Yes you can. I have done this for a while. First of all, you need an ISDN card that supports the NT mode. HFC ones work great with ZapHFC drivers (mode 0 = TE, mode 1 = NT). The cable between both systems MUST have 2 100 Ohm resistances. Depending on your PBX, you might need to power up the line or not (100V).
