Configuring ISDN Interfaces 107
on each interface. For more information, refer to Chapter 14, "Configu-
ration Interdependencies".
11a. Check the time restrictions for the Interface Status .
In this window you can determine the days and times
during which the given interface can be used. Outside these
periods, the interface is barred for outgoing as well as
incoming calls. The interface status in the ISDN Console
changes from UP to DOWN to indicate that outgoing calls
are not possible and incoming calls to this interface are
rejected. A connection configured as a backup router would
then be activated.
When the Interface Status changes from Enabled to Disa-
bled, all active connections over this interface are cleared.
For example, you can disable the Interface Status during the
weekends to make sure that no one is able to dial into or out
of your LAN.
11b.Check the time restrictions for Inbound Call Processing .
Here you can define the days and times during which
Inbound Call Processing is enabled (asterisk) and disabled
(no asterisk).
When the value changes from Enabled to Disabled, active
connections will not be affected.
11c. Check the time restrictions for Outbound Call Process-
ing .
Here you can define the days and times during which
Outbound Call Processing is enabled (asterisk) and disabled
(no asterisk).
When the value changes from Enabled to Disabled, active
connections will not be affected.
12. If you are using an AVM ISDN-Controller for PRI, check the
Setup Delay .
In some rare cases local exchanges have problems with multiple
call set-ups within short intervals at Primary Rate Interfaces.
If this is the case, define the Setup Delay in milliseconds.
