CABLE MODEM TERMINATION SYSTEM (CMTS)
SG2122/D,
BENEFITS
Single platform architecture DOCSIS, Ethernet, SONET, other interface types
OVERVIEW
hybrid fiber/coax (HFC) network moving from simply providing television programming serving multimedia, broadband network both consumer business data access. Cable multiple system operators (MSOs) well positioned provide both businesses homes with unified gateway supporting data, Voice over (VoIP), streaming video/audio that goes well beyond simple cable modem deployment. This growth will drive demand cable modem termination systems (CMTSs) that provide connectivity, basic routing/switching protocol data units (PDUs), protocol conversion, traffic management, other services.

DESIGN CHALLENGES
CMTS equipment vendors under tremendous pressure support expanded level functionality while adapting evolving standards application requirements. CMTS serves backbone network, bridging interfaces with RF-based cable modems typically built around Data Over Cable Service Interface Specification (DOCSIS®)/EuroDOCSIS. evolution DOCSIS standards added Quality Service (QoS) functionality order support real-time applications such telephony. This requires CMTS support classification traffic management many thousands flows. Continued DOCSIS evolution increasing bidirectional bandwidth requirements these systems. headend equipment also requires full array interface support, including varieties Ethernet, SONET, ATM. Additionally, with fiber installations moving closer closer end-users, CMTS functionality migrating outside headend neighborhood nodes. This constrains system power cost budgets imposes stricter requirements mechanical environmental aspects design. This combination protocol evolution diversity, higher performance, advanced requirements makes CMTS equipment design challenging, especially when combined with cost time-to-market pressures today's market. longer adequate traditional design approaches where each interface line card implemented using separate application specific integrated circuits (ASICs) application specific standard products (ASSPs). With trend toward more distributed implementations, "platform" approach design, where same software leveraged everywhere from distribution points cable headend, offers significant benefits.

MOTOROLA SOLUTION
Motorola's C-PortNetwork Processor (NP) family brings high-service, high-functionality requirements CMTS together highly integrated silicon solution. Perfect both high-end headend power/cost-sensitive industrial temperature environments, C-Port family well suited serve base architectural platform CMTS equipment applications. C-Port network processor distinguished from other fully software-programmable Layer interfaces. This makes capable supporting virtually protocol, including Ethernet, SONET, even DOCSIS implementations. Further, protocols evolve, reprogrammed software support requirements. C-3e with Gbps bandwidth, aimed lower bandwidth applications such distribution nodes, while C-5e with Gbps bandwidth, well suited headend use. addition protocol programmability, C-Port support higher-level programming C-language, enabling fast development advanced features which equipment vendors differentiate their products from competition. With much flexibility, single line card designed interface numerous types modules. This greatly simplifies system architecture because nearly every interface that CMTS needs support based common hardware platform. Traffic classification performed on-chip Table Lookup Unit, which performs 133M lookups/sec. Flows organized Queue Management Unit (QMU), which provides application support queues. Traffic management functions scaled much greater sophistication with addition C-Port Traffic Management Coprocessor (TMC), supporting 256k independent queues powerful three-level scheduling hierarchy. supports policing, monitoring, shaping 256k unique flows, offers virtual channels with multiple levels virtual channel. CMTS line card, each virtual channel assigned different downstream destination, enabling true multiservice access. also available, which provides independent queues addresses power cost-sensitive applications. C-Port family network processors traffic managers share architecturally unified C-language application programming interface (API) that abstracts chip subsystems, allowing your application migrate easily future generations C-Port network processing silicon.
