PMC-Sierra Introduces Family of Carrier-Grade Multi-Service Residential Gateway Reference Platforms for Triple Play Services.

ADSL2+, VDSL2 and PON solutions based on the MSP7100 Gateway SoC Family Deliver Video Performance and Robust Quality of Service

HONG KONG -- PMC-Sierra, Inc. (Nasdaq:PMCS) today announced a suite of multi-service residential gateway reference platforms for the industry's broadest range of advanced broadband access protocols. The MSP7100-based platforms are available today in a range of WAN interface configurations including ADLS2+, VDSL2, Ethernet and EPON to enable robust delivery of carrier-grade services into the digital home. These platforms, based on PMC-Sierra's VoIP-enabled Multi-Service Processor[R] family, allow OEMs and ODMs to rapidly develop high-performance residential gateways optimized for enhanced Triple Play service delivery.

Carriers and cable operators are focused on delivering new high-bandwidth voice, video, media and data services. Enabling these services is driving billions of dollars of investment into solving the "Last Mile bottleneck" by accelerating wide scale deployments of ADSL2+, VDSL2 and Fiber-to-the-Home / Curb (FTTH/FTTC) infrastructure.

Using a common system-on-chip (SoC) architecture and open-source software model, PMC-Sierra offers the following VoIP-enabled multi-service residential gateway reference designs and evaluation platforms:

* PM2326-KIT ADSL2+ residential gateway based on the MSP7120 multi-service processor and PM4381 ADSL2+ AFE;

* PM2327-KIT VDSL2 residential gateway based on the MSP7130 multi-service processor and PM4380 VDSL2 AFE;

* PM2325-KIT Fast Ethernet residential gateway based on the MSP7130 multi-service processor; and

* PM2328-KIT EPON residential gateway based on the MSP7130 multi-service processor and PMC-Sierra's PAS6201 EPON chipset.

"Carriers must support multiple broadband access technologies when faced with a wide range of physical plant conditions in their networks," said Dino Bekis, vice president of marketing and applications for PMC-Sierra's Communication Products Division. "Coupled with demand for new high-bandwidth services, they must deliver a full suite of robust DSL, PON and Ethernet solutions. With these reference platforms, PMC-Sierra has done much of the difficult design work to accelerate time-to-market."

Enabling Enhanced IP Services

Based on a powerful hardware multi-threaded MIPS32 system processor, the MSP7100 solutions deliver:

* High performance, including wire-rate VDSL2 and processing headroom to support RG-hosted service expansion such as gateway-attached storage, remote-access servers, and fixed-mobile convergence;

* Robust QoS protocols necessary to support delivery of carrier-grade IP services into a multi-service home network, including delivery of video and voice with zero-packet loss and minimum packet jitter;

* Full-rate 802.11n wireless LAN bridging with no system performance impact;

* Integrated high-performance IPSec security engine;

* Dynamic multiprocessing core technology, which allows a gateway to simultaneously perform multiple critical functions with deterministic performance; and

* An open-standard programming model using standard MIPS tool chains and C-language programming, enabling developers to leverage a wide range of ecosystem resources.

Linux-Based Software Development Kit Accelerates Development

The MSP7100 gateway platform is supported by the MSP7100 Linux Residential Gateway Software Development Kit (SDK). Based on the Linux 2.6 OS, this SDK enables customers to quickly design high-performance, multimedia and multi-service, VoIP-enabled broadband residential gateways.

Demonstrations at ITU Telecom World

PMC-Sierra will be showcasing its portfolio of solutions for fiber to the home and customer premises equipment, as well as solutions for wireline and wireless equipment at ITU Telecom World in Booth #2008, from December 4 - 8, 2006 in Hong Kong, China. Highlights include:

* A demonstration of the industry's first EPON residential gateway solution with the ability to deliver carrier-grade IPTV and voice services over the home network; and

* The industry's first EPON ONU and OLT silicon devices with key China Telecom features.
