NAME

       dahdi_test — Test if the DAHDI timer provides timely response

SYNOPSIS

       dahdi_test [ -v ]

DESCRIPTION

       dahdi_test  dahdi_test  runs  a  timing test in a loop and prints the result of each loop.
       The test is as follows:

       It reads 8192 bytes from the DAHDI timer device  (/dev/dahdi/pseudo).   This  should  take
       exactly  8000  ms  .  It uses calls to gettimeofday(2) before and after that read to check
       that indeed exactly 8000ms have passed.

       Values of 100% and 99.99% Are normally considered a definite pass.  Values of  99.98%  and
       99.97% are probably OK as well.

OPTIONS

       -v
              Be more verbose: print one line per test.

       -c count
              Run for count times instead of running forever.

FILES

       /dev/dahdi/pseudo
       The device file used to access the DAHDI timer.
