18.19 AT^SRTC Ring tone configuration
The AT^SRTC read command returns the current <type> and current <volume>. The read command can be
used while test playback is off or on. In the latter case, see execute command for details.
The AT^SRTC execute command is intended for testing. It starts to play a melody from the audio output currently
selected with AT^SNFS. To deactivate test playback use AT^SRTC again.
During test playback, you can enter the write command to select another melody and adjust the volume. Also,
you can enter the read command to check the type and volume of the current ring tone, and to view the status
of playback (on / off). The test ringing signal cannot be activated when an MTC is ringing (ERROR).
Selecting <volume>=0 during the test, immediately stops playback. After this, ring tones will be muted until you
change <volume> using the write command.
The AT^SRTC write command chooses the type and volume of ring tones. The settings can be changed no matter
whether or not the ME is ringing. The selected type and volume are saved in the non-volatile Flash memory and,
thus, are retained after Power Down. However, bear in mind that the selected melody does not take effect imme-
diately if entered during an MTC call (see note below).
Unlike all other ring tones, <type>=0 is not stored. This is because it is intended only to quickly mute the tone
or melody currently played. So <type>=0 only stops immediately the audible ring tone, but does not terminate
the RING URC.
