OTES
The system uses the CRL Time Filter to detect the starting time of the outgoing
external calls in the following way:
After an extension dials an external number, the system tries to detect the
starting time of the call by checking the C.O. tones, i.e. ring-back, busy or
overflow tone. After detecting such a tone, the system tries to detect the
approximate time when this tone stops and uses this time as the starting time of
the call.
If the system cannot detect a valid tone within the CRL Time Filter , it starts to
record the call as “Starting time
=
Line access time + CRL Time Filter ”.
I.4. TARIFF TABLE (8023)
Allows preparing a Tariff Table for charging the outgoing calls.

P = 1 : The tariff for local calls is developed.
= 2 : The tariff for long distance calls is developed.
= 3 : The tariff for international calls is developed.
Q = 0 : The standard tariff is developed.
= 1 : The economical tariff is developed.
R = 001,…,250 : The unit duration (in seconds) which the
system uses to charge calls.

Using this program, a table which can be simply figured as below can be
formed:
Standard Tariff Economical Tariff
Local Calls R

Long Distance Calls R

International Calls R

While calculating the cost of calls, the system decides to use Standard or
Economical Tariff by comparing the starting time of the call with parameters of
Time Table
program. (See
Time Table
program as well.)
