isdnsync question

hi list, have to sync one of my bs-11. got the hfc-s card and soldered the 2 wires. is any driver needed for the hfc-s? or is the clock always on c4io and f0io once the card is plugged in? the hfcmulti driver loads the e1 card, i have a bmask and a dmask parameter in modprobe.conf. should i remove them or just hang on the "type=0x00800"? i have only one try, so i want to clear all possible problems before T. -- Wer Rechtschreibfehler findet, darf sie behalten!
