I thought that, with PRI, it was possible to play using a single E1/T1 port and a T1/E1 loopback adapter (a RJ45 plug with properly assigned wires which makes any outgoing call an incoming one on another PRI channel) ?<br>
<br>For lab testing, this kind of trick seems very useful.<br>I've never tried it yet but is it correct ?<br><br>Cheers<br>
