Ecology
Description
Environmental issues, such as global warming or ecology are one of the most important themes in
today's world. The following energy saving features are implemented in this system:
• Ecology mode
• Power Saving Mode
Conditions
Ecology mode (Power Cutting for Terminal)
• System can cut the power for Multiline Terminals connected to each interface boards. An SL2100
has a Hybrid port, therefore the Single Line Terminal or Doorphone will be controlled as power
cutting terminal.
Interface boards;
Slot 1 ~ 4 for 082U, 008U
• Power cutting “on” or “off” can be set per individual slot (board) basis, however slot 1 (082U-B1) of
Main Chassis cannot be set, this keeps the extension powered on 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 board until all extensions in
the board 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, all extensions will be powered up normally
after the system boots up.
Power cut mode will not be enabled, for the slot, until all phones on the package are idle.
When the system is in power cut mode, a user cannot dial an emergency number (911) from the station.
The station is unusable until it comes out of power cut mode.
• Combination of time schedule and Manual mode change
• When using department group step calling and ecology mode, there must be at least two terminals
functioning for the step call feature to work.
• When a phone has entered power cutting mode, any direct calls to the terminal will follow the
stations call forwarding. If the phone is part of a chain call forwarding scenario, the chain call
forwarding will not process while the phone is in power cutting mode.
• When a terminal is set to power cutting mode, the DSS/BLF status on keys or the console will not
display any status including Hotel/Motel and Call Forward/DND.
• When a phone is in power cutting mode, you cannot set call back requests or camp on to the
terminal until power is restored.
• Call Forward follow me settings will not be followed when the terminal loses power from the power
cutting feature.
• If the terminal has Call Forward Both set and then enters power cutting mode, any calls directed to
the terminal will not follow the call forward settings.
• Caller ID history is not updated for a phone which is in power cutting mode from the ecology feature.
Once power is restored to the phone the caller ID history will start functioning again.
