Parameter Description
0 Audio path is in normal speech mode.
1 Audio path is in TTY/CTM mode.
Note
• Requirements for using TTY/CTM features:
- TTY/CTM functionality requires audio mode 5 or 6 with all audio parameters set to their factory default.
To do so, first enter the
AT^SNFS command to select audio mode 5, then use AT^SNFI and AT^SNFO to
restore the default values. Alternatively, factory defaults of all audio parameters in audio modes 2 - 6 can
easily be set with
AT^SNFD.
- Depending on which audio interface the CTM device is connected to, you may need to select the correct
settings with
AT^SAIC.
