Expanding the phone system

Private lines

This feature allows you to set a private line (direct line) to the Line 4 jack of each unit. In this case, all 16 units can have their own private lines, and the connection of 16 units together adds up to a total of 19 telephone lines. The table below shows an example of how 16 extensions are connected to add up to 19 telephone lines.
