Factors (Not in the USA) 
 


System Status | Call charges | Factors
 
Call charge factors per route can be configured under Factors. The accrued counting pulses are multiplied by the factors (price per counting pulse).

10.2.5.1  

Table: Call charge factors per route 
Call charge factors per route can be configured in this table.

Column: Multiplier  
The AOC information can be provided in call charge units or currency units. Both forms are supported, but only currency units are displayed. If the information is received in the form of call charge units, a conversion factor is used. This factor is configurable in order to make call charge adjustments possible or - if there are several network providers - to make an adjustment to the providers of the individual location. Even if currency units are provided, the conversion factor may prove useful for giving the display more clarity.
You can use the Multiplier column to define how received currency amounts are converted to call charge pulses (division of the currency amount by the multiplier), and how charges to be transmitted can be converted from call charge pulses to currency amounts (multiplication by the multiplier).

Column: Multi-ISDN  
The conversion factor is entered here. This parameter is only significant for routes (trunks) that use the CorNet-NQ and QSIG protocols.
You can use the Multi-ISDN column to define how received currency amounts are converted to call charge pulses (division of the currency amount by the Multi- ISDN), and how charges to be transmitted can be converted from call charge pulses to currency amounts (multiplication by the Multi- ISDN).

Column: Currency  
This parameter is only significant for routes (trunks) that use the CorNet-NQ and QSIG protocols. This parameter is not applied for other protocols. The preset default setting must be retained in such cases.
You can use the Currency column to define the currency string to be transmitted during transfer to the connected communication system (e.g. EUR). This must be adjusted in line with the connected communication system. If a currency string is not available, an empty string is transferred. This can be useful if call charge impulses are to be exchanged or if a standard currency is used.
Currency string configuration is independent of the currency string shown on the telephone display.

Column: charges  
This parameter is only significant for routes (trunks) that use the CorNet-NQ and QSIG protocols. This parameter is not applied for other protocols. The preset default setting must be retained in such cases.
You can use the charges column to define whether currency charges or call charge pulses are exchanged on the trunk. If this option is activated, the currency amount is sent and received (see the column Multi-ISDN). Otherwise, call charge pulses are sent and received. This must be adjusted in line with the connected communication system.
If call charge pulses are to be exchanged on the route, an empty string should be configured as the currency.

Column: Advice of charge  
This parameter is only significant for routes (trunks) that do not use either the CorNet-NQ or the QSIG protocol. In other words, it is only applied when the CorNet-NQ/QSIG network has been exited, e.g. for CO lines or CorNet-N lines.
You can use the Advice of charge column to define whether call charges should be transmitted to the CorNet-NQ/QSIG network, and under what conditions this should occur:
   -   No charges
No charges are received via this route (e.g. US CO lines)
   -   Interim
Charges are only received while the connection is active, and not during cleardown.
   -   Final
Charges are only received after the connection has been cleared down.
   -   Interim/Final
Charges are received while a connection is active and during connection cleardown.
For CorNet-N routes, advice of charge must be set to Interim/Final if a trunk call can be conducted via this route.

10.2.5.3  

Computing accuracy 
The Computing accuracy parameter should be configured so that the communication system's output and the currency totals transmitted by the ISDN CO have the same number of digits. If the maximum of three decimal points does not suffice, the figure is automatically rounded off.
The following values are possible:

Computing accuracy  
Minimum currency total possible  
Maximum currency total possible  
Via call charge pulse  
to be selected for routes (lines) with the protocols
CorNet-NQ and QSIG  
3 decimal points
(for example for the English Pound Sterling)  
1 x 10-3 = 0.001  
1 x 10-3 x (232 - 1) =
approx. 4.3 million  
2 decimal points  
1 x 10-2 = 0.01  
1 x 10-2 x (232 - 1) =
approx. 43 million  
1 decimal point  
1 x 10-1 = 0.1  
1 x 10-1 x (232 - 1) =
approx. 430 million  
No decimal points  
1 x 100 = 1  
1 x 100 x (232 - 1) =
approx. 4.3 billion
