System Programming
Console Overlay
The MERLIN LEGEND Communications System can be
programmed from either an MLX-20L telephone used as a
system programming console or from a PC with System
Programming & Maintenance (SPM) software.
Using a system programming console may involve the dialpad,
some of the labeled function buttons on the lower part of the
console, and the 20 line and feature buttons in the center of the
console. The programming functions of the line and feature
buttons are on the overlay for the console, as shown in
Figure H-1.
