can ISDN be a backup for DSL

[kradjesh13]

Hi there,

Can ISDN act as a backup link for DSL line. If soo... can any one send me a document regarding this. At the moment my router is configured with DSL is up and running. I don't have any clear idea how to configure a backup link on top of this.

So, it will be a great help if some one comes us with some of the document regarding this.

Thank you

Rajesh
