ITU-T SERIE H SUPP 3 FRENCH-2003全方位服務超高速數字用戶線路(VDSL)在ITU-T建議h.610和h.611操作要求

ITU-T Recs H.610 and H.611 define the architecture and operations, administration monitoring and provisioning (OAMP) requirements for the delivery of video, data and voice services across a VDSL access network to an in-home environment, known as a Full-Service VDSL (FS-VDSL)network.This Supplement provides the operator requirements for services and infrastructure deployment upon which these Recommendations were based. The intent was to maximize commonality of the operators' requirements to help vendors to implement common products, which can then be offered in all international markets thereby achieving economies of scale.The Recommendations aim to enable the provisioning of a bundle of triple-play services in a reliable way, with minimal user intervention, respecting the key requirements of security and conditional access to the content and at a cost compatible with mass market deployment. Only the elements that need to be specified to achieve an interoperable low-cost platform are included in these specifications. It is intended that each service provider can define and evolve a distinct portfolio of competitive services using the 'bricks' defined in the Recommendations with downloadable software configuration.VDSL is referenced throughout the Supplement as the physical layer technology; however, the architectural specifications contained herein could be equally applicable to CPE and Access Networks employing other broadband physical layer technologies.
