73M2901CE Quasi-Synchronous Operation


The Teridian 73M2901CE, a V.22bis single-chip modem, supports a host-based software module for V.42/MNP 2-4 error-correction protocol and SDLC operation. These protocol operations require a special quasi-synchronous mode, which performs an asynchronous-to-synchronous conversion (and vice versa) to the data going over the data-terminal-equipment (DTE) interface. This application note details the operation of the quasi-synchronous mode. Read full article.
