The digital negative supply rail (ground)
For manufacturer's use only. Connect to DV
HDLC Chip Reset
POTS Port 2 Ringing Generator (low when not ringing)
POTS Port 2 Ringing Generator (high when not ringing)
API/RS232 Port Rx Data (inactive = high)
API/RS232 Port Tx Data (high when inactive)
POTS Port 2 Line Voltage Adjustment (low when sending FSK
to a Caller Display unit. If low, it makes the SLIC present a
high impedance to the POTS line)
B-channel Select (high selects channel B1).
ISDN Line Failure Indicator
The digital positive supply rail. Levels and voltages are
dependent upon this supply. This pin should be decoupled to
