✨ PROSLICERL ✨

okay bestie, welcome to proslicerl, a lil utility from the Voicetronix Telephony Tools family 💖

🌸 NAME 🌸

proslicerl — the girl who measures the echo-return loss on Voicetronix FXS telephony modules 🎀

🦋 SYNOPSIS 🦋

proslicerl [options]

💅 DESCRIPTION 💅

so. proslicerl is a utility that tests the echo-return from a handset plugged into a Voicetronix FXS module — think the ones used on the OpenPCI range of cards, iykyk. and it can literally scan all available impedance values to find the best match for a particular handset. obsessed. 💖

when you're running this test, the handset must be off-hook, and ngl you should have the microphone well muted for the whole duration of the test. no cap.

a series of tones will be played down the line to determine the ERL in several parts of the audio spectrum 🎶. and bestie, please — avoid creating any other noise on the line while this test is running, or the results may be skewed. it's giving chaos and we don't want that. 🙈

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. periodt. 👑

✨ OPTIONS ✨

the following options are available:

  • --help, -? — show a summary of options. the classic "help meee" moment 🫶
  • --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. main character energy fr fr ✨
  • --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.
