System Programming
Initial system programming is done when the system is planned and installed.
The system can be reprogrammed as the needs of the customer change.
Like centralized telephone programming, system programming can be done
either on the system programming console or using SPM software.
Complete information on system programming can be found in System
Programming.
Programming with the MLX-20L Telephone
The MLX-20L telephone is the only telephone that can be used as a system
programming console (see Figure 29). The MLX-20L telephone must be
connected to the first station jack on the first MLX module for initial
programming of a new system.
For subsequent programming, the jack assignment can be changed. The
system operator jack can be used, or a separate system programming jack can
be designated to allow programming of the system without interfering with
system operator call handling.

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 Inspct.
The next five unlabeled buttons on each side are used to select options from a
menu displayed on the screen.
