Can i change dchan for digium t235 card?

Hi all,

I try to connect my asterisk box (asterisk 11.17.0 with digium card t235) configured as E1 with a Nortel BCM 400, but this box only works with dchan 31, and my asterisk have dchan 16. when i try to change to 31 in my asterisk, dahdi module not loaded in asterisk. forcing the module in asterisk i get this error:

so, i can change the dchan from 16 to 31 in this card?
