Features
OVERVIEW
The MSP7162 Fiber Access Residential Gateway is a second generation device
that combines the multi-service 7100 Series architecture with PMC-Sierra's proven GPON ONT technology
and provides a solution for low-cost, high performance GPON FTTH CPE gateways. It supports an integrated GPON
subsystem, multiple 10/100/1000BaseX MACs, PCI host, a dedicated DSP core for VoIP processing, dual USB 2.0 interfaces,
and a DDR2 memory interface. A Linux software development kit (SDK) that includes voice processing and
GPON management modules are included to streamline application integration and quicken time to market.
This multifunction residential gateway processor addresses carrier
service delivery needs by simultaneously providing superior data
path performance, application processing, and robust voice
processing in a cost/performance efficient implementation. Its 600
MHz multithreaded 7100 Series core dynamically allocates
resources between voice, video, and data processing services, to
guarantee consistent, high-quality broadband networking performance.
It supports gateway designs that enable a service-grade
digital home with the gigabit boost required for IPTV.
Its superior packet processing and WT-156-compliant quality of
service (QoS) performance, with advanced remote management
capabilities, addresses continuously evolving digital home usecases,
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 MSP7162 is a multithreaded SoC that shares the MSP7100
Series architecture and Linux-based embedded software. Its ITU-T
G.984 GPON ONT-standard interoperability is compatible with the
MSP7160 GPON RG.
BENEFITS
The MSP7162 is a second generation device combining a proven
GPON core and SoC. It provides exceptional simultaneous
processing behaviors, which are essential for fiber access
gateways to support triple-play and the evolution to true multiservice
deployments.
PMC-Sierra's residential gateway solution delivers concurrent
complex traffic management, routing, bridging, and firewall tasks
with processing power to guarantee voice, video, and data service
quality. These simultaneous processing capabilities ensure critical
quality of experience (QoE) for all broadband service deployments.
