RD
Loop Current Threshold Programming Pin - A resistor between this pin and ground will determine the
trigger level for the loop current detect circuit. See Equation 7.

ROH
Off Hook Overload Setting Resistor - Used to set combined overhead for voice and pulse metering
signals. See Equation 10.

ILIM
Current Limit Programming Pin - A resistor between this pin and ground will determine the constant
current limit of the feed curve. See Equation 11.

RSYNC_REV
Ring Synchronization Input and Reversal Time Setting. A resistor between this pin and GND
determines the polarity reversal time. Synchronization of the closing of the relay at zero voltage is
achieved via a ring sync pulse (5V to 0V) synchronized to the ring signal zero voltage crossing
(Reference Figure 18).
