Under Saprang 's leadership , TOT reaffirmed its ownership rights to all existing backbone telecommunications networks under a new strategy to act as a " genuine " national telecom company . The new strategy was expected to increase political and business tensions . Under the Build @-@ Transfer @-@ Operate ( BTO ) concession agreements that TOT signed with private telecom operators , the TOT technically own all fixed @-@ line , mobile , and optical fibre networks in Thailand . However , it had never exercised those rights in the past .
