Problem with TDM400

Hi, I have a TE410P that’s it’s correctly. I have 31 channels, i only use first span. Now I installed a TDM400 and I started to add channels on 125 (I think that it’s correctly because the four spans of TE410p are 124 channels, it’s ok?).

I have a TDM400 with a X100 on ports 1, 2 and 3, and I have a S110M on port 4. Well with this I have this zaptel.conf:

span=1,1,0,ccs,hdb3,crc4
bchan=1-15
dchan=16
bchan=17-31

fxoks=125
fxsks=126
fxsks=127
fxsks=128

loadzone=es
defaultzone=es

And I think that it’s ok because when I execute modpobre zaplel, modprobe wct4xxp, modprobe wctdm and ztcfg -vvv I haven’t errors or warnings.

But when I execute asterisk I have this error:

Jan 24 15:36:07 WARNING[10084]: chan_zap.c:921 zt_open: Unable to specify channel 125: No such device
Jan 24 15:36:07 ERROR[10084]: chan_zap.c:6879 mkintf: Unable to open channel 125: No such device
here = 0, tmp->channel = 125, channel = 125
Jan 24 15:36:07 ERROR[10084]: chan_zap.c:10307 setup_zap: Unable to register channel ‘125-127’

If I delete all about channel 125 it’s start ok, why?

My zapata is this:

[channels]

switchtype=euroisdn

pridialplan=national

prilocaldialplan=national

signalling=pri_cpe

callgroup=1

pickupgroup=1

context=default

immediate=no

group=2
signalling=fxo_ks
context=default
channel=125-127

group=3
signalling=fxs_ks
context=default
channel=128

What’s the problem? Somebody help me?

Right, with this config channels 126, 127 and 128 are ok:

zaptel:

fxoks=125 (If I change it to fxsks it’s ok when I load the driver)
fxsks=126
fxsks=127
fxsks=128

zapata:

group=2
signalling=fxs_ks
context=default
channel=126-128

If i write something about channel 125 I have the same error.

I don’t know what is the problem…
