MSP7162 GPON RG

Fiber Access Residential Gateway

Product Overview

The MSP7162 Fiber Access Residential Gateway is a second gener­ation device that combines PMC-Sierra’s multi-service 7100 Series
architecture with proven GPON ONT technology for low-cost,
high performance GPON FTTH CPE gateways. It supports an
integrated GPON subsystem, multiple 10/100/1000BaseX MACs,
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.

• Provides essential headroom to address
requirements for evolving services, service
bandwidth, and digital home infrastructure:
stronger management/control, interworking of
HAN technologies for end-to-end QoS and
gateway application processing

• Supports classification, mapping, and filtering,
according to L2/L3/L4 fields, double-tagged
VLANs, MLD and IGMP multicast

• Data path processing compliant with DSL forum
Working Text WT-156 at Gigabit rates.

• Flexible queuing features enable queuing per
user/service with per-queue WFQ/SP scheduling,
shaping, and policing

• Provides exceptionally fast networking
performance to leverage the full potential of next
generation access networks and ultra-high speed
home networking technologies.

• Greater packet processing permits advanced QoS
features for robust service delivery, for high
service bandwidth and guarantees for service
growth

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
