This command applies to the T1/E1 trunk resiliency feature. It allows you to force a resilient T1/E1 trunk to fail back immediately from the secondary controller to the primary controller.
If the primary controller fails, the resilient T1/E1 trunk is transferred to the secondary controller. After the primary controller returns to service, use this command to return support for the resilient T1/E1 trunk to the primary controller.
You must enter this command on the primary controller.
All calls in progress on the T1/E1 MMC card (PN 50005160) in the secondary controller are dropped when the system transfers support for the trunk back to the primary.
If the command is successful, the system displays a message indicating that the trunk has been transferred.
You will receive an error message if you enter this command
on the secondary controller
without specifying the physical location (PLID) of a T1/E1 Combo MMC card
before the primary controller has returned to service
You can only issue this command from the Maintenance Commands form of the System Administration Tool. You cannot enter this command from the telnet maintenance terminal (port 23).
The ALL qualifier applies the command to all resilient T1/E1 trunk circuits on the controller.
Notes:
Before you enter the EDT Force Failback command, use the State command to ensure that all the circuits are idle.
You can use the Programmed Failback command to schedule the resilient T1/E1 trunk to automatically fail back from the secondary.

If resiliency is not enabled for the trunk, the system response is
2005-11-18 11:00:27 EDT FORCE FAILBACK Failed, Resiliency not enabled.
If you do not enter the command from the primary controller, the system response is
2005-11-18 11:00:27 EDT FORCE FAILBACK Failed, must invoke from Primary Controller.
If the trunk is not connected to a T1/E1 Combo MMC, the system response is
2005-11-18 11:00:27 EDT FORCE FAILBACK Failed, T1E1 Combo Module required.
