The World Telecommunications Standardization Assembly 04 (WTSA-04) adopted Resolution 29 on alternative calling procedures on international telecommunication networks. In that Resolution, the sovereign right of each country to regulate its telecommunications, as expressed in the basic instruments of ITU, was reaffirmed. In this regard, each country has the right to authorize, prohibit or regulate call-back practices. National regulatory measures must be respected by other countries within the limits of their own legislation, and the recognized operating agencies (ROAs) and administrations concerned must communicate and collaborate.

To facilitate this collaboration, a draft guideline has been prepared under which ITU is to collect information once a year on the positions adopted by each country in respect of call-back practices within its territory and disseminate the findings by the most effective method. Administrations and ROAs receiving this information must take all necessary steps to prevent call-back practices from being supplied to countries which prohibit them. The TSB has circulated the questionnaire each year since 1996. The results were disseminated by a TSB Circular.

    A Universal International Freephone Number (UIFN) enables an International Freephone Service (IFS) customer to be allocated a unique freephone number(s) that is the same throughout the world.


    The International Premium Rate Service (IPRS) enables an Information Service Provider (ISP) in a country to be assigned one or more Universal International Premium Rate Numbers (UIPRN), which allow IPRS callers to access information and other services provided by the ISP. For these calls, callers are charged at a premium rate. Detailed charging and accounting principles are defined in the D-Series Recommendations. In some cases, callers may need prior subscription to IPRS with the IPRS originating ROA and/or with the ISP.


    An International Shared Cost Number (ISCN) is a unique number assigned to an ROA for its ISCS customer. This number can be dialed in several countries at a rate equivalent to the national call charge in the country of origin. All other service and call-related charges are paid by the ISCS customer.


    The ITU International Network Designator ATM End System Address (ITU IND AESA) is defined by the ITU for use by service providers for the provision of ATM services. The ITU IND AESA enables companies, corporations and governmental institutions to implement an ATM addressing scheme for public ATM services that may or may not be offered accross international borders.

    The IPR ad hoc group met in Geneva, 11-12 March 2005 to discuss IPR matters relevant to standardization in ITU-T.

    The revision of two patent declaration forms was completed the meeting: the General Patent Declaration form and the Patent Declaration form for common & twin texts with ISO/IEC. The updated texts now reflect changes agreed by the group at its July 2004 meeting.

    The group also produced a new version of the Software Copyright Guidelines, whereby the second paragraph in section 2.3.1 was moved to a new paragraph following the section 2.3.

    And in the "marks" front - i.e., trademarks, service marks and certification marks - the group agreed on a first version of Guidelines on how to use "marks" in ITU-T Recommendations.

    The group also discussed on what might define an "Open Standard" from the perspective of standardization work in ITU, and the preliminary outcome was annexed to the meeting report. Even though it does not constitute an ITU-T definition, it may be useful to help progress the discussions elsewhere in ITU.

    Focus Groups are an instrument created by ITU-T that augment the Study Group work programme by providing an alternative working environment for the quick development of specifications in their chosen areas. Focus Groups are now widely used to address industry needs as they emerge, and when they are not covered within an existing Study Group. The key difference between Study Groups and Focus Groups is the freedom that they have to organize and finance themselves. Focus Groups can be created very quickly, are usually short-lived and can choose their own working methods, leadership, financing, and types of deliverables.

    The ITU-T/IEC Common FTP Area was set up within the SG 6 Website as a platform for the exchange of relevant standards documentation between Experts of SG 6, IEC SB4 and TC 46/86 and SC86A/B/C.

    ITU-T Study Group 6 is responsible for studies relating to outside plant of all types of cables for public telecommunications and associated structures. SG 6 considers very important that experts have a commonly accessible platform for sharing relevant standards documentation at an early stage.

    This approach involves people both in IEC and ITU-T, working in the day-to-day development of standards related to cables (copper and optical), their associated hardware and the relevant installation techniques.

    With this in mind the ITU-T Secretariat set up an ITU-T/IEC publicly accessible area, hereafter called the 'Common Area', within the SG 6 Website, as a platform for the exchange of relevant standards documentation. Experts of SG 6, IEC SB4 and TC 46/86 and SC86A/B/C, that are involved in developing standards for products to be installed in the telecommunication Outside Plant, can subscribe for access.

    ITU-T Workshop on NGN in collaboration with IETF

    Where: ITU Headquarters, Geneva
    When: 1 - 2 May 2005


    ITU-T will hold a workshop on NGN together with the Internet Engineering Task Force (IETF), 1 - 2 May, 2005, Geneva. The workshop will also serve as an important meeting point for ITU-T and IETF management.

    The overall objectives of the workshop are to explore specific NGN issues that impact both the ITU-T and the IETF to better understand the work underway in the two organizations and to identify areas where actions could be taken between the ITU-T and IETF to further coordinate their work.

    Six sessions will each be co-chaired by an ITU representative and a representative from IETF. Topics will include requirements and functional architecture; nomadicity and mobility; QoS, control and signalling capabilities; network management; security capabilities and evolution.

