<br>My feeling (not based on hard facts yet), is that all 4 channels were not all busy.<br>How can I can check this reading PRI INTENSE DEBUG SPAN (enormous) output ?<br><br>I guess this information should be somehow readable from Channel D .
<br>As PRI INTENSE DEBUG shows both Supervisory and Informational
frames, I guess channel occupation should be in Supervisory frames
which I don't know yet how to read.<br><br>How can I check this ?<br>Regards<br>
