Hi<br>
<br>
<br>
<pre>My wildcards TDM 400P's with 8 FXO port(connexts to pstn ) has ticking<br>noise.<br><br>I have followed <a href="http://www.voip-info.org/wiki-Asterisk+Hardware">http://www.voip-info.org/wiki-Asterisk+Hardware</a> .
<br>and make sure wctdm is not shareing interrupt with any other devices.<br>The sever hard disk is a scsi, so i can't run " /sbin/hdparm -u1 /dev/hda1" to avoid harddisk interference.<br>But the ticking is still there, what could cause the problem?
