Matrix NAVAN CNX200 System Manual 623
• This Pulse Rate type obtained from the Area Code Table is checked in the Pulse Rate table to obtain
the corresponding duration and cost to be applied for the call duration. The Pulse Rate Table may be the
Normal Pulse Rate Table or Discounted Pulse Rate Table, depending on the day of the call. The
system uses the built-in RTC to determine the day.
• The Pulse Rate Type applied (duration and cost) is divided into two parts for each time zone:
• First unit.
• Additional units.
• Number of Units is derived from the pulse rate at the time of the call and duration of the call. System
acquires the pulse rate type and call duration with the help of in-built RTC.
Total Units = First Unit + Additional Unit.
If the call duration is less than the pulse rate of the first unit then additional unit is zero.
Call Units = (Call duration in seconds) (Pulse rate in seconds).
• If the duration of the call is less than or equal to one unit,
Cost of Call = Cost of First Unit + Service Charge as applied.
• If the duration of the call is more than one unit,
Cost of Call = [Cost of First Unit + (Number of Additional units x Cost for Additional units)] + Service
Charge a
s applied.
• The system applies the rates as configured in the Normal Pulse Rate Table for all the days, except when it
detects a day configured in the Discounted Pulse Rate Schedule. These are special days when special
tariffs are offered.
For the days configured in the Discounted Pulse Rate Schedule as special days, the system checks the
duration and cost of the First unit and the Additional units configured in the Discounted Pulse Rate Table.
NAVAN uses the Cost of the Call for SMDR and also to deduct it from the Call Budget (Amount), if allotted to the
trunk.
The logic for call cost calculation is explained by following example:
• An Outgoing Call is made on trunk, CO-1.
• On CO-1, Call Cost Calculation is configured as follows:
• Call Cost Calculation Pulse Rate option = 1
• Call Cost Calculation Schedule,
• Time Zone 1 = Start Time: 00:00, End Time: 22:00
• Time Zone 2 = Start Time: 22:01, End Time: 23:59
