12、n 1 approval procedure. ii ITU-T Rec. D.4 (09/2005) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for stu
13、dying 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 four years, establishes the topics for study by the ITU-T study gro
14、ups 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, the necessary standards are prepared on a collaborative basis with
15、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. However, the Recommendation may contain certain mandatory provisi
16、ons (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 negative equivalents are used to express requirements. The use of such
17、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 use of a claimed Intellectual Property Right. ITU takes no position
18、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, ITU had not received notice of intellectual property, protected
19、by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2005 All rights reserved.

D.4 (09/2005) 1 ITU-T Recommendation D.4 Special conditions for the lease of international (continental and intercontinental) sound- and television-programme circuits for private service 1 General principles 1.1 The general principles as stated in clause 1/D.1 and clause 1/D.18
24、0, where applicable for leased international sound- and television-programme circuits, shall serve as the general principles for this Recommendation. The Administrations concerned may agree upon additional principles, if desired. 1.2 This Recommendation is intended to cover the use of circuits for s
25、ound- and television-programme transmission purposes only, unless otherwise agreed upon by the Administrations providing the circuits. 2 Definitions The definitions applicable to the lease of sound- and television-programme circuits are contained in clause 3/D.180. Illustrative diagrams of such circ
26、uits are included herewith as examples for reference purposes. It should be noted that these diagrams, which are extracts from ITU-T Rec. D.180, do not cover all situations (e.g., leased sound- and television-programme circuits are not always routed by the International Sound-Programme Centres (ISPC
27、s)/International Television-Programme Centres (ITPCs). 2.1 Constitution of sound- and television-programme connections See Figures 1 and 2. Figure 1/D.4 Example of an international sound-programme connection 2 ITU-T Rec. D.4 (09/2005) Figure 2/D.4 Example of an international television-programme con
28、nection involving a satellite circuit 3 Duration of the lease, charging and cancellation 3.1 This Recommendation applies to sound- and television-programme circuit leases for minimum periods as established by Administrations. This Recommendation shall apply to leases lasting normally not less than 2
29、4 hours, taking into account the availability of the communications facilities used in the provision of these circuits (e.g., facilities may not be available in all cases for short-term use). If a circuit is cancelled at the request of a customer prior to the end of either the ordered or the minimum
30、 lease period, special charges may be applied as a result of early termination. 3.2 In the provision of leased sound- and television-programme circuits, Administrations should take into account the provisions of clause 5/D.1, where applicable. 3.3 In establishing the charges for leased sound- and te
31、levision-programme circuits, Administrations should take into account the provisions of clause 6/D.1. 3.4 Administrations shall specify the period of notice required for cancellation prior to the initiation of service. 3.5 In the case of leased television-programme circuits, chargeable periods may c
32、ommence on the day a circuit is activated and continue through the last day a circuit is furnished. 3.6 In calculating the chargeable terrestrial circuit lengths, Administrations shall apply the arrangements in 6.5/D.180. In special cases, Administrations may agree among themselves upon the ITU-T Re
33、c. D.4 (09/2005) 3 chargeable circuit lengths (e.g., for submarine cables, radio-relay links with difficult terrain conditions, transit circuits, etc.). 3.7 Administrations may establish additional charges for special services rendered at the request of customers. Examples of these special services
34、are: the provision of leased programme circuits which are adapted for multiple use by means of equipment provided by Administrations; the provision of switching units at the ends of leased programme circuits to allow their connection with other circuits, e.g., with occasionally provided programme ci
35、rcuits; reversals in the direction of transmission; the establishment of special categories of circuits. 4 Ordering of circuits and conditions of acceptance 4.1 Orders 4.1.1 Each order, which should be clearly identified as such, carries with it an undertaking to pay all the charges relating to the
36、use of the facilities ordered, including any cancellation fee or special expenses which may be incurred in connection with the order. 4.1.2 The Programme Booking Centre (PBC) receiving orders should confirm acceptance and availability of circuits as soon as possible. 4.1.3 The broadcasting organizat
37、ions should be entitled, prior to the date of provision, to enquire from their Administration information on all special expenses accruing for the provision of circuits for international sound- and television-programme transmissions. A cost estimate of all special national expenses and international
38、 expenses should be submitted to the broadcasting organizations before placing a circuit order. 4.2 Handling of enquiries and orders received by Administrations 4.2.1 The Administration which receives an enquiry either about a cost estimate or a circuit order is responsible for passing on this enqui
39、ry about a cost estimate or the circuit order to all Administrations involved in order to obtain from them a cost quotation or an order acknowledgement for the requested circuits and equipment. Enquiries about cost estimates should normally be made and answered before a circuit order is placed. If n
40、o enquiry concerning a cost estimate was made, the order acknowledgement should contain information on all national special expenses for the transmissions ordered. 4.2.2 Facilities for sound- and television-programme transmissions should be allocated in the sequence in which orders are received. 4.2
41、.3 For the provision of circuits via satellite: a) the Administration receiving the order is responsible for arranging the circuits between the broadcasting organization and the appropriate ITPC at the end of the satellite circuit (SITPC); b) the Administration operating this ITPC is responsible for
42、 confirming the availability of the satellite circuit and for ordering its portion of that circuit; and c) the Administration operating the ITPC at the other end of the satellite circuit is responsible for ordering its portion of the satellite circuit and for arranging the circuits between its ITPC
43、and the other broadcasting organization. 4 ITU-T Rec. D.4 (09/2005) This procedure normally applies to sound-programme and control circuits provided by means of satellite channels specially assigned for use in association with television transmissions but not necessarily to other sound-programme cir
44、cuits provided via the satellite or to sound-programme circuits provided by any other means, e.g., submarine cable. 5 Collection of charges Accounting 5.1 Collection of charges In principle, the Administration with which the order was placed is responsible for collecting the charge for the provision
45、 of circuits from the broadcasting organization which placed the order. 5.2 Remuneration of Administrations The Administration with which the order for the provision of circuits is placed is responsible for the remuneration of all other Administrations involved. For this purpose, all such other Admi
46、nistrations should send to the Administration responsible for collecting charges, the relevant details concerning the provision of the circuits and the amounts corresponding to their credits with monthly invoices. Invoices shall be sent at the latest within 50 days following the end of the month in
47、which the circuits for the sound and television-programme transmissions were provided. The invoices should additionally contain: Address of debtors Administration; Address of creditors Administration; Contact details of creditors Administration (e.g., electronic mail address or facsimile number); Ba
48、nk contacts; Name of the bank; Address of the bank; Account number; SWIFT code; IBAN (International Banking Account Number). 5.2.1 The debtors Administration is entitled to reject incomplete invoices which do not contain the data defined in 5.2. These invoices will be returned for correction to the
49、creditors Administration. 5.2.2 In order to facilitate the smooth exchange of the relevant details concerning the provision of the circuits and the amounts corresponding to their credits, the creditors Administration may issue invoices in electronic format in addition to paper-based invoices. 5.3 Special conditions for temporarily leased circuits The Administration responsible for the collection of charges may refuse to make any settlements of invoices presented by other Administrations more than 12 months after the date at
