Hi,

I am trying to validate a setup with a sangoma A116 card (16PRI in one
card). I currently have two machines set up, each with a sangoma A116
card. Those are interconnected with crossed PRI cables. One of them is
in NT mode, the other in TE.

The ports are configured in E1 mode, asterisk is all set up and I can
make calls between them, filling up all 480 (16 * 30) channels.

Now, I learned about the pattest and patgen tools that come with
dahdi. As far as I understood I should just run patgen on a channel on
the first machine, and then run pattest on the same channel on the
second machine (assuming port 1 on machine 1 is connected to port 1 on
machine 2) . So:
patgen /dev/dahdi/1 #on machine 1
pattest /dev/dahdi/1 # on machine 2

This however gives a never ending flood of output on the pattest on
machine 2. Am I correct in assuming that this is not a good thing?

Does anyone have any other recommendations on how to validate this setup?

I am running all this on ubuntu lucid, kernel 2.6.32.
Asterisk version 11.5.0
Dahdi 2.6.1
Wanpipe 7.0.3
