Note
1. Unit pulse price is defined by
Pulse Price
program.
2. Call duration is calculated by
CRL Time Filter
program.
3. Unit duration is defined by
Tariff Table
and
Time Table
programs.
4. The result of
GXUDWLRQ
8QLW
GXUDWLRQ
&DOO
is rounded up to the next higher integer.
IMPORTANT
Among the above described three methods, Method 1 is the most exact way to
calculate the cost of a call.
If there is
Polarity Reversal
facility on the lines, Method 2 can be used to calculate
exact starting time of the call, thus the exact call duration.
However, if Method 3 is to be used, the system calculates the cost approximately as
the
CRL Filter Time
can only make an estimation of call durations trying to detect
some C.O. tones.
The programs required for these three charging methods are explained in the
following pages.
I.1.
PULSE PRICE
(8778)
Allows defining a unit pulse price to serve the following purposes:
1. If there are real metering pulses on the C.O. line, the system can start detecting
these metering pulses and calculate the cost of the calls according to the
number of metering pulses received during the outgoing calls.
2. If there are no real metering pulses on the C.O. line, the system uses the unit
pulse price to calculate the cost of the outgoing calls using
Tariff Table
and
Time
Table
programs.
