Features
OVERVIEW
The MSP7160 residential fiber access gateway device combines the Multi-Service 7100 Series architecture with PMC's proven GPON WAN interface for low-cost, high performance GPON FTTH CPE gateways. The MSP7160 complements the MSP7100 Series of Multi-Service Processors with a key set of interfaces, and critically, it shares the common architecture and shared software.
The MSP7160 device addresses carrier service delivery needs by simultaneously providing superior datapath performance, application processing, and robust voice processing, in a cost/performance efficient implementation. The MSP7160's high-performance multithreaded 7100 Series core includes the ability to flexibly allocate resources between these diverse processing requirements, and provide dynamic multifunction guarantees. The gateway designs supported by the MSP7160 enable a service-grade digital home with the gigabit boost required for IPTV.
This new breed of RG processor ensures simultaneous functionality for voice, video, and data, resulting in broadband service guarantees. The MSP7160's superior packet processing and quality of service (QoS) performance with advanced remote management capabilities addresses evolving digital home-use cases, and provides carriers the ability to control in-home service distribution which is essential for a high-value consumer experience. This powerful engine provides the necessary performance and connectivity for service revenue-generating broadband portals.
The MSP7160 supports integrated GPON serdes, two 10/100/1000 GE MACs, dual USB2.0 interfaces, and has a DDR2 memory interface. The MSP7160 includes a Linux software development kit (SDK), with voice processing and GPON management modules. SYSTEM PROCESSOR

BENEFITS
Exceptional simultaneous processing behaviors are essential for fiber access gateway support for triple play and the evolution to true multi-service deployments. PMC-Sierra's RG solution enables complex traffic management, routing, bridging, and firewall tasks concurrently with the ability to support processing guarantees for voice, video, and data services. These simultaneous processing capabilities ensure critical quality of experience (QoE) for all broadband service deployments.

Software
The MSP7160 is supported by a Linux software development kit (MaxMT Linux SDK). The SDK enables designers to quickly and easily build high-performance, feature-rich gateways and includes a voice processing module (VPM) VoIP firmware suite and GPON OMCI management stack.
The MSP7160 and SDK are supported by standard tools from industry leading vendors as well as GNU development tools (compiler, debugger, EJTAG support, etc.)
For more details about the software development environment, refer
to the MSP7100 Series SDK Product Brief.
APPLICATIONS
