the relevant Type I service provider in providing the universal services. All providers of universal services cannot refuse any  request for service, unless for legitimate reasons, and cannot charge more than the predetermined tariffs.  As a result of the liberalization of Taiwan’s telecommunications industry, a Type I service provider, including a  3G mobile services provider and a WiMax service operator, is required to provide its customers with equal access to the  domestic and international long distance telephone services provided by other service providers. A Type I service provider  may provide equal access through pre-selection or call-by-call selection. Before July 1, 2005, all Type I service providers,  including us, provide equal access only through call-by-call selection. When a customer makes a call using call-by-call  selection, such customer has the option to select a service provider by dialing the network identification prefix assigned to the  service provider of his choice. This will result in the automatic selection of the preferred service provider for the provision  of relevant telecommunication services. Starting from July 1, 2005, all Type I service providers also provide equal access  through pre-selection in Keelung City, Taipei City/ County, Taichung City/County and Kaohsiung City/County. Equal access  through pre-selection is available throughout Taiwan since January 1, 2006. The pre-selection function allows any customer  to select in advance a long distance or international service provider of his or her choice. When such customer makes a call  using this function, the communications network will automatically interconnect to the long distance or international network  previously selected by such customer.  According to the Telecommunications Act and the Administration Rules Governing Number Portability, Type I  service providers shall provide number portability service which enables customers to retain their existing local and toll free  fixed line telephone numbers or mobile phone numbers when they switch from the original Type I service provider to other  Type I service provider. Meanwhile, Type I service providers shall mutually grant each other number portability services on  a reciprocal basis, and shall conform in accordance with the principle of impartiality and reasonableness, and shall not be  discriminatory.  Under the regulation, we are required to provide number portability service for fixed line customers in Taipei City,  New Taipei City, Keelung City, Taichung City, Kaohsiung City and other areas where there are two or above fixed line service  providers. We have also provided number portability service for mobile communication customers since October 15, 2005.  Pursuant to the regulation, we shall compile and submit related information of number portability for the previous six months  to NCC by January 10 and July 10 of each year.  In December 2006, the National Communications Commission defined the local loop as facilities “at the bottleneck  of telecommunications networks” in accordance with the Regulations Governing Fixed Network Telecommunications  Businesses. The National Communications Commission requires us to unbundle the local loops and allow other  telecommunications operators to use these connections. The local loop or last mile connections are the physical wire  connections between the telephone exchange’s central office to the customer’s premises usually owned by the incumbent  telephone company. The National Communications Commission further amended the “Administrative Rules for Network  Interconnection between Telecommunication Service Providers” in April 2007 which provides that we can only charge other  local telephone service providers at cost for local loop services instead of on the basis of commercial negotiations.  We have been declared by the former competent authority Ministry of Transportation and Communications as a  dominant Type I service provider for fixed line and mobile services.
