All,



I have a hub and spoke network. At the central location, I have a
frame-relay router and a seperate isdn router. And the remote sites each
have the same.



My DDR will turn on when the frame connection at the remote site fails,
causing the remote site router dial the central location. The issue resides
when the frame connection comes back up. The DDR will not shut off.



Here is the DDR config at the central and remote site.
