Programming Overview

System Programming Console

The system programming console is an MLX-20L telephone connected to the
system programming jack. When you enter system programming on a new
system for the first time, the console must be connected to the first jack on the
first 008 MLX module or 408 GS/LS-MLX module (Release 2.0 and later
versions). This jack is factory set as the system programming jack and as an
operator position. After you enter programming, you can change the system
programming jack to anyone of the first five jacks on the first 008 MLX module
or 408 GS/LS-MLX module (Release 2.0 and later versions). This allows you to
program without interfering with the operator's call handling.
You can also have one or two Direct Station Selectors (DSSs) connected to the
system programming console. Each DSS adds 50 extension buttons to the
console, which facilitates assigning features to telephones.
The MLX-20L telephone with a DSS is shown in Figure 1-1.
