ISDN, MPLS and VSAT

We have a centralized database online system with hub and spoke network architecture. On top of this, we have our own VPN setup. Our users either connect through VSAT or dedicated leased lines for accessing our system with ISDN as a last mile backup connectivity. We are now exploring a possibility of having MPLS as a third option for our users and have some questions for you.

Is it possible to provide them ISDN as a last mile backup connectivity ? If yes, how does it works?

This will depend on the local service provider. The user would have to contact the provider to see if they can provide a BRI ISDN connection to the customer premises. If higher bandwidth is desired they could also check to see if the two B channels can be bonded together to create a larger pipe.
