Call-Progress Tone Parameters
This section covers all the call-progress tones that the Cisco ATA supports, and contains the following
topics:
• List of Call-Progress Tone Parameters, page 5-21
• Tone Parameter Syntax, page 5-21
• How to Calculate Scaling Factors, page 5-22
• Recommended Values, page 5-22
• Specific Call-Progress Tone Parameter Information, page 5-23
List of Call-Progress Tone Parameters
The following list contains the names of the call-progress tone parameters:
• DialTone
• BusyTone
• ReorderTone
• RingBackTone
• CallWaitTone
• ConfirmTone
Tone Parameter Syntax
Each tone is specified by nine integers, as follows:
ntone, freq0, freq1, level0, level1, steady, on-time, off-time, total-tone- time
• ntone is the number of frequency components (0, 1 or 2).
• freq[0] (Hz) is the transformed frequency of the first frequency component (-32768 to 32767).
Note Only positive values can be configured to the Cisco ATA 186. For negative values, use the 16-bit
2’s-complement value. For example, enter -1 as 65535 or 0xffff.
• freq[1] is the transformed frequency of the second frequency component (-32768 to 32767).
• level[0] is the transformed amplitude of the first frequency component (-32768 to 32767).
• level[1] is the transformed amplitude of the second frequency component (-32768 to 32767).
• steady controls whether the tone is constant or intermittent. A value of 1 indicates a steady tone and
causes the Cisco ATA to ignore the on-time and off-time parameters. A value of 0 indicates an on/off
tone pattern and causes the Cisco ATA to use the on-time and off-time parameters.
• on-time controls the length of time the tone is heard in milliseconds (ms) expressed as an integer
from 0 to 0xffff sample at 8000 samples/second.
• off-time controls the length of time between audible tones in milliseconds (ms) expressed as an
integer from 0 to 0xffff sample at 8000 samples/second.
