Corrigent Signs a Long Term Agreement with Media Broadcast GmbH for Deutsche Telekom´s Customer in Germany

Corrigent Systems, a leading provider of Carrier Ethernet
transport solutions for next-generation service provider networks,
today announced that its CM-100 and CM-4000 product lines were
selected by Media Broadcast as a main network infrastructure building
block for network solutions deployed by Deutsche Telekom´s wholesale
business unit, and leased to a leading cable operator in Germany.
Deployments in Lower Saxony and Bavaria begin this year, and rollout
in further regions for the leading cable operator are expected to span
over the next years as part of a 15-year agreement. First shipments of
the CM-100 have commenced.

Corrigent´s CM platforms offer a 10Gbps solution combining
Ethernet transport, full support of legacy SONET/SDH capabilities,
MPLS and RPR technologies, with end-to-end network management, to
allow cost-effective and resilient delivery of video, voice and data
multi-play services.

The CM-4000 supports the gradual migration from today´s
broadcast-centric services to future personalized video services,
offering the highest levels of Quality of Experience (QoE) with
capacity scaling capabilities required to address the expected growth
in on-demand services.

"We are proud to be selected by Media Broadcast for Deutsche
Telekom´s cable operator customers," said Izhak Tamir, President and
CEO of Corrigent Systems. "We are looking forward to establishing a
long term partnership with Media Broadcast and Deutsche Telekom, and
will work with them closely to address their customers´ evolving
needs."
