IC300, IC101
IC101 is a digital speech/signal processing system that implements all the functions of speech compression.
The DSP system is fully controlled by a host processor DSP. The host processor provides activation and control of all these func-
tions. IC300 is a BMC controll and signal processing system to transmitte signal to Handsets
