A programmed Automatic End of Billing occurs at midnight.
More than one End of Billing request may occur at the same time (for example, a deferred tariff
introduced at the start of a new season), but only a single End of Billing event will take place. The
cause of each of the End of Billing events is recorded but the End of Billing Counter is only
incremented by one.
If an automatic End of Billing event should have occurred during a power down, then a billing
event will take place immediately following the next power up. If several requests were missed
then a single billing event is created, the cause reflecting all billing events that were missed.
If an End of Billing reset is required when the current tariff is manually overwritten by a new
current tariff, it should be manually requested as part of the communications session.
