Control Interface: input bit 0.
Control Interface: input bit 1.
Control interface: input bit 2.
Power down input. Normally connected to CVCC (or to logic level high).
Control gain interface:
Not connected.
Logic interface output of the supervision detector (active low).
Metering pulse clock input (12 KHz or 16KHz square wave).
Metering burst shaping external capacitor.
Metering burst shaping external capacitor.
Metering pulse cancellation buffer output. TTX filter network should be connected to
this point. If not used should be left open.
Metering pulse buffer input this signal is sent to the line and used to perform TTX
filtering.
4 wire input port (RX input). A 100 kΩ external resistor must be connected to AGND to
bias the input stage. This signal is referred to AGND. If connected to single supply
CODEC output it must be DC decoupled with proper capacitor.
RX buffer output, (the AC impedance is connected from this node to ZAC).
AC impedance synthesis.
