DEFINING A SIM TO WORK BY CALL DURATION
In the Call Duration mode, each SIM works for a defined number of call minutes.
At the beginning of the day, the Gateway registers a SIM from the list and then counts down the
number of units defined for that SIM until it reaches 0.
The Gateway then registers the next SIM from the list. This process continues until all of the SIMs on
the list have finished their defined time units.
The Gateway resets the time unit count to the original definitions at the beginning of every month or
week, depending on the
Type
selected in the
Time Table
.
The calculation of the units per interval
The Gateway calculates the call duration by intervals. An interval is a minimum billing duration.
When making a call shorter than 1 interval, you will be charged the entire interval cost.
You must define the cost and time duration of the intervals.
Calculations are as follows (See the parameters in the figure above.):
At the beginning of the call the Gateway counts the units according to the
Primary bill interval.
The number of units for each interval are defined in
Primary Cost per billing interval.
This
Primary bill interval
is repeated according to the number of times defined in
Primary
Interval Count
.
The rest of the call uses the
Secondary Bill Interval
.
For example:
For a call of 1 minute and 59 seconds, the unit calculations are:
From the beginning of the call, two 30 second intervals (
Primary bill. int
) according to the
Primary Interval Count
for a total of 1 minute.
Each interval is 2 units according to the
Primary Cost per bill int.
definition.
Therefore, the charge calculation is: 2 intervals of 2 units per interval = 4 units
The remainder of the call takes 3 intervals of the
Secondary Bill Interval
for 59 secs.
Therefore, the charge calculation is: 3 intervals of 1 unit per interval = 3 units.
The total amount of units for this call will be 4 + 3 = 7 units.
Current Balance
The Current Balance is the number of units the SIM has left to use.
At the end of each call the unit count is updated. Once the Current Balance of a SIM has reached 0,
you will not be able to work again with that SIM until you set a new balance.
