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/CD-4COTC blade.
The CD-4COTA/CD-4COTC Blade provides 2 Power Failure Transfer circuits.
The CN3 and CN5 connectors each provide connection to four analogue 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/CD-4COTC blades per system is allowed.
