Hi, CRC errors are caused by bit errors on layer 1. In most cases this is a cable issue. Did you try replacing the cable from the NT1 to the quadBRI? How long is that cable? However if only 1 of the 2 B channels are working then you might have your BRI lines get checked or try a different ISDN device on those lines.
