MARCH 30, 2007 -- Packet-transport equipment provider Corrigent Systems (search for Corrigent) has released the CM-4000 Packet Transport Switch (PTS) series, a new line of advanced transport products designed to provide highly scalable end-to-end delivery of packet and TDM services over a single, converged transport infrastructure. According to the company, this new product line is designed to provide a universal transport solution, capable of delivering any traffic mix, from 100% circuit-based TDM to 100% Ethernet services with high cost efficiency.

The CM-4000 PTS, which includes the CM-4314 and CM-4206, provides full nonblocking switching capacity of 320 and 160 Gbits/sec, respectively, scalable to 640 and 320 Gbits/sec. It provides in-service scalability through the introduction of advanced bonding technologies, which allow network operators to scale network links to up to 100 Gbits/sec per link.

The device facilitates the migration toward all-IP by providing network operators with a viable path to convergence through the introduction of SONET/SDH-to-Ethernet interworking and high-port-density Ethernet interfaces. While still providing full support for circuit-based TDM services and applications, the CM-4000 enables service providers to cost-effectively offer standards-compliant E-Line, E-LAN, and E-TREE Ethernet services. This, the company claims, facilitates the delivery of profitable advanced IP services such as residential triple-play, business Ethernet, and the backhaul of 3G and 3.5G wireless and WiMAX services over a single, converged packet transport infrastructure.

The transport switch also offers a unique application and service-aware traffic management scheme, which the company says guarantees end-to-end performance during congestion and enables dynamic bandwidth reclamation and optimal bandwidth utilization at all times. Service providers can differentiate between application instances, effectively allowing carriers to benefit from higher margins on preferred services and overcoming net neutrality.

Michael Howard of Infonetics Research says, "Our research shows that many service providers around the globe are looking for a single metro network element that is capable of providing both circuit and packet-based transport. The CM-4000 is one of a new breed of such products embodying the characteristics that large carriers are looking for to build their next-gen metro networks."

"Packet transport is the next step for carriers looking to implement Ethernet-centric transport networks," states Gady Rosenfeld, vice president, marketing, for Corrigent Systems. "Our CM-4000 Packet Transport switch represents the merger point for transport and Ethernet, allowing carriers to benefit from Ethernet's ubiquity, simplicity and cost effectiveness, and yet maintain the general-purpose characteristics of the transport network."

Corrigent unveiled the CM-4000 PTS product line simultaneously this week at the C5 World Forum in Milan, Italy, and at OFC/NFOEC 2007 in Anaheim, CA.
