</div></div>The link between the Asterisk boxes must not be terminated on both<br>
ends. Termination resistors on both ends is practically guaranteed<br>
to cause link issues.<br></blockquote><div><br>Very interesting but I'm afraid I still don't get it.<br><br>For various reasons, my goal is build an asterisk + patton solution that will be later plugged into 8 BRIs like this (hoping my ASCII art will work) :<br>
<br>Patton ------------ x4 BRI ----------------PSTN<br>| |<br>| |<br>Asterisk1 -------- x4 BRI--------------------<br><br>
The box Asterisk2 ast I referred to it previously, is here to behave as the PSTN.<br>As a consequence, I tought that :<br>1. I should set each Asterisk2 port as NT/PTP.<br>2. I should set each Asterisk1 and Patton port as TE/PTP/Term to be as close as possible to target conditions.<br>
<br>Do you agree with this ?<br><br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>
Also make sure that clocking is only supplied by one side of the link.<br>
(The Asterisk1 clock should be slaved to Asterisk2 which should be in<br>
slaved to the Patton link.)<br>
