isdn backup for mpls-vpn's

Is there any documentation-solution (or even configuration)for a PE-NAS(?)-CE (MPLS VPN) scenario with a leased line and isdn backup,from the PE point of view?

Assuming that i use a NAS connected via eth. to the PE,for the CE to PE backup calls

and the leased line terminating to the PE do i have to configure any GRE tunnel between the CE and PE through the NAS for the ISDN call?

Thanks in advance,
