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.
NOTE:
To program a private line in a line group, press
E
to begin
feature setup and then select
SPECIAL
h
OPTIONS
. Enter the Line group
menu and select PRV to set the private line.
NOTE:
If the unit (extension) is not set to PRV, the Line 4 status
indicator will be unable to display a correct line status.
