6.11 Call charge management
The capability of the router to automatically establish connections to all
required remote sites and close them again when no longer required provides
users with extremely convenient access, e.g. to the Internet. However, quite
substantial costs may be incurred by data transfer over paid lines if the router
is not configured properly (e.g. in the filter configuration) or by excessive use
of the communications opportunities (e.g. extended surfing in the Internet).
To reduce these costs, the software provides various options:
The available ISDN connection charges can be restricted to a specific
period.
The available ISDN connection minutes can be restricted to a specific
period.
6.11.1 Charge-based ISDN connection limits
If charge information is sent to an ISDN connection, the resulting connection
charges can be limited quite easily. For example, in its default state, a
maximum of 830 charge units may be used in six days. The router will not
permit the establishment of any further connections once this limit has been
reached.
The best way to use the router's call charge monitoring function is if you have
“call charge information enabled
during the connection” to the ISDN
network (i.e. AOCD). If necessary, subscribe to this facility from your
telecommunications carrier. Charge monitoring with the “Charge information
after connection“ feature is also possible in principle, but in this case
continuous connections may not be detected!
If you have enabled least-cost routing on the router modules, connections
may be established to providers who do not transmit any charge information!
6.11.2 Time-dependent ISDN connection control
However, this mechanism of ISDN connection monitoring will not work if the
ISDN connection does not provide charge information. That may be the case,
for example, if the provision of charge information was not requested for the
connection, or if the telecommunications provider generally does not supply
this information.
