Yow and Huh?

I have test 3.0GHz systems - Intel Desktop board.

I've been testing with a TE405P with looped ports - 1 to 3, 2 to 4.  My 
test is 20 second long calls with one side playing music on hold, the 
other playing gsm prompts.  All channels full (60 calls out, 60 in).

The system runs just under 40% CPU load - 1/2 system time, half user.  
This is with echo cancellation turned off.

Incidentally, I successfully ran more than 3,000,000 calls through this 
hookup over a week and it was completely solid.

I did try two TE405P with 8 looped spans - that did pretty much use up the 
CPU, but subjective call quality was still fine.
