3.Margin/Tax Rate Assignment
It is possible to add a margin (

Charge Tax [011]) to the call charges. The call charge rate per meter indication is programmable on a trunk group basis ( 
Charge Rate per Unit [012]).
[Calculation Method]
The margin or tax rate must be xx.xx % (whole number part: two digits, decimal fraction: two digits). A calculation method depends on the information which is sent from the telephone company: meter indication or charge.
a)Call charge with tax and margin in meter indication:
[Meter indication received from the telephone company] 
[Call Charge Rate]
[1 – Tax Rate] 
[1 – Margin Rate]
b)Call charge with tax and margin in charge:
[Charge received from the telephone company] 
[Call Charge Rate] [1 – Tax Rate] 
[1 – Margin Rate]
The calculation result is rounded up to the least significant decimal digit.
