Conditions
Power Cut Off Mode
Version 7000 or higher main software is required for this feature.

If the V7000 Enhancement License (0036) expires while in power cut off mode, power does

not automatically recover. If this is expected to occur, disable the Ecology mode before
license expiration, or reboot the system to restore power to the telephones.
The system can cut power to digital (TDM) Multiline Terminals by using power save groups.

A maximum of 16 Power Save groups are supported.
The Power Cut Off mode can be set to On or Off on a per group basis. However, Digital

Station port 1 cannot be set for power cutoff. This keeps the terminal powered on for
emergency calls, etc.
If some terminals are on a call when the Power Cut Off mode is enabled, the system will

wait until all extensions on the blade become idle before cutting power to the slot.
Power Cut Off mode can be set to On or Off using one or a combination of the following

methods:
Night mode time schedule/Manual Night Mode selection

Service Code

Function Key

If the system is reset during the Power Cut Off mode, power to all phones is restored when

the phone system comes back on line.
When a phone has entered Power Cut Off 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 Cut Off mode.
When a terminal is set to Power Cut Off mode, the DSS/BLF status on keys or the console

will not display any status; including Hotel/Motel and Call Forward/DND.
When a terminal is in the Power Cut Off mode, Callback requests or Camp-On cannot be

set until terminal power is restored.
Call Forward Follow Me settings are not followed when the terminal loses power from the

Power Cut Off mode.
If the terminal has Call Forward Both set and then enters the Power Cut Off mode, any calls

directed to the terminal do not follow the Call Forward settings.
Caller ID history is not updated for a terminal in a Power Cut Off mode. Once power to the

terminal is restored, the Caller ID history will start functioning again.
If the system cuts the power via the Power Cut Off mode while a user is on a call, the call is

not lost. If the user places the caller on hold or park, the user's phone then switches to
Power Cut Off mode and the call is lost.
