POTS Port 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 Hook Switch Status Detector
(on-hook = low)
For manufacturers’ use only. Connect to DVSS directly
CMX605 C-BUS Interface - Reply Data
CMX605 C-BUS Interface - Command Data
CMX605 C-BUS Interface - Serial Clock
The positive analogue supply rail. Levels and voltages
are dependent upon this supply. This pin should be
decoupled to AVSS by a capacitor
