Description
Dial Tone
Dial tone is a continuous sound. The range 400~450hz is composed of single frequency or
multiple frequencies (up to three, the interval between different frequencies is at least 25Hz).
The level of the dial tone should be -10dBm + 5dB. The Chinese standard dial-up sounds are
composed of a single frequency of 450hz, and the duration is generally 10 seconds.
Default value: voice low frequency "450" HZ, voice high frequency "0" HZ, mute time "0"
Ms, the pronunciation time "0" ms.
Busy Tone
The busy tone is periodic sounds fast-paced, produced by tone and mute alternately, and the
signal is equal to the basic tone cycle of the silent period. The duration of signal tone and
mute is relatively short, and the complete cycle time composed of a single tone and mute is
300~1100 milliseconds, and the ratio between signal duration and silent time should be
between 0.67~1.5. Generally use the single tone frequency range is 400~500hz, Chinese
using single frequency 450hz signal China standard; busy for 350 milliseconds, mute for 350
milliseconds complete busy period of 700 Ms.
Default value: voice low frequency "450" HZ, voice high frequency "0" HZ, mute time
"350" Ms, the pronunciation time "350" ms.
Ring Tone
Ring back tone is a slow rhythmic periodic voice, which is generated alternately by tone and
mute, and the period of signal tone is shorter than that of mute. The period of signal tone is
in 0.67~1.5 sec, and the period of silence is 3~6 seconds, and a complete ringing period is
between 3.67~7.5 second. The user first heard the signal cycle, followed by the mute cycle.
Back tone usually uses a single frequency, and the frequency range is between 400~500hz.
Chinese standard ring back tone and bell sound is 1 second stop 4 seconds, ringback tone
using a single frequency 450hz.
Default value: voice low frequency "450" HZ, voice high frequency "0" HZ, mute time
"4000" ms, the pronunciation time "1000" ms.
Congestion Tone
Busy rhythm can also slower than congestion tone rhythm.
Default value: voice low frequency "450" HZ, voice high frequency "0" HZ, mute time
"350" ms, the pronunciation time "350" ms.
Call Waiting Tone
Call waiting tone is a slow rhythm. There are two kinds of voice: one is the duration of
signal tone in 300~500 milliseconds, the second is 8~10 100~200, the other is the signal tone
lasts for 100~200 milliseconds, and then the mute 8~10 seconds after mute 100~200
milliseconds. The Chinese standard waits, in which the sound of the signal lasts for 0.4
seconds, and the mute is 4 seconds. The signal sounds usually use a single frequency 450hz.
The call waiting tone is played in the two directions of the call and the call, and the
characteristics of the play are slightly different in different directions.
Default value: voice low frequency "450" HZ, voice high frequency "0" HZ, mute time
"4000" ms, the pronunciation time "400" ms.
Second Dial Tone
Default value: voice low frequency "410" HZ, voice high frequency "0" HZ, mute time "0"
ms, the pronunciation time "0" ms.
Recordtone
Default value: voice low frequency "950" HZ, voice high frequency "0" HZ, mute time
"1000" ms, the pronunciation time "400" ms.
Info
Default value: voice low frequency "450" HZ, voice high frequency "0" HZ, mute time
"400" ms, the pronunciation time "400" ms.
