Digital Display Module
Display
A vacuum-fluorescent 40-character alphanumeric display that presents numerical digits, upper-
case and lowercase letters, and punctuation marks.
On/Off Switch
The On/Off switch turns the module on and off. The associated green status light goes on when
the module is on and is dark when the module is off.
Assignable Function Buttons
Seven additional buttons with associated green status lights. The System Manager assigns
these buttons to display the control functions.
Display Functions
The following display functions are available on buttons (the actual labeling on some buttons is
shortened). If more than seven buttons are required, the additional buttons may be assigned on
the associated voice terminal.
Normal Mode—used to place the display in the Normal mode. In this mode, the display
provides call-related information automatically.
Inspect Mode—used to place the display in the Inspect mode to permit the user to see
caller identification on an incoming or held call while active on another call.
Message Retrieval—used to place the display in the Message Retrieval mode. This
mode is used to retrieve messages for the voice terminal on which the module is
mounted.
Coverage Message Retrieval—used to place the display in the Coverage Message
Retrieval mode. This mode is used by coverage agents to retrieve messages for other
terminals.
Next—used in Message Retrieval mode to step from one message to the next; also used
in the Integrated Directory feature to display the next name (except on System 85 or
DEFINITY G2).
Delete Message—used in Message Retrieval mode to delete messages.
Make Call—used in Message Retrieval mode to automatically initiate a call to the caller
identified by the last displayed message (for internal calls only); also used to automati-
cally call internal extension numbers displayed by the Integrated Directory feature
(except on System 85 or DEFINITY G2).
Integrated Directory (except on System 85 or DEFINITY G2)—used to place the display
in the Integrated Directory mode. In this mode, the system directory can be searched by
entering the desired name with the dial pad, and names with their corresponding exten-
sion numbers will be displayed.
