NAME
tonedebug - Test parameters for the libvpb programmable tone detector
SYNOPSIS
tonedebug [options]
DESCRIPTION
The tonedebug utility assists with quickly testing tone detector parameters against the
signals they are intended to detect. It has three main modes of operation for testing
single continuous or pulsed tones, or for testing a set of tones specified in the
environment.
OPTIONS
The following common options apply for all modes:
--card number
Explicitly select the card to test. Default is card 0.
--port number
Explicitly select the port to test. Default is port 0 of the card being tested.
-w wavfile
Specify a wav file to play the tones from. For OpenLine and OpenSwitch cards it
should be played to an FXO port with no phone line connected, and the tone detector
will process the reflected signal from the hybrid circuit. The OpenPCI cards have
almost no echo from this circuit, but an on hook phone connected to an FXS port
should produce a detectable echo signal.
-s filename.c
Writes out a C function that can be included in your own code to configure the tone
generator with the settings being tested.
Environment options
To run tonedebug using the settings specified with the VPB_TONE environment variables,
call it with the -e option. For example:
$ tonedebug -e --port 4 -w my.wav
Will use the enviroment settings to try and detect tones from my.wav played into port 4 of
card 0. There are no other options specific to this mode.
Continuous tone options
If passed the -c option, then the tonedebug utility will test parameters suitable for a
continuous tone. For example:
$ tonedebug -c 425 100 2000 -w dialtone.wav -t dial
Will try to detect 2 seconds of 425Hz tone from dialtone.wav, played into port 0 of card
0. If it succeeds it will report a dial event. The following additional options may be
used in this mode:
-c center-freq bandwidth duration
Specifies the primary tone characteristics, its frequency and bandwidth in Hz. and
its minimum duration in milliseconds.
-d center-freq2 bandwidth2
Specifies the second tone of a multi-frequency tone.
-q twist
Specifies the twist of a multi-frequency tone.
-n snr Specifies the acceptable signal to noise ratio, in dB.
-t dial | busy | ringback
Specifies the name of a predefined tone to replace with the given settings.
Pulsed tone options
The -p options will enable testing for pulsed tones. In addition to the common options
and the options for continuous tones, the following options are supported in this mode:
-p center-freq bandwidth on-time
Specifies the primary tone characteristics, its frequency and bandwidth in Hz. and
its 'on' time in milliseconds.
-off off-time
The 'off' time of the pulse in milliseconds.
