It is true that the Ethernet interface of the router will show as up/up when connected to the DSL modem even if it has lost the ability to communicate through the DSL modem. There are a couple of ways to get around this, depending on how you have configured your backup. Many people have successfully implemented Reliable Static Routing Backup Using Object Tracking to deal with this issue. This link will give you information about how to configure this and how it works:

If this does not seem an appropriate solution to your situation then perhaps you can give us some detail about your situation and what you have set up.
