Precise Frequency Detector Modification and Special Tone Generation

筆者: Jeff Sorensen

要約: Although the Teridian 73M2901CE single-chip V.22bis modem is preprogrammed for most low-speed dial-up applications, it can detect or generate tones that are not part of its default set. This application note describes the procedure for modifying detect frequencies of the 73M2901CE’s precise call progress filters.
