AT&T 3.0 manual Persistent Module Problems, Busy-Out and Reset

Module Problems

Restoring automatically undoes the Busy-out and Reset. For additional information on restoring a module, see “Restore,” later inthis chapter.

Persistent Module Problems

If any of the module tests fail and replacing the module does not clear the trouble, then:

Several modules may be faulty.

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.

—In-progress calls are dropped if all of the calling parties on the call originate and terminate on the module being reset.

—If a call is using a line or extension on the module being Reset and another line and/or extension is involved in the call, the call on the module being reset is put on hold. In this case, the module can be removed and replaced. However, a demand test cannot be performed, because the module is not busied-out.

■Check the status of the reset module before performing a demand test.

Once you finish testing a module, you must restore it. Restoring a module terminates the Busy-out or Reset condition, See “Restore,” laterin this chapter, for instructions.
