<DIV><SPAN class=878414917-13052005><FONT face=Arial color=#0000ff size=2>Run
ZTTEST in /usr/src/zaptel. Your output should be 99.98XXX% or higher. If it
isn't the corruption is most likely because of IRQ misses by the card. Run it
for a couple of minutes. Your "worst" should be 99.98XXX%. Subtle timing errors
and IRQ misses that are not audible will screw up a fax. Also timing errors
on your PRI are another cause. You have to ensure your card is recieving timing
correctly by the telco. and your span is set up appropriately to reflect that.

the usual things are true: turn off any service you do not absolutely need,
disable Hyperthreading in the CPU, turn off any device that you do not need,
such as sound card, USB interface, serial ports, parallell ports, everything you
can think of is off. </FONT></SPAN></DIV></BODY></HTML>
