ZyXEL Metro Ethernet Switches Receive MEF Tier One Quality Certification

Hsinchu, Taiwan, February 13, 2009 – Metro Ethernet switches manufactured by ZyXEL Communications Corp. (TSE:2391) have passed three rigorous tests to earn Tier One level of quality. ZyXEL M-Series Carrier Ethernet Switches, MGS-3712/MGS-3712F and MES-3728, are aligned with carrier-class standards for Ethernet Private Line (EPL), Ethernet Virtual Private Line (EVPL), and Ethernet LAN (E-LAN) of Metro Ethernet Forum (MEF) and certified as MEF-9 and MEF-14 compliant. The certification for the three service standards demonstrates that ZyXEL Carrier Ethernet Switch technology meets Tier One quality standards of industry leading network equipment suppliers.

The Metro Ethernet Forum is a global industry alliance comprised of more than 145 active members representing Carrier Ethernet industry groups. The forum develops technical specifications and implementation agreements to promote interoperability and deployment of Carrier Ethernet worldwide. The program enables service providers to make informed decisions and promote reduced service and customer equipment risks. In addition, it aims to decrease expenses, reduce testing time, and enhance the ability to respond faster to demand for Carrier Ethernet services.

ZyXEL Ethernet switches have historically aligned with MEF standards. For this certification, ZyXEL MGS-3712/MGS-3712F and MES-3728 not only met the testing standards of EPL service, but also the testing standards of EVPL and Ethernet LAN E-LAN.

"ZyXEL's excellent Ethernet quality has been recognized by leading service providers, such as CHT (Chunghwa Telecom), for years," said Alpha Chen, VP of ZyXEL's Enterprise Solution Strategy Business Unit. "This certification once again demonstrates that our outstanding Ethernet technology performance meets the challenging demands of operators in the construction and development of Carrier Ethernet networks."
Chen said service providers are looking for an easily deployed carrier-class solution with intelligence and minimal capital investment. "ZyXEL's comprehensive M series Ethernet switches provide architectural flexibility and intelligent service delivery mechanisms to help our clients build a scalable and reliable service-driven metro network for maximum performance."

ZyXEL Ethernet solutions will be demonstrated at Cebit 2009 - Hall 13, Booth C70 from March 3-8.
