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-4COT( ) blade.
The GCD-4COT( ) 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-4COT( ) blades per
system is allowed.
