P AR T I ●  international switch transmission equipment;  ●  network interfaces;  ●  directory equipment and services; and  ●  signaling network equipment.  Under the Administrative Rules for Network Interconnection, we, as a dominant telecommunication service provider  for fixed line and mobile services, are required to unbundle our network and provide cost-based interconnection charges  calculated with reference to the total element long-run incremental cost incurred by us. We are required to submit our  proposed calculations of the total element long-run incremental cost to the National Communications Commission, for its  approval each year. Local loop unbundling for both voice and data have been completed.  The Administrative Rules for Network Interconnection Between Telecommunication Service Providers was  further amended by the National Communications Commission on November 2011 specifying the charges for network  interconnection among Type I service providers as follow:  ●  Before January 1, 2011, except for international communications, tariffs for communications between a mobile  telecommunications network and a fixed-line network were collected from the call-originating subscribers by the call- originating service provider pursuant to the tariff schedules set by the mobile communication service provider, and  revenues or any uncollectible accounts from such tariffs went to the mobile service provider. However, from January  1, 2011, although the tariffs shall still be paid by the call-originating subscribers, the tariff schedules are set by the  call-originating network service provider, and revenues or any uncollectible accounts from such tariff shall go to the  call-originating service provider. During the transition period from January 1, 2011 to December 31, 2016, we, as a  dominant Type I fixed-line service provider, shall pay extra transition fee in addition to access charges to the mobile  communications service providers.  ●  Tariffs for communications between mobile telecommunications networks shall be paid by the call-originating  subscribers pursuant to the tariff schedules set by the call-originating service providers, and the revenues or any  uncollectible accounts from such tariffs shall go to the call-originating service providers.  ●  Tariffs for communications between fixed-line network will be determined by the following principles:  ●  tariffs for communications between the local telephone networks shall be paid by the call- originating  subscribers pursuant to the tariff schedules set forth by the call-originating service providers, and revenues or  any uncollectible accounts from such tariffs shall go to the call-originating service providers;  ●  tariffs schedules for the local telephone network subscribers using domestic long-distance telephone services  shall be set by the domestic long-distance telephone services provider and tariffs shall be collected from  the local telephone network subscribers using domestic long-distance telephone services. Revenues or any  uncollectible accounts from such tariffs shall go to the domestic long-distance telephone services providers;  and  ●  tariffs schedules for the local telephone network subscribers using international long-distance telephone  services shall be set by the international long-distance telephone services provider and collected from the  local telephone network subscribers using international long-distance telephone services. Revenues or any  uncollectible accounts from such tariffs shall go to the international long-distance telephone service providers.  61
