DURATION AND COST
Duration
The system counts two types of duration:
- Duration of the communication: this corresponds to the time during which the system considers that
a line is allocated to a subscriber; this accounting occurs after the first switch to conversation mode
by the subscriber with the line.
- Call phase duration: the system counts the call phase duration of an incoming external communi-
cation from the moment when the system detects the call to when the line changes to conversation
with a system terminal. This information is used during external management.
Cost
The cost of a communication is calculated according to the number of units charged:
- The value of the basic metering unit may be constant, regardless of the length of the communica-
tion.
- The value of the basic metering unit may be variable: the cost of the first x metering units is calcu-
lated according to an initial basic metering unit value. As soon as a threshold number of metering
units is reached, the cost is calculated according to a second metering unit value.
Notas :
The software allows the actual duration of the communication to be shown on the metering ticket:
- on receipt of a CONNECT message on digital networks
- on receipt of a polarity inversion or a metering pulse on analog networks.
In all other cases, the duration given is only approximate since it is calculated by an off-hook simulation
mechanism.
Useful parameters for calculating the cost of a communication:
T Value of the basic metering unit before reaching the configured threshold (6 digits in the chosen
monetary unit, of which 0 to 2 are decimals)
T Threshold for using the second basic metering unit value (in metering numbers from 0 to 99)
