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.
When connecting the RJ-61 cables to the COIU Blade, note the
position of the Power Failure connector.
Do not confuse connector CN3 as the CN2 trunk connector.
