connection (RJ-11) on the side of the KSU.  
This feature is available for use with single line telephones.

Privacy release can only occur for external lines within the same tenant group.  If a
call is transferred to another tenant group, privacy cannot be released.  
Privacy on all calls is the default setting when the system is initially installed.  
The Barge-In feature can be used to access a telephone line that does not have
privacy released.  If Barge-In is enabled in system programming, it overrides the
privacy assignment.  [Refer to  Barge-In (Interrupting an External Call) on page 3-20.]
Privacy on all calls a can be released by individual users by pressing     
while on an external call.  If      are pressed again, privacy release is
canceled.

up or presses hookflash.  
LCD indication for privacy release is the same as the display for an add-on
conference on an external line.
The       LED flashes red on the telephone where privacy is released and lights solid
red on the  
   LED on the telephone that picks up the line.  
A single line telephone can access an external line that has privacy released by
dialing
