OKI Expands its Lineup for CenterStage(R) NX Series, the Carrier Grade Communication Server for IMS and NGN

With ATCA Platform, OKI Offers Industry's Highest Scalability for
Subscriber Capacity
TOKYO--(Business Wire)--
Oki Electric Industry Co., Ltd. (TOKYO:6703) today announced it
has added CenterStage(R) NX5000 R3, NX5100 R2 and NX5200 R2 to its
lineup of carrier-grade communication server for IMS and NGN. The new
CenterStage NX 5000 Series now uses Advanced-TCA(1) (ATCA), which is
the standard hardware platform in the telecom industry. OKI also adds
two additional models to its lineup.

"We believe our new NX 5000 Series will enable telecom carriers to
build IMS(2) core networks for both fixed and mobile networks and to
offer a variety of services to their users by connecting with
application servers," said Kichiro Akino, President of Network Systems
Company at OKI. "We will continue to provide these products to
customers having networks of various sizes in the NGN, IP telephony
and mobile communication markets."

The newly added models include:

-- CenterStage NX5000 Series (NX5000 R3, NX5100 R2, NX5200 R2)
These are IMS compliant session control servers enabling S-CSCF(3),
I-CSCF(4), P-CSCF(5) and MGCF(6) functions. ATCA platform is now
applied in the NX5000 series.
-- CenterStage NX3500
NX3500 is an IMS compliant media resource server supporting MRF(7)
function. Under the control of the NX5000 series, the server can
offer a flexible and scalable voice-based guidance service.
-- CenterStage NX1200
NX1200 is an IMS compliant media gateway with MGW function and
enables interworking between NGN, IP telephony networks and Public
Switched Telephone Networks. NX1200 offers media conversion
functions under instruction of NX5200.

Many telecom carriers require higher reliability, higher
performance, higher capacity and longer life cycle for their equipment
used for NGN and IP telephony networks. It is now important to provide
products with high network processing power, scalability, and design
flexibility while maintaining carrier-grade reliability.

To meet such needs, OKI has adopted the ATCA platform, the
industry hardware standard platform, to its CenterStage NX5000 Series.
With this ATCA blade, OKI's NX5000 Series now offers improved hardware
maintenance, longer durable period compared to general purpose
rack-mount servers, smaller size and ensures the industry's highest
scalability. The ATCA blade is also loaded with the new SAF-compatible
version of "CenterStage HAPF," OKI's well-established high
availability middleware that is currently used in the NX series. As
the company also includes a general-purpose server in its lineup, OKI
can now offer CenterStage to all customers, whether having small scale
networks or large.

The CenterStage NX5000 Series include a dual core CPU on the ATCA
board, supporting up to 800 thousand subscribers. The NX5000 ATCA
blades can be placed into a single ATCA shelf, which then can serve a
maximum of 4.8 million subscribers. Therefore, the installation space
is reduced to one-third compared to OKI's general-purpose rack-mount
servers and power consumption is also reduced to one-third, which also
helps in reducing operating costs. Because the NX5000 Series can be
supported in the same ATCA shelf, equipment design optimization can be
achieved corresponding to various traffic conditions.
