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
	      Explicitly select the port to test. Default is port 0 of the card being tested.

       --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.
