Prathap.: Certainly you'll get all kinds of answers in terms of order of magnitude compleity WRT core material properties over frequency/temperature and flux swing (more I'm sure). In addition capacitice effects turn-turn, winding-winding, coupling, essentially a Disertation. I'll send you a diagram showing how to make a SPICE model, the net list for both Schematic A & B. These will be reasonably accurate for the ethernet transformer you are looking at. Also if you have decent impedance analyzer, you can adjust the values in the model to closely match the values you measure with the anayzer.
