ITU-T Recommendation M.3343 consented at the Beijing meeting of Study Group 4 outlines the requirements and protocol neutral information model necessary to communicate trouble tickets in a multi-service provider NGN environment.

NGN according to the Recommendation introduces new reporting needs to address new service types expected.

The Recommendation describes a trouble in a communications network as a problem that has an adverse effect on the quality of service perceived by network users. Management of trouble tickets is necessary to ensure that they receive attention and that the trouble is cleared to restore the service.

At the time of a trouble, a network may have been inter-working with another network to provide a service. Therefore a standardized way of exchanging trouble management information between management systems across interfaces is necessary.

Study Group 4 saw the consent of a Recommendation (M.3342) which provides the means to document service level agreements (SLA) between a service customer and a service provider.

The Rec. takes into account the fact that NGN demands QoS guarantees for services. SLAs are considered an effective way of solving the problems of QoS guarantee between customers and providers. The Recommendation describes the detailed classification of SLA content, provides guidelines and instructions for the definition and composition of ‘SLA representation templates’ in order to manage QoS and service guarantees more effectively. It also includes instructions on how to complete the templates.

The NGN Management Focus Group (NGNMFG) is seeking more input from service providers and network operators in order to build a more accurate roadmap of needs and existing specifications for NGN management. The group presenting version 2 of its roadmap at the May meeting of Study Group 4, in Beijing, changed its terms of reference to reflect the need.

While roadmap V1 identified NGN management specifications from ITU-T as well as other standards making organizations, V2 provides gap analysis and pinpoints areas that can benefit from better harmonization. Recognizing a gap in managing new functions tying the NGN transport stratum to the service stratum, V2 sees the addition of management of IMS (IP multimedia subsystem) and NGN transport technologies like ASON (automatic switched optical network) and Ethernet.

The roadmap can be found here.

ITU-T together with the Independent Joint Photographic Expert Group (IJG) is celebrating the twentieth anniversary of the formation of the CCITT/ITU-T and ISO Joint Photographic Expert Group (JPEG) with the release of an alpha version of software for a new more efficient compression scheme. The new ITU extension to JPEG known as ITU-T Recommendation T.851 means that compression is increased such that images will take-up less space on people’s hard drives or digital cameras.

The program available here allows users to input image files for compression at a more efficient rate than that currently offered. The group responsible for producing the open source software is inviting people to test and contribute to the development of the project.

Recently, and capitalizing on the ‘toolbox’ concept of the original JPEG design, ITU-T approved ITU-T Rec. T.851, a royalty-free extension that adds to T.81, more commonly known as JPEG, an alternative compression method using so-called Q15 arithmetic coding. Q15 provides not only higher compression ratios for stored and transmitted images, but - compared to the original arithmetic coding in JPEG - also lower latency for compressing and displaying images. T.851 also extends the color precision of JPEG to maximum 16 bits per color component, which is seen as essential in applications such as medical imaging, professional photography and high quality printing.

Founded in 1986 by its parent bodies, the then ITU CCITT Study Group VIII and the ISO/TC97/SC2/WG8 group, JPEG continues today under the auspices of ISO/IEC JTC1 SC29/WG1 and ITU-T Study Group 16. The most famous product of JPEG was ITU-T Recommendation T.81 | ISO/IEC 10918-1, which specifies a process for digital compression and coding of continuous-tone still images, and is more commonly known by the name of the group, JPEG. This is the most used format for storing and transmitting photographs on the Internet, in digital photography and in many other image compression applications, and it was approved in 1992 first by ITU-T (then CCITT) and later by ISO/IEC.

Work on the new compression algorithm was started in 2004 by ITU-T Study Group 16. The aim was to allow users to take advantage of recent technological advances, with the addition to the JPEG suite of an alternative, royalty free coder that would allow even better image compression efficiency and lower latency. The successful completion of this first phase of the work resulted in the publication of the specification ITU-T Rec. T.851 after approval in September 2005. Experts from SG 16 say to stay tuned for further developments.

ITU-T is hosting a workshop NGN and Grids in collaboration with the Global Grid Forum (GGF) in Geneva, 23-24 October 2006.

ITU-T’s Global Standards Initiative on Next Generation Network (NGN-GSI) is well under way and is responding to urgent market needs for global NGN standards. NGN offers increased quality and service features for users, independent of the underlying transport technology.

Grids have been widely used in the scientific community. Increasingly, Grids are being deployed within commercial settings. The Global Grid Forum is actively reaching out to communities such as the Telco community to advance Grid adoption, interoperability and scalability. Different scenarios for Telcos can be envisioned: Telcos may 1) specialize in network SLAs that are optimally suited to Grids; 2) use Grids for their IT internal needs; and/or 3) offer Grids as a managed service to customers.

Study Group 16 has published an ‘Accessibility Checklist’ for the makers of standards to ensure that they are taking into account the needs of those to whom accessibility to ICTs are restricted, the deaf or hard-of-hearing for example. Experts say that such a list will help to ensure that accessibility needs are taken into account at an early stage, rather than ‘retrofitted’. The list will be published on a new webpage acting as a repository for accessibility in standards information.

Study Group 16’s standardization work in the field of accessibility aims to ensure that all sectors of the global community have equal access to communications and online information. This effort goes back to the 1990s with V.18 (an ITU-T Recommendation on a multi-function text telephone).

The work takes into account the fact that users of ICTs have a varied capability for handling information and the controls for its presentation. The source of this variation lies in cultural and educational backgrounds as well as in age-related functional limitations, in disabilities, and in other natural causes. Everyone can benefit from this accessibility standardization work as anyone can be permanently or temporarily disabled due to physical, environmental (e.g. a phone call in a noisy environment) or cultural (e.g. spoken language diversity) conditions. Moreover, we will all grow old and lose facilities that we take for granted now, thus enlarging the part of the population that benefits from accessible communication.

The most important goal of ITU-T’s accessibility activity is to make sure that newly developed standards contain the necessary elements to make services and features usable for as broad a range of people as possible. Standards describe how equipment should interact and what quality is necessary for media to be usable for all, additionally suitable methods of media delivery for people with disabilities are described.

Users of telecommunications and information technology have a varied capability of handling information and the controls for its presentation. The source of this variation lies in cultural and educational backgrounds as well as on age-related functional limitations, in disabilities, and in other natural causes. ITU-T SG 16 effort in accessibility standardization promotes the concept of Total Conversation and aims at ensuring that newly developed standards contain the necessary elements to make services and features usable for people with a range of capabilities as broad as possible.
