Radisys Announces Industry`s First Integrated 40G ATCA Platform

4th Generation ATCA Products Enable Smooth Transition to High Bandwidth
Applications Such as LTE, WiMAX, Femtocell Gateways and Video
HILLSBORO, Ore.--(Business Wire)--
RadiSys Corporation (NASDAQ: RSYS), a leading global provider of embedded
computing solutions for telecommunications and other industries, today announced
the RadiSys ATCA 4.0 initiative, the company`s 4th generation of AdvancedTCA
(ATCA) products that are designed to support the next generation of high
bandwidth applications. A first in the marketplace, this fully integrated
platform features the latest technology in the industry, incorporating a
10GBASE-KR and 40GBASE-KR4 capable backplane and 40G switching capability. As
Telecom Equipment Manufacturers (TEMs) focus on building next generation network
elements, including 4G and Broadband, the RadiSys ATCA 4.0 platform will provide
them with the next generation switching, power and cooling that they require.

"As the proven leader in ATCA platform deployments, RadiSys understands the time
to market pressures that our TEM customers face in the next generation mobile
infrastructure market, and the technical and product decisions that they need to
make now to stay in front of the market," said Anthony Ambrose, Vice President
and General Manager, Communications Networks, RadiSys. "Our 4th generation 40G
platform announcement reinforces our technology leadership that we delivered in
our 3rd generation 10G platform, and demonstrates how we anticipate customers`
future requirements better than any other company."

The ATCA 4.0 40G platform follows on the heels of the 3rd generation of
market-proven RadiSys platforms that enable 10G applications. The overall demand
for higher bandwidth mobile data and video services continues to sustain steady
growth in 3G markets, and this demand will accelerate as mobile networks deploy
broadband access speeds. TEMs striving to meet this demand for 3G services and
laying the groundwork for 4G networks can leverage RadiSys` ATCA 4.0 platform
solution. It is a fully backwards compatible solution, thus protecting the
customer`s current investment in 3G networks, while ensuring a smooth and
economical transition to the ATCA 4G environment.

"With 3G, we have already seen a fundamental shift from wireline to wireless
services. The next major shift in communication technology will be to high speed
Internet and data access on mobile devices, driven by next generation mobile
radio access and packetized core networks," said Lee Doyle, Vice President and
General Manager, Network Infrastructure, IDC. "Mobility will become the number
one driver of Internet usage and video services going forward and the RadiSys
ATCA 4.0 platform is well positioned to provide the flexibility, scalability and
performance to meet current, and future, mobile subscriber demands."

The next generation platform builds on RadiSys` existing success with 10G
applications and infrastructure with deployed applications such as 3G wireless,
IMS, IPTV and miscellaneous gateways. Platform integration has been a key
benefit that helps RadiSys` current customers achieve a rapid time-to-market.
The ATCA 4.0 platform will continue to build on the level of integration
available in the existing generation of products. In addition to the complete
and comprehensive platform validation including backplane and thermal
validations with the 40G switch and chassis, the 4.0 platform also includes
software integration including switch management, Linux and middleware. With
ATCA 4.0, RadiSys is extending its 10G platform leadership in the market and
providing a smooth path to fully integrated 40G platforms.

About RadiSys ATCA 4.0

RadiSys ATCA 4.0 products provide the highest scalability and density possible
in an ATCA form factor with a 4x performance improvement in both switching and
processing capabilities over 10G components. These 4th generation ATCA platforms
combine a 40G chassis, a 40G switch and other 10G and 40G assets in a
pre-integrated platform that enables the deployment of next generation 4G
applications. The 40G chassis includes enhanced per-slot power and cooling
capability along with true 40G backplane connectivity. The 40G switch with
field-proven switch management software provides increased I/O density and
native 40G switching to the node slots. The reuse of the switch management
software will provide consistent API access, thereby providing reuse of any
development with the existing 10G switch. Additionally, RadiSys will be
expanding the switch management capabilities to include a "node router" which
enables the elimination of a stand-alone router that would typically provide
connectivity between an edge device and the transport network. RadiSys`
investments today in next generation ATCA products ensures a smooth transition
for customers from 10G products to 40G, protecting their investment in ATCA.
