Circuit Operation (Base Unit)

General Description:

(DSP, Flash Memory) is a digital speech/signal processing system that implements all the functions of speech compression,
and memory management.
The DSP system is fully controlled by a host processor DSP. The host processor provides activation and control of all that
functions as follows.

4.6.1.

DSP (Digital Speech/Signal Processing: IC504)

•

Caller ID demodulation

The DSP implements monitor that provide CID information from the Central Office.

•

Digital Switching

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

•

Block Interface Circuit

RF part, LED, Key scan, Ethernet interface.

•

VOIP (Voice over Internet Protocol)

The voice data encoding/decoding and RTP (Real-time Transport Protocol) packet conversion are performed at the VoIP part.
