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.
