Talk:High-voltage differential signalling

I understand a need for a term to distinguish "traditional" differential signalling (0 to +5V RS-485, SCSI, Ethernet, etc. ) from the newly popular low voltage differential signaling.

Is there a better term we could use instead of High voltage ?

According to High voltage, "The exact definition of "high" varies but the IEE defines it to be over 1000V." According to Electricity distribution, "low-voltage (less than 1000V)".

I have not yet seen a differential signaling system that used more than the 48 V used by telephone systems.

Is it one "L" or two "LL" ?
