Significant market powers shall, in sequence, adopt technical specifications prescribed by the competent authority, national standards, international standards or interconnection terms and conditions for existing telecommunications systems, which shall be the installation standards for signaling, transmission, synchronization, traffic volume or necessary traffic data exchanges functions.
In absence of the standards set forth in the preceding paragraph, it shall be determined between significant market powers and other telecommunications enterprises through negotiation.

The interconnection-related charges include interconnection setup charge, termination rate, transit charge, connection charge or other equipment rents, and other ancillary charges.
The charges incurred from the network interconnection between significant market powers and other telecommunications enterprises shall be handled as follows:
1. The termination rate and connection charge shall be assumed by the party that receives the tariff; nevertheless, specific agreement follows if there is any negotiation with the connection charge by the interconnecting enterprises.
2. The transit charge shall be assumed by the party that leads to the reason for the switching, and it shall be determined through negotiation if there is no reason for the switching.
3. Other costs shall be assumed by the party that requires interconnection and results in the cost increase of the other party.
