I set up two machines with T1 interfaces, and connected the two with an
appropriate t1 cable.<br>
One was acting as a network (master), the other as a subscriber (slave) (for
timing). wrote two dialplans, one for each machine,<br>
that would answer an incoming call on one dahdi line, and call to the next
numbered line on the other<br>
machine. The other machine was similarly outfit. I'd define the extension
for the first line on the t1,<br>
and call it with any phone you desire. That call will cascade into 23 separate
interlinked calls. If you are<br>
clever, the last call in should dial another real phone you have on-hand.<br>
<br>
You get the picture... right? Phone A dials the exten to call the
first exten on the other machine. The<br>
dialplan should use the first channel on the t1 to place a call to the first
exten on the other machine.<br>
On the other machine, the incoming call on channel 1 is answered, and then a
dial to the second extension<br>
on the first machine, over the 2nd t1 channel. The first machine answers, and
uses the 3rd channel<br>
to call the other machine.... and so on till all channels are being used. The
last exten answers and dials<br>
a phone (dahdi or SIP, no matter) that you pick up. Such a looped call should
probably be awful, but<br>
it's going thru 23 t1 channels!<br>
<br>
If you have two t1 interaces in a single card (or two cards), then you do this
on one machine.<br>
<br>
Another approach: set up equal numbers of FZO and FXS lines, and similarly loop
s single call thru all the<br>
channels.This would require just one machine.<br>
<br>
Other approaches would involve running multiple threads to call an extension
and then hang up and<br>
repeating this over and over again on all channels to ascertain the load placed
just by call setup and tear-down.<br>
This kind of load is different than when all lines are just shoveling data back
and forth.<br>
<br>
Watch your load averages, your %cpu, your swap, etc, as the tests are in full
swing.<br>
