Features
Programming the system may also involve using the dial pad, 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 Figure 30.

The red and green LEDs next to the 20 line and feature buttons assist the
system programmer. These buttons are on or off during programming,
depending on whether they have been programmed.
Direct Station Selector. One or two Direct Station Selectors (DSSs) can be
used with the MLX-20L telephone. Each DSS adds 50 buttons to the system
programming console. For more information about the DSS, see “Direct Station
Selector.”
The LEDs on the DSS indicate the status of telephone features during system
programming, such as Calling Restrictions. Each LED on the DSS represents a
telephone connected to the system. When certain features are selected from
the System Programming menu, the LEDs on the DSS indicate the status of the
feature for each telephone. For example, if Restriction is selected from the
Extension menu, the red LED is on for each telephone that is toll-restricted.
Programming with SPM on a PC
The advantages of programming the system with a PC are the availability of
surrogate mode and the security that comes from knowing that programming
can be backed up on a floppy or hard disk. This makes recovery of system
programming fast and efficient in the event of an inadvertent system shutdown
or loss of power. To program with a PC, the SPM software is needed, along with
