SPEECH NETWORK WITH DIALER INTERFACE
INTRODUCTION
The S1T8501 is a speech network integrated circuit which includes
the following components: transmit amp, receive amp, DTMF amp,
voltage regulator, line equalizer, and voltage comparator. It handles
the voice signal, performing the 2/4 wires interface and changing the
gain on both sending and receiving amplifiers to compensate the line
current. The S1T8501 can work in fixed gain mode.
