I've compiled mISDN module into kernel and it loads with hfcmulti.dslot=1 parameter. I think there is no difference between dynamically loadable module and statically compiled in. Also when I did not provide this parameter, nothing worked at all.

Is there any issues regarding processor architecture? I use AMD64 platform, though the system (Debian) has i386 architecture working in compatibility mode.

I'm using both debian on 32bit and 64bit.

Your problem might be related to the actual cabling. I believe it is definitely a layer1 (cabling) or layer 2 (mISDN) problem.

I don't really know any other advice but to double-check the cabling, the jumpers on the E1 board as well as the termination jumpers on the BS-11. Everything has to be set to 120 Ohms.
