Threshold Current is based on the two line intersection method specified in Telcordia GR-468-Core. Line 1 from 6 mA to 8 mA. Line 2 from 0
mA to 2 mA.
Series Resistance is the slope of the Voltage-Current line from 8 to 12 mA.
Slope efficiency, is the slope of the best fit LI line from 8 mA above threshold to 12 mA.
