2.3.3 Make-Before-Break Operation - All Versions
To use make-before-break operation, change the logic
inputs from the ringing state directly to the talk state.
Application of the talk state opens the ringing return
switch, SW3, as the break switches SW1 and SW2
close. The ringing switch, SW4, remains closed until
the next zero-crossing of the ringing current. While in
the make-before-break state, ringing potentials in
excess of the CPC7592 protection circuitry thresholds
will be diverted away from the SLIC.

2.3.4 Break-Before-Make Operation - CPC7592xA/B
Break-before-make operation of the CPC7592xA/B
can be achieved using two different techniques.
The first method uses manipulation of the INRINGING
and INTEST logic inputs as shown in
1.
At the end of the ringing state apply the all off
state (1,1). This releases the ringing return
switch (SW3) while the ringing switch (SW4)
remains on, waiting for the next zero current
event.
2.
Hold the all off state for at least one-half of a
ringing cycle to assure that a zero crossing event
occurs and that SW4, the ringing switch, has
opened.
3.
Apply inputs for the next desired state. For the
talk state, the inputs would be (0,0).
Break-before-make operation occurs when the ringing
switches open before the break switches SW1 and
SW2 close.
