MSP7160 integrated GPON fibre access gateway device

Share this on social media:

PMC-Sierra has released a Gigabit-speed, multi-service fibre access gateway device with an integrated ITU-T G.984 GPON interface.


The MSP7160 integrates all of the functionality required for a GPON residential gateway, and leverages PMC-Sierra’s proven 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 Quality of Service (QoS) features. It includes integrated multi-channel VoIP terminal adapter capabilities, GPON MAC and SERDES functions with proven interoperability. As the newest addition to the industry’s most complete fibre access gateway portfolio, the MSP7160 is also software compatible with PMC-Sierra’s other MSP7100 family devices.


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 tool chain, 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.



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 2.5/1.25 Gbit/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.
