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.
