Hello Dave, I hope the following will help you REN calculation for DC resistance
For 0-100VDC REN=25 megohms/minimum DC resistance For 100-200VDC 150 kilohms/minimum DC resistance For Ringer type B AC REN=8000/mim. on-hook AC imped for lowest frequency AC REN=8000/Min. on-hook AC imped. for highest frequency Ringer type allows a ringer impedance of 1600 ohms minimum on a single line DC current during ringing DC REN=DC current Max(mA)/0.6mA The largest values for AC and DC REN are the values used.
