- --------S-ZyXEL-----------------------------
-
- The ZyXEL Modems are capable of digitizing speech, the ZFAX software and
- answering machine software like VoiceConnect store the sampled data in
- those files. The Modems are capable of compressing the data down to
- 19.2k CPS (ADPCM) and 9.6k CPS (CELP), the algorithms for the
- compression may be found in the ZyxelVoc package by N. Igl, but as the
- firmware on the modems changes, so might the compression algorithm.
- Playback on the modem is always possible.
