4.2.5.
Analog Circuit
1. Speaker phone call
Transmitting signal is input from microphone MIC1 (differential amplifier circuit) 
 input to IC101-pin L19, M19  A/D conver-
sion, Gain adjustment and echo cancel by built-in DSP of IC101.
Receiving signal input from IP Line 
 Gain adjustment and D/A conversion by DSP of IC101  output from IC101-pin V18,
V19 
 output to Speaker.
2. Handset call
Transmitting signal is input from handset microphone 
 input to IC101-pin M17,M18  A/D conversion, Gain adjustment and
echo cancel by built-in DSP of IC101.
Receiving signal input from IP Line 
 Gain adjustment and D/A conversion by DSP of IC101  IC101-pinK18,K19  output
to handset speaker.

3. Headset call
Transmitting signal is input from headset microphone 
 input to IC101-pin N15  A/D conversion, Gain adjustment and echo
cancel by built-in DSP of IC101.
Receiving signal input from IP Line 
 Gain adjustment and D/A conversion by DSP of IC101  IC101-pinL17  output to
headset speaker.
4.2.6.
Key Circuit
The key data is under the matrix control by IC101.
The key information output from KEY_OUT is input into KEY_IN, when the key is pressed.
The HOOK key is independent from Key Scan Matrix and taken into the port singularly.

4.2.7.
LED Circuit
The lighting of the LEDs is controlled(static lighting) by IC101.
4.2.8.
ASIC
IC101 and IC503(ASIC) are connected by an I2C communication.
EHS terminals are controlled by IC503 (ASIC).
*This ASIC supports Plantronics  and Jabra  EHS.
Plantronics control signals : PSB IN/OUT
Jabra control signals          : JABRA_UTX/URX
The audio signals are exchanged with IC101 through HEADSET JACK.
4.2.9.
BT(Bluetooth) Module
 The BT Module (IC105) is controlled by IC101 using serial communication command (IC105 pin6,9).
This BT Module supports Plantronics and Jabra BT headset (narrow&wide band), voice  signals can be transmitted/received
through PCM (IC105 pin2,3,31,32)
