CODEC Function (IC201, 202, 250, 251)
Infineon PEB2466 CODEC is installed. The analogue features such as BN, frequency characteristic, volume level, sidetone are
configured by ASIC CODEC interface DCLK, CS, DOUT, DIN. In addition, the CODEC has an internal I/O port that supports Hook
detection, DTMF detection, BELL relay control and DIAG relay control. Also, it converts A/D to D/A, and 4-line-analogue signal to
PCM code in G.711 format.
