ISDN Dial Backup
Setup

This setting is available for the routers supporting ISDN function
only. Before utilizing the ISDN dial backup feature, you must
create a dial backup profile first. Please click Internet Access
Setup > Dialing to a Single ISP to enter the backup profile.

Due to the absence of the ISDN interface in some models (e.g.,
Vigor2900V and Vigor2900VG), the ISDN dial backup feature and
its associated setup options are not available to them. Please refer to
the previous part for further information.
None - Disable the backup function.
Packet Trigger -The backup line is not on until a packet from a
local host triggers the router to establish a connection.
Always On - If the broadband connection is no longer available, the
backup line will be activated automatically and always on until the
broadband connection is restored. We recommend you to enable this
feature if you host a web server for your customers’ access.

Keep WAN
Connection

Normally, this function is designed for Dynamic IP environments
because some ISPs will drop connections if there is no traffic
within certain periods of time. Check Enable PING to keep alive
box to activate this function.
PING to the IP - If you enable the PING function, please specify
the IP address for the system to PING it for keeping alive.
