a) addresses the support of safety extra low voltage (SELV) and limited power source (LPS) applications that provide remote power over:
• 4-pair balanced cabling in accordance with the reference implementations of ISO/IEC 11801 series standards using currents per conductor of up to 500 mA;• 1-pair balanced cabling using currents per conductor of up to 1 000 mA;
and targets the support of applications that provide remote power over balanced cabling to terminal equipment
