Data Communication Services and Internet Data Center Services  We provide a wide range of managed data services, including frame relay services, asynchronous transfer mode services,  and VPN services. Frame relay services provide high-speed data communications linking remote sites. Asynchronous transfer mode  services are used to handle high-bandwidth, integrated voice, video, data and internet traffic between sites.  Internet data centers are facilities providing the physical environment necessary to keep computer network servers running at  all times. These facilities are custom-designed with high-volume air conditioning temperature control systems, secure access, reliable  electricity supply and connections to high-bandwidth internet networks. Data centers house, protect and maintain network server  computers that store and deliver internet and other network content, such as web pages, applications and data. We currently have the  greatest number of internet data centers in Taiwan compared to our competitors in Taiwan. We offer co-location, web hosting and  application service provider services.  Our internet other services include government services, corporate solution and Information and Communications  Technology, or ICT, services.  Our international fixed communications business include international long distance telephone services, international leased  line services, international data services, satellite services and international other services.  We provide international long distance telephone services in Taiwan. Total revenues from international long distance  telephone services comprised 6.5%, 6.4% and 5.7% of our revenues in 2009, 2010 and 2011, respectively. In addition, we provide  wholesale international long distance services to international simple resale operators that do not possess their own telephone network  or infrastructure.  Since international fixed communication services have been open for competition since 2001, we expect competition in this  line of business will continue to intensify. Our average market share of the international long distance market was approximately  60.3%, 58.4% and 54.9% in 2009, 2010 and 2011, respectively. Our market share decreased in 2011 primarily because of the intense  competition in the international telecommunications business, including a loss of business due to other VoIP providers and service  providers using unauthorized routers to carry long distance voice traffic. Our international long distance services consist primarily of  international direct dial services and our discounted “Super eCall” services, which we introduced in April 2000. Under Super eCall,  we use VoIP technology through international dedicated circuits which connect to our major correspondent carriers that route calls  internationally. Super eCall customers are offered rates that are approximately 30% lower than those for our international direct dial  service. Calls made over Super eCall represented 4.7%, 4.1% and 3.8% of our total outgoing international traffic in 2009, 2010 and  2011, respectively.  We commenced the wholesale of international long distance minutes to licensed international resale operators and other  international carriers in 2001. International resale operators require a fixed line operator in Taiwan to complete their long distance  telephone services originating in Taiwan. In addition, other international carriers often find it less expensive to route international  calls through Taiwan. These resale operators and carriers purchase from us large numbers of minutes at discounted rates. In 2009,  2010 and 2011, we sold 1,291.6 million, 1,360.0 million and 1,206 million of wholesale outgoing minutes, which represented  approximately 51.1%, 50.1% and 47.1% of our total outgoing international long distance minutes, respectively. Revenues from the  wholesale of international long distance minutes increased by 11.8% from NT$2,536 million in 2009 to 2,836 million in 2010, but  only increased by 3.2% from NT$2,836 million in 2010 to NT$2,927 million in 2011. We primarily attribute the decrease in the  growth rate to intensified market competition.
