ZyXEL Announces ES-1528 28-port Web-Managed Switch for Small- to Medium- sized Business

ExtraSmart(tm) Technology Enables "Auto DoS Attack Prevention" and "Auto VoIP" with Just a Click

Hsinchu, February 26, 2007 -- ZyXEL Communications (TSE: 2391), the world's leading broadband access solutions provider, today unveils its new-generation switch powered by ZyXEL's exclusive "ExtraSmart(tm)" intelligent technology. Designed with the "Easier Operation, Smarter Network" in mind, the new switch series is spearheaded by the ZyXEL ES-1528. The ES-1528 has advanced intelligent networking chips, as well as ExtraSmart(tm) technology that enables "Auto DoS Attack Prevention" and "Auto VoIP" features with simple clicks in the management interface. In addition, the ES-1528 also comes with intuitive management modules to provide a Web-based interface for effortless network administration.

"The learning curves of most so-called 'smart' switches on the market are still steep for SMB/SBs with limited IT staff and budget," said ZyXEL. "ZyXEL's ExtraSmart(tm) technology simplifies network security and VoIP the configurations that used to be very complicated. With just a few clicks, ES-1528 can not only provide DoS protection instantly, but also identify and grant higher priority to voice packets for smarter, easier network operations.

Extra Secure Auto DoS Attack Prevention
For SB/SMBs, the one-click Auto DoS Attack Prevention of ZyXEL ES-1528 is the best answer to the highly concerned network security issue. With the DoS prevention activated, ES-1528 can detect and deter typical DoS attacks that enhance security protection. Moreover, the ES-1528 also boasts Broadcast Strom Control, 802.1Q VLAN, port security and administrator authentication to further enhance its already solid protection.

Auto VoIP with Extra QoS
Whereas VoIP can reduce the cost of voice communication for SMB/SBs significantly, the unreasonably complicated configuration process often prohibits users from deploying the service. The smart Auto VoIP feature offered by ZyXEL ES-1528 can identify all incoming and outgoing packets automatically, and gives these packets the highest priority for the best voice quality possible. In addition, ES-1528 supports four priority queues per port and port-based rate limiting policies for guaranteed performance and service quality.

The ZyXEL ES-1528 is capable of Non-Blocking Switching Fabric at 12.8 Gbps, and has 24 10/100Base-T RJ-45 ports plus four Gigabit uplink ports (two RJ-45 ports and 2 SFP slots) for different interface needs. It also supports 802.3ad Link Aggregation that enables flexible expansion to uplink bandwidth and data paths for better transmission stability.

ZyXEL ES-1528 is now available and can be ordered via ZyXEL's global sales network of system integrators and value-added resellers. To find a ZyXEL distributor nearest to your location, visit the information site at http://www.zyxel.com/web/where_tobuy.php
