When an auto-answer connection is established, an event is registered in the
Auto
Answer
dialog box, as shown below, and logged in the auto-answer log file (see
Auto-
answer Configuration
).

by the operator. During this time, the operator can view the controllers and determine the
cause of the alarm. The status bar will also display a countdown of the remaining
connection time in seconds.
