PROGRAM:
NAME
proslicerl - Measure the echo-return loss on Voicetronix FXS telephony modules
SYNOPSIS
proslicerl [options]
DESCRIPTION
The proslicerl utility tests the echo-return from a handset connected to a Voicetronix FXS
module, such as those used on the OpenPCI range of cards. It can scan all available
impedance values to find the best match for a particular handset.
When running this test the handset must be off-hook and should have the microphone well
muted for the duration of the test.
A series of tones will be played down the line to determine the ERL in several parts of
the audio spectrum. You should avoid creating any other noise on the line while this test
is running, or the results may be skewed.
If no --impedance is specified, and the --scan option is not used, then the default
impedance value (based on the port's country selection) will be used.
OPTIONS
The following options are available:
--help, -?
Show summary of options.
--card number
Explicitly select the card to test. Default is card 0.
--port number

--impedance number
Test a particular impedance setting [0 - 7].
--scan Test all available impedances.
--playgain db
Set the hardware play gain. Values may range from -12.0 to 12.0.
--recgain db
Set the hardware record gain. Values may range from -12.0 to 12.0.
