Question : How to configure dahdi channels

I'm switching from zaptel to dahdi and am having problems configuring the channels.

When I connect the channel bank to the Digium card, dahdi_tool shows the alarm on the span going from RED to YEL to UNCONFIGURED

What am I missing or doing wrong?

Current config:

[root@021asterisk101 ~]# /usr/sbin/dahdi_hardware
pci:0000:07:08.0     wct4xxp+     d161:0420 Wildcard TE420 (4th Gen)

[root@021asterisk101 ~]# /sbin/lsmod | grep wct4xxp
wct4xxp               348640  0
dahdi                 196168  5 wct4xxp


[root@021asterisk101 ~]# cat /etc/dahdi/system.conf

span=1,0,0,esf,b8zs
span=2,0,0,esf,b8zs
span=3,0,0,esf,b8zs

loadzone        = us
defaultzone     = us

Answer : How to configure dahdi channels

The solution was to add these 3 missing lines to system.conf

fxoks=1-24
fxoks=25-48
fxoks=49-72

I feel dumb now since those are basic/required settings that I always configure in zaptel.conf and should have known that they needed to be in system.conf.
