[c-nsp] Dial Backup

[Montes, Carlos M]

To all, I have a question about dial backup.  If you don't mind I need your help.  I have a 2600 with a Frame Relay circuit that's backed up by a Serial Interface that is working as an ASYNC interface with the appropriate command.  The Interface is then connected to a modem.  The backup works great as designed, however when the phone line is down the router is not able to detect the problem.  I did some testing of the backup yesterday and found out the backup phone line was dead.  

Is there any way that I can ensure that the phone line is available?


Thanks
