; revised in 1992, 1996 and 1999) 1 General considerations 1.1 Introduction 1.1.1 The introduction of automatic and semi-automatic operation entails the use of alternative and overflow routings which make it impracticable to follow the path of a telephone call without c
28、onsiderable technical complications. 1.1.2 In order to avoid complicating too much the new technical equipment required and thereby raising its cost, new procedures are required so as to eliminate the need to know the path of every call as the basis for accounting in international telephony. 1.1.3 T
29、here is also the situation in certain international relations whereby Administrations purchase or lease direct transit circuits for the handling of their traffic. 1.1.4 The following procedures to meet these new situations and improve the efficiency of the world telephone network are valid, above al
30、l, for semi-automatic and automatic operation. They can be applied on relations operated manually, subject to agreement between the Administrations of all the countries concerned. 1.1.5 These procedures introduce the new concept of remunerating the Administrations of countries of destination and tra
31、nsit for making telephone network facilities available for use (e.g. for the routing of telephone calls including those with special facilities and calls indistinguishable from telephone calls such as facsimile transmission, etc.) by Administrations of countries of origin. 1.2 Explanation of some of
32、 the terms and expressions used in this Recommendation 1.2.1 Except for the expression “conversation time“ which is defined in 1.2.2 below, an explanation of some of the terms or of some of the expressions used in this Recommendation is given in Recommendation D.OOO. 1.2.2 conversation time F: dure
33、de conversation S: duracin de conferencia A minute of conversation time is the traffic unit that is recommended for use in the traffic unit price procedure. Conversation time is the interval that elapses between: - the moment when the reply condition (answer signal in the backward direction) is dete
34、cted at the point where the recording of the call duration takes place; and the moment when the clear forward condition (clear forward signal) is detected at the same point. - Recommendation D.150 (06/99) 1 1.3 Basic principles of a new system for accounting in international telephony 1.3.1 The remu
35、neration of the Administrations of transit countries (direct transit or switched transit) should not depend upon the procedure selected by the terminal Administrations for accounting for their remuneration. That is, the different procedures affect only the remuneration of terminal Administrations. 1
36、.3.2 As regards the remuneration of the Administrations of the countries of destination and transit countries, it is preferable to make no distinction between automatic and semi-automatic traffic when establishing international accounts. This is in line with the idea that Administrations should be r
37、emunerated on the basis of the facilities made available. Whilst expenses of setting up calls in these two cases are different in countries of origin, they are approximately the same in the countries of destination and transit countries. 1.3.3 It is preferable, in order to simplify accounting, that
38、one procedure or the other be used to the greatest possible extent. Certain regions may find it expedient to select one of the procedures for use within their region. 1.4 Procedures Procedures relating to remuneration of Administrations of destination and transit countries are as follows: 1.4.1 Admi
39、nistrations of countries of destination will be remunerated, either by: 1.4.1.1 a procedure whereby the Administration of the country of origin keeps its revenue and remunerates the Administration of the country of destination for the facilities made available, including the international circuit, t
40、he international exchange and the national extension I: a) b) in either case, the price will be fixed by the Administration of the country of destination; or by: 1.4.1.2 the procedure whereby accounting revenue is shared between terminal Administrations (called the accounting revenue division proced
41、ure). 1.4.2 Remuneration of transit countries 1.4.2.1 For direct transit operation between two terminal Administrations, the Administration of transit countries will be remunerated for facilities made available according to the flat-rate price procedure. 1.4.2.2 For switched transit operation betwee
42、n two terminal Administrations, the Administration of the first transit exchange will be remunerated for facilities made available according to the traffic- unit price procedure. Other transit Administrations involved will be remunerated by the Administration of the first transit exchange using the
43、flat-rate price procedure for direct transit circuits or the traffic-unit price procedure for switched transit facilities. Remuneration of countries of destination on the basis of a flat-rate price per circuit (called the flat-rate price procedure); or on the basis of traffic units carried (called t
44、he trafic-unit price procedure); Having due regard, as concerns this element, to the location of the international exchange and the distribution of the international traffic within the country of destination. 2 Recommendation D.150 (06/99) STDaITU-T RECMN D-L5O-ENCL 1994 = 4Bb2591 Obb2205 T74 1.4.3
45、Remuneration of the country of origin For the remuneration of the country of origin, see clause 4. 1.5 Traffic unit 1.5.1 Definition of the traffic unit - Conversation time It is recommended that, when the traffic-unit price procedure is used see 1.4.1.1 b) and 1.4.2.2 above, the traffic unit adopte
46、d for the purpose of remunerating other Administrations should be one minute of conversation time. 1.5.1.1 With regard to a call, conversation time is the interval that elapses between: - the moment when the reply condition (answer signal in the backward direction) is detected at the point where the
47、 recording of the call duration takes place; and the moment when the clear forward condition (clear forward signal) is detected at the same point. 1.5.1.2 The above duration conforms to that in Recommendations E.230 i and E.260 2 for the “call duration“ of automatic calls; it is now to be applied to
48、 all calls covered by this Recommendation. In practice, the reply condition is detected by recognition of the answer signal generated upon answer of the called party or distant operator. The clear forward condition is detected by recognition of the signal generated by the calling party or outgoing o
49、perator clearing down the connection. In default of such action, the connection will be automatically cleared down and a clear forward signal generated in the outgoing exchange after a delay period following receipt of the clear back signal generated by the called party replacing the receiver. measured automatically in response to signals generated by ITU-T signalling systems. Furthermore, it allows accounts to be settled by an Administration of a transit country without waiting for information from countries “up the line“ as regards call durations taken from data o
