CHAPTER 4. USING THE FEATURES

Facility Busy Indication

When the Facility Busy Indication feature is assigned to a button, the lamp associated with that Busy button provides a visible indication of the active/busy status of a particular trunk group or extension number. (The button is also labeled with the trunk group or extension being monitored.) The lamp is lighted when the facility is active or busy and is dark when the facility is idle; it flashes when an incoming call is received from the monitored extension number. The button can also be used for calling the monitored facility.

A Stored Number button may be used along with the Busy button to display the number of the facility being monitored. This display is accomplished by pressing the Stored Number button followed by the Busy button.
