[asterisk-users] can not load chan_dahdi.so from asterisk!

[lizhong zhu]

hello, all of users:
i have a problem with loading chan_dahdi.so. when i start asterisk, it always reports the can not open channel 1 in ...
here is my setting: in etc/system/dahdi.conf:
# Global data
fxsks=1
fxsks=2
fxoks=3
fxoks=4
loadzone        = us
defaultzone     = us
--------------------- in my chan_dahdi.conf---------------
group=0
signalling=fxs_ks
context=from-internal
channel => 1
channel => 2
signalling=fxo_ks
context=demo
channel => 3
channel => 4
----------dmesg----------------
dahdi: Registered Span 1 ('WCTDM/4') with 4 channels
dahdi: Span ('WCTDM/4') is new master
Freshmaker version: 71
Freshmaker passed register test
Module 0: Installed -- AUTO FXO (FCC mode)
Module 1: Installed -- AUTO FXO (FCC mode)
Module 2: Installed -- AUTO FXS/DPO
Module 3: Installed -- AUTO FXS/DPO
Found a Wildcard TDM: Wildcard TDM400P REV E/F (4 modules)
---------------------------------
one error is that there is no transcode under /dev/dahdi, i do not why.
[root at new-host-13 dahdi]# ls
1  2  3  4  channel  ctl  pseudo  timer
[root at new-host-13 dahdi]#
and load from asterisk:

==========================
any one has idea for that problem? 
the second question is about modprobe the modules.  is the ztcfg command still workable  for DAHDI? it always opens zaptel.conf file.  what is the steps to load modules:
--- like this------
modprobe dahdi
modprobe wctdm
ztcfg -vvvvvvvvvvvvvvv; but my one open zaptel.conf file, i installed zaptel before. it should open dahdi.conf. 
i am still investgating DAHDI for further testing. thanks!
