Calix Chooses Wintegra to Expand IP-Based Product Portfolio; Industry's First Purpose-Built, IP-Based FTTN (Fiber-to-the-Node) Platform Utilizes WinPath Access Processors.

AUSTIN, Texas -- Wintegra(TM), a leading provider of access processing semiconductors, announced today that Calix has selected Wintegra's WinPath Access Processor as the primary processor for its E-Series IP Service Edge Node. Calix is the largest telecom equipment provider focused solely on access solutions for broadband service delivery, and its E5 is the industry's first purpose-built, IP-Based FTTN (Fiber-to-the-Node) platform.

Wintegra's WinPath facilitates a wide range of services for the E5, including the latest high-speed broadband connectivity such as ADSL2+ and VDSL2. The factory- and customer-verified protocols supplied by Wintegra, along with straightforward connection to standard PHYs, have enabled Calix to rapidly develop and deploy the E5 system.

"Wintegra has been a strong partner for our E5 system," said Tom Lillig, development lead for the Calix multiservice over Ethernet market unit. "Their silicon and software performed just as predicted, plus their support team was top-notch in getting us to production."

"The Calix E5 is a much needed solution for the FTTN marketplace," said Robert O'Dell, EVP of Marketing at Wintegra. "Calix provides a cost optimized IP-based solution that addresses today's higher performance demands, yet can be managed by service providers via a point and click service activation process."

WinPath is capable of supporting ADSL/ADSL2+ and VDSL2 line technologies at maximum rates. The production quality datapath software is included without incurring either royalties or NRE.
