NXTComm, June 18-21, Chicago 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 Recommendation. 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: Alphion, Cambridge Industries Group, Hitachi, Huawei, iamba Networks, LS Cable, PMC-Sierra, Tellabs, Terawave Communications, TXP Corporation, XAVi Technologies, ZTE Corporation. Corning is providing the optical distribution network components 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 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. As well as allowing for increased network capacity, the new standard offers more efficient IP and Ethernet handling.

ITU and the IEEE will hold a workshop on carrier-class Ethernet, 31 May - 1 June.Much work has been done in both organisations to progress Ethernet, developed as an enterprise technology, into a carrier service. The event will focus on opportunities for further collaboration. Long-recognized as the ubiquitous LAN technology, Ethernet is now seeing increased attention as a carrier-grade service. In part this is due to the convenience of being able to simply provide end-to-end service, but also carriers can realize savings both in terms of capital and operational expenditure.

Ethernet services are becoming popular because they allow carriers to offer considerably improved flexibility to customers through a much simpler and lower cost interface. Ethernet allows users to specify exactly how much bandwidth they want between the 10Mbit/s and 1Gbit/s range currently offered. Further, Ethernet provides reduced operation complexity and improved scalability for carriers. And as operators look to NGN and the use of the Internet Protocol (IP), Ethernet is seen as the best fit, especially given the rise of such services as IP VPNs, VLANs and dedicated Internet access.

The event will start with an overview of the standards work from ITU-T and IEEE and will then drill down into detail with sessions focusing on: Ethernet based and Ethernet capable access networks; Ethernet network transport; Ethernet Bridging architecture; Ethernet OAM and management; Ethernet QoS, timing and synchronization. A closing session will bring together reports from all of the session chairs in order to identify the direction of future work.

Following up on advice from ITU-T Study Group 2 (see previous story), the Director of TSB has assigned E.164 country code 888 to the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) for the purpose of facilitating the provision of an international system of naming and addressing for terminals involved in disaster relief activities in an area of a country that has been cut off from the national telecommunications system of that country.

This separate, alternate naming and addressing system will continue in operation until such time as normal telecommunications can be restored and the disaster location is once more part of the national telecommunications infrastructure. The use of any numbering resource will therefore be relatively short lived and the resource may be re-used at a later date for another location.

Subsequent digits of the codes (for example, identification codes under the E.164 code) will be allocated and administered by OCHA.

The numbering resources are assigned solely for the use of UN emergency responders and not for other purposes. The commercial aspects of the use of the numbering resource will be negotiated between OCHA and the appropriate operators and service providers. In addition, the Mobile Network Code (MNC) 88 under the E.212 shared Mobile Country Code 901 has been assigned to OCHA for the same purposes.

Study Group 11 meeting in Geneva, end April has consented three important documents charting protocols for quality of service (QoS) in NGN. The protocols will ensure interoperability between network elements and systems as well as giving service providers the ability to specify rules for specific communication types.

The announcement marks a significant step forward for ITU-Ts NGN work. Protocol development is seen as the final stage of standards development following identification of the requirements, architecture, services etc. The Recommendations are a crucial part of the NGN standards package and a concrete realization of the functional architecture defined in ITU-T Rec. Y.2111 - Resource and admission control functions in Next Generation Networks.

The protocols agreed at the April meeting will guarantee that when a service request is made QoS needs are transmitted, ensuring that each network element provisions the correct level of bandwith and resources to ensure the class of QoS for that particular application. So for example more bandwidth can be allocated and guaranteed for IPTV than for voice.

The three ITU-T Recommendations include the specification of the physical entities involved in resource control signalling, the interfaces across which signalling takes place, and the mapping between these entities and interfaces and the corresponding functional entities and reference points in ITU-T Rec. Y.2111. An Appendix provides a further mapping between the interfaces and the protocol specifications which realize those interfaces.

The Recommendations refer to signalling used in different geographical parts of the world: ITU-T Recommendation H.248/Megaco used in for example Japan, COPS used for example in China and Diameter which is used in North America.

Another three protocols in the field of resource control were consented by Study Group 11 earlier in the year.
