To configure ISDN interfaces on a J-series Services Router, you first configure the basic ISDN interface—either Adding an ISDN BRI Interface (Required) or Configuring Channelized T1/E1/ISDN PRI Interfaces for ISDN PRI Operation. Second, configure the dialer interface by performing Configuring Dialer Interfaces (Required).
To configure ISDN interfaces to back up primary Services Router interfaces, you then configure a backup method—either Configuring Dial Backup, Configuring Dialer Filters for Dial-on-Demand Routing Backup, or Configuring Dialer Watch.
To configure ISDN interfaces for dial-in or callback, configure the basic ISDN BRI or PRI interface and then perform Configuring Dial-In and Callback (Optional).
Perform other tasks as needed on your network.
