2、NFERENCING SERVICE Recommendation D.188 CCITT RECMN*D.LBB 92 m 4862593 0576443 Lt85 = FOREWORD The CCITT (the International Telegraph and Telephone Consultative Committee) is a permanent organ of the Iiiterriational Telecommunication Union (ITU). CCITT is responsible for studying technical, operatin
3、g and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications 011 a worldwide basis. The Pleiiary Assembly of CCITT which meets every four years, establishes the topics for study aid approves Recoinmendations prepared by its Study Groups. The approval of
4、Recominendatioris by the members of CCITT between Plenary Assemblies is covered by the procedure laid down iti CCITT Resolution No. 2 (Melbourne, 1988). Recommendation D.188 was prepared by Study Group III and was approved under the Resolution No. 2 procedure on the 1st of October 1992. CCIIT NOTE I

Recommendation D.188 GENERAL CHARGING AND ACCOUNTING PKINCIPLES APPLICABLE TO AN INTERNATIONAL VIDEOCONFERENCING SERVICE (1992) Preamlile This Recommeiidaticin sets out the general principles and con
7、ditions applicable to the videoconference service. A description of the iiiteniational videoconference service can be found in the Recommendation F.730, conceniing videocnferencin%. The CCITT, cwnsidrirrg (a) that the wailability of satellite systems and terrestrial infrastructure between Administra
8、tions m,akes it possible to offer a wide range of services: (b) that current technological developments make it possible to provide audiovisunl transmission between groups of users ;it remote locations: (c) the tiecessity to meet customer needs by offering an iiiternational videoconference service;
9、(d) the need, iii so far as possible, to achieve at xi interntional level a certain h,unonization of general principles of tariffs aiid :iccountiiig applicable tu this service; (e) that besides point-to-point coiinections also multipoint connections are possible using a multipoint coiitrol unit (MCU

11、ts While the determination of customer charges is a national matter, the charges for the videoconference service - Connection churge may include one or more of the following elements: The connection charge (one-time installation charge) normally should cover the cost of connecting a private studio t
12、o the videoconference service. 1.2 Subscription churge Subscription charges for customers with private studios should normally cover the cost of providing dedicated facilities muidlor equipment at the premises of the customer. 1.3 Occusionul rise churges The occasional use charges should normally co
13、ver the cost to Administrations of the facilities used, which - the transmission capacity used; - cost could include one or more of the following: the facilities used (i.e. transmission routed via the terrestrial network or via an earth station); Recommendation D.188 (10/92) 1 CCITT RECNN*D.L88 72 W
14、 4862573 057b443 258 W - the transmission duration; - - the provision of possible transit facilities: the time of transmission (in order to allow, where applicable, for a difference in tariff depending upon the time of day); the amount of use during a fixed period; - - - MCU; where appropriate, the
15、distance between correspondents; - conversion facilities: - interconnection between different networks. 1.4 Studio churge The charges for customers using a studio provided by an Administration should normally cover the cost of providing that studio. This charge may be additional to the usage charge
16、related to the duration of the transmission. 1.5 MCU connections The charges for MCU connections should, in so far as possible, be based on a harmonized tariff structure which is independent of network configuration and location of the MCU(s). 1.6 Special urrarigernents By bilateral or multilateral
17、agreement, Administrations may agree that one Administration participating in the provision of service may bill and collect, on behalf of one or ail the Administrations providing the service, all rental and usage charges. 1.7 Currcellutiorr charge Where a customer cancels a transmission within an ag
18、reed time period, Administrations may apply a cancellation charge. 1.8 Rebate for service interruption Where a service interruption is not the fault of the customer, the customer normally will be entitled to a rebate provided the interruption has exceeded an agreed time period. Alternatively, Admini
19、strations may extend the transmission for a period equivalent to the outage, if capacity is available, or, if preferred by the customer, give the customer a corresponding credit. 2 International accounting 2.1 Accounting uriits An initial accounting unit period for international videoconferencing sh
20、ould normally be 30 minutes, with incremental periods of 15 minutes. Other accounting unit periods can be agreed bilaterally. 2.2 Administration. Normally there is no accounting between two terminal Administrations since each customer pays its own 2 Kecommendation D.188 (10/92) CCITT RECMN*D.188 92
21、48b2591 0576444 194 = 2.3 Accoiinting for trcinsit costs Where transit facilities are provided exclusively by terrestrial circuits, each terminal country should normally pay the transit country the amount due for transit expenses. This amount will be billed by the transit country to the terminal cou
22、ntries. 2.4 Normally, where transit facilities are provided by means of an earth station, the terminal country which does not use its own ecuth stiition but requests a trcmsit country to provide earth station facilities, shall pay all of the transit expenses (terrestrial circuit between the frontier
23、 and the international transmission centre and the earth station usage charges). 2.5 follows: In case of a faulty connection caused in the transit country, the international account will be reduced as a) terrestriul transit: generally no accounting payment for the whole transit connection; b) satell
24、ite rise for transit: payment of accounting for space segment charges only. 2.6 When for reasons of availability or network optimization, the Administration in one country uses an MCU in mother country for setting up a multipoint connection, it should normally pay a flat-rate MCU-access accounting-r
25、ate to the Administration providing the MCU. 2.7 nature of the service and the period to which it refers. When settling international accounts for a multipoint videoconference, Administrations shall specify the 2.8 When one Administration, on behalf of one or more Administrations collects rentals or charges under the conditions as set out in 8 1.6, these shall be credited to the other Administration(s) concerned via the international accounts by identifying the nature of the fee and the period to which it refers.
