[asterisk-users] TE121 on Asterisk

[Oguzhan Kayhan]

Hello, I just bought a TE121 T1/E1 card, and now trying to install it on a
1.4.23.1 asterisk with dahdi 2.1.0.4
Actually first everything went on well and i managed to see my card on dahdi.
Here's the output:
#asterisk# dahdi_hardware
pci:0000:04:08.0     wcte12xp+    d161:8000 Wildcard TE121

and this is the scan:
--------------------------
asterisk# dahdi_scan
[1]
active=yes
alarms=RED
description=Wildcard TE121 Card 0
name=WCT1/0
manufacturer=Digium
devicetype=Wildcard TE121 with VPMADT032

framing_opts=ESF,D4

--------------------------
 and this is the proc output

asterisk# cat /proc/dahdi/1

          23 WCT1/0/23 Clear RED (EC: MG2)
          24 WCT1/0/24 HDLCFCS RED
-----------------

I want to change it to E1 instead of T1.
here comes the problem.
Default system.conf under /etc/dundi is:
span=1,1,0,esf,b8zs
bchan=1-23
dchan=24
echocanceller=mg2,1-23
loadzone        = us
defaultzone     = us
------

to make it work as E1, if i write a new span like span=1,1,0,ccs,hdb3,crc4
i got the following error when i type dahdi_cfg
dahdi_cfg -vvvv
DAHDI Tools Version - 2.1.0.2
