ALL-IP Fixed Telephone Network Leads the World

The high-quality IP backbone network that supports "Hikari-One", "KDDI Hikari Direct" and "Metal-plus phone" is the unique Content Delivery Network (CDN) developed by KDDI. KDDI is leading the way in constructing an efficient telecommunications network utilizing IP technology. Existing fixed telephone switches will be replaced with soft switches by the end of fiscal 2007, when KDDI plans to become the first in the world to achieve an all-IP fixed telephone network. In addition to lowering the costs of telecommunications equipment, this will enable call quality equivalent to that of fixed telephone networks, provide greater reliability, and add more value to our services.
KDDI will achieve broadband service compatible with every type of access line.
