according information I found in google this is a hardware issue but if I connect different E1 from other PBX using the same cable everything works just perfect. The strangest thing is that the Telrad is also works perfectly with other e1.
here is my zaptel conf:

span=1,1,0,ccs,hdb3,crc4,yellow
bchan=1-15,17-31
dchan=16

I tried all the ways to configure zaptel (without crc4, without yellow, different clock sources ) result is the same. Here is my IRQ table

Finally solution is found it was a hardware issue. Its strange but after disabling few devices in BIOS everything works perfect again. But it is absolutely illogical. For one or two years everything was OK why it become problem now? Any ideas?

I have had the same issue and updated the driver to Dahdi instead of Zaptel. It worked like a charm.
