13、ion Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff ques

14、tions 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 groups which, in turn, produce Recommendation

15、s 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 ISO and IEC. NOTE In this publication, the

ITU-T D.170/Suppl.3 (01/2012) Introduction Objective The objective of this supplement is to assist those telecommunication operators who do not currently have an international interconnection agreement by specifying a possible structure of the terms and conditions to be r

24、eflected in an international interconnection agreement. Benefits of standardizing guidelines The benefits that the supplement is envisioned to bring to the telecommunication operators are as follows: Help in the formulation by telecommunication operators of an international interconnection agreement

25、, if none is yet in place. Ensure efficiency in managing accounts. Role of an international interconnection agreement For the purposes of this document, an international interconnection agreement is a commercially negotiated, legally binding, contract that defines and establishes the rights and obli

26、gations between two parties in the provision of voice services. The agreement describes the various dimensions of the business relationships, which may include the following: Effective dates Legal existence of parties to agreement Definitions of specific terms used Background to the agreement Provis

27、ion of subjected services Legal aspects: liability, representations and warranties, confidentiality and reference to specific laws Dispute handling Suspension of service Technical details of interconnection among cost-sharing models Billing and charging principles Settlement and payment methods, etc

28、. Important factors in international interconnection agreements Cost sharing on physical interconnection Charging principles for voice traffic Service definitions, i.e., products being covered Rates and numbering plan Chargeable duration Mode of traffic declarations Billing, settlements and payment

A credit policy serves as the basis on which major terms and conditions are put in place for any international interconnectio

36、n agreement. 5.2 Types of draft annexes Depending on the profile, credit policy, and customer segmentation of the prospective interconnection partner, the following drafts can be adapted (in consideration of other contract provisions) as example templates: 1. A standard draft covering post-payment t

37、erms 2. A standard draft covering post-payment terms that require credit limits and/or bank guarantees 3. A standard draft covering prepayment terms 4. A standard draft covering netting. 2 Rec. ITU-T D.170/Suppl.3 (01/2012) 5.3 Standard draft covering post-payment terms A standard international inte

Cost sharing on physical interconnection Visibility of costs associated with getting the interconnection live Should have a diagram

39、that clearly identifies different cost legs. Should clearly define responsibility for costs for both the parties (costs can also be defined in terms of percentages). Responsibility for procurement of the interconnection facility can also be covered under this item. Charging principles for voice traf
