SECTION 12 POWER FAILURE TELEPHONES
12.1 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 GCD-4COTA blade.
The GCD-4COTA Blade provides 2 Power Failure Transfer circuits.
The CN3 and CN5 connectors each provide connection to four analog trunk
ports, which are polarity sensitive (tip to tip, ring to ring). The power
failure circuits, however, are not polarity sensitive. A maximum of 15
GCD-4COTA blades per system is allowed.
