When privacy mute is activated a reminder tone is
applied to the ear piece every 274ms.
Moving 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.
DTMF Tones
The DTMF generator provides 7 frequencies,
namely:
Low group
Digit 1-2-3
Digit 4-5-6
Digit 7-8-9
Digit *-0-#
697Hz
770Hz
852Hz
941Hz
High group
Digit 1-4-7-*
Digit 2-5-8-0
Digit 3-6-9-#
1209Hz
1336 Hz
1477Hz
The MF output levels are -6/-8 dBm and the
preemphasis is 2.6dB.
Tone Ringer
The Tone Ringer of the SA2532P incorporates a
Discriminator Circuit and a three tone Melody
Generator.
When a Valid Ring Signal is detected the Melody
generator is activated and creates a ringing signal
comprising 3 frequencies F1 (1065Hz), F2
(1420Hz) and F3 (1734Hz).
These frequencies are repeated in a sequence of 6
time slots constructed by the frequencies
F1
F2
F3
F1
F2
F3
The repetition rate allows these six frequencies to
be repeated 1,4,7 or 10 times per second and can
be set by pin option as follows:
Pin RR
R1
R2
R3
R4
OPEN
Repetition Rate
1 time
4 times
7 times
10 times
disabled
.
Ring Frequency Discrimination
The Ring Frequency Discriminator assures that
signals with a frequency between 13 Hz to 70 Hz
are regarded as valid ring signals. When a valid ring
signal is detected, the melody generator is activated
and remains active as long as the ring signal is
present. Once the melody generator has been
started, the ring signal is continuously monitored
and the melody generator is instantly turned on or
off according to the momentary presence of a valid
or invalid ring signal respectively (until next POR of
off-hook).
