9、ourceITU-T Recommendation D.176 was revised by ITU-T Study Group 3 (1997-2000) and was approved under the WTSCResolution No. 1 procedure on the 11th of December 1997.ii Recommendation D.176 (12/97)FOREWORDITU (International Telecommunication Union) is the United Nations Specialized Agency in the fie
10、ld of telecommuni-cations. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T isresponsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view tostandardizing telecommunications on a worldwide basis.
11、The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes thetopics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.The approval of Recommendations by the Members of the ITU-T is covered by the procedure
12、 laid down in WTSCResolution No. 1.In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on acollaborative basis with ISO and IEC.NOTEIn this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommun

The ITU takes no position concerning the evidence, va

18、revised in 1992 and 1997)1 Introduction1.1 Under the provisions of Recommendation D.174 where the chargeable duration of a reversed charge telephonecall is determined in the outgoing country, the details of the call should be transmitted promptly to the distantAdministration to enable it to perform
19、customer billing and in certain circumstances (see 4.3/D.170) initiate internationalaccounting.1.2 A growing number of Administrations are processing telephone call data using computer-based accountingsystems. Information is drawn from traffic history tapes or from manually encoded data such as tele
20、phone tickets. It isusual, at present, to convert computer output from this processing to conventional printed accounts for dispatch to otherAdministrations. Where the receiving Administration also uses computer facilities, however, this information has to bere-encoded for further processing.1.3 Tra
21、nsmission of data in encoded form avoids the decoding/re-encoding step. It also offers a faster transfer ofinformation than by printed forms through the mail. The latter remains true even if the forwarding Administration hasprepared the data by manual/mechanical means.2 Aim2.1 The aim of this Recomm
22、endation is:2.1.1 to enable Administrations using computer-based accounting systems to transfer information to each other inencoded form, without the need for decoding into conventional printed form and subsequent encoding into machine-readable form;2.1.2 to enable other Administrations, if they so
23、desire, to benefit from the greater efficiency of speedier transfer ofinformation to them and to prepare themselves for the introduction of computer working by introducing transmission ofdata in encoded form in advance of the installation of a computer;2.1.3 to facilitate provision of printed output
24、 from computer-based systems in a format suitable formanual/mechanical processing where it is to be forwarded to Administrations not using computer facilities;2.1.4 to facilitate provision of printed output from manual/mechanical accounting systems in a format suitable fordata encoding where it is t
25、o be forwarded to Administrations employing computer processing.3 Method3.1 Data record3.1.1 The aim of this Recommendation can be met by use of a standard data record format for the various elementsof information to be transferred. The information elements and their sequence must be compatible with
26、 the provisions of_1The term “reversed charge“ is used to mean collect, credit card and third-number paying calls.2 Recommendation D.176 (12/97)Recommendation D.174, so that decoding to and encoding from printed output for exchange of information withAdministrations using manual/mechanical systems w
27、ill be as simple as possible.3.1.2 Between Administrations operating computer-based accounting systems, adherence to the standard data recordformat for data transmission purposes will ensure that only one interface programme will be needed to enable any onecomputer installation to generate suitable
28、input for, and accept output from, other computer installations.3.2 Data transfer3.2.1 Procedures already exist for transfer of data in conventional (printed) form through the mails. Data in encodedform could be transferred by mailing of magnetic or paper tapes, paper tape transmission by telex or d
29、ata transmissionover circuits utilized for this purpose.3.2.2 While mailing of tapes avoids the encoding task for the receiving Administration, there can be delays and lossin transit. In addition, there can be difficulties caused by the fragility of paper tape and incompatibility of various formsof
30、magnetic tape recording.3.2.3 Transfer of data via the telex service using paper tape transmission and reception can be advantageous forAdministrations whether they have computer-based accounting systems or manual/mechanical systems. As both pagecopy and punched paper tape can be generated at the re
31、ceiving point, users of either type of accounting system canbenefit. Page copy can be used for checking paper tape with the latter becoming input to a computer. Page copy can alsobe used as the source of information for preparation of customer billing in a manual/mechanical system.3.2.4 Where large
32、volumes of data are to be exchanged, transmission over higher speed circuits offers significantbenefits. Where suitable data links are in use for service transmission, these could be utilized. Data terminals andmodems capable of transmission speeds in the range 600 to 2400 bits per second should be
33、sufficient but higher speedscould be used. For manual/mechanical systems, data received on data terminals can be reproduced as page copy for theproduction of customer billing. For computer-based accounting systems, data transmission offers the possibility ofcomplete automation of the process by comp
34、uter-to-computer transfer.4 Specific recommendations4.1 It is recommended that:4.1.1 Where possible, data transferred in printed form should be placed in the order shown in A.2.4.1.2 For transfer of data in encoded form, the standard data record format detailed in Annex A should be followed.4.1.3 Tr
35、ansmission of data in encoded form should be by the following means:a) use of the telex system;b) use of data transmission over telephone circuits, dedicated telegraph circuits or special data links.4.1.4 Transmission speeds, operating practices and technical standards should be agreed between theAd
36、ministrations concerned and should conform with the appropriate ITU-T Recommendations.5 Code maintenanceThe TSB is responsible for maintenance of the record of codes used for Items 1, 2, 6 and 7 of the Detail record shown inAnnex A.New codes can be allocated by the authority of the Director of the T
37、SB.
