TAIPEI, Taiwan, April 3 /CNW/ – Chunghwa Telecom, Taiwan’s largest
integrated telecommunications operator, is migrating its international
circuit-switched infrastructure to a Nortel(x) (NYSE/TSX: NT) VoIP next-
generation network (NGN) capable of providing customers with advanced voice,
data and SIP-based multimedia services.

Initially being deployed in Taipei, Kaoshiung and three overseas
locations by the third quarter of 2006, Taiwan’s first international NGN will
simplify business for Chunghwa Telecom while supporting its drive to enhance
competitiveness by enabling new revenue generating services, optimizing
service delivery capabilities, and reducing operational costs.

The NGN will also create a platform for future deployment of Nortel’s SIP-
based IMS (IP Multimedia Subsystem) service delivery architecture. IMS allows
all real-time voice, video and multimedia collaboration services to be
interoperable across any type of network, regardless of device.

“Nortel is the sole provider of VoIP NGN solutions across Chunghwa
Telecom’s northern, central and southern region branches and we are now
bringing these same IP-based, converged network capabilities to its
International Business Group,” said Jackson Wu, managing director, Taiwan,
Nortel. “In addition to 100 percent VoIP NGN market share with Chunghwa, we
are also playing a key role in its milestone transformation into a fully IP
and IMS-enabled international voice, data and multimedia service provider.”

The Nortel VoIP NGN solution for Chunghwa Telecom is based on the Nortel
Communication Server (CS) 2000-Compact, a carrier-grade superclass softswitch
supporting industry-standard VoIP protocols and providing cost-effective
out-of-territory expansion into geographically dispersed markets.

To enable SIP-based multimedia services, the CS 2000-Compact will
incorporate SIP server capabilities to provide Class 4/5 and international
gateway functionality with H.248, media gateway control protocol (MGCP) and
SIP services, in addition to providing Chunghwa Telecom with an investment-
protecting evolutionary path to IMS.

Nortel’s portfolio of gateway and transport elements – media, signaling
and trunk gateways, as well as session control, lawful intercept and network
management capabilities – also forms part of the end-to-end solution.

For its line of VoIP equipment for the carrier and enterprise markets,
Nortel was awarded the Frost and Sullivan 2005 award for Product Line Strategy
