Application Fact Sheet Freescale Semiconductor, Inc. ACCESS Freescale Semiconductor, Inc... MULTISERVICE DSLAM KEY BENEFITS • Simplified universal line card design for multiple DSLAM line card instantiations, delivering cost efficiencies and faster development • High density aggregation of subscriber line xDSL ports – from 32 xDSLs to 128 xDSLs – using a single C-3e NP, and even higher density with a C-5e NP • Wide range of networking uplink card interfaces and speeds including GbE, OC-3c, OC-12c, and OC-48c with a supporting library of DSLAM-oriented reference software applications OVERVIEW Digital Subscriber Line Access Multiplexers (DSLAMs) are a leading broadband access technology, delivering exceptionally high-speed data transmission over existing copper telephone lines. In the process, they are transforming the existing public network to a highperformance, multiservice network. DSLAMs support a wide variety of high-bandwidth applications including voice on demand, high-speed Internet access, and streaming multimedia content. Next-generation DSLAM platforms will offer greater density and lower cost per port along with more diversity in services (such as voice gateways and virtual private networks) using multiple DSL transports such as ADSL, VDSL, HDSL, SHDSL, and so on. Motorola offers a family of integrated network processors and software that addresses these specific DSLAM requirements, along with high density and scalability, enabling the development of high-performance, multiservice DSLAMs. DESIGN CHALLENGES Typical DSLAM systems are ATM based with the primary role of aggregating multiple xDSLs for uplink to the network. The number of subscribers a DSLAM can handle is a key requirement and supporting such high density per platform or card requires a range of interfaces and speeds. On the networking uplink services side, where ATM is prevalent, IP routing is gaining quickly while some systems require support for Frame Relay and TDM traffic. Consequently, any solution must to be able to handle the diversity and interworking of networking technologies such as IP-to-ATM switching and Segmentation and Reassembly (SARing). The trend toward value-added services such as Quality of Service (QoS) capabilities, VPN gateways, and media gateways necessitates a total system approach leveraging a universal line card strategy where software reuse and reuse of previous line card designs can lower overall development costs and bring your product to market faster. • Supports queuing, shaping, and policing for individual ATM and IP flows for each ADSL line, supporting ATM Traffic Management 4.1, IP DiffServ, IntServ and MPLS QoS Today’s DSL network places demands on a DSLAM system to support high DSL line density for ATM and IP traffic while providing QoS guarantees and other services to individual users • Broad range of DSLAM value-added services, such as advanced QoS and VPN security, available from Motorola and its Alliances For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc. Freescale Semiconductor, Inc... Motorola is your single source for comprehensive, embedded solutions for DSLAM architectures — providing network processing, host processing, and traffic management technologies Bottom line: a DSLAM design must combine the best of density, speed, functionality, scalability, and cost efficiency. Additional design challenges include the need for: • Backhaul services for packet, cell and circuit-based applications through concentration of high density DSL lines onto 10/100 Base-T, T1/E1, T3/E3 and ATM outputs (OC-3/12/48), and scalability so that uplink capacity can be appropriately matched with future demand. • Inherent multiservice capabilities for ATM, Frame Relay, IP and TDM on a single platform using multiple DSL transports such as ADSL, SDSL, RADSL and G.SHDSL. • A full suite of QoS service performance guarantees in order to manage the rising demand of new services, network models, and applications, such as packetized voice and video. • Temperature ‘hardened’ devices for installation in areas that are not environmentally controlled (such as remote terminals or curbside cabinets) and adhering to network equipment building standards (NEBS). MOTOROLA® SOLUTION Motorola offers a complete line of communications processors and reference software for solving your DSLAM design challenges. Motorola’s communications processors include the C-Port family of network processors (C-3e NP and C-5e NP), traffic management coprocessors (TMCs), and interface adapters. Plus you can leverage Motorola’s host processors (PowerPC®) and security processors (MPC185 and MPC190) as needed by your design. In addition, you can use Motorola’s library of reference software for the C-Port family (called C-Ware Applications Library) that provides data plane code that can be mixed and matched to best address your DSLAM line card requirements for both subscriber line cards, up link cards, and even combinations thereof. The C-3e NP handles high-density DSL aggregation ranging from 32 to 64 to 196 lines (with an external Utopia 2 interface adapter) or greater densities with the C-5e NPs. The C-Port TMCs provide queuing, shaping, and policing for individual ATM and IP flows for each ADSL line. This ensures that delay-sensitive traffic traversing over congested networks can do so in a timely fashion. The TMCs support ATM Traffic Management 4.1, IP DiffServ, IntServ, and MPLS QoS. These features enhance a DSLAM vendor’s ability to support new, value-added, revenue generating services for applications requiring guaranteed classes of services, such as voice on demand, video conferencing, and multimedia streaming, all across xDSL lines. C-Port network processors are well suited for uplink card applications, able to handle a range of network interfaces and speeds, from sub T1, T1/E1, OC-3, OC-12, and up to OC-48c. C-Port NPs also enable the interworking of multiple network services including AAL-5 and AAL-2. C-Port NPs come integrated with a high degree of functionality including queuing and classification coprocessing, and SMS flow accounting capabilities, critical for the management and billing of DSLAM services. As your product functionality evolves, the C-Port NPs can be easily reprogrammed to address new requirements because C-Port NPs are programmed in C-language using Applications Programming Interfaces (APIs).
