China Unicom's vast global network covers more than 100 countries with direct connections and partnership agreements in place with more than 85 international carriers. We own capacity in a variety of international cable systems and are a member of the consortium implementing the first trans-pacific cable system, Trans Pacific Express (TPE), to link main land China with the United States.

Some of the other cable systems we own capacity on are: China-Japan, China-Korea, FLAG, C2C, China-US, Asia-European, APCN2, Japan-US, PC-1, TPC-5, SAFE, TTC and 13 other international cable systems. China Unicom works with a variety of satellite service partners in providing satellite service to many challenging locations around the world and in meeting the offshore requirements of our clients.

We also operate a network that provides extensive coverage in China and connectivity to over ten countries and regions in the Asia-Pacific area. This network is technologically advanced and conducive to the introduction of the next generation network and 3G technologies. Our network supports a wide range of end-to-end, fixed-line telecommunications and data networking services and enables customized products to be delivered to meet a variety of telecommunications and data network needs in "real-time".

The network we operate consists of transport networks, service networks and support and information systems. The transport networks are primarily fiber-optic based networks covering all Mainland China and the Asia-Pacific countries and regions in which we operate, supplemented by satellite transmission and digital microwave links. The service networks, which support our basic and value-added telecommunications services, consist of our local access networks, including PHS networks, fixed-line telephone switch networks, cellular network, Internet and data service networks and intelligent networks.

The support and information systems include an operation support system and a business support system to support the reliable and effective operation of our networks. In addition, we are building an information technology network and management support system that is designed to ensure the speed and accuracy of our internal information flow. Specifically in China we own and operate:

• Local Access Networks
  We have extensive local access network coverage in our northern service region and to many, if not all, large office buildings and office complexes throughout China. We continue to upgrade our existing copper line local access networks using DSL technology. The total capacity of our DSL access ports is currently over 6 million lines. In addition, our PHS network has a capacity for over 18.5 million lines.


• Fixed Line Telephone Switch Networks
  A substantial portion of our fixed-line telephone networks has been built in the last decade. All of our switches are digital. The network consists of 85 local switch networks and a long distance switch network. The total capacity of local switches is over 80 million lines, and the capacity of long distance switches is over 1.9 million lines. In addition, China Unicom owns international gateways in Beijing, Shanghai and Guangzhou with a total capacity of over 250K lines.


• Internet and Data Service Networks
  We have developed large capacity, high quality and reliable Internet and data networks in our northern and southern service regions. Our Internet networks primarily rely on switch routers with high bandwidth. They are structured with two layers, the backbone network layer and the application layer. Our backbone networks are meshed to achieve maximum reliability and stability. A majority of the main routes in this layer has transmission capacity at 10 Gbps, or 2.5 Gbps. As of June 30, 2007,we also had a backbone IP network with a total bandwidth over 1200 Gbps and international outbound bandwidth over 250 Gbps. In addition, this network allows us to provide services such as IP-VPN, Internet data center, e-commerce and video-on-demand services. Our data network system includes a digital data network and a frame relay and ATM network. These networks cover all cities and counties in the northern region and substantially all cities and counties in the southern region.
