Local Display Functions 2 - 6 - AT&T SYSTEM 25 Manual

This feature applies to display voice terminals only.
The Local Display feature allows the user to operate the Time/Timer circuit built into the
display module. The voice terminal must be in the "Local Mode" for use of Local Display.
The Timer has Set, Start, Fwd (Forward), Stop, Rev (Reverse), Time/Timer, and Exit buttons
to control the visible clock, calendar, and 60-minute timer displays and an audible alarm.
Some terminals are equipped with a LOCAL button for entering and exiting Local Mode.
Local Display operation depends on the functional assignment and administration of the
voice terminal. For a general use station, the LOCAL button is optional. The LOCAL button
is a fixed feature on the SLAC.
Logged-In DGC Station or Switched Loop Attendant Console
At a Switched Loop Attendant Console or DGC terminal that is logged into its group, Local
Mode is normally off. During idle periods, the queue (Attendant or DGC) count is displayed.
The user can press LOCAL, if equipped, or Time/Timer to override the queue count and
activate Local Display. Any change in queue count or new call-handling activity, returns the
terminal to Normal Mode. When active on a call, the user can go to Local Mode by pressing
Time/Timer and return to Normal Mode by pressing the active call appearance button.
If the terminal has a LOCAL button, it can be used to exit and enter Local Mode.
At SLACS and logged-in DGC terminals, preference is given to queue
NOTE:
displays over the clock/calendar display. This condition can be overridden by
pressing LOCAL, if available.
General Use or Not-Logged-In DGC Station
When the terminal is idle, Local Mode is automatically on and either the Clock/Calendar or
Timer screen is displayed. Any call-handling activity (such as a ringing call or going off-
hook) overrides Local Mode and displays the appropriate Normal Mode data. During Normal
Mode activity, the user can manually return to Local Mode (for example, to find out what
time it is or to time a call) by pressing Time/Timer; to return from this condition to Normal
Mode, the user presses the active call appearance button. When the call activity ends and the
user goes on-hook again, the terminal reverts to Local Mode.
If the terminal has a LOCAL button, it can be used to turn off Local Mode; during idle
periods in this condition, the screen remains completely blank. To return to Local Mode,
the LOCAL button must be pressed again.
