ZyXEL Enters Gigabit SOHO Switch Market with New Dimension GS Series

Hsinchu, Taiwan, May 19, 2003 -- ZyXEL Communications Co., (TSE: 2391) world's leading broadband access solutions vendor, today unveils Dimension GS, a new series of 100/1000Mbps Gigabit Ethernet Switch products aiming at today's small office and home office (SOHO) environment. Consisting of GN-650T Gigabit PCI network adapter, GS-105/108 5/8-port 100/1000Mbps Gigabit desktop Ethernet Switch, the Dimension Gigabit SOHO Series offers stunningly fast data transfer speed, in addition to a slim and plug-and-play design, which facilitates the SOHO users to exploit their broadband connection.

"The broadband switch market is now undergoing another wave of renovation," said Dr. Yuh-Long Chen, the Senior Vice President of ZyXEL. "Thanks to the prevalence of broadband connection in the smaller offices and households, which expands the availability of online multimedia and video contents, the broadband users are demanding speedier switches to meet their needs."

"Despite the fact that ZyXEL is not a senior citizen in the switch arena, we are determined to take the lead." Dr. Chen continues, "By grabbing a significant share of the newly flourished Gigabit SOHO Switch market, the ZyXEL brand will quickly build up the exposure and market share it deserves. In the mean time, ZyXEL's advantage on R&D will be fully taken advantage of, in order to develop a series of Layer 2 and Layer 3 switch products that would strengthen ZyXEL's position as a prestigious player in the higher- and lower-end switch markets.

The ZyXEL Gigabit SOHO Ethernet Switch Series complies to the IEEE802.3 10Base-T, IEEE802.3u 100Base-TX, and IEEE802.3ab 1000Base-T standards, and the models provide five (GS-105) or eight (GS-108) 10/100/1000M switching ports respectively. GS-105 and GS-108 are capable of detecting the speed of all ports and full/half-duplex transfer mode, as well as supporting the IEEE 802.3x Flow Control protocol.
