preference. If they are unavailable, the system will chose the last line used at the station.
If it is busy, no further choice is made. No class of service is required.

LCD Messaging
Standard and system-supplied custom display messages can be set by dialing a specific
code at any station. Such messages are to be received and displayed by any LCD
speakerphone that calls the station which set the message. When a message is set, the
intercom light at the setting station will flash to indicate that the feature is active.

LCD Support
The system supports the use of digital telephones having a Liquid Crystal Display
(LCD). The display is capable of providing the station user with a visual presentation of:
call cost, call duration, number dialed, name of called station, name of active feature,
date and time, and programming prompts.
Interactive Button Support
The LCD speakerphone provides the user with three interactive buttons and expanded
LCD displays as a standard feature. The interactive buttons provide the user with quick,
easy access to system features and straightforward button programming without dialing
codes. The expanded displays prompt the telephone user on the operation and progress of
many of the telephone features and provides designations for the interactive buttons.
Since the interactive buttons provide many user features, their immediate functions vary
with the feature. The button functions change to match the feature that the user is
currently operating. At any given time, the current button designations show in the
display window.
Button Query
Station users who have LCD speakerphones can use their interactive buttons to access the
button query feature. With this feature, the station user can cause his or her LCD
speakerphone to show the function of each of its buttons on its display.
