EuroISDN and DAHDI error message with Digium 1TE435 card span 1: Invalid argument

I have changed setting to serve E1 line with Digium 1TE435BF in /etc/dahdi/system.conf file

span=1,0,0,ccs,hdb3,crc4

and appears error message "DAHDI_SPANCONFIG failed on span 1: Invalid argument (22)"

The problem was in missing settings for wcte43x kernel module in /etc/modprobe.d/dahdi.conf file.
I just added to the file
options wcte43x default_linemode=e1

and restarted modules without error message
# /etc/init.d/dahdi  restart

Enjoy!
