Pseudowire aggregation cards available for Calix C7

Calix, Inc. (NYSE: CALX) has unveiled a pair of new line cards for its Ethernet eXtensible Architecture (EXA) Powered Calix C7 Multiservice Access Platform (MSAP) that support of pseudowire (PWE) aggregation. The new DS1-12 PWE and T1-8 PWE line cards operators to use the C7 MSAP to aggregate T1 lines for mobile backhaul and businesses as well as deliver these services using PWE.

Calix, Inc. (NYSE: CALX) has unveiled a pair of new line cards for its Ethernet eXtensible Architecture (EXA) Powered Calix C7 Multiservice Access Platform (MSAP) that support of pseudowire (PWE) aggregation. The new DS1-12 PWE and T1-8 PWE line cards operators to use the C7 MSAP to aggregate T1 lines for mobile backhaul and businesses as well as deliver these services using PWE.

The new additions to the C7 and the Calix Unified Access portfolio enables a single management umbrella for access services using the Calix Management System (CMS), regardless of whether the service provider is aggregating 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."

The C7 MSAP is built to support both Ethernet and SONET transport; the new cards further position the platform to efficiently enable network evolution from legacy to IP services, Calix asserts. The company adds that C7 also reduces costs and management complexity because it can:

  • Aggregate T1 PWE flows from Calix ONTs (both the 766GX and 743GE) and standards-based PWE end points
  • Provide integrated bit error rate test (BERT) for circuit acceptance and remote troubleshooting
  • Deliver 1:N protection for carrier-grade reliability
  • Increase GR303/TR08 processing capacity by a factor of two.
