ISDN backup for a T1 connection

I have a Cisco 1760 router at my remote site and a 1760 at H.Q via T1. What i would like to do is install a backup isdn card at the remote site and have it dial into an AS5300 router that i have at HQ if the T1 line goes down. Could this be done? or do i have to install an isdn wic at the remote 1760 as well as the 1760 at HQ?

any links would help

Thanks,

Re: ISDN backup for a T1 connection

You could do either ways. Its just a matter of setting up the dial backup strategy and routing tables
