Official Gazette-Issue 41- Addendum - 23/7/2002 in the event of undue billing or other disputes or claims related to bills or service provision. 3) The TRA may monitor and regulate the rates and tariffs of all public Telecommunications Services by any means it deems appropriate, such as by issuing regulations, including conditions in the License document, or conducting an accounting of operational costs and revenues. In the interest of consumer protection, the TRA may impose prices and tariffs on Service Providers if it becomes aware of monopoly pricing or of a situation that enables monopoly pricing. 4) All Public Telecommunications Services Providers shall offer their services pursuant to the prices and tariffs notified to the TRA. Such prices, tariffs or other terms of service shall not be changed without prior notification to the TRA and provided that the TRA does not object to such changes in a motivated decision issued within 60 days. The silence of the TRA, by the end of the period mentioned in the previous paragraph, is deemed an implicit approval of the new prices and tariffs. Article 29: Interconnection 1) All Service Providers with Significant Market Power shall establish Interconnection with other Service Providers for the transmission and receipt of data, provide the necessary facilities and arrangements for that purpose, and establish and apportion the charges thereof, pursuant to the conditions set by the TRA. 2) Interconnection among Service Providers shall be established by agreement within a maximum period specified by the TRA. In the event that Public Telecommunications Services Providers fail to agree on terms of Interconnection within the maximum period specified by the TRA, the TRA may, at its own initiative, impose Interconnection terms pursuant to its own rules and requirements. The TRA shall publish, at the expense of the concerned parties, a summary of the basic terms of the Interconnection agreements in the Official Gazette and in two local newspapers. 3) The TRA may approve or impose amendment to the provisions relating to Interconnection between Public Telecommunications Services Providers authorized by foreign countries in accordance with the international accounting rate framework, including the accounting rates and settlement arrangements agreed upon by the concerned parties before the agreement becomes effective. 19
