Whenever the commission finds that public convenience and necessity require the interconnection of the radio communications facilities of a certificated radio common carrier with the telephone facilities of a land line telephone utility serving all or part of the certificated territory of the radio common carrier, and that such common carrier and land line telephone utility have failed to agree upon such interconnection or the terms and conditions or compensation for the same, the commission may, upon petition of either party, order that such interconnection be permitted, and prescribe a reasonable compensation and reasonable terms and conditions for such interconnection.
