# THE CALENDER FUNCTION :
- Controlled by a Real Time Clock (RTC) that ishandled by the operating system of APZ thatincrements the clock.
- The Calender Function in APZ controls Time
differentiated charging by means of the Real TimeClock.
- Clock is used by the functions :
Charging (Time differentiated charging)
Routine Test
Traffic Recording

-Information about clock can be printed by command :
<CACLP;

Over a longer period of time, clock can start “Loosing” or
“Gaining”. This fact makes necessary to check and if
required, to adjust the clock at regular intervals.
However, the adjustment should not be more than a few
seconds over a time period of several months Clock
adjustment can be done by command:
CACLC:TDSF=5;
CACLC:TDSF=5,DATE=020510,TIME=0000;

The day categories (DCAT) are set according to the
requirement of the administration at the time of installation of
the exchange. Calender information can be printed bycommand CACAP.
- Day categories for a particular date being holiday
can be set by command :
- CACAS : DATE=020510,DCAT=2;
- For removal of day categories from the list, command
CACAR is used.
DAY CATEGORIES

There can 10 DCAT be defined in the system .
DCAT- 0 : Ordinary working day
DCAT- 1 : Day before holiday (e.g. Saturday)
DCAT- 2 : Holiday
DCAT- 3 to 9 : Spare

Charging Analysis – The Charging Case (CC)
- CHS consists of software only.
- For flexibility in the charging analysis, all data is stored
in tables which can be printed , modified by means of commands.
7/27/2019 Charging Analysis Axe
http://slidepdf.com/reader/full/charging-analysis-axe 13/34
CHARGING ANALYSIS :
- It is accomplished by means of several tables that deliver different analysis results.
- In the charging analysis, following things are analysed :
Who pays ?
Type of charging
Tariff to be applied for the particular call
Changing of tariff depending on type of day and time of day
Where the charging is to take place?
- Input to the Charging Analysis is the “Charging Case
- (CC)” – one of the result from B- Number Analysis table.

SPECIFICATION OF DATA FOR CHARGING ANALYSIS :
- Data specification for the Charging Analysis comprises of
following steps :
(1) Specification of Tariff (T) Data
(2) Specification of Switching Class (SWC) Data
(3) Specification of Tariff Class (TC) Data
(4) Specification of Charging Program (CHP) Data
(5) Specification of Charging Case (CC) Data
7/27/2019 Charging Analysis Axe
http://slidepdf.com/reader/full/charging-analysis-axe 16/34

<CHTSP:T=ALL; TARIFF DATA
T TDS NSP 1 0 2 1 3 180 2 4 1 1 5 1.200 1 6 1.600 1
7/27/2019 Charging Analysis Axe
http://slidepdf.com/reader/full/charging-analysis-axe 17/34
- The tariffs can be specified in the range 0.01 to
3276 seconds
- The tariff specification is done in the OP area
itself by using command CHTSI :
e.g. CHTSI :T= 24, NSP=1, TDS=90;

http://slidepdf.com/reader/full/charging-analysis-axe 18/34
(2) Specification of Switching Class (SWC)
Data :
-The Switching Class (SWC) is like a time table and there can
be up to 16 different time tables (SWCs) in the exchange for
time differentiated charging.
- The SWC Analysis table is divided into an Operating (OP) and
Non-operating (NOP) area in order to make it possible tochange the data during traffic handling.
- The Switching Class data table can be printed byusing command :
<CHSSP:SWC=ALL;

- Specification of SWC data (e.g. SWC=1) isaccomplished in the following steps :
CHSZI: SWC=1; (Clearing of NOP)
CHSPI:SWC=1; (Procedure initiation)
CHSSI:DCAT=0,TIME=0800&1400&2000;(Data specification)

(3) Specification of Tariff Class (TC) Data :
- In the Tariff Class (TC), the tariffs used during the dayare specified.
- The Tariff Class (TC) data table can be printed by usingcommand :

7/27/2019 Charging Analysis Axe
http://slidepdf.com/reader/full/charging-analysis-axe 23/34
- There can be up to 256 Tariff Classes in the exchange.
- When specifying a Tariff Class without any time
differentiated charging, no procedure has to be used as
one command is enough. E.g.
CHCSI:TC=1,T=1;
(Defining without swc)
7/27/2019 Charging Analysis Axe
http://slidepdf.com/reader/full/charging-analysis-axe 24/34
- However, if a Switching Class (SWC) is used in the
Tariff Class (TC), a procedure has to be used as under :
CHCZI:TC=4; (Clearing of NOP)
CHCPI:TC=4,SWC=1; (Procedure initiation)
CHCSI:DCAT=0,T=6&5&4; (Data specification)
CHCSI:DCAT=1,T=6&5;
CHCSI:DCAT=2&&9, T=4;
CHCPE; (Procedure end)
CHCAI:TC=12; (Transfer of data to OP)
CHCAR; (Reversion to old data)

(4)Specification of Charging Program (CHP) Data
- The Charging Program (CHP) contains information
about the :
Tariff Class (TC) Method of charging – PM or TT or both

A- party charging or B- party charging
Call Meter Alternative (CMA) etc.
7/27/2019 Charging Analysis Axe
http://slidepdf.com/reader/full/charging-analysis-axe 26/34
- CHP can be from 1 to 4095

following values :
CD= 0 Superior exchange is CP and CDP. Pulses
may be registered in own exchange.
CD=1 Reception of Tariff Messages
CD=2,3 Own exchange is CP & CDP
CD=4 Subordinate exchange is CP & CDP
CD=5 Own exchange is CDP and
subordinate exchange is CP

http://slidepdf.com/reader/full/charging-analysis-axe 32/34
- For a Charging Case (CC) without any branching, no
procedure has to be used as all the data can be specified in one
single command. E.g.
CHASI:CC=4,CHP=2;
- However for a Charging Case with branching condition, a
procedure has to be used as under :
CIBZI:CC=ALL; (Clearing of NOP)
CIBPI:CC=112; (Procedure initiation) CIBSI:BC=VPN-
0&CO-0,CHP=2003; (Data specification)
