A system feature provides automatic 
privacy on all lines at-every 
station. Automatic privacy prevents other stations from jolnlng 
a station on an active line unless that station user allows it. 
Through programming, the system can be configured so that certain 
lines are normally non-private. When the non-private line is in 
use at a particular station, users of other stations in the m 
system can join that station user on the non-private line. This 
can be accomplished by...

The system programming is electronically protected during an 
AC 
power failure by a battery-like device called a super-cap. The 
stored program data will remain in memory for a minimum of 30 
hours after AC power fails or is disconnected. The system must 
be powered continuously for at least 30 minutes prior to the 
power failure or disconnection for memory preservation to occtir.
