Disconnect Tone Detection

[jlumague]

Hi,

newbie in detecting frequency needs some help here guys, I've read some entries here that you can manually get the frequency of the disconnect tone using cooledit. I downloaded the program but I'm having a hard getting the correct value using that utilities. Any help on how to get the frequency would be a great help to me. I attached my disconnect tone here if you want to detet it.

 

Thanks in advance.

This disconnect tone is quite unusual.

 

The tones are a single frequency of 564Hz.

 

The cadence is:

 

ON for 165ms

OFF for 395ms

ON for 300ms

OFF for 270ms

 

I'd recommend the Dialogic TSP settings to be:

 

Freq 1 : 564

Freq 1 deviation : 50

Freq 2 : 0

Freq 2 deviation : 0

On time : 23

On time deviation : 10

Off time : 33

Off time deviation : 10

Repetition : 3

Hi,

Thanks for the reply, I tried using that TSP already but still no luck in detecting the disconnect tone. I did try using perfect call analysis also in defining the tones using dx_blddtcad() function still the same result.

 

Thanks in advance,

Try changing the repetitions count down, and increasing the deviation settings until it detects the disconnect - and please let us know at what settings the disconnect tone became detected.

hi,

I can detect the disconnect tone already. this is the paremeter that works.

 

Freq 1 : 500

Freq 1 deviation : 100

Freq 2 : 0

Freq 2 deviation : 0

On time : 23

On time deviation : 10

Off time : 0

Off time deviation : 0

Repetition : 2

Is there any problem eventhough I have no value for off time and a deviation of 100?

 

Thanks.

By disabling the 'off' cadence while having the 'repetition set to 2 you are probably setting the card to detect on ON tone of between 260ms and 660ms - and one of the ON tones falls in this range.

 

If that works for you OK then you can stick with it - I'd try to experiment with using the OFF setting as well to create a ON/OFF cadence based detection - this reduces the chance of false detections.
