PLD1 controls and monitors SLIC/CODEC LSI of each analog line port.
PLD2 controls the trunk controller DSP which is used in each analog trunk port.
SLIC/CODEC is exclusive LSI which is used for analog line interface.
1) Line interface power supply
2) Dial pulse detection
3) DTMF receiver / Caller ID generation
4) Bell signal generation
5) Hooking detection / Ringtrip detection
6) 2W/4W conversion
7) CODEC function
DSP(CO) is exclusive LSI which is used analog trunk port.
1) Dial pulse generation