    The workshop, the second on NGN in 2005, is an example of the way in which ITU-T is seeking to engage all interested parties in work towards the development of worldwide standards for NGN. In this way, industry demands for the efficient and swift completion of the specifications that will define the way that NGNs work will be met.


    • To explore specific NGN issues that impact both the ITU-T and the IETF to better understand the work underway in the two organizations; and
    • To identify those areas where actions could be taken between the ITU-T and the IETF to further should coordinate their NGN-related work., and to seek to reach agreement on any actions to be taken to coordinate the work of the two organizations and perhaps establish joint activities.

    Advances in the Standard H.264/AVC

    Where: San Diego, California, USA
    When: 31 July ? 4 August 2005

    On the occasion of SPIE?s fiftieth anniversary, ITU-T will lend its support to a session titled Applications of Digital Image Processing XXVIII (Advances and Applications in H.264/AVC Video Coding).

    H.264 / Advanced Video Coding (AVC) is the leading video codec developed jointly by the Joint Video Team of ITU-T Q.6/SG16 VCEG and ISO/IEC MPEG.

    The session will include presentations on recent advances, new directions, new application areas, licensing and IP issues, and the economic impact of the standard.

    H.264/AVC has seen a steady rise in status over the last year, its success based largely on its increased efficiency over its predecessor. The dramatically increased compression performance of H.264 will enable existing applications like videoconferencing, streaming video over the Internet, and digital television on satellite and cable to offer better quality video at lower cost. It will also allow new video applications such as High-Definition TV on DVD, video on mobile phones, and videoconferencing over low bandwidth connections that were previously impractical because of economics or technology.

    H.264/AVC appears certain to be incorporated into several important application specifications including the BD-ROM specification of the Blu-ray Disc Association, the DVB (digital video broadcast) standards for European broadcast television, the HD-DVD specification of the DVD Forum and in a new broadcast TV specification of the US ATSC (advanced television systems committee). H.264 has also been adopted by both 3GPP and 3GPP2, the two partnership projects that define the specifications for third generation mobile.

    And the video codec is now being deployed in products from companies including Apple, Sony, BT, France Telecom, Intel, Motorola, Nokia, Polycom, Samsung, Tandberg and Toshiba.

    2004 also saw the development of a new set of coding tools known as the fidelity range extensions (FRExt). The new FRExt extensions were designed to be used for applications such as standard-definition and high-definition television, enhanced DVD video, content contribution, content distribution, post-production processing, and studio video editing. Additionally a conformance testing specification for H.264/AVC was released. This will allow potential purchasers and manufacturers to ensure that all equipment designed to use the video coding standard will work properly together.

    Fibre-to-the-Premises Standards Showcase

    Where: Chicago, USA
    When: 6 - 9 June 2005

    • Promoting international standardization
    • Demonstrating new/interoperable equipment
    • Featuring High Definition Video (HDV), super-fast internet access and next-generation voice services

    Supercomm, June 6-9, Chicago, USA will see ITU-T members, and guests stage an interoperability showcase for fibre to the premises (FTTP) related standards.

    On show will be passive optical network (PON) equipment built according to the ITU-T G.984 and G.983 series of Recommendations. PON technology is used in the local loop to connect residential and SME end users premises in an all-fibre network.

    With PONs, signals are carried by lasers and sent to their destination without the need for active electronics. Carriers can realize significant savings with fiber sharing in the distribution network, equipment sharing in the Central Office and by eliminating the dependence on expensive active network elements.

    ITU-T Recommendations in the G.984 series detail gigabit PONs (G-PON), the latest generation of PON technology. Increasing capacity to gigabit levels should more than satisfy foreseeable customer demands, offering video applications, high-speed Internet access, multimedia and other high-bandwidth capabilities. G-PON maintains the same optical distribution network, wavelength plan and full-service network design principles of broadband PONs (B-PON) defined in ITU-T Rec G.983. And, as well as allowing for increased network capacity, the new standard offers more efficient IP and Ethernet handling.

    17 vendors will show B-PON interoperability, products for G-PON, optical distribution network, testing and performance and video service equipment and set-top boxes.

    Workshop on IPv6

    Where: Geneva
    When: 22 - 23 June 2005


    ITU-T is hosting a workshop on IPv6 organized in cooperation with the European Union?s IPv6 Task Force Steering Committee (IPv6 EU TF-SC) and the IPv6 Forum.

    Taking place in Geneva, between 22 to 23 June 2005, the event will examine the current status of IPv6, with regards to rollout, policy, technology and applications. An additional aim will be to promote awareness of IPv6 to countries where Internet use is relatively low. The workshop will also follow-up on recent comments sent to the Director of ITU-T?s secretariat, the Telecommunication Standardization Bureau (TSB) on the management and distribution of IP addresses.

    Presentations will come from key standards making organizations, policy advisers and the private sector.


    • Review the current development of Ipv6 network, technology and applications
    • Bring more awareness to those countries who are less-developed in internet to promote the development of IPv6
    • Further discuss comments sent to the Director of TSB concerning the resource management policy.
