Introduction
Console Overlay
The programmable lines and buttons are on the main part of the console.
There are 20 physical buttons on the console itself but you can use the
overlay to program up to 34 lines. Some of the unlabeled buttons on the lower
part of the console may also be used for programming features. You can also
use the dialpad for entering feature and programming codes.
Figure 2 illustrates the system console overlay.
