Corrigent Introduces a New Member in Its Carrier Ethernet Transport – CE+T(TM) – Product Family

Corrigent Systems, a leading provider of carrier Ethernet transport (CE+T) solutions for next-generation service provider networks, introduced today the CM-4140, the newest member in its CM-4000 product line, at Light Reading's Ethernet Expo 2008 in New York.

The CM-4140 is a cost-optimized, low-power and small-footprint MPLS-based Carrier Ethernet Transport switch. It offers a full suite of carrier-class Ethernet and TDM services for aggregating residential multi-play services, business connectivity and mobile backhaul applications.

The CM-4140 joins the CM-4314 and CM-4206, the first Carrier Ethernet Transport platforms introduced last year, offering a flexible mix of Ethernet and TDM services. Collectively, the CM-4000 product family facilitates the migration toward an all-IP network.

Corrigent's CM-4140 offers high density GE, 10GE and OC-n/STM-n interfaces supported by 168Gbps non-blocking, fully redundant switching core in a modular architecture. The CM-4140 provides transport-grade capabilities, high service availability, hierarchical OAM for continuous monitoring and SLA metering, and end-to-end service management via the CM-View Network Management System (NMS).

"The CM-4140 is the first switch in the industry to present small footprint with extremely low power consumption while still maintaining full MPLS capabilities and high port fan out," said Sharon Mantin, VP Corporate Marketing for Corrigent Systems. "The CM-4140 switch breaks the cost-performance barrier for MPLS-based platforms, allowing carriers a low cost solution for building their next generation metro networks."
