ISDN query

Is it possible to configure a 1721 router to enable a second BRI interface to come up should active interface go down, as a contingency option?

Thanks in anticipation.

Yes, try the resources for backup interface and Dial on demand routing .I use DDR but it depends on the network infrastructure
