asterisk users - Feb 2006 - Analyzer for Milliwatt

Hi,

app_milliwatt is a nice tool for a quick check of the
line quality.

Anyway, hearing to that tone for more than a minute is
painful.

Does anyone know the "opposite" application, i.e. an
application, that "hears" and listens for a 1000 Hz
tone and displays the quality in any unit?

If not, I'll think about developing one.


Regards,
Roger.

No, but it sure would be nice to have some tools to diagnose
quality issues.

Hi,

since I need rather a tool not that versatile but within some
days than a very nice tool available in some weeks, I've started
to code a little tool, which is just doing some analysis for one
given (but variable) frequency.

Thus it can be used as opposite for the Milliwatt application.
For some convenience it also produces a tone, of that frequency,
it is analyzing.

I've called the new application Mwanalyze.

E.g.
Mwanalyze(16,8000,60,328) is producing a 500 Hz tone.


For a first look, fetch:

Docu inline.

It does not yet perform any analysis, but already generates
the tone.


I will tell here, when finished.


Roger.
