Chunghwa Telecom Selects Nortel for Taiwan’s First International NGN, All-IP Network

    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
