"Telecommunications service" means the provision or offering for rent, sale or lease, or in exchange for other value received, of the transmittal of information, by means of electromagnetic, including light, transmission with or without benefit of any closed transmission medium, including all instrumentalities, facilities, apparatus, and services (including the collection, storage, forwarding, switching, and delivery of such information) used to provide such transmission and also includes access and interconnection arrangements and services.
"Telecommunications service" does not include, however:
The Commission may, by rulemaking, exclude (1) private line service which is not directly or indirectly used for the origination or termination of switched telecommunications service, (2) cellular radio service, (3) high-speed point-to-point data transmission at or above 9.6 kilobits, or (4) the provision of telecommunications service by a company or person otherwise subject to Section 13-202 (c) to a telecommunications carrier, which is incidental to the provision of service subject to Section 13-202 (c), from active regulatory oversight to the extent it finds, after notice, hearing and comment that such exclusion is consistent with the public interest and the purposes and policies of this Article. To the extent that the Commission has excluded cellular radio service from active regulatory oversight for any provider of cellular radio service in this State pursuant to this Section, the Commission shall exclude all other providers of cellular radio service in the State from active regulatory oversight without an additional rulemaking proceeding where there are 2 or more certified providers of cellular radio service in a geographic area.
