Product specification
Multistandard pulse/tone repertory
diallers/ringers
PCD3332-2; PCD3332-3;
PCD3332-S
5.2.2.11
Flash Time Select
These two diodes set the calibrated flash pulse duration:
100, 115, 270 or 600 ms for the DP/FL output, when this
output is selected. When the EARTH output is selected the
earth pulse is 400 ms.
5.2.2.12
Low Frequency amplifier Enable (LFE:
PCD3332-3)
Output LFE can be used to enable the TEA108x or
TEA109x listening-in or hands-free IC. The HOOK key
functions as a toggle to control the hands-free mode
(LFE = LOW) or listening-in mode (LFE = HIGH). while in
the off-hook condition the key can be pressed and kept
down to replace the handset while saving the LFE and
DP/FL selection.

OOK MODES
Figure 9 illustrates the different HOOK modes and how
those modes are entered (PCD3332-3). For the
PCD3332-2/S only the ‘handset’ mode and ‘on-hook’
mode are valid.
