Private Lines
You can use the fourth line on each extension as a private line. A private
line is a telephone number assigned to just one extension.
NOTE: You must program the lines you are using at each extension
so that the phone knows which lines are shared and which are private.
(You can physically wire lines with different telephone numbers into each
unit for Line 4.)
The chart below shows 16 extensions, each sharing the first three lines.
