mum 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, connec-
tions may be established to providers who do not transmit any charge
information!
13.3.2 Time dependent ISDN connection limit
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.
To reduce the costs of ISDN connections even if no call charge information is
available, maximum connection lengths based on time can be regulated. This
requires setting up a time budget for a specified period. In the router's default
state, for example, connections may only be established for a maximum of
210 minutes within six days.
When the limit of a budget is reached, all open connections that were
initiated by the router itself will be shut down automatically.The budg-
ets will not be reset to permit the establishment of connections until
the current period has elapsed. Needless to say, the administrator can
reset the budgets at any time if required!
The charge and time monitoring of the router functions can be disabled by
entering a budget of 0 units or 0 minutes.
Only the router functions are protected by the charge and time mon-
itoring functions! Connections via LANCAPI are not affected.
