Data Sheet
AS2533...6
The centrex keys are not stored in the RAM, and
subsequently entered digits are buffered in FIFO.
Last Number Redial
LNR is a facility that allows resignalling of the last
manually dialled number without keying in all the digits
again. The LNR is repeatable after each off-hook.
The current content of the RAM is overwritten by new
entries.
A manually entered number is automatically stored in
the LNR RAM. The capacity of the RAM is 31 digits. If a
number greater than 31 digits is entered, the LNR facility
will be inhibited (until new entries < 32 digits) and further
entries will be buffered in FIFO.
Pauses can be inserted by pressing the
PS
key (not
AS2535).
Post dialled digits, i.e. digits manually entered after LNR
has been invoked, are not stored in RAM but buffered in
FIFO.
Repeat Dialling (not AS2535)
The last manually dialled number can be repeated
without going on-hook by pressing the
RP
key. If a
called number is engaged, pressing the
RP
key will
break the line for 1.6 second (to get a new dial tone) and
after a pause the number will be repeated.
The repeat function is enabled when prior to pressing
the
RP
key, a number has been dialled, and it can be
invoked an unlimited number of times until next on-hook.
During the 1.6 second break the device is in power down
mode to save current.
Recall Function
A recall (
R1
,
R2
or
R3
key) activation will invoke a flash
(timed loop break), however, the
R1
flash is never
executed in LD mode.
R2
and
R3
will be executed
independent of the mode.
If recall is the first entry in a digit string, it will be stored
in LNR RAM when digit(s) are entered after the recall.
If the recall key is depressed after a digit string has been
entered or dialled out, the recall will not be stored but
buffered in the FIFO together with subsequently entered
digit.
If pressing the recall key is not followed by digit entries,
the LNR RAM remains intact.
After a recall a 270 ms pause will automatically be
executed.
Memory Keys (not AS2534)
The keys
M1
to
M12
are direct memory access keys and
the
MR
key (AS2533/6 only) is used for abbreviated
dialling.

In the on chip RAM, numbers can be stored. Each
number can contain up to 21 digits (including pauses).
During programming multiple pauses can be inserted by
pressing the
PS
(not AS2535) or the
LNR
key. Each
pause inserted within the first 5 entries will automatically
be terminated after 2 seconds whereas pauses inserted
after location 5 in a digit string will halt dialling and can
be terminated manually by pressing the
PS
(not AS2535)
or the
LNR
key. The halt function allows in-dialling to an
extention on a PABX.
Example (45678–123 is stored in M1, where – is a
pause/wait and 123 the extention number):
off-hook, wait for dial tone
press
M1
(45678 is dialled out)
await dial tone from called PABX
press
PS
or
LNR
(123 is dialled out).
Memory dialling is cascadable. However, the content of
one memory must be dialled out before a new can be
invoked.
Sliding Cursor Procedure
To accommodate easy and uncomplicated redialling
(LNR) behind a PABX, a sliding cursor protocol is
implemented. If new entries match the previous RAM
contents, pressing the
LNR
key will dial out the remaining
digits.
If there is an error in matching, the LNR will be inhibited
until next on-hook, and the RAM will contain the new
number.
Example (LNR content 912345, where 9 is access
code):
off-hook, wait for PABX dial tone
press 9 and wait for external dial tone
press
LNR
(12345 will be dialled out).
Tone Generator
The tone generator incorporates the DTMF tones, 3
basic frequencies for the tone ringer and pacifier tones.
