PMC-Sierra Inc. has announced a gigabit-speed, multiservice fiber access gateway device with an integrated ITU-T G.984 Gigabit Passive Optical Network (GPON) interface. The MSP7160 integrates all of the functionality required for a GPON residential gateway, and leverages PMC-Sierra's GPON interoperability and software layers to improve performance and reduce OEM time-to-market and development costs. The availability of this new device will enable carriers to expand HD video service offerings to consumers through the mass deployment of high-bandwidth broadband and support necessary enhancements to applications, such as video and picture sharing, P2P and data storage.

The MSP7160 delivers gigabit-per-second IPv4 or IPv6 routing, Network Address Translation (NAT) and QoS features. It includes integrated multichannel VoIP terminal adapter capabilities, GPON MAC and Serdes functions with proven interoperability. The MSP7160 is also software-compatible with PMC-Sierra's other MSP7100 family devices.

"First- and second-generation FTTH deployments required both an ONT box and a separate Residential or Multi-service Gateway box," said Jag Bolaria, senior analyst at The Linley Group. "A high-performance integrated GPON residential gateway device puts both functions into a single box with a single device, enabling significant savings in equipment cost, deployment cost, network complexity, and field maintenance overhead. For the OEM, the ability to use PMC-Sierra's software-compatible device family for virtually any geographic deployment is a big plus, and the device's interoperability addresses an important carrier goal, the ability to mix and match devices in the field."

Support software and tools include PMC-Sierra's GPON ONT OMCI management client and API, a full suite of field-proven voice processing components, the MSP7100 Series Linux SDK toolchain, middleware software packages and a complete third-party pre-integrated residential gateway application. Reference designs and development platforms are available and include BOM-cost optimised schematics, gerber files and documentation.

Breakthrough performance
The MSP7160 processing architecture features a MIPS 600MHz multi-threaded core, common in architecture to all MSP7100 devices. This architecture enables hitless context switching between simultaneous processing for tasks associated with multiple services (data, video, voice, fixed mobile convergence, storage) resulting in robust quality of service and deterministic QoE for these services. It is designed to support new residential gateway functions and services such as integrated storage/media server, fixed mobile convergence (FMC) clients, remote access server and content management. The integrated GPON function includes capabilities based on the deployment-hardened GigaPASS architecture to support full-rate 2.5/1.25Gbit/s GPON without processing burden. A virtual DSP engine provides guaranteed cycles for voice processing tasks. The MSP7160 also provides a full complement of interfaces including Gigabit Ethernet, Hi-Speed USB2.0 and PCI.

The MSP7160 GPON Fiber Access Gateway device is already sampling.
