A cable operator shall file its rate justifications for the basic service tier and associated equipment with a franchising authority within 30 days of receiving written notification from the franchising authority that the franchising authority has been certified by the Commission to regulate rates for the basic service tier, or within 30 days from the date the franchising authority notifies the operator that the operator will be subject to the generally applicable rate rules because the operator's regulatory status has changed. Basic service tier filings for proposed rate increases and equipment rate filings for existing rates or proposed rate increases (including increases that result from reductions in the number of channels on a tier) must use the appropriate official FCC form, a copy thereof, or a copy generated by FCC software. Failure to file on the official FCC form, a copy thereof, or a copy generated by FCC software, may result in the imposition of sanctions specified in § 76.937(d). A cable operator shall include rate cards and channel line-ups with its filing and include an explanation of any discrepancy in the figures provided in these documents and its rate filing.
