Multistandard pulse/tone repertory
diallers/ringers
PCD3332-2; PCD3332-3;
PCD3332-S
6.1.3.5
Access pause dialling and termination
Access pauses entered during manual dialling or repertory
number storage are not dialled out, but are stored. When
LNR or a repertory number is selected for redial, the
access pauses are dialled out. If at LNR or repertory dial,
an access pause is being dialled out, then depressing the
PAUSE key will terminate the access pause in progress
and dialling will continue at the first non-access pause
digit.
6.1.3.6
Flash/Earth recall
Depending on the option selected (see Table 8),
depressing the Flash key will generate a calibrated
Flash time at output DP/FL, or a calibrated earth time on
the EARTH output. The calibrated earth time is 400 ms,
the flash time is set by diodes as shown in Table 7.
The Flash/Earth will also refer the set to dial mode
selected by the diode option.
6.1.3.7
Data dialling in the pulse dialling mode
If the PCD3332 is initially set to the pulse dial mode
(PTS = ON), depressing the TONE,
or # key will continue
dialling in the DTMF mode. Flash/Earth recall will restore
the pulse dialling mode.
6.1.4
P
ROGRAMMING MODE
The PCD3332 has an on-chip CMOS RAM which can
store up to 10 numbers of 32 digits with a total of 250 digits
(floating memory). If the memory overflows, a warning
beep is generated. If the controller is initially set to the
pulse dial mode, digits can be stored in the pulse dial
and/or in the DTMF mode by depressing key
or # or
using the ‘change mode’ procedure during the store
procedure. This function is best illustrated in Table 22.
6.1.4.1
Memory overflow
A total of 250 digits can be stored. If an attempt is made to
store a number which will bring the total amount of digits
stored to over 250, the TONE output will generate the
memory overflow beeps and the store procedure is
cancelled.
6.1.4.2
Notepad function
In the speech mode, a number can be entered on the
keyboard. This number may be dialled out at the next
off-hook situation by LNR or may be entered in memory.
This function effectively mimics a notepad for a number
passed during a telephone conversation.
6.1.4.3
Repertory and chain dialling
Repertory numbers can be dialled out before or after
manual dialling or LNR, and can be entered one after
another in a chain. However, during transmission of LNR
or a repertory number, a subsequent repertory number is
not accepted. This means that a repertory number can
only be entered if the previous repertory dial or LNR is
ended.
Depending on the MLA diode configuration (see Table 14)
the procedure is as follows:
Direct repertory access: M1 to M10
Two-key repertory access: MRC_0 to MRC_9.
6.1.5
R
INGER MODE
(PCD3332-2/S)
The PCD3332-2/S has a built-in frequency discriminator
circuit, with CE/FDI being used as the discriminator input.
If the ringer frequency supplied is accepted, a ringer
melody is generated. When the ringer melody sounds, the
ringer volume is adjustable in 4 steps using the
/VOL
and #/VOL
+
keys.
Depending on the diode RMS, either a default ringer
melody is selected, or 1 out of 3 ringer melodies may be
selected from the keypad (see Table 12).
6.1.6
R
INGER MODE
(PCD3332-3)
The PCD3332-3 has a built-in frequency discriminator
circuit, with CE/FDI being used as the discriminator input.
If the ringer frequency supplied is accepted, a ringer
melody is generated. When the ringer melody sounds, the
ringer volume is adjustable in 4 steps using the
/VOL
and #/VOL
+
keys.
Depending on the diode RFS, 1 of 2 different input ringer
frequency ranges is selected (see Table 13).
