CenterStage NX3200 CTstage 5iMobile WiMAX Compatible Gateway Devices
Joint International Experimental Trials for
a Japan / China / South Korea NGN Test
Bed that Uses Session Border Controllers
OKI is commencing joint international trials with
KDDI R&D Laboratories Inc. to address changes
in international codec as well as quality control
management. Because these trials will be
conducted as part of R&D into NGN*1platform
technology sponsored by NICT,*2newly
developed codec-changing functions and
MPM*3functions that successfully conform to
international standards will be mounted on the
session border controller, CenterStage®
NX3200, and be installed on the Japan, China,
South Korea NGN test bed. As it progresses with
these experimental trials, OKI is demonstrating
its leadership in establishing international
standards for NGN that it expects to be able to
successfully apply to full-fledged NGN
operations.

Delivery of Mobile WiMAX™ Compatible
Gateway Devices to UQ Communications
OKI delivered its mobile WiMAX compatible
gateway devices to UQ Communications Inc.
Because these devices are configured based on a
mobile WiMAX terminal and a gateway mainframe
with Wi-Fi router functions, Wi-Fi-enabled devices
(wireless LAN terminals including game consoles
and personal computers) can be connected to
mobile WiMAX networks via these devices. By
removing mobile WiMAX terminals from the
mainframe, these can be used as WiMAX-USB
adaptors for personal computers. Therefore, it is
possible to connect to mobile WiMAX networks
via Wi-Fi when at home or directly when outdoors.
Tangram Customer Interaction Center
located in Kunshan, China, Adopts CTstage
Tangram, a major call center outsourcing service
company based in Shanghai, built a 5,000-seat call
center, one of the largest outsourcing call centers in
China, in cooperation with Kunshan City. OKI‘s
system has been adopted as the platform for this
center, and, since April 2009, has been operating
with 300 seats, with Tangram planning to expand
the system gradually. Tangram decided to use
an advanced system leveraging IP technology
to improve its value-added services, such as
management-by-customer and customized
reporting. Consequently, Tangram adopted
CTstage, choosing this product based on its superior
expandability owing its easily customizable features
and its No. 1 share of the Japanese market.
Accompanying the increased use of IP networks for telecommunications, OKI expects that the links
between compatible carriers will increase along with forecasted advances in new communication
services that link telecommunications carrier networks and enterprise networks. Against this
backdrop, OKI’s telecom business will focus on three edge sectors that show growth potential for
NGNs. In the enterprise edge sector, OKI is taking steps to integrate new services accompanied with
the development of networks by telecom carriers and business network systems—accompanying
advances in networks—through a diverse array of unified communications products. In the
consumer edge sector, OKI is making an entry into the mobile phone business for gateway devices
responsive to newly developed WiMAX-WiFi while focusing on the full-fledged development of
GE-PONs*1that is accompanying the expanded use of fiber optic lines. In the carrier edge sector,
OKI is developing high-performance, high-reliability carrier-grade communications servers that
include providing server products that enable new telecom carrier IMS*2services as well as SBC*3
services to achieve seamless service linkage between telecom carriers. All of this is based on network
service platform technology.
Introducing products that take advantages of its strengths in each of these three edge sectors, OKI
is moving forward with business expansion.
In addition, the OKI Group is aiming to expand its service business by utilizing its overall strengths
and promoting the aggressive development of total network services, from network design to
operation maintenance.
