FOREWORD The IT-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The I
3、TU-T is responsible for studying technical, operating and tariff questions and issuing Recommen- dations 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 f
4、or study by the IT-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the IT-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993). IT-T Recommendation (2.2, was revised by ITU-T Stud
5、y Group 1 (1993-1996) and was approved by the WTSC (Geneva, October 9-1 8, 1996). NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

8、Geneva, 1996) The IT-T, considering a) b) Article 1 of the Constitution (Geneva, 1992) and Article 15 of the Convention (Geneva, 1992); Article 8 of the International Telecommunication Regulations (Melbourne, 1988); c results of the ITU-T studies undertaken pursuant to that Resolution; Resolution 21
9、 adopted by the World Telecommunication Standardization Conference (Helsinki, 1993) and the 4 Union (Kyoto, 1994), Resolutions 39, 65 and 66 adopted by the Plenipotentiary Conference of the International Telecommunication recognizing a) that the TSBs collection and dissemination of official service
10、information of an administrative, operational, ariff and statistical nature (hereinafter referred to as oficial service information) assists Administrations and ROAs in their efficient administration and provision respectively of international telecommunication services; b) information; that the ITU
11、 Operational Bulletin has provided an effective method of promulgating much of this type of c view to cost-effectiveness as regards the burden both: that the decision for the IT-T to collect and to disseminate official service information should be taken with a - - on Administrations and ROAs in pro
12、viding the information; and on the TSB in the preparation and dissemination of that information; d) that ROAS also exchange information of an operational nature directly among themselves, and that in some cases (e.g. where many ROAs are affected) some standardization of the content and/or format of
13、the information exchanged may be desirable, recommends that the following general principles should be applied regarding the collection and dissemination of service information, particularly the oficial service information disseminated by the TSB. 1 Service information requirements 1.1 arrangements)
14、 for collection and dissemination of service information: Whenever a Study Group identifies a new requirement (or the need for a major change in the existing a) it should consider whether the relevant ROAs (andor Administrations) should communicate such service information among themselves directly;
15、 or if IT involvement is desired, the Director of the TSB shall be consulted concerning the justification for that involvement, taking into account the perceived market needs, ITU budget considerations, and any other IT administrative implications before proceeding. b) 1.2 In cases a) and b), the re
16、quirement should be laid down within ITU-T Recommendations. The relevant Recommendation should speciy unambiguously and at least in general terms the nature of the different types of information required. Where appropriate, it may also speciSl the format, periodicity, entry into effect, andior proce
17、dures for updating the relevant service information. Recommendation C.2 (10/96) 1 STD-ITU-T RECMN C.2-ENGL L79b = Lid62571 Ob31774 37i D 1.3 In case a), the information exchanged is not regarded as oficial service information. Nevertheless, in some cases it may be appropriate to speci that each sour
18、ce ROA (or Administration) should supply a copy of the information or a summary of it to the TSB. 1.4 provisions at least once towards the end of each period between two WTSCs. Each Study Group responsible for the maintenance of such Recommendations shall review the relevant 2 Collection of data for
19、 official service information 2.1 The Director of the TSB should request Administrations and/or ROAs to supply official service information, or any changes to previously supplied information, for dissemination in accordance with the provisions of the relevant Recommendations. The form of the request
20、 should be designed to minimize the effort required of the Administrations and/or ROAs in providing the information requested. 2.2 Administrations (and/or ROAs) should reply to such requests for information, to the extent practicable, in a timely fashion and in accordance with national arrangements,
21、 taking due account of the confidentiality of possibly commercially sensitive information. 2.3 Upon receipt of a request for official service information, Administrations may elect (on a case-by-case basis or an until-jrther-notice basis), in accordance with national practice, to make arrangements t
22、o collate replies from their ROAs. Any Administration exercising such election shall notify the Director of the TSB. Absent such election and notification, the TSB should expect individual replies from the ROAs. In processing the individual replies, the TSB shall consider them as emanating from an R
23、OA duly authorized by the relevant Member (or its Administration) to offer the relevant telecommunication service(s) to which the request for information pertains. 3 TSB administrative support 3.1 The Director of the TSB provides advice and support to the various Study Groups responsible for the Rec
24、ommendations requiring the collection and dissemination of official service information, in particular as outlined in 1.1,2.1 and 2.3 above. 3.2 In addition, and in view of the responsibilities vested in his office, the Director makes suitable arrangements: a) b) to establish and to keep up to date,
25、 for each Study Group, a list of those Recommendations that require the collection and dissemination of official service information; to submit such a list to each Study Group concerned on request, and in any case at least twelve months prior to a WTSC, for possible revision (amendments, additions a
26、nd/or deletions) in the light of operational experience; to ensure that the method of disseminating official service information reflects technical developments in the means of collecting and exchanging such information and that the most appropriate and economic solutions are adopted, while taking d
27、ue account of the needs of countries where electronic access to ITU databases, for example, is not yet available; to establish and to keep up to date on the basis of the responses returned, a list of the relevant service and/or network providers that have provided the official service information an
28、d whether their status is that of an Administration, ROA or other entity. c) d) 2 Recommendation C.2 (10/96) STD-ITU-T RECMN C-2-ENGL L79b = LiBb257L Ob3L775 200 Series A Series B Series C Series D Series E Series F Series G Series H Series I Series J Series K Series L Series M Series N Series O Ser
