Title: PC server telecommunications power system

Abstract: A system within a PC server cabinet for receiving an externally suppliedloop feed voltage (-48 VDC) and generating a ringing voltage (75 VAC) fromthe loop feed voltage. For universal applicability, the ringing voltagegenerator is preferably located in a 5.25 inch standard disk-drive housingof the cabinet, allowing it to fit into any PC. All requiredtelecommunications signaling and power is thereby provided in the PC whilelimiting accidental user exposure to hazardous ringing signal voltagelevels.
