Abstract: The Teridian 73M2901CE V.22bis single-chip modem has been optimized for short message service (SMS) and V.23 half-duplex operation. Several enhancements have been added to the 73M2901CE to make it more compatible with SMS, including faster turnaround and demodulator settling. This application note describes the use of the 73M2901CE and how it can be used to support SMS and V.23 half-duplex operation.
