The active cards do the ISDN protocol stuff on board, so the host CPU/driver does not need to do that -> better performance, less interrupts. The AVM cards do not have such DSPs on board, so no echo-cancel. But the Eicon DIVA Server cards do. They do analog Fax/Modem, echo-cancel, DTMF-detection, voice codec, line interconnect/mixing even to other cards, ... with the on boards DSP. chan_capi-cm is supporting most of the features and will do more soon.
