Default Transmit Call Progress Tone Patterns

To form call progress tone patterns, the call progress tones are combined and separated by intervals of silence. Table 7-11 shows the default transmit call progress tone patterns and their parameters.

Each pattern is composed of one to three cycle blocks, which include the following components:

Tone ID

ON duration

OFF duration

Number of times to repeat the cycle block

0xFFFF = continuous
