Circuit Operation (Base Unit)

General Description:

(BBIC, Flash Memory, EERROM) is a digital speech/signal processing system that implements all the functions of speech
compression, record and playback, and memory management required in a digital telephone answering machine.
The BBIC system is fully controlled by a host processor. The host processor provides activation and control of all that functions
as follows.

4.5.1.

BBIC (Base Band IC: IC501)

•

Voice Message Recording/Play back

The BBIC system uses a proprietary speech compression technique to record and store voice message in Flash Memory.
An error correction algorithm is used to enable playback of these messages from the Flash Memory.

•

DTMF Generator

When the DTMF data from the handset is received, the DTMF signal is output.

•

Synthesized Voice (Pre-recorded message)

The BBIC implements synthesized Voice, utilizing the built in speech detector and a Flash Memory, which stored the vocabulary.

•

Caller ID demodulation

The BBIC implements monitor and demodulate the FSK/DTMF signals that provide CID information from the Central Office.

•

Digital Switching

The voice signal from telephone line is transmitted to the handset or the voice signal from the handset is transmitted to the
Telephone line, etc. They are determined by the signal path route operation of voice signal.

•

Block Interface Circuit

RF part, LED, Key scan, Speaker, Telephone line.

4.5.2.

Flash Memory (IC502)

Main program data is stored.

4.5.3.

Flash Memory (IC601)

Following information data is stored.

•

Voice signal

ex: Pre-recorded Greeting message, Incoming message

4.5.4.

EEPROM (IC611)

Following information data is stored.

•

Settings

ex: message numbers, ID code, Flash Time, Tone/Pulse
