chan_capi does not set the NT-mode. Your cards driver need to do that.
E.g. for Eicon DIVA Server cards, you just set the '-x' option with divactrl
or set NT-mode in the config wizard.
chan_capi does not (need) to know anything about what protocol the card is 
doing. CAPI is independent here.
Anyway, if the card is set to NT mode, you should specify ntmode=yes
in the capi.conf to tell chan_capi to handle the progress better
(get progress tones).

capi driver? I think you mean chan_capi? Yes it does support
TE and NT mode, as well as DSS1, 1TR6, JAPAN, NI1, QSIG, 5ESS, and a lot 
more protocols.
The card and the cards driver need to support/provide this.
