H.610 (07/2003) i ITU-T Recommendation H.610 Full service VDSL System architecture and customer premises equipment Summary This Recommendation specifies the system architecture (SA) and customer premises equipment (CPE) architecture for the delivery of video, data and voice services
7、 across a VDSL access network to an in-home environment, known as a Full Service VDSL network. This Recommendation specifies the SA and CPE architecture at a high level, independent of the underlying broadband physical layer transport mechanism. VDSL is referenced throughout this Recommendation as t
8、he physical layer technology; however, the architectural specifications contained herein could be equally applicable to CPE and Access Networks employing other broadband physical layer technologies. This Recommendation defines an architecture that enables the provisioning of a bundle of triple-play
9、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. Source ITU-T Recommendation H.610 was approved on 14 July 2003 by ITU-T Study Group 16 (2001-2004) under
10、 the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. H.610 (07/2003) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is
11、responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by
12、the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collab
13、orative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certai
14、n mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requiremen
15、ts. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. IT
16、U takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual
17、property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2004 All rights reserved.

44、Definitions This Recommendation defines the following terms: 3.1 Access Network (AN): Includes the ONU and the OLT. In the reference model, this is between the U-R2 and the V reference points. The term AN is used to describe the overall capabilities of both the OLT and the ONU. For example, if an at
45、tribute x should be supported by the Access Network, then either the OLT, the ONU or both should implement attribute x. Whenever a requirement addresses a specific network component, it is stated so. 3.2 access network operator: The AN Operator operates the physical access system. Encompassing the d
46、omain between the U-R and V reference point of the system reference model (see clause 6). 3.3 content provider: The Content Provider generates content such as video copies in various digital or analogue formats. The Service Provider is expected to contract the Content Provider in order to have acces
47、s to its content and to allow access to subscribed users. 3.4 core network operator: The Core Network Operator maintains and manages the core network beyond the V reference point and the OLT physical interface. 3.5 digital broadcast network: A multicast Network that is used to distribute point to mu
48、lti-point traffic such as digital TV and radio. 3.6 Element Management System (EMS): The system allowing the AN management. 3.7 Functional Processing (FP): A point of signal transformation or processing. 3.8 Functional Processing and Decoding (FPD): A point of application layer processing of video,
49、audio or data. 3.9 interactive A/V network: A unicast network used to deliver point-to-point video and audio services such as VoD. 3.10 internet network: Broadband data Network in duplex mode for IP based services, typically Internet services. 4 ITU-T Rec. H.610 (07/2003) 3.11 InterWorking to Core Network (IWCN): Any function that may be included in the OLT to interwork with non-ATM core networks. Due to the variety of core network technologies and configuration
