<div dir="ltr">Hello All,<br><br> I have a Digium Wildcard TE410P Quad-Span T1 Card, when I do connect T1 lines it goes in RED. When I do connect the same line on a different Server (Same Model T1 Card) it works fine. How do I examine/diagnose my T1 Card for any hardware failures. I heard about loopback test , how helpful it is?<br>
<br> Here are my configuration<br> /etc/zaptel.conf<br> span=1,1,0,esf,b8zs<br> bchan=1-23<br> dchan=24<br> <br> Zaptel Configuration<br> ======================<br> SPAN 1: ESF/B8ZS Build-out: 0 db (CSU)/0-133 feet (DSX-1)<br>
