The buttons next to the console's display are used to do most of the
programming. The top two buttons on each side are labeled and have the same
functions in every screen. They are Home, Menu, More, and Inspect.
The next five unlabeled buttons on each side are used to select options from a
menu displayed on the screen.
Programming the system may also involve using the dialpad, some of the
labeled function buttons on the lower portion of the console, or the 20 line and
feature buttons in the center of the console. The overlay that "renames" buttons
for use during programming is shown in Appendix E.
The red and green LEDs next to the 20 line and feature buttons assist you in
programming the system. They will be on or off, depending on whether or not
the line has been programmed.
One or two direct station selectors (DSSs) can be used with the MLX20L
telephone. Each DSS adds 50 buttons to the system programming console. See
"Direct Station Selector" in this chapter for a complete description of the DSS.
The LEDs on the DSS indicate the status of telephone features, such as Dialing
Restrictions. Each LED on the DSS represents a telephone connected to the
system.
When certain features are selected from the menu, the LEDs on the DSS
indicate the status of the feature for each telephone. For example, if Restriction
is selected from the Extensions menu, the red LED is on for each telephone that
is toll-restricted.
