<Huawei> system-view
[Huawei] voice
[Huawei-voice] tone 3
[Huawei-voice-tone-3] tone-cadence continus 1

Scenario 2:

[Huawei-voice-tone-3] tone-cadence sequence 400 200 1 500 200 2

Set up to 2 cadences. The first one plays 400ms, then begins a silence period that lasts 200ms; the second plays for 500ms, and then begins a 200ms' silence. The values '1' and '2' are base-frequency-flags, which should to be converted to binary numbers as follows:

1 == 0001 frequency 1

2 == 0010 frequency 2

3 == 0011 frequency 1 and frequence 2

4 == 0100 frequency 3

5 == 0101 frequency 1 and frequency 3

......

After the above configuration, the tone that comes out when one picks up the phone sounds almost the same as before, except that the cadence differs.
