Outside line buttons
One or more of the buttons on your telephone may be
associated with either specific lines or outside line groups.
To access a line for dialing outside the system, press an
outside line button.
Floating buttons
Calls on outside lines for which no button has been
defined, may be associated with a button just for the dura-
tion of the call. These buttons are called "floating" buttons.
Some of the codes in your system may be different
from those indicated here. If so, see your System
