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-4COTB blade.
The CD-4COTB 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 CD-4COTB
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.
