This is wrong, in both T568A or T568B ethernet pins 1/2 and 4/5 runs on 
a properly twisted pair. Also 120 Ohm impedance is matching the ISDN pri 
specification.
If a straight pri cable is needed then a straight ethernet cable fits 
the job (not the same for a pri cross cable vs an eth cross cable).
