The backup is triggered when the monitoring mechanisms defined for the standard connection (LCP or ICMP polling) detect that contact to the remote site has been lost.
The backup connection will be established if:
- The backup delay time has expired and
- either
- a data packet is to be transferred or
- a hold time of 9999 seconds has been defined for the backup connection.
The backup delay time is set with LANconfig in the configuration area 'Communication' on the 'Call management' tab or alternatively with Telnet under /Setup/WAN-Modul/Backup-delay-seconds.
