Using AUX ddr to back aDSL

Has anyone tried to use the AUX port to backup a aDSL link using DDR.

I know this works with backing up ISDN and Serial lines using the dialer watch feature but want to know if I can do the same with the aDSL connection

Re: Using AUX ddr to back aDSL

In case of ADSL line, the atm interface will be up/up once cpe is trained. so backup command and floating static routes will not work here..In that case you need to configure the "dialer watch" (watching for a advertised route) so that router can determine about the layer 3 status of the dsl line to activate aux port..Thanks..Tejal
