Restoring automatically undoes the busy-out and reset. For additional
information about restoring a module, see
Persistent Module Problems
If any of the module tests fail and replacing the module does not clear the
trouble, then either several modules may be faulty or the connector on the
carrier may be faulty.
Busy-Out and Reset
Before running any module test, be sure to busy-out or reset the module.
Busy-out discontinues service from the module being tested to each line
and extension only as they become idle. Busy-out is the preferred
method, because it does not disrupt calls in progress.
Reset discontinues service to all lines and extensions on the module
instantly.
