New About Us pages have been developed to give those new to ITU-T an overview of the work of the world’s premier ICT standards organization.

The pages offer an overview of ITU-T, a guide to its framework and working methods and high level introductions to each of the Study Groups (eg Study Group 15).

Users are invited to submit questions to an already well populated FAQ and an animated sequence puts ITU standards into a real world context.

Standards development and standards approval procedures are also summarized. A news page contains YouTube highlights and a list of all ITU-T RSS feeds. The contacts page includes an embedded googlemap and should help you find the right person to talk to if you have any enquiries. If all else fails will always help direct your mail.

The second ITU Symposium on ICTs and Climate Change (June 17-18 in London, UK, hosted by BT) will be made available as a live webcast in order that remote participants can see and hear presentations from wherever they are in the world.

The symposium will bring together key specialists in the field, from top decision-makers to engineers, designers, planners, government officials, regulators, standards experts and others. (See here for programme, bios and presentation slides).

Remote participants may also submit questions in real-time to:

NXTComm, June 16-19, Las Vegas, USA will see ITU-T members, and guests stage an interoperability showcase for fibre to the premises (FTTP) related standards.

ITU, together with Telcordia, have collaborated to organize a multi-company interoperability demonstration featuring gigabit passive optical network (G-PON) equipment built according to the ITU-T G.984 series of Recommendations (standards) , including the recently consented G-PON reach extender (ITU-T G.984.6). PON technology is used in the local loop environment to cost effectively connect residential and small and medium enterprises (SME) end users premises in an all-fibre network.

The G-PON Pavilion features live demonstrations of G-PON equipment interoperability; with interoperability being a critical enabler to reducing G-PON equipment costs. Triple-play interoperability demonstrations are provided by the following device and equipment manufactures: Cambridge Industries Group, Freescale Semiconductor, Iamba Network, Ikanos Communications, LS Cable, XAVi Technologies, ZTE Corporation. Corning is providing a bend-insensitive fibre (built to ITU-T G.657 specs) based optical distribution network over which the 2488 Mbps/1244 Mbps (downstream/upstream) G-PON systems will be operating.

With PONs, signals are carried by lasers and sent to their destination without the need for active electronics in the outside plant of the telecommunications network. Carriers can realize significant savings with fiber sharing in the local loop, equipment sharing in the central office and by eliminating the dependence on expensive active network elements.

ITU-T’s G.984series Recommendations detail gigabit PONs (G-PON), the latest generation of PON technology. With gigabit capacity today and the ability to transparently support future capacity upgrades through ITU-T G.984.5 compatible overlays, ITU-T G.984-based systems should more than satisfy foreseeable customer demands. G-PON (ITU-T G.984.6) reach extender solutions allow operation over as much as 60 km of fiber, with split ratios as high as 1x128.

ITU-T NGN expert, Seungyun Lee, from the Korean Electronics and Telecommunications Research Institute (Korea) will make a presentation at the upcoming Telemanagement Forum’s (TMF), Service Delivery Summit. Lee’s presentation is entitled Towards a SOA/WS enabled NGN Open Service Environment - ongoing developments in ITU-T SG13.

His abstract:

“Across the telecom industry, much work is underway to separate the communications capabilities in today’s networks from the networks themselves and to make those capabilities available for integration into the applications in the IT industry. This effort is making possible a rich menu of modular building blocks that can be easily mixed and matched with building blocks from the IT industry to form wholly new kinds of multimedia services and automated business processes that marry the rich content, data applications, and business processes of the IT world with the intelligent, real-time, in-the-network functions of the telecom domain.

Key to this effort at the core of future multimedia service architectures are the SOA (Service Oriented Architecture) and the WS (Web Services) frameworks. ITU-T SG13 has started the development of specifications towards the integration of SOA and WS technical approaches in the NGN context. In line with approved and ongoing ITU-T recommendations, this presentation, building over the basic concept of NGN capabilities, will introduce some key requirements and capabilities for the support of an advanced open service environment in NGN. The integration of SOA and WS in NGN will be then examined, including some achievements and current challenges for the standards community.”

The event focuses on the drive to create an open, industry owned blueprint of how new and exciting services can be created and delivered across complex value chains. It examines standardization of key elements of service delivery platforms (SDPs), which will open up the ability of partners to add end-user value by working seamlessly together to deliver novel services, created and delivered in a fraction of the time and cost it takes today, while dramatically cutting integration costs and avoiding vendor lock-in.

A recent meeting of ITU-T’s Study Group 12 saw consent – first stage of the approval process - on two key new standards for IPTV.

The first ITU-T Recommendation defines user requirements for Quality of Experience (QoE) for IPTV services.

Quality of Experience (QoE) is defined thus: The overall acceptability of an application or service, as perceived subjectively by the end-user.

The new Recommendation (ITU-T Rec. G.1080) defines QoE requirements from an end user perspective, agnostic to network deployment architectures and transport protocols. They are specified as end-to-end and information is provided on how they influence network transport and application layer behaviour. QoE requirements for video, audio, text, graphics, control functions and meta-data are provided.

The second ITU-T Rec. (ITU-T Rec. G.1081) consented defines performance monitoring for IPTV. The goal of this is to provide higher QoS/QoE to customers by identifying, localizing and quantifying service and network issues. IPTV performance monitoring can be software based, hardware based, or a hybrid.

Monitoring parameters, monitoring points and monitoring methods are defined that allow the service provider/network operator to monitor the performance of the service delivery to the end user.

Successful deployment of IPTV services requires performance to be monitored at the customer premise (e.g. set-top-box), key aggregation points such as DSL Access Multiplexer (DSLAM) or cable modem termination system (CMTS) and at interconnect points between disparate network domains. Performance monitoring can help:

  • Find errors in an end-to-end system (system debugging)
  • Check the resource utilization and the work load of system components
  • Compare values (metrics) regarding performance of different system deployments
  • Provide a base for modelling the system
  • Find system bottlenecks
  • Optimize IPTV network deployment
  • Ensure that system performance does not degrade with time.

IPTV standards are progressing rapidly through ITU-T's IPTV Global Standards Initiative (GSI). With successful first generation IPTV services offered by many service providers worldwide standards are seen as vital to boost next generation services where a customer may go into shop, buy an IPTV box, call their network operator and sign-up and then access services from a range of third party service providers. More Recommmendations are expected to be consented at the upcoming IPTV-GSI meeting 23-27 June in Geneva.
