Advanced ISDN parameters

These are the advanced settings for the ISDN interface.
Metric:
This parameter specifies the connected metric of the mobile interface. The default metric of a
connected interface is 1. By allowing the interface to have a higher value (lower priority), static
routes can take preference to interfaces. For normal operation, leave this value unchanged.
Enable "Always On" mode of this interface
On
This parameter configures the PPP instance so that if the unit is disconnected, it tries to
reconnect again after approximately 10 seconds or dictated by the Configuration - Network
> IP Routing/Forwarding > IP Routing > When an "Always On" route becomes "In
Service", wait n seconds before using it parameter.
On and return to service immediately
This is similar to the above parameter. If you enable this parameter, but the unit will try and
connect immediately and without delay.
Put this interface "Out of Service" when an always-on connection attempt fails
Usually, the always-on interfaces do not go out of service unless they have connected at least
once. When this option is turned On, the interface goes out of service even if the first
connection attempt fails.
Attempt to re-connect after n seconds
This parameter specifies the length of time in seconds that the unit will wait after an always-
on ISDN connection has been terminated before trying to re-establish the link.
