V.23 Operation Including PAVI

筆者: Jeff Sorensen

要約: The Teridian 73M2901CE, a V.22bis single-chip modem, has a special V.23 PAVI operation feature that allows switching of the two transmission channels during communication. Transmission speed may then be changed dynamically during a connection: the transmitter at 75bps may become the transmitter at 1200bps and vice versa. This application note discusses the PAVI feature, including Back-to-Main Channel and Main-to-Back Channel turnarounds.
