ADSL with ISDN Backup

[rich2003]

Hi All,

I have a Cisco 1721 Router with a ADSL WIC card which I used to connect to my ISP. This works fine, and IP traffic passes ok.

I also have a ISDN BRI WIC installed (in the same router) and I need to get this to dial a ISDN number when the ADSL connection fails.

Can this be done?
Is it similar to the dial backup for serial lines?

Hope someone can help / has already done this.

Thanks.

Rich.

It is almost the same. Here you have an example:
