I connected a E400P to a Colt E1 line in Vienna/Austia last friday.

My settings are (after lots of googling [like: what driver to use for
that card? Answer: tor2] and guessing):

span=1,0,0,ccs,hdb3,crc4
span=2,0,0,ccs,hdb3,crc4
span=3,0,0,ccs,hdb3,crc4
span=4,0,0,ccs,hdb3,crc4
bchan=1-15,17-31
dchan=16
bchan=32-46,48-62
dchan=47
bchan=63-77,79-93
dchan=78
bchan=94-108,110-124
dchan=109
