<div>Anyway, refering to <a href="http://en.wikipedia.org/wiki/Integrated_Services_Digital_Network" target="_blank">http://en.wikipedia.org/wiki/Integrated_Services_Digital_Network</a>
/ Basic rate Interface paragraph, my setup includes :<br>
</div>
<div>- a single network termination unit, installed and
managed by telco, is connected to public network through 2
twisted pairs,<br>
</div>
<div>- this unit includes two small electronic cards,<br>
</div>
<div>- each card has two RJ45 sockets,<br>
</div>
<div>- each card is connected through a single Cat5
straight, 1m long patch cord to a single BRI port from my
Patton box,<br>
</div>
<div>- both Patton's BRI ports are managed as a "hunt group"
(for outbound calls),<br>
</div>
<div>- for inbound, I didn't checked but usually, Telco
sends one call on one interface, the next one and the next
interface.<br>
<br>
</div>
<div>So to summarize, (I think):<br>
</div>
<div>- I'm getting ISDN signal from two distinct copper
pairs,<br>
</div>
<div>- it is not an S0-bus.<br>
</div>
</div>
</div>
</div>

"Termination Unit" probably means you get the T reference point and
behind the unit you do have the S reference point with a 4 wire
signal, which would be a standard setup.<div class="im"><br>

<div>Can you elaborate a bit ?<br>

Maybe it is easier if you could mention your country and your
telco. I would guess you are either in France or Belgium, but I
could be wrong. Then we could simply lookup what is relevant for
you.</div></blockquote><div><br></div><div>My telco is Orange in France. <br></div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div text="#000000" bgcolor="#FFFFFF">

<div>I'm using an old Asterisk 1.6.1 version there so I
can't rely on T.38/T.30 gateway feature at the moment.<br>

I said T.30 and not T.38</div></blockquote><div><br></div><div>Yes of course, I was referring to T.38 and completly forgot about pure G711 faxing with Asterisk sending T.30 fax to the Patton gateway,through SendFAX application.<br>

<div text="#000000" bgcolor="#FFFFFF"> and the complete explanation would be
rather technical. In essence a T.30 fax with ecm enabled does not
react nicely to certain signaling errors and pertubations and this
is easy to detect. </div></blockquote><div><br></div><div>I'll try to to send a 10-pages long fax and report here my findings.<br></div><div> </div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
<div text="#000000" bgcolor="#FFFFFF">Most of the time I can guess what the problem is
when I see the type of error. Don't ask me how I learned this. Once
you know what to look for, Asterisk 1.whatever is very reliable as
far as facsimiles go.<span class="HOEnZb"><font color="#888888"><br>
