Pin 1
Pin 2
Pin 3
Pin 6
In these two connection types, Pin 1 and Pin 2 are in a twisted pair, and so are Pin 3
and Pin 6. Since RC907/908-EV35 interface converters support MDI/MDIX
auto-sensing function, users can adopt either kind of the above cables.
4. The V.35 interface adopts HDB26 female connector，the definitions are as
follows:
