The system supports the day,night and lunch operation modes. The system operation for
making and receiving calls can be different for the day,night and lunch modes. The system
operation for call barring can be arranged to prevent unauthorised toll calls for each mode.
Time service can be set automatically or manually by program [006].
Changing the Day/Night/Lunch Modes
The day,night and lunch modes can be changed either automatically at an assigned time in
program [007] or manually by the operator or manager at any desired time.
The lunch mode interrupts the day or night mode. After the lunch mode is finished,the day
or night mode starts again.
If the lunch mode is set using feature number “783#” in the automatic mode,the mode
can only be cancelled by using feature number “780#”. This can be useful during
holidays. The day and night modes are automatically changed at the programmed time in
[007] even if feature number “780#” is not entered. These operations can only be done
by an operator or manager.
The operator and manager can see the status of the mode (day,night or lunch) by the pre-
assigned DSS buttons’LED on the DSS console. Time service can be changed easily by
pressing the pre-assigned DSS buttons.
The following programming items will be affected by the time service.
