Okla. Admin. Code § 165:55-5-2
Except as provided in OAC 165:55-5-1, every telecommunications service provider shall file with the Commission its tariffs containing detailed schedules of its rates and charges for all intrastate regulated telecommunications services. The tariffs shall be in sufficient detail and shall be accompanied by such explanatory material, so as to permit determination of the applicability of the tariff. For standard services, the tariff should be structured to permit determination of the exact charges from the tariffs alone. Services, whose rates and charges are determined on an individual case basis, need not indicate the exact charges in the tariff. Related provisions, such as the circumstances under which services are available, classes of service offered, and line extension policy, will be set out in the tariff or by reference to other filed tariffs. Unless provided otherwise in this Chapter, no tariff shall be effective except by order of the Commission or otherwise pursuant to the laws of the State of Oklahoma.
