POTS Port 1 Ringing Generator (low when not ringing)
POTS Port 1 Ringing Generator (high when not ringing)
POTS Port 1 Line Voltage Adjustment (low if sending
FSK to a Caller Display unit, as it is intended to make
the SLIC present a high impedance to the POTS line)
POTS Port 1 Hook Switch Status Detector
(on-hook = low)
POTS Port 2 Hook Switch Status Detector
(on-hook = low)
