If end users of an intrastate service that uses local switching facilities pay message unit charges for such calls, a credit is deducted from the local switching element charges to the carrier. The per minute credit is multiplied by the monthly access minutes for the service to compute the monthly credit.
If all local exchange subscribers pay message unit charges, the per minute credit is computed by dividing total message unit charges to all subscribers in a representative month by the total minutes of use that were measured for purposes of computing message unit charges in that month.
If some local exchange subscribers pay message unit charges and some do not, a per minute credit is computed by multiplying a credit computed according to the second paragraph of this section by a factor that is equal to total minutes measured in a representative month for purposes of computing message unit charges divided by the total local exchange minutes in that month.
