Configuring Dial Backup and Remote Management Through the
ISDN S/T Port
The Cisco 1812, Cisco 1801, Cisco 1802, and Cisco 1803 routers use the ISDN S/T port for dial backup
and remote management. Perform the following tasks to configure dial backup and remote management
through the ISDN S/T port of your router:
• Configure ISDN Settings
• Configure the Aggregator and ISDN Peer Router
Configure ISDN Settings
Note Traffic of interest must be present to activate the backup ISDN line by means of the backup interface and
floating static routes methods. Traffic of interest is not needed for the dialer watch to activate the backup
ISDN line.
