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.<br>
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).<div><div></div><div class="h5"><br></div></div></blockquote><div><br></div><div><br>
