SECTION 11 POWER FAILURE TELEPHONES
11.1
Power Failure
The system allows connection for basic telephone service during a power failure.
The power failure operation occurs during a commercial power failure, and is not
affected by blade failure. Power Failure Transfer is provided by connecting to the
CD-4COTA blade.
The CD-4COTA Blade provides 2 Power Failure Transfer circuits.
The CN3 and CN5 connectors each provide connection to four analog trunk ports,
which are not polarity sensitive (tip to tip, ring to ring). The power failure
circuits, however, are not polarity sensitive. A maximum of 15 CD-4COTA blades
per system is allowed.

3. Adjusting the Ring Volume
Use the Volume Control Switch located on the PSA-L adapter to
adjust through the three available volume levels.
Other than receiving calls, no other terminal function is available.
4. When Power is Restored
The IP multiline terminal restarts and reconnects to the network LAN.
However, if you are on a PSTN call when the power is restored, your
conversation continues until the handset is placed in the cradle. Once
this occurs, the IP terminal restarts and reconnects to the LAN.
Other than receiving calls, no other terminal function is available.
