3 The Evolution of DSL Deployment High speed Internet access is the foundation upon which broadband networks are built, but it takes more than access to attract and retain new customers. Service providers need an access management platform that enables advanced revenue-generating services for business and residential customers, protects existing investments, and provides guaranteed bandwidth. With its multiple classes of digital subscriber line (DSL) service, interoperability with legacy equipment, multiple ATM QoS capabilities, and IP functionality, the Alcatel 7300 ASAM is the answer for DSL deployment. With the largest installed base of DSLAMs in the world, Alcatel designed the new, low profile Alcatel 7300 ASAM LP to seamlessly integrate with these systems and with the 70 million lines currently being served by Alcatel or third party digital loop carriers (DLCs). As DSL proliferation continues in the central office (CO), service providers will need to focus on remote deployment of DSL to ensure continued success. The Alcatel 7300 ASAM LP accomplishes this by integrating into the existing network infrastructure. Service providers can mix the Alcatel 7300 ASAM LP shelves with legacy shelves in the field to create a single system that delivers enhanced functionality while preserving past investments in voice infrastructure. Beyond hardware interconnectivity and software consistency, the systems also share a single management system, simplifying the integration of the Alcatel 7300 ASAM LP into the DSL network. Feature Summary The Alcatel 7300 ASAM LP helps to leverage existing infrastructure by installing easily into existing DLC cabinets. It is a proven adjunct solution as a DLC overlay. This highly deployable platform offers a port density of up to 24 lines per card. The Alcatel 7300 ASAM LP scales to 5,000 lines per network interface. Its power consumption of 1.6 watts per line is the lowest in the market. The Alcatel 7300 ASAM LP features a wide variety of interfaces. They include DSL interfaces (asymmetric DSL (ADSL), G.lite, G.shdsl), network interfaces (DS3, OC-3), and subtending interfaces (DS1, inverse multiplexing over ATM (IMA), DS3, OC-3). 1

4 The advanced features of the Alcatel 7300 ASAM LP include support of virtual circuit (VC) aggregation, switched virtual circuits (SVCs), IP multicast, virtual private networks (VPNs), multiprotocol label switching (MPLS), and multiple levels of ATM QoS, including unspecified bit rate (UBR), constant bit rate (CBR), variable bit rate VBR), and guaranteed frame rate (GFR). The Alcatel 7300 ASAM LP is a true carrier class device, offering integrated test access and redundancy. It can operate in extreme temperatures and is listed with Underwriters Laboratories (UL). Architecture The Alcatel 7300 ASAM family can contain as few as 12 DSL lines, or as many as 2,592 lines sharing a common network interface. This number can go up to 10,000 by subtending shelves. An Alcatel 7300 ASAM can manage the Alcatel 1000 Remote Access Multiplexer (RAM), the Alcatel 7300 DSL Remote Access Platform (RAM), the Alcatel 1000 ASAM Mini-Remote Access Multiplexer (M-RAM), and the Alcatel 7300 ASAM LP. This extends the reach and capabilities of DSL to remote customers and increases the number of customers served by a single network interface. A broad range of network and subtending interfaces are available. The Alcatel 7300 ASAM LP, designed primarily for remote deployment, provides service for 144 lines per shelf and 288 lines per adjunct cabinet. One rack can contain 432 lines for central office or controlled environment vault deployment as well. With the ability to provide ADSL, full rate SHDSL, IP-multicast, VPN, and aggregation, 100 percent DSL penetration is possible with a complete service portfolio. The full range of QoS for delivery of business services, video, and voice over DSL (VoDSL) make the Alcatel 7300 ASAM LP a full service remote solution. Including other DLCs into the adjunct local connection saves on facilities costs, and the standards-based architecture of the ASAM family helps achieve service ubiquity with the existing DSL network. The integration of the Alcatel 7300 ASAM LP into existing ASAM networks requires no new methods, procedures, or equipment practices. 2

5 Expanding the Power of the Access Platform The IP Services Module (ISM) is the first of this line of products to offer IP and broadband remote access server (BRAS) functions and features, like IP multicast, VC aggregation, and local Ethernet connectivity in the access network. The ISM is a two-slot line termination card that slides into the front of the Alcatel 7300 ASAM. The ISM enables video multicast services with Internet group management protocol (IGMP) at the edge. This significantly increases delivery capabilities and reduces network congestion. The growth of broadband services like video is driving the requirement for more intelligent IP-based devices that provide differentiated access services. As more ADSL technology is deployed, scalability and efficiency become critical issues. The ISM is a multiservice access concentrator platform based on the Alcatel 7404 Broadband Access Server (BAS). It provides termination of ATM encapsulation, session management, and IP layer filtering and forwarding. The adapter optimizes provisioning and network management with VC aggregation while it opens Ethernet connectivity to the Alcatel 7300 ASAM LP, providing open access to both ATM and IP networks for distributed content servers. 3

6 Troubleshooting DSL deployments can require in-depth troubleshooting. If subscriber loops are too long, they may be unsuitable for DSL service. Load coils, bridge taps, or wideband noise on the line can cripple DSL service performance. Diagnosing such problems may require costly truck deployments and the expertise of senior technicians. This may result in delays of several weeks, dissatisfied customers, lost revenues, and higher operational costs. To overcome these issues, service providers need a streamlined deployment process. Alcatel s integrated test access capabilities provide visibility of the entire network before lines are put in service. This allows line qualification without false positive or false negative results. Better tools can help providers qualify, test, and troubleshoot DSL services more efficiently. Tools that can be used proactively help service providers to identify potential customers and eligible services and to pinpoint problems early. As a result, installations proceed smoothly and quickly, with minimal deployment delays and lower operating costs. Unsurpassed QoS The Alcatel 7300 ASAM LP supports permanent virtual circuit (PVC) connections provisioned by network operators, and SVC connections set up and managed by the user application when needed. Users gain greater flexibility in accessing multiple applications offered by various content providers. Network operators gain traffic capacity and simplified provisioning. The Alcatel 7300 ASAM LP is built around an ATM architecture that supports a variety of ATM service classes including CBR, UBR and UBR+, real time and non real-time variable bit rate (rt-vbr and nrt-vbr), and GFR. This gives service providers exceptional flexibility in service offerings. These offerings can range from low cost, low priority residential services to premium business access with large bandwidth requirements, such as LAN-to-LAN, VPNs, streaming video, and audio. All of these service offerings have guaranteed performance. Reach All Potential Subscribers In a fast growing mass market like DSL, the first provider to the customer wins. The Alcatel 7300 ASAM and Alcatel 7300 ASAM LP deliver maximum scalability for small to large system deployments that allow service providers to reach more of their potential DSL customers, whether they are served by a CO or by remote facilities. The operator can quickly achieve broad geographic coverage with small systems, and extend the capacity of these systems at the pace of growing customer demand. The system is temperature hardened so it can be reliably deployed in extreme temperature environments or in office buildings. These capabilities, along with the multiple DSL types, mean that service providers can service more customers and have more flexibility to meet their demands. 4

It shows the host Alcatel 7300 ASAM acting both as a local DSLAM serving customers directly connected to the CO, and as an aggregation and service node for remote ASAMs that include already installed RAMs and mini-rams, and new Alcatel 7300 ASAM LP deployments. Summary The Alcatel 7300 ASAM LP is the next step in the evolution of DSL deployment. With its flexible interfaces, ease of deployment, carrier class service capabilities, and advanced networking features it meets the many challenges of DSL networking today and for the future.
