9、NSMISSION IN ENCODED FORM OF MARITIME TELECOMMUNICATIONS ACCOUNTING INFORMATION Source ITU-T Recommendation D.91 was revised by ITU-T Study Group 3 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 1st of July 1996. FOREWORD ITU (International Telecommunication Union) is
10、the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (IU-T) is a permanent organ of the U. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standard
11、izing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the
12、 Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993). In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, th
13、e expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. O ITU 1996 All rights reserved.

21、ING INFORMATION (Melbourne, 1988; revised in 1990 and in 1996) 1 Introduction 1.1 Under the provision of Recommendation D.90, Administrations engage in international billing and accounting for radiocommunications handled each month. 1.2 A growing number of Administrations are processing this monthly
22、 intemational accounting data using computer-based billing and accounting systems. Information is drawn from traffic history tapes or diskettes or manually encoded from data, such as inward international accounts and statistical summaries prepared by manual abstraction from copies of traffic tickets
23、. 1.3 It is usual at present to complete computer processing by producing conventional printed accounts following the specifications described in the various accounting Recommendations (D.90). Where the receiving Administration also uses computer facilities, however, this information has to be re-en
24、coded for processing through its system. 1.4 Transmission of data in encoded form avoids the decodinghe-encoding step. It also offers a faster transfer of information than by printed forms through the mail. The latter remains true even if the forwarding Administration has prepared the data by manuaY
25、mechanica1 means. 2 Aim 2.1 The aim of this Recommendation is: 2.1.1 To enable Administrations using computer-based billing and accounting systems to transfer information to each other in encoded form, without the need for decoding into conventional printed form and subsequent encoding into machine-
26、readable form. 2.1.2 To enable other Administrations, if they so desire, to benefit from the greater efficiency of speedier transfer of information to them and to prepare themselves for the introduction of computer working by introducing transmission of data in encoded form in advance of installatio
27、n of a computer. 2.1.3 To facilitate provision of printed output from computer-based systems in a format suitable for manual/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 acco
28、unting systems in a format suitable for data encoding where it is to be forwarded to Administrations employing computer processing. 3 Method 3.1 Data record 3.1.1 The aim of this Recommendation can be met by use of a standard data record format for the various elements of information to be transferr
29、ed. The information elements and their sequence must be compatible with the provisions of the various accounting Recommendations so that decoding to Recommendation D.91 (07/96) 1 and encoding from printed output for exchange of infomation with Administrations using manual/mechanical systems will be
30、as simple as possible. 3.1.2 Between Administrations operating computer-based billing and accounting systems, adherence to the standard data record format for data transmission purposes will ensure that simple interface programme will be needed to enable any one computer installation to generate sui
31、table input for, and accept output from, other computer installations. 3.2 Data transfer 3.2.1 Procedures already exist for transfer of data in conventional (printed) form through the mails. Data in encoded form could be transferred by mailing of magnetic or paper tapes, diskettes, paper tape transm
32、ission by telex or data transmission over 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 loss in transit. In addition, there can be difficulties caused by the fragility of paper tape and incompatibili
33、ty of various forms of magnetic tape recording. 3.2.3 Transfer of data via the telex service using paper tape transmission and reception can be advantageous for Administrations whether they have computer-based accounting systems or manuaUmechanica1 systems. As both page copy and punched paper tape c
34、an be generated at the receiving point, users of either type of accounting system can benefit. Page copy can be used for checking paper tape, with the latter becoming input to a computer. Page copy can also be used as the incoming international account avoiding the need for use of the postal service
35、. 3.2.4 Where large volumes of data are to be exchanged, transmission over higher speed circuits offers significant benefits. Where suitable data links are in use for service transmissions, these could be utilized. Data terminals and modems capable of transmission speed in the range 600 to 2400 bits
36、 per second should be sufficient, but higher speeds could be used. For manuaVmechanical systems, data received on data terminals can be reproduced as page copy representing an incoming international account. For computer-based accounting systems, data transmission offers the possibility of complete
37、automation of the process by computer-to-computer transfer. 4 Specific recommendations 4.1 It is recommended that: 4.1.1 encoded form. Where possible data transferred in printed form should be replaced by data transferred in 4.1.2 should be followed. For data transferred in encoded form, the standar
38、d data record format detailed in Annex A 4.1.3 Transmission of data in encoded form should be by the following means: a) physical transfer of magnetic tapes (the standard file structure is given in Annex A); b) physical transfer of diskettes (3% inch/MS DOS); c) use of data transmission over telepho
39、ne circuits, dedicated circuits, telegraph circuits or special data links. 4.1.4 Transmission methods (international packet switching service, electronic mailbox, etc.), operating practices and technical standards should be agreed between the Administrations concerned and should conform to the appro
40、priate ITU-T Recommendations. 2 Recommendation D.91 (07/96) 5 Code maintenance 5.1 The Secretariat of the ITU-T is responsible for maintenance of the table of service codes and the table of facility codes in Appendices A.1 and A.11 to Annex A. 5.2 New codes can be allocated by the authority of the D
41、irector of the ITU-T. Applications should be made through the ITU-T Secretariat who will arrange for the notification of new codes in the Operational Bulletin.
