Hanaro Telecom Selects Corrigent to Deploy a Converged Broadcasting and
Telecommunication Network for IPTV Services

TEL AVIV, Israel, Sept. 2, 2008 (GLOBE NEWSWIRE) -- Corrigent Systems, a leading
provider of carrier Ethernet transport (CET) solutions for next-generation
service provider networks, today announced that its CM-100 product line was
selected by Hanaro Telecom, Korea's leading ISP, as a main network
infrastructure to deliver premium IPTV services.

Hanaro Telecom, Korea's second largest broadband carrier, plans to offer
differentiated content and value-added services as part of its competitive IPTV
service. A couple of years ago, Hanaro Telecom launched a 100Mbps broadband
access service for residential areas, and plans to increase its penetration
using FTTH technology, as an enabler for its advanced IPTV services.

Corrigent's technology enables Hanaro Telecom to provide legacy TDM services
together with advanced data services, such as broadcast TV (IPTV) over a
converged network infrastructure. 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.
It's designed to deliver highly scalable, cost-effective and resilient video,
voice and data multi-play services.

"Corrigent's Ethernet transport technology will enable us to offer value-added
services to our broadband access subscribers," said Mr. Hyunchan Kim, a team
leader of Hanaro Telecom. "We evaluated solutions from other leading vendors and
chose the CM product line based on its impressive feature set that will allow
Hanaro Telecom to deliver high quality, reliable advanced services to our
customers."

"We are proud to have been selected by Hanaro Telecom," said Izhak Tamir, CEO of
Corrigent Systems. "Hanaro Telecom is a highly innovative operator at the
forefront of advanced service delivery, and we are looking forward to
establishing a long-term partnership. Hanaro Telecom further expands our
customer base and joins the three new customers we recently announced as well as
Media Broadcast in Germany. It is another testament to the momentum in our
business and the leading position of our CM products in the market," he added.
