ZyXEL Forays into VoIP Market with Integrated Voice and Data Solutions

(Hsinchu, March 8, 2004) ZyXEL Communications, world's leading broadband access solutions, today announces its comprehensive VoIP (Voice over IP) solutions for telecom and ISP companies. The solutions are comprised of ADSL IAD (Integrated Access Device), Station Gateways for connecting user-end ADSL modem and telephone set, as well as VoIP Wi-Fi Phone and ATA (Analog Telephone Adapter) for end users.

"As the need for Internet voice, data, and video exchange applications grow, it has become a challenge for Internet service providers to offer more value-added services aside from just expanding the bandwidth," said Albert Ju, Director of ZyXEL's CPE Product Division. "With the emergence of VoIP technology, service providers are finally enabled to provide a viable alternative to conventional long-distance phone calls, and more value-added ADSL broadband services to attract new subscribers, therefore generate more revenue and gain competitive advantages."

Thanks to the latest VoIP technology employed in ZyXEL's VoIP CPE products, the users are enabled to experience the crystal-clear voice quality, as well as the powerful, fully integrated features. Through the wide-ranging product lines, service providers will be capable of providing advanced voice and data integration with optimal combination of ZyXEL solutions.

ZyXEL's new VoIP lineup supports SIP (Session Initiation Protocol), the key open industrial standard for integrating IP network and conventional PSTN network. The SIP does not only bridge the traditional voice service and Internet technology through IP network, but bring Instant Messaging, mobility, video application together as well. As a result, ZyXEL's SIP-compliant VoIP solutions will give a boost to the competitive advantage of the VoIP services offered by IP telephony service providers.

Furthermore, the VoIP solutions from ZyXEL are flexible in supporting QoS (Quality of Service). Depending on the deployment strategies, the service providers have the freedom to prioritize the voice packets to ensure the best voice quality. With ZyXEL's renowned ease-of-use and excellent user interface, the system administrators will be empowered to perform remote configuration, management, monitoring, and trouble shooting through ZyXEL's Vantage CNM (Central Network Management) at a single central site, thus effectively simplify the maintenance routines and reduce the supporting cost.

The VoIP Wi-Fi Phone is available now, becoming the first to reach the market in ZyXEL's VoIP lineup; and the remaining members are scheduled to be delivered successively during the first and second quarter of 2004.
