12、.2 ITU-T D.170 Suppl.2 2010-05-21 3 ii Rec. ITU-T D.170 (05/2010) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector
13、(ITU-T) is a permanent organ of ITU. 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 Assembly (WTSA), which meets every fo
14、ur years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, th
15、e necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary.
16、However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negat
17、ive equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the us
18、e of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation
19、, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/ww

24、U-T D.170 (05/2010) 1 Recommendation ITU-T D.170 Monthly telephone and telex accounts 1 General 1.1 The following arrangements are recommended for the drawing up, exchange and acceptance of monthly telephone and telex accounts between Administrations. 1.2 Each Administration of origin (and of transi
25、t where appropriate, e.g., in the case of clause 3.1.4 below) shall prepare and forward monthly accounts. These should be drawn up separately on forms of the types shown below as specimens for: a) telephone traffic proper Forms 1 or 2 (see Annex A); b) sound- and television-programme and phototelegr
26、aph transmissions Forms 1 or 2 (see Annex A) suitably adapted; c) telex traffic Forms 1 or 2 (see Annex B). 1.3 The choice of form to be used for the accounts should be decided by the Administration which prepares the accounts, after consultation with the other Administration concerned. It may be co
27、nvenient to use separate forms for originated and transit traffic. 1.4 The traffic details which must be included in the account are only those which are necessary for the purpose of international accounting. However, by agreement between the Administrations concerned, traffic information which is n
28、ot essential for the accounts (e.g., the number of calls where this does not affect the accounting) may be included on the account forms. 1.5 Monthly accounts should be sent as promptly as possible in time periods specified in the International Telecommunication Regulations and, if mutually agreed,
29、Rec. ITU-T D.195. 2 Accounts in international relations where Recommendations ITU-T D.67 and D.150 apply The preparation of the monthly telephone accounts shall be as follows, using as an example the diagram in Figure 1 which is a reproduction from Annex B of ITU-T D.150. This diagram relates to the
30、 traffic from terminals A to B. Figure 1 Typical pattern of circuit interconnections between various countries 2 Rec. ITU-T D.170 (05/2010) 2.1 When the accounting revenue division procedure is applied for accounting between A and B 2.1.1 For traffic on the direct route, A to B A shall prepare and f
31、orward to B a monthly account crediting B with one half of the net revenue (accounting revenue) (or whatever amount is mutually agreed between the parties), after deduction of the amounts due from A to C and D. A shall also account with C and D, either by including their remuneration in the monthly
32、accounts for traffic from A which terminates in each of these countries, or by sending them a copy of the monthly account prepared for B, showing in it the amounts due to C and D. 2.1.2 For traffic on the route, A to B via E There are two possibilities: 1) When the rate quoted by E includes an amoun
33、t due to B: A shall prepare and forward to E a monthly account crediting E for As traffic to B via E at the rate quoted by E to cover the transit of E (and of D or F) and also for the destination country B. In principle, A should include in its monthly account to B an amount crediting B with the app
34、ropriate share (normally one half) of the gross revenue from this stream of traffic minus: a) the appropriate share (normally one half) of the amount due from A to E for the transit of E (and of D or F); and b) the whole of the amount due from A to E for the destination country B. (For a better unde
35、rstanding of these procedures, see Annex B of ITU-T D.150, in particular.) 2) When the rate quoted by E does not include an amount due to B: A shall prepare and forward to E a monthly account crediting E for As traffic to B via E at the rate quoted by E to cover the transit of E and of D or F. A sha
36、ll also include in its monthly account to B an amount crediting B with the appropriate share (normally one half) of the net revenue after deduction of the amounts due (normally one half) from A to E (the amount covering the transit by E and D or F regardless of the method of repayment: flat-rate or
37、traffic-unit price procedure). 2.2 When the accounting revenue division procedure is not applied for accounting between A and B 2.2.1 For traffic on the direct route A to B A shall prepare and forward to B, C and D, respectively, a monthly account crediting the amounts due from A to each of them und
38、er whatever accounting procedure has been agreed with each of them (i.e., either the traffic-unit price or the flat-rate price procedure). If the country of destination is remunerated under the traffic-unit price procedure, the flat-rate amounts for direct-transit countries should be divided into ap
39、propriate shares (normally equal) between the two terminal countries and the traffic-unit per minute price for passage through those transit countries should be divided in the same proportion between the two terminal countries. The application of this rule is necessary if the traffic accounting betw
40、een the two terminal countries is to be fair, as this traffic-unit per minute price should be used by each terminal Administration as a factor to be multiplied by the volume of outgoing traffic, which may not be the same in the two directions. Thus A will credit to B the traffic-unit price of B plus
41、 the appropriate share (normally one half) of the traffic-unit price attributable to the transit of C and D. Rec. ITU-T D.170 (05/2010) 3 2.2.2 For traffic on the route A to B via E A shall prepare and forward to E a monthly account crediting E for all As traffic to B via E, at the rate quoted by E
42、to cover both: a) the transit of E and of D or F respectively; b) the remuneration due to B. A shall not include this traffic in its monthly account with B. 2.3 Accounting to be done by E in the cases described in clauses 2.1.2 and 2.2.2 E shall prepare and forward to D, F and B, respectively, a mon
43、thly account crediting to each of them the amounts due to them in respect of traffic originating in E, and shall include in these accounts the amounts due to them for traffic from A (and any other countries transited by E). However, if the method of remuneration from E to either D, F or B is flat-ra
44、te price procedure, then E shall in principle retain the amount received from A (or any other countries upstream from E) relating to the section through the country being remunerated by the flat-rate price procedure. 3 Preparation of accounts for relations to which Recommendations ITU-T D.67 and D.1
45、50 do not apply 3.1 The following provisions apply to certain international relations to which Recommendations ITU-T D.67 and D.150 do not apply. 3.1.1 In direct relations, the Administration of origin shall prepare and send a monthly account to the Administration of destination. 3.1.2 Where transit
46、 relations within the continent of origin are concerned, the Administration of origin shall prepare and send the monthly account to the Administration controlling the intercontinental circuit in the outgoing direction. At the same time, a copy of the account shall be sent to each of the Administrati
47、ons of transit countries concerned. The account shall show the share accruing to each of the Administrations of transit countries and in addition, in one amount, the share due to the Administration controlling the intercontinental circuit in the outgoing direction and the Administrations beyond its
48、territory. 3.1.3 The Administration controlling the intercontinental circuit in the outgoing direction shall prepare and forward a monthly account, both for traffic which originates in its own country, and for that which passes in transit through its own territory, showing in one amount the share du
49、e to the Administration operating the other end of the intercontinental circuit and, where applicable, the shares accruing to the Administrations beyond its territory. 3.1.4 The Administration operating the other end of the intercontinental circuit shall, where applicable, prepare a new account for each Administration concerned beyond its territory showing the share due to each. 3.2 In continental relations, except those covered by clause 2.1 above, the Administration of origin shall prepare and send a mon
