SAN JOSE, Calif. -- Corrigent Systems, a leading provider of Packet ADM (Add Drop Multiplexer) for next-generation transport networks announced today that it opened an office in Korea. With a population of 49 million and one of the worlds most advanced telecommunications infrastructures, Korea represents a significant opportunity for Corrigent's CM-100 product line.

According to the latest statistics from the Organization for Economic Co-operation and Development (OECD, June 2005), Korea ranks first worldwide in broadband penetration among industrialized countries. For every 100 inhabitants there are 25.5 broadband subscribers. This compares with 19.2 in Canada, 16.4 in Japan and 14.5 in the US. In addition, Korea has 1,239 phone subscribers, fixed and mobile, for every 1,000 people in the country.

Some carriers create separate overlay networks for wireline, cellular and broadband services. This creates a complex and expensive network to build and manage. Corrigent's CM-100 Packet ADM enables service providers to converge their voice and data networks onto a single transport network. This provides opportunities for savings on equipment and operation. In addition, the CM-100 gives carriers the ability to reach business users with Ethernet service on the same transport equipment they would use for all other service offerings.

"Korea is one of the most advanced telecommunications markets in the world, and we believe that the 10Gbps CM-100 is the ideal transport equipment in this rapidly growing market," said Akio Ogiso, VP of Asia Pacific for Corrigent Systems. "The opening of our new office demonstrates our commitment to the Korean market, and our expectations to work closely with the leading carriers in this country."

Dr. Francis Tai Noh is Corrigent's Country Manager in Korea. Prior to joining Corrigent, Dr. Tai Noh was with Lucent as Managing Director for Network Planning and Systems Engineering Center in Korea, and with Marconi as President of Marconi Korea. "Korea's extraordinary broadband penetration drives carriers in this market to look for packet-optimized transport solutions. Our new office in Korea allows us to introduce Corrigent's Packet ADM product line to these carriers and benefit from the healthy growth the Korean market is experiencing," said Dr. Noh.
