• "Out Of Service": All fully configured trunks in the Trunk Group are out of service,
for example, when the Trunk Group is locked or in Busy Out state (see the
EnableBusyOut parameter).
Note: If the device is reset, a locked Trunk Group remains locked. If the device is
reset while graceful lock is in progress, the Trunk Group is forced to lock immediately
after the device finishes its reset.
