<div>Hi,</div>
<div> </div>
<div>I've been trying to get a signalling link up from a test libss7 build to an ISUP (White Book) Simulator/Emulator. The Asterisk box is using an old E100P single E1 card with a cross over cable to the simulator. After loading zaptel and wct1xxp I have started Asterisk and layer 1 is good (loss of signal and remote alarm functions work as expected). The bad news is that I cannot see any SIO/SIOS messages being returned from the libss7 machine.
</div>

<div>To prove the I/O from the SS7 simulator I have looped back its E1 and watched as the link starts to emergency align but it fails (obviously) because the point codes clash when the signalling link test messages (SLTM) are sent.
</div>
<div> </div>
<div>The question is, does anyone know if there any debug facilities available within libss7? It's much to early to expect something similar to the 'pri debug' command but hopefully there is something that will help to show what libss7 is transmitting and receiving. Also, if a good libss7 build is looped back on itself will it start to align and write messages into a log file or to the Asterisk console?
</div>

<div>Just in case I have made a mess of the libss7 configuration I have uploaded a copy of the config files and span status here:</div>
