Calix Aggregates Pseudowires

PETALUMA, Calif. -- Calix, Inc. (NYSE: CALX) today announced that the Ethernet eXtensible Architecture (EXA) Powered Calix C7 Multiservice Access Platform (MSAP) now has two new line cards for the support of pseudowire (PWE) aggregation. As communications service providers transform their networks from SONET to Ethernet, delivery of profitable services such as T1s require the use of PWE to ensure a seamless migration. With the introduction of the DS1-12 PWE and T1-8 PWE line cards to North America's most widely deployed MSAP, the service providers utilizing the C7 for high-density aggregation of T1 lines for mobile backhaul and businesses can now leverage the same C7 MSAP to deliver these services using PWE, enabling an operationally and capitally efficient evolution to internet protocol (IP). By utilizing these new additions to the C7 and the Calix Unified Access portfolio, service providers can keep their access services under one management umbrella with the Calix Management System (CMS), and aggregate DS1 PWE services from Calix B-, C-, or E-Series networks or other standards-based PWE devices.

"As we continue to deploy our fiber-to-the-premises Broadband Stimulus network, T1 services remain a crucial component of our build out," said Ron McCue, chief operating officer of Idaho- and Wyoming-based service provider Silver Star Communications. "We deployed our first C7 in 2006, and by utilizing the transformational power of the Calix C7, complemented by these new pseudowire aggregation cards, we now have the ability to bring these T1s and DS1s into an entirely IP infrastructure. This provides the potential for significant efficiencies in our network, keeps our access network under one management system, and gives us one high-density platform with the carrier-grade features my customers expect."
