Добрый день! Подскажите что не так с конфигурацией карты Digium 122P

[root@localhost apps]# asterisk -vvvrx 'dahdi show status'

Какие еще файлы конфигурации необходимо выложить?

файл /etc/dahdi/system.conf :

span=1,0,0,esf,b8zs - но при замене на span=1,0,0,ccs,hdb3 - выдает ошибку invalid argument (22)
