    Bulk Data Collection
    		 This Working Text presents an IPDR-based mechanism that allows Service Providers to efficiently collect a potentially large amount of data from their entire CPE population on a regular basis. This bulk data collection mechanism is built upon the IPDR standard as defined in TMForum, instead of the CWMP standard as defined in TR-069, as CWMP is designed to be a device management protocol instead of data collection protocol. So, by utilizing IPDR instead of CWMP the management plane is not polluted and the transfer of the data is more efficient. Devices supporting the IPDR-based bulk data collection mechanism will have the mechanism configured via CWMP.

    • WT# TITLE ABSTRACT
    WT-134
    Policy Control Framework
    		 An architectural framework for policy control of wireline Broadband networks.
    WT-145
    Multi-service Broadband Network Functional Modules and Architecture
    		 This working text provides reference architectures for multi-service broadband networks, defines high level network requirements, and specifies functional modules to meet those networks requirements. This WT also provides guidance to distribute these functional modules onto multi-service broadband network elements. Detailed broadband network nodal requirements will be specified in further working texts e.g. WT-178.
    WT-146
    Internet Protocol (IP) Sessions
    		 Numerous members of the service provider community have recently shown significant interest in migrating from a pure PPP access environment towards one with IP subscriber sessions for delivery of all IP services such as voice, video and high speed internet over a common data transport protocol. A number of factors are driving the interest for such a transition. For one, operators see a potential in simplifying their operational/user support complexity, as well as harmonizing network element functionality around the IP protocol. Operators running multiple access networks also view IP service delivery as the key lowest common denominator towards delivering common services in a converged network, where the PPP would be specific only to PSTN dial and DSL access segments. Given these motivations, the ability to transition to an IP user service delivery model suggests the adoption of a subscriber IP session construct in order to allow the service provider to handle each subscriber according to their individual service contract. This document provides the description of the construct and relevant IP node requirements.
    WT-178
    Multi-service Broadband Network Architecture and Nodal Requirements
    		 Building on TR-144 and WT-145, WT-178 documents a set of architectures for broadband multi-service network, addressing typical infrastructures, topologies and deployment scenarios, and specifies associated nodal requirements.
    WT-203
    Interworking between Next Generation Fixed and 3GPP Wireless Access
    		 Since the introduction of IP enabled mobile devices the overlap of wireless and wireline technologies has emerged. As the widespread growth of mobile devices continues to increase at an enormous rate and become more ubiquitous, their services offered become transparent between both fixed and wireless access networks. Fixed Mobile Convergence is a technology trend impacting almost all telecommunication and Information industries providing the subscribers access to services anywhere anytime regardless of the Access network type they are connected to and providing the Service Providers with the flexibility to ensure transparency of services to the end user.
    WT-207
    Layer 2 Control Mechanism for Broadband Multi-service Architectures Part II

    IPv6 Transition Mechanisms for Broadband Networks
    		 The WT presents an integrated view of transitioning the network from IPv4 to IPv6 operation. As such it documents strategies for dealing with transitional phases with dual stack v4/v6 being considered the interim target, and the eventual sunsetting of IPv4 as the ultimate goal. The WT will document strategies to deal with inconsistent deployment of dual stack, and strategies for dealing with IPv4 address space exhaustion.

    DSL Quality Suite
    		 In the light of Broadband as tomorrow's universal means for communications and a multitude of other services, it is an unavoidable need to tackle the issue of DSL stability and quality by means of advanced and efficient techniques. As the penetration of broadband increases and the related service offers become more and more structured, such techniques represents a tool (or tools) of utmost importance. This is to guarantee overall service quality and performance to customers as well as consolidate broadband as a main service-enabling network platform for Service Providers.

    This Working Text contains the framework for a DSL Quality Suite (DQS) intended as a collection of Broadband Forum documents focused on the management of the quality and stability of DSL lines.

    WT-197
    DQS: DSL Quality Management Tecniques & Nomenclature
    		 A number of different schemes and acronyms can be found in the literature (e.g. DSM Level x, DLM, etc.) for defining the techniques and strategies for monitoring and assuring DSL line stability and quality. Sometimes these names and conceptual approaches are also used by commercial products or within the operational work-flows of access networks. To ease the definition of any further WT under the DSL Quality Suite, the concept of DSL Quality Management (DQM) is introduced as the abstract capability of proactive and efficient control of the quality, stability and efficient exploitation of broadband lines.
    WT-198
    Issue 2
    DQS: DQM systems functional architecture and requirements.
    		 WT-198i2 is a component of the DQS (DSL Quality Suite) which is an ongoing initiative of the Broadband Forum to identify the building blocks (reference features and tools, equipment and system requirements, network strategies and practices) to be used by manufacturers and Service Providers to develop solutions that enable pro-active and efficient maintenance of broadband lines and services.

    DSL Quality Management (DQM) encompasses a range of techniques that seek to monitor, analyse and improve performance and/or stability of a DSL line or a group of DSL lines.

    WT-205
