The power fail adapter is an add-on module for the IP (DT800/DT700) multiline
telephones and digital (DT400/DT300) multiline telephones. It allows connection to
an analog trunk if the power or system connection fails, or the IP telephone loses
connection to the UNIVERGE SV9100 system.
No programming is required on the UNIVERGE SV9100 to support this adapter.

Connecting to an IP Telephone
The Power Fail Adapter connects to an analog PSTN (Public Switched Telephone
Network) line. At a small branch office, for example, this may be the same line that
is used for faxes/modems/etc. The handset is also connected to the Power Fail
Adapter. It is necessary to unplug it from the IP telephone and reconnect to the
adapter. This allows the speech path to be redirected to the handset during a
power/network failure.
