Ecology
Description
Environmental issues, such as global warming issue or ecology are most important theme in a world.
In a point of energy saving following ecology functions are implemented in a system.
• Ecology mode
Conditions
Ecology mode (Power Cutting for Terminal)
• System can cut the power for Multiline terminals connected to each interface packages.
Interface packages;
Slot 2 ~ 16 for 408M-A1 (Expansion KSU), 408E-A1, 008E-A1
If user doesn’t want to power cut for the door phone or Analog interface device, such as the Passive Infrared
Sensor which is connected to a hybrid port, these should be connected to slot 1 of Main KSU.
• Power cutting “on” or “off” can be set per individual slot (package) basis, however slot 1 (408M-A1 of
Main KSU) cannot be set, this way remain non power cutting extension in a system for emergency
call, etc.
• Power cutting time will follow with Night mode time schedule. If some terminals are on call at power
cutting start time, the system will wait for the power cutting “off” for the package until all extensions in
the package become idle.
• Power cutting feature can be set “on” or “off” by either combination of following method.
- Night mode time schedule
- Service Code
- Function key
If system reset happened during power cutting “off” state, after the system boots up all extensions will be pow-
ered up normally.
• Combination of time schedule and Manual mode change
If power cutting set “on” manually during scheduled power cutting “off” state, power cutting “on” state
continues until next power cutting “off” time.
The system does not start the cutting telephone power until next schedule.
Vice versa if power cutting is set “off” manually during scheduled power cutting “on” state, power
cutting “off” state continues to next power cutting “on” time.
