Corrigent Extends Its Packet Transport Solution With New Platforms

Corrigent Systems, a leading provider of packet transport
equipment for next-generation transport networks, announced today the
release of new product additions to its market leading packet
transport offering, designed to provide the access component in
Corrigent's end-to-end packet transport solution.

The CM-104 is a compact fully-redundant and modular Packet
Transport Switch (PTS). The CM-104 PTS is six rack-units in height,
and includes four horizontal user slots for all the
generally-available CM-100 User Interface Modules, including Ethernet,
PDH, SONET/SDH, and storage interfaces. It supports 10Gbit/s or
2.5Gbit/s network-side interfaces, and as the rest of the CM-100
product line, it is based on MPLS, RPR and SONET/SDH to provide a
carrier-class packet transport solution. It is designed to provide a
converged solution for operators offering a combination of carrier
Ethernet, TDM and Fibre Channel services.

The CM-21 Packet Transport Switch provides an Ethernet access
solution for residential and business customers. The CM-21 may be
subtended from Corrigent's CM-100 Ethernet user interface modules in
ring, linear and tree configurations. It provides twenty-four Gbits/s
of non-blocking switching capacity, making it ideal for
bandwidth-intensive, and interactive applications such as IP
Television (IPTV), voice over IP (VoIP) and Video on Demand (VoD). It
supports a full suite of Ethernet E-LINE and E-LAN services as defined
by the MEF. The CM-21 product line comes in four different
configurations, all in a single rack unit, supporting optical or
electrical fast-Ethernet and gigabit-Ethernet interfaces, including
redundant AC and DC power options.

"The addition of the CM-104 and CM-21 product line to our family
of packet transport products allows us to address new markets, and
expand the reach of our packet transport solution," said Gady
Rosenfeld, Vice President of Marketing for Corrigent Systems. "It
allows more service providers to benefit from a converged metro/access
packet transport network solution with unified end-to-end management."

Corrigent will be presenting its CM-100 and CM-21 end-to-end
packet transport solution at the live interoperability event sponsored
by the European Advanced Network Test Center (www.eantc.de) hosted by
the Carrier Ethernet World Congress in Madrid, Spain. Corrigent will
showcase the delivery of Ethernet services, IPTV, VoIP, and TDM over a
converged packet transport network solution with Ethernet OAM (per
IEEE 802.1ag), point-and-click provisioning, and end-to-end Ethernet
interworking.
