When a call is transferred to an idle station, the bottom row of the idle
station's LCD will show the number of the line (L) that is being transferred,
followed by the word RINGING. The top row will show date and time.
After a preprogrammed length of time, if the station does not answer the
transferred call, the call will be re-routed to the Callback destination (see
Section 5, CALLBACK). The LCD of the Set receiving the Callback
notification will show the line number (L), followed by the words
RINGING BACK on the bottom row. The top row will show date and
time.
CAMP-ON DISPLAY
When a call is camped-on, the busy station's LCD will show the line
number (L) that is currently in use and the call time on the top row of the
display. The bottom row of the display will show the number of the line
that is camping-on (L), followed by the word CAMP.
C.O. LINE RINGING DISPLAY
The oldest ringing line is displayed on the bottom row of the LCD,
following the word RINGING and the initial "L", with the date and time
shown on the top row. Only one ringing line is displayed at a time.
Once connected, the line number moves to the top left of the display, and
the call timer starts timing the duration of the call. The call time appears on
the top right of the LCD.

When a conference is established, the lines and/or stations connected will be
