GENERAL INFORMATION

FIGURE 2-1. Call Appearance/Feature Buttons
Associated with each call appearance/feature button is a pair of lights that provide information on
the availability and status of the appearance. These lights are described in the next part of this
manual (titled ‘‘Lights’’).
Any button that can be administered and is not used for a call appearance can be assigned to an
optional feature. Included in this category are buttons with two lights (call appearance/feature
buttons) and buttons with one or no lights, intended specifically for features. Some features
require light feedback to inform the terminal user when the feature is active; others are simple,
one-time operations for which light feedback would be meaningless. Good feature administration
matches features to appropriate buttons whenever possible.
