A carrier's carrier's or association's charges are computed and assessed on a party that uses local exchange switching facilities for the provision of intrastate telecommunications services. Intrastate switched access charges are billed monthly. However, if the cost of billing exceeds the amount of the bill the company may, with the concurrence of the customer, bill on a less frequent basis such as quarterly, semiannually, or annually.
