Conventions Used in This Manual
The following conventions for discussing configuration points
for the Carrier Controller display will be used in this manual.
The menu items are shown in this document as they appear on
the Carrier Controller display. A path name for each item will
show the user how to navigate through the Carrier Controller
display to reach the desired configuration. The arrow symbol
() in the path name represents touching the menu item on the
screen of the Carrier Controller display. The path will be
shown in bold and italics. See Appendix A for a complete list
of Carrier Controller menu items and descriptions. The Carrier
