DESCRIPTION

13       dahdi_test  dahdi_test  runs  a  timing  test  in a loop and prints the
14       result of each loop.  The test is as follows:
15
16       It reads 8192 bytes from the DAHDI  timer  device  (/dev/dahdi/pseudo).
17       This  should  take  exactly  8000 ms . It uses calls to gettimeofday(2)
18       before and after that read to check that  indeed  exactly  8000ms  have
19       passed.
20
21       Values  of  100%  and  99.99%  Are normally considered a definite pass.
22       Values of 99.98% and 99.97% are probably OK as well.
