Call Waiting Tone Question

Unanswered Question
Apr 16th, 2010

Can you please assist in following up with this question for me?  Our current ATA is configured for Call Waiting tone with these parameters (config template can be attached if needed):

<Default_CWT_1_ ua="na">1</Default_CWT_1_>

<CWT1_Cadence ua="na"> 31.2(.3/10.1)</CWT1_Cadence>

<CWT_Frequency ua="na">440@-22</CWT_Frequency>

Per the bellcore spec, is this the same as? 440@-22;31.2(.3/10.1/1)

My main confusion is around the CWT1_Cadence value since it is missing the tone index parameter; ie: requency@db;repeated times(on time/off time/tone index).  Is there a shorthand value since there is only 1 tone listed in the CWT_Frequency parameter?

Thanks,

Adam

I have this problem too.

Dev's response to your question is below.

·         ToneScript – A mini-script that specifies the frequency, level and cadence parameters of a call progress tone. May contain up to 127 characters. Syntax: FreqScript;Z1[;Z2]. The section Zi is similar to the Si section in a CadScript except that each on/off segment is followed by a frequency components parameter: Zi = Di(oni,1/offi,1/fi,1[,oni,2/offi,2/fi,2 [,oni,3/offi,3/fi,3 [,oni,4/offi,4/fi,4 [,oni,5/offi,5/fi,5 [,oni,6/offi,6/fi,6]]]]]), where fi,j = n1[+n2]+n3[+n4[+n5[+n6]]]]] and 1 < nk < 6 indicates which of the frequency components given in the FreqScript shall be used in that segment; if more than one frequency component is used in a segment, the components are summed together.

Example   1: Dial   Tone

350@-19,440@-19;10(*/0/1+2)

Number of Frequencies = 2

Frequency 1 = 350 Hz at –19 dBm

Frequency 2 = 440 Hz at –19 dBm

Number of Cadence Sections = 1

Cadence Section 1: Section Length = 10 s

Number of Segments = 1

Segment 1: On=forever, with Frequencies 1 and 2

Total Tone Length = 10s

Example   2: Stutter   Tone

350@-19,440@-19;2(.1/.1/1+2);10(*/0/1+2)

Number of Frequencies = 2

Frequency 1 = 350 Hz at –19 dBm

Frequency 2 = 440 Hz at –19 dBm

Number of Cadence Sections = 2

Cadence Section 1: Section Length = 2s

Number of Segments = 1

Segment 1: On=0.1s, Off=0.1s with Frequencies 1   and 2

Cadence Section 2: Section Length = 10s

Number of Segments = 1

Segment 1: On=forever, with Frequencies 1 and 2

Total Tone Length = 12s

Example   3: SIT   Tone

985@-16,1428@-16,1777@-16;20(.380/0/1,.380/0/2,.380/0/3,0/4/0)

Number of Frequencies = 3

Frequency 1 = 985 Hz at –16 dBm

Frequency 2 = 1428 Hz at –16 dBm

Frequency 3 = 1777 Hz at –16 dBm

Number of Cadence Sections = 1

Cadence Section 1: Section Length = 20s

Number of Segments = 4

Segment 1: On=0.38s, Off=0s, with Frequency 1

Segment 2: On=0.38s, Off=0s, with Frequency 2

Segment 3: On=0.38s, Off=0s, with Frequency 3

Segment 4: On=0s, Off=4s, with no frequency   components

Total Tone Length = 20s

Thanks Nelson.  Although this is very helpful, this doesn't answer my original questions below:

Per the bellcore spec, is this the same as? 440@-22;31.2(.3/10.1/1)

My main confusion is around the CWT1_Cadence value since it is missing the tone index parameter; ie: requency@db;repeated times(on time/off time/tone index).  Is there a shorthand value since there is only 1 tone listed in the CWT_Frequency parameter?

The Default CWT parameter is referencing which CWTnumber Cadence to use.  Since 1 is in Default CWT, it would use the freq setup in CWT1 Cadence. So from what you've written, it looks like match.
