The capability of the router to automatically establish connections to all desired remote sites and to 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 online minutes can be restricted to a specific period.
- For ISDN connections, a limit on time or charges can be set for a particular period.
