[Asterisk-Users] [OT] Old Building Needs a New Telephone System

[Paul Rodan]

It actually uses 2 wires for positive and 2 wires for ground/negative? So
it's combing 2 wires (instead of 1) to deliver more power? 

Which 2 are positive and which 2 are negative/ground?

A PoE-enabled connection needs all four pairs. Two pairs for Tx/Rx, one 
pair for power, one pair for ground.
