NAME dahdi_monitor - checks the rx/tx levels of DAHDI channels SYNOPSIS dahdi_monitor channel number \[-v\] \[-f FILE\] DESCRIPTION dahdi_monitor monitors a DAHDI channel. It gives you a visual represen- tation of the sound strengths and makes it easy to see if the received or transmitted signals are too high or out of balance OPTIONS The first (mandatory) parameter is the number of the channel to moni- tor. -v Display visual audio levels. -f FILE Write output to FILE Some extra, yet undocumented, options.
