3.2 Operation During Power Failure
If the telephone becomes disconnected from the power supply (e.g., power loss)
the telephone display is blank.
To make a call, lift the handset to receive dial tone from the analog line. Dial as
normal.
If a call is received on the analog line, the Power Fail Adapter rings. Lift the
handset to answer.
If the telephone is connected to the power supply, but disconnected from the
UNIVERGE SV9100 system (e.g., data network failure), the IP telephone
attempts to reconnect. If this fails, press the button on the top of the adapter.
Refer to Figure 8-2 Power Fail Adapter Connection on page 8-4. This puts the IP
telephone in analog mode. The telephone display shows LINE -> PSTN.
To make a call, lift the handset to receive dial tone from the analog line. Dial as
normal.
