Hi Danny,
We're using A104 cards which reduces the complexity of the necessary
cable (it's a regular T1/E1 cross cable).
In case of a A108, the cable that would come closest to what we're doing
is combining the A108 Straight Thru Y Cable and the A108 Cross-Over Y
Cable (or getting both and connecting them with straight thru F-F
connectors).
Met vriendelijke groet,
Ingmar Steen

Thanks Steve,
I got the picture :) THANK!!!
But my doubt is about the cable, what cable should i use? i have a
Sangoma A108D in one machine (one machine with one card). What cable
should i do? how can i make it?
Best Regards!

Hello my friend Ingmar,
I would like to know the cable you used? how was the connection? i'm
using this one:

Is this ok? what should i do my friend, my problems are "understand" the
fisicall connection :(
Best Regards!!!

Hi DD,
We usually use loopback cables and use the open source SIP test tool
"SIPp" to initiate SIP calls that are sent from one group of 4 ports to
another group of 4 ports.

Onderwerp: [asterisk-users] How to test BIG traffic through
DAHDI/WANPIPEinterfaces
Hello Community,
I need to test or simulate many calls through dahdi/wanpipe, i have a
Sangoma A108D, and i need to test the stability of the
card/drivers/firmwares with a test environment, do you think is
possible?
What should i do? using some loopback cable maybe?
Thanks in advance
DD
I set up two machines with T1 interfaces, and connected the two with an
appropriate t1 cable.
One was acting as a network (master), the other as a subscriber (slave)
(for timing). wrote two dialplans, one for each machine,
that would answer an incoming call on one dahdi line, and call to the
next numbered line on the other
machine. The other machine was similarly outfit. I'd define the
extension for the first line on the t1,
and call it with any phone you desire. That call will cascade into 23
separate interlinked calls. If you are
clever, the last call in should dial another real phone you have
on-hand.
You get the picture... right? Phone A dials the exten to call the
first exten on the other machine. The
dialplan should use the first channel on the t1 to place a call to the
first exten on the other machine.
On the other machine, the incoming call on channel 1 is answered, and
then a dial to the second extension
on the first machine, over the 2nd t1 channel. The first machine
answers, and uses the 3rd channel
to call the other machine and so on till all channels are being
used. The last exten answers and dials
a phone (dahdi or SIP, no matter) that you pick up. Such a looped call
should probably be awful, but
it's going thru 23 t1 channels!
If you have two t1 interaces in a single card (or two cards), then you
do this on one machine.
Another approach: set up equal numbers of FZO and FXS lines, and
similarly loop s single call thru all the
channels.This would require just one machine.
Other approaches would involve running multiple threads to call an
extension and then hang up and
repeating this over and over again on all channels to ascertain the load
placed just by call setup and tear-down.
This kind of load is different than when all lines are just shoveling
data back and forth.
Watch your load averages, your %cpu, your swap, etc, as the tests are in
full swing.
