Auxiliary Power Supplies
Nonessential features of the attendant console, such as the optional 27B1
selector console, and DCP terminals derive their power from an auxiliary power
source. One console can connect to R8csi, and 3 consoles can connect to each
cabinet stack or R8r. Each cabinet can derive auxiliary power from the system
and through the auxiliary cable located in the trunk/auxiliary field. Auxiliary power
for a primary attendant console should be provided through this cable so the
console remains fully operational during short power outages.
Local, auxiliary power supply
Consoles can use either local or phantom power, depending on the distance
between the console and the DEFINITY ECS cabinet. Over short distances,
phantom power is attractive, because no additional hardware is necessary—
power is supplied via the telephone circuit itself. For longer distances, you need
a local power supply.
