  1. Operation and Numbering Presented by Geng-Sheng LI Email: geng-sheng.li@itu.int Telecommunication Standardization Bureau

  2. Introduction Another aspect of TSB is that it is also responsible for the application of ITU-T Recommendations on Operation and Numbering issues, and to make known these Recommendations to Administrations and Telecom Operators: • Collects and Disseminates Information • Publishes the Operational Bulletin • Maintain an ITU-T website on numbering • Assigns Codes and Numbers • Acts as Registrar for Global Numbers Telecommunication Standardization Bureau

  3. Responsibilities To collect and disseminate information from Administrations/ROAs according to Article 8 of ITR (WATTC-88) and Article No. 202 of the ITU Convention (PP-98); using: • Circular Letters • Questionnaires • Correspondence Telecommunication Standardization Bureau

  4. ITU Operational Bulletin • Operational Bulletin: • Telegram/Telex • Telephone service • Mobile Phones • Data • Changes in Administrations • Maritime Mobile Service • Other information, etc. • Favoured medium for more than 40 years • Issued twice a month (1st and 15th each month) in 3 languages, 24 issues per year. • Contains information about: http://www.itu.int/itu-t/bulletin/index.html Telecommunication Standardization Bureau

  5. Five media to obtain the Bulletin: Printed version (delivered by airmail); Version delivered by fax; Version delivered by E-mail; Electronic version accessible online; Electronic version of single issue via ITU electronic bookshop Subscription to ITU Operational Bulletin Telecommunication Standardization Bureau

  6. The yearly subscription fee (24 issues, included annexes): Catalogue price: 385 CHF Member Stats and Sector Member: 330 CHF Least developed countries: 77 CHF Subscription fee of ITU Operational Bulletin Telecommunication Standardization Bureau

  7. ITU Circular Telegrams … were used for important or urgent communications to Member States. Now replaced by other means, such as Facsimile etc. Telecommunication Standardization Bureau

  8. ITU-T Website (1) A homepage has been created for ITU Operational Bulletin: www.itu.int/itu-t/bulletin/index.html It includes: • ITU Operational Bulletin • Lists annexed to the ITU Operational Bulletin • How to order ITU Operational Bulletin – Publication Notice Telecommunication Standardization Bureau

  9. ITU-T Website (2) • A homepage has also been created http://www.itu.int/itu-t/inr/nnp/ which assembles information on National Numbering Plans for all countries • Administrations are requested to provide either a link to their numbering Websites or the text to be posted on TSB Website • New Rec. E.129 gives some examples of how the format of the numbering plan should be presented • A Notification Service is also available to notify you of any changes as they occur Telecommunication Standardization Bureau

  10. Telephone Service ITU-T Recommendation E. 164 Assigned country codes List of E.164 Country Codes annexed to O.B. No. 763 (1.V.2002) • Geographical country code • Network country code • Group of countries • Trial country code • Global Services country code Telecommunication Standardization Bureau

  11. Telephone Service For example: • Geographical country code: Botswana = +267 • Network country code: Global International ATM network (Telekom Malaysia) Network = +882 31 • Group of countries: European Telephony Numbering Space = +388 3 • Trial country code: Neustar for ENUM trial = +991 001 • Global Services country code: Universal International Freephone Number = +800 Telecommunication Standardization Bureau

  12. Notification of National Numbering Changes: ITU-T Recommendation E.164, paragraph 7.4.2 asks Administrations: to advise TSB of NNP changes 2 years in advance to use the 0 as national prefix to use 00 as international prefix To have a maximum of 15 digits Telephone Service Telecommunication Standardization Bureau

  13. Notation of national and international telephone numbers, etc. See ITU-T Recommendation E.123 Symbols to be used in letter heads or business cards e.g. Tel: +267 65 0300 Fax: +267 35 7976 Mobile: E-mail: Web: Telephone Service Telecommunication Standardization Bureau

  14. List of Various tones used in national networks annexed to O.B. No. 665 (1.IV.1998) (Rec. E.180 and E.182) Dial Tone Ringing Tone Busy Tone Congestion Tone Special Information Tone Call waiting Tone Pay Tone Telephone Service Telecommunication Standardization Bureau

  16. List of Dialling Procedures Annexed to O.B. No. 759 (1.III.2002) Country Codes Prefixes National (significant) numbers Telephone Service Telecommunication Standardization Bureau

  17. Issuer Identifier Numbers (IIN) • See ITU-T Recommendation E.118 - Based on ISO-7812 • TSB acts as Registrar, List of IIN annexed to O.B. No.757 (1.II.2002) • Used for Subscriber Identification Module (SIM) cards. Format = 89 + E.164 country code + two or three digits, e.g. Botswana: 89 267 01 • A single IIN is assigned to Card Issuers from the ITU’s block of “89” Telecommunication Standardization Bureau

  18. Signalling Area Network Code (SANC) • International Signalling Point Code (ISPC) is used to identify a signalling point within international signalling system No.7 network • ISPC = 14-bit binary code • SANC = combination of NML and K-D • CBA identifies a specific signalling point which, when combined with SANC, = 14-bit ISPC • Administrations responsible for allocation of ISPCs: Rec. Q.708 Telecommunication Standardization Bureau

  19. SANC/ISPC List of SANC annexed to O.B. No. 767 (1.VII.2002) List of ISPC annexed to O.B. No.761 (1.IV.2002) Botswana: 6-104 Zambia: 6-090-0 (Lusaka Gateway) Telecommunication Standardization Bureau
