[asterisk-users] T1 Card RED ALARM

[arun kumar]

Hello All,

    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?

    Here are my configuration
    /etc/zaptel.conf
    span=1,1,0,esf,b8zs
    bchan=1-23
    dchan=24

    Zaptel Configuration
    ======================
    SPAN 1: ESF/B8ZS Build-out: 0 db (CSU)/0-133 feet (DSX-1)
    24 channels configured

Thanks
~Arun
