Auxiliary power supplies

Local auxiliary power supply
Consoles can use either local or phantom power, depending on the distance
between the console and the cabinet. Over short distances, phantom power is
attractive because no additional hardware is necessary—power is supplied using
the telephone circuit itself. For longer distances, you need a local power supply.
Table 5 shows cabling distances for the 302 attendant console.
