PMC-Sierra has announced the availability of two fibre access gateway solutions - the MSP7150 EPON/GPON gateway SoC for Fibre To The Home (FTTH) and the MSP7140 VDSL2 gateway SoC for Fibre To The Node (FTTN). These SoCs deliver gigabit-per-second line-rate IPV4/V6 routing, Network Address Translation (NAT), Quality of Service (QoS), encryption and a multi-channel VoIP terminal adaptor, and consume less than 1.5W of power. PMC-Sierra’s fibre access gateway solutions provide OEMs and ODMs with a common platform architecture to support multiple high-speed access technologies in various geographic markets. In addition, service providers can rely on equipment based on PMC-Sierra’s multi-service platform to deliver carrier-grade IP services into the digital home.

“PMC-Sierra is the only company that has shipped millions of devices into production FTTH deployments, and we have leveraged this unique expertise to ensure that our fibre access gateway solutions exceed the performance requirements for FTTH and FTTN topologies,” said Victor Vaisleib, vice president and general manager of PMC-Sierra’s Fibre Access Business Unit. “Our high-performance gigabit-per-second fibre access gateway solution enables the management and delivery of carrier-grade voice, video and data services from the central office to the home.”

“PMC-Sierra’s gateway SoCs use an innovative multi-threaded architecture to provide the gigabit connectivity, flexibility, and the features needed to enable next-generation broadband gateways that accommodate evolving service models,” said Joseph Byrne, senior analyst, The Linley Group.

Powered by a 600MHz MIPS® processor core with cutting-edge hardware multi-threading, the MSP7140/50 solutions deliver:

· Breakthrough performance and flexibility, while consuming less than 1.5 Watts;

· Gigabit-per-second throughput;

· Performance to support new ultra-high bandwidth LAN interface technologies;

· Fully programmable packet processing acceleration to accommodate future service models and home network configurations;

· Headroom to support gateway-hosted applications, such as integrated storage/media server, fixed mobile convergence (FMC) clients, and remote access servers; and

· A Linux-based OS that allows for the leveraging of industry-standard middleware.

The MSP7140/50 integrate three gigabit ports, two USB 2.0 full-speed PHYs (physical interfaces), a 66MHz PCI bus, DDR2 memory controller, multi-channel VoIP terminal adapter, IPSec accelerator and hardware protection against small packet flooding to protect critical services from packet loss during periods of high network activity.

PMC-Sierra’s MSP7150 supports both IEEE 802.3ah-compliant EPON (Figure 1) and ITU-T G.984-compliant GPON (Figure 2) fibre access gateway solutions. With an integrated VDSL2 modem, the MSP7140 is the ideal solution for multi-service VDSL2-based gateway (Figure 3). The MSP7140 device is the first to demonstrate VDSL2 interoperability with all installed central office VDSL1 and VDSL2 chipsets, and is backwards compatible to ADSL2+.

PMC-Sierra offers the following designs and development platforms, including BOM-cost optimised schematics, gerbers and documentation: PM2330-KIT for EPON, PM2331-KIT for GPON, PM2329-KIT for VDSL2, and PM2332-KIT for Gigabit Ethernet fibre access gateways.

An MSP7100 SDK, with Linux OS, powerful networking stack, Linux APIs, VoIP Processing Module (VPM), and a standard MIPS software development tool chain package, is available to support rapid development and leverage the power of the Linux ecosystem. The MSP7100 SDK also supports PMC-Sierra’s MSP7120/30 ADSL2+ and Fast-Ethernet multi-service processors, announced in May 2006.
