Chapter 8 Profile and Web Page Parameters and Defaults

Parameter Details

BusyTone, CallWaitTone, DialTone, DialTone2, and RingBackTone Parameter Details

The following parameters specify tones that can consist of a single frequency or of two frequencies that play simultaneously, and of a cadence with up to two on-off pairs:

•BusyTone—Tone that plays when the called party’s line is busy

•CallWaitTone—Tone that plays to indicate that you have a call waiting

•DialTone—Tone that plays when the phone is ready to accept the first digit of a telephone number or an IP address

•DialTone2—Secondary dial tone (for example, the dial tone that plays when you dial a number to obtain an outside line)

•RingBackTone—Tone that plays to indicate that the called party’s line is ringing

For the default values of these parameters, which are suitable for the United Sates, see Table 8-4.

The syntax of these parameters is:

parameter:NumOfFreqs,TFreq_1,TAmplitude_1,TFreq_2,TAmplitude_2, NumOfOnOffPairs,OnTime_1,OffTime_1,OnTime_2,OffTime_2,TotalToneTime

where:

•parameter is BusyTone, CallWaitTone, DialTone, DialTone2, or RingBackTone.

•NumOfFreqs is the number of frequencies in the tone (1 or 2).

•TFreq_1 and TFreq_2 are the transformed frequencies of the first and second frequencies, respectively. Calculate each value as follows, where Frequency is the desired frequency in Hz:

32767 * cos(2 * pi * Frequency/8000)

The range of each value is –32768 to 32767. Set a value to 0 if the frequency does not exist.

For negative values, use the 16-bit 2’s complement value. For example, enter –1 as 65535 or as 0xffff.
