Initial Feature Assignments for Non-attendant Voice Terminals
with 1520 Configuration in Standard Square Systems
Your system assigns your first eight lines
automatically to positions above the dial pad.
You must assign the remaining lines to the but-
tons to the right of the dial pad. The numbers
in the lower right-hand comer of each button
show the order in which lines are assigned to
buttons. If you don’t use a button for a line,
you can program a feature on the button.
