A telecommunications carrier that provides both noncompetitive and competitive telecommunications services shall provide all noncompetitive telecommunications services on an unbundled basis to the same extent the Federal Communications Commission requires that carrier to unbundle the same services provided under its jurisdiction. The Illinois Commerce Commission may require additional unbundling of noncompetitive telecommunications services over which it has jurisdiction based on a determination, after notice and hearing, that additional unbundling is in the public interest and is consistent with the policy goals and other provisions of this Act.
