Corrigent Releases New Packet Transport Switch Product Line

Corrigent Systems, a leading provider of Packet Transport
equipment, announced today the release of 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. This
new product line builds on Corrigent's industry-leading packet
transport technology and 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 non-blocking switching capacity of 320Gbps and 160Gbps
respectively, scalable to 640Gbps and 320Gbps. It provides unmatched
in-service scalability through the introduction of advanced bonding
technologies, which allow network operators to scale network links to
up to 100Gbps per link.

The CM-4000 PTS facilitates the migration towards 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
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 CM-4000 PTS also offers a unique application and service-aware
traffic management scheme, which guarantees end-to-end performance
during congestion, and enables dynamic bandwidth reclamation and
optimal bandwidth utilization at all times. With the CM-4000, service
providers can guarantee end-to-end performance for their services, but
also 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," said Gady Rosenfeld,
VP 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 is unveiling the CM-4000 PTS product line simultaneously
this week at two leading telecommunications events: the C5 World Forum
in Milan, Italy and at the OFC/NFOEC exhibition in Anaheim,
California.

The CM-4000 PTS product line addresses service providers'
challenges in building carrier-class, general-purpose metro transport
networks. Among the many benefits the CM-4000 offers are:

-- In-service scalability of network-side links of up to 100Gbps
through advanced link bonding technologies

-- Universal packet transport of any combination of TDM and
packet traffic, from 100% TDM to 100% Ethernet

-- Fully non-blocking switching capacity of 320Gbps scalable to
640Gbps

-- Support for the complete range of PDH, SONET/SDH, Fibre
Channel and Ethernet interfaces

-- Advanced TDM-to-Ethernet interworking functions on
high-density, multi-service SONET/SDH and PDH interfaces

-- Application and service-aware traffic management to overcome
net neutrality, allowing carriers to benefit from higher
margins on preferred services

-- Multi-rate and Multi-protocol configurable interfaces for
quick and flexible service activation

-- Colored optics and OTN interfaces, for cost-effective
integration with the photonic network

-- Transport-class availability with guaranteed sub-50ms service
recovery over any topology

-- Hierarchical, fully-correlated, multi-layer OAM, providing
transport-class performance monitoring, diagnostics and
troubleshooting functionality

The capabilities of the CM-4000 PTS translate into clear business
advantages for service providers offering or looking to offer the
following end-user applications:

-- Residential Triple Play services (VoIP, Video and Internet
Access)

-- Business Ethernet, including point to point and multipoint
Ethernet services

-- 3/3.5G wireless and WiMax backhaul

-- Peer-to-peer and on-demand content distribution
