dahdi_test(8)		     System Manager's Manual		   dahdi_test(8)

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.

SEE ALSO
     dahdi_tool(8), dahdi_cfg(8), asterisk(8). gettimeofday(2)
